Introduction

Digital Prototyping A digital prototype is created with Autodesk® Inventor® software and is a digital simulation of a product that can be used to test form, fit, and function. The digital prototype becomes more and more complete as all associated industrial, mechanical, and electrical design data are integrated. A complete digital prototype is a true digital representation of the entire end product and can be used to visualize and simulate a product to reduce the necessity of building expensive physical prototypes.

What is Digital Prototyping? Digital Prototyping gives conceptual design, engineering, and manufacturing departments the ability to virtually explore a complete product before it becomes real. With Digital Prototyping, manufacturers can design, visualize, and simulate products from the conceptual design phase through the manufacturing process, boosting the level of communication with different stakeholders while getting more innovative products to market faster. By using a digital prototype created in Inventor, manufacturers can visualize and simulate the realworld performance of a design digitally, helping reduce their reliance on costly physical prototypes.

What is the Autodesk Solution for Digital Prototyping? Autodesk Inventor software takes manufacturers beyond 3D to Digital Prototyping. With Inventor, you can create a single digital model that gives you the ability to design, visualize, and simulate your products: ■ Design: Integrate all design data into a single digital model, streamlining the design process and increasing communication. ■ Visualize: Create a virtual representation of the final product to review design intent, secure early customer validation, and market products before they’re built. ■ Simulate: Digitally simulate the real-world performance of your product, saving the time and money required to build multiple physical prototypes. Inventor enables manufacturers to create a digital prototype, helping reduce reliance on costly physical prototypes and get more innovative products to market faster. The Autodesk® solution for Digital Prototyping brings together design data from all phases of the product development process into a single digital model created in Inventor.

What Pain Points Does Digital Prototyping Address? The manufacturing product development process today is dominated by islands of competency, each presenting its own technical challenges: ■ In the conceptual design phase, industrial designers and engineers often use paperbased methods or digital formats that are incompatible with the digital information used in the engineering phase. A lack of digital data, compatible formats, and automation keeps this island separate from engineering—the conceptual design data must be recreated digitally downstream, resulting in lost time and money. ■ In the engineering phase, mechanical and electrical engineers use different systems and formats, and a lack of automation makes it difficult to capture and rapidly respond to change requests from manufacturing. Another problem in the engineering phase: the geometric focus of typical 3D CAD software makes it difficult to create and use a digital prototype to validate and optimize products before they are built, making it necessary to build multiple costly physical prototypes. ■ Manufacturing is at the downstream end of all the broken digital processes—the disconnection between the conceptual design phase, the engineering components, electrical, and mechanical— and they receive this analog information in the form of drawings. The result is a heavy reliance on physical prototypes and the subsequent impact on productivity and innovation. ■ Disconnected product development processes make it difficult to bring customer and marketing requirements into the process early so customers can see exactly what the product will look like and validate how it will function before it is delivered. The inability to involve the customer early in the product development process means that the customer can’t validate a design before the product goes to manufacturing. Customer requests for changes become exponentially more expensive to address the further along the product is in the manufacturing process. The result: companies have to build multiple physical prototypes for customer validation.

Introduction

Hasn't the Concept of Digital Prototyping Been Around for Years? Although there has been talk about the benefits of Digital Prototyping for years, the budget for the tools required to build and test a true digital prototype has been out of reach for most manufacturing companies. Digital Prototyping solutions are usually expensive, customized installations for large enterprises. Most out-of-the-box 3D modeling applications provide only part of the functionality needed to create a complete digital prototype.

What is Unique About the Autodesk Approach to Digital Prototyping? Scalable: The Autodesk solution for Digital Prototyping is scalable, flexible, and easy to integrate into existing business processes. Using Inventor to create a single digital model, manufacturers can realize the benefits of Digital Prototyping at their own pace, with minimal disruption to existing productive workflows. Attainable: The Autodesk solution for Digital Prototyping provides an easy to deploy and manage solution for mainstream manufacturers to create and maintain a single digital model that can be used in all stages of production. Cost-effective: Delivering cost-effective software for design and manufacturing workgroups, an Inventor-based Digital Prototyping solution delivers the fastest path to ROI. Autodesk has a proven record of making powerful desktop technology available to mainstream manufacturers.

How Do the Autodesk Manufacturing Products and Technology Drive Digital ----Prototyping? Inventor takes you beyond 3D to Digital Prototyping. The Autodesk solution for Digital Prototyping enables manufacturing workgroups to develop a single digital model, created in Inventor, that can be used in every stage of production—bridging the gaps that usually exist between conceptual design, engineering, and manufacturing teams. This single digital model simulates the complete product and gives engineers the ability to better design, visualize, and simulate their product with less reliance on costly physical prototypes—thereby improving time to market, and increasing competitive advantage. Autodesk provides the interoperable tools required to create a complete digital prototype from the conceptual phase of a project through manufacturing.

The Autodesk® Alias® product line enables you to work digitally from project outset using best-inclass industrial design tools. Capture ideas digitally—from initial sketches to 3D concept models using products in the Alias product line—then share those designs with the engineering team using a common file format, allowing a product’s industrial design data to be incorporated into the digital prototype created in Inventor. Today, the look and feel of a machine or device is more important than ever for consumers, so industrial designers and engineers must share housing and user interfaces early in the process.

With Autodesk® Showcase® software, you can quickly evaluate multiple design variations by creating realistic, accurate, and compelling imagery from 3D CAD data—helping reduce the time, cost, and need for building physical prototypes. You can then interactively view the digital prototype in realistic environments, making it faster, easier, and less expensive to make design decisions. Autodesk Inventor software moves engineers beyond 3D and enables them to develop complete digital prototypes of their products. The Autodesk Inventor family of software provides the powerful —yet cost-effective and easy to learn—desktop technology engineers need to take advantage of Digital Prototyping. Autodesk Inventor software enables engineers to integrate AutoCAD drawings and 3D data into a single digital model, creating a virtual representation of the final product. Using this single digital model, you can design, visualize, and simulate products digitally. The model serves as a digital prototype that is refined and used to validate design functions, helping to reduce reliance on physical prototypes and minimize manufacturing costs. ■ Functional Design: Autodesk Inventor software products combine an intuitive 3D mechanical design environment for creating parts and assemblies with functional design tools that enable engineers to focus on a design’s function, not geometry creation—letting the software drive the automatic creation of intelligent components such as plastic parts, steel frames, rotating machinery, tube and pipe runs, and electrical cable and wire harnesses. Reducing the geometry burden helps engineers spend more time rapidly building and refining digital prototypes that validate design functions and help optimize manufacturing costs.

DWG™ Interoperability: Inventor provides direct read and write of native DWG files while maintaining full associativity to the 3D model without risking inaccurate translations. (DWG from Autodesk is the original format for storing and sharing design data when working with AutoCAD software. With billions of DWG files circulating throughout every industry, it’s one of the most commonly used design data formats.) This gives engineers the freedom to safely reuse valuable 2D DWG files to build accurate 3D part models, then communicate insights gained from Digital Prototyping with partners and suppliers that rely on AutoCAD software.

Dynamic simulation: Autodesk Inventor delivers the best integrated simulation tools in the industry. Tightly integrated tools for calculation, stress, deflection, and motion simulation make it possible for engineers to optimize and validate a digital prototype before the product is built. Simulation is performed based on real-world constraints, so you know you can rely on the simulation results. The dynamic simulation tools in Inventor enable engineers to evaluate multiple potential solutions to a motion problem, making it possible to make the best design decisions and avoid costly mistakes. ■ Documentation: Autodesk Inventor software includes comprehensive tools to generate engineering and manufacturing documentation directly from a validated 3D digital prototype, helping design teams communicate more effectively. Inventor combines the benefits of associative drawing views, so any changes made to the model are reflected in the drawing—with the power and widespread acceptance of the DWG format to help reduce errors and deliver the design in less time. ■ Routed Systems: Inventor software’s automated tools for designing routed systems, including complex tube and pipe runs, and electrical cable and harness design, allow you to create and validate a more complete digital prototype, which helps reduce errors and ECOs prior to manufacturing and get to market faster. ■ Tooling: The tooling capabilities of Inventor software give designers and engineers intelligent tools and mold base catalogs to quickly and accurately generate mold designs directly from a digital prototype. Using the Inventor digital prototype, mold, tool, and die manufacturers can validate the form, fit, and function of a mold design before it’s built, reducing errors and improving mold performance. To help validate and optimize designs before manufacturing, you can use the broad range of finite element analysis (FEA) and simulation tools in Algor simulation software, which will enhance the Autodesk solution for Digital Prototyping. ■

“To be best-in-class is not just about moving from 2D to 3D, but rather to push ahead to digital prototyping to answer questions about your product before you start to build it.” —Start-IT “IDC believes that with its new definition of digital prototyping, Autodesk is offering a product development solution to SMBs that will strengthen their competitiveness and give them the functional tools and processes required to achieve product excellence and profitability for years to come." —Gisela Wilson and Michael Fauscette, IDC “One of the primary reasons manufacturers aim to capture more product information electronically is to digitally prototype their product. As a result, they can reduce physical prototyping and in turn, save time and development costs.” —Aberdeen Group “It [Autodesk] provides a comprehensive range of software solutions for the manufacturing industry including its flagship 3D design offering, Autodesk Inventor. The solutions redefine product design process by supporting and connecting all disciplines of product development, from industrial design to mechanical and electrical engineering, and manufacturing.” —Design News “The ability to not only visualize product development in 3D but also to simulate how that product would perform in the physical world are among the benefits assigned to digital prototyping. Research from consulting firm Aberdeen Group, in fact, shows that the use of digital prototypes for top-performing companies both reduces their product development costs and speeds up how quickly products get to market.” —IndustryWeek “The latest Autodesk manufacturing solutions redefine the product design process by supporting and natively connecting all of the disciplines involved in product development, from industrial design to mechanical and electrical engineering and manufacturing.” —The Manufacturer “The Digital Prototyping approach is now embraced by some important manufacturers who once promoted enterprise PLM, including Boeing. Its new 787 Dreamliner, like the 777 before it, was digitally designed, but the digital definition from engineering was pushed into manufacturing via new processes that replaced DCAC/MRM.” —Nancy Rouse-Tally, Desktop Engineering “Autodesk is doing what it has always been good at—taking a technology idea and giving it the top 80% of functionality at 20% of the price. Digital Prototyping is no different. It takes the idea of ‘expensive’ out of PLM and brings it down to all those other users.” —Rachael Dalton-Taggart, PR, Marketing and the Business of CAD “Before Inventor, it would typically take me 18 months to bring a new design to market,” Jason Faircloth, product manager and designer for Marin Bikes, Inc. says. “The finite-element and motion analysis software have enabled me to almost eliminate physical prototypes. With the software, it’s now nine months, and getting faster—and the product is better. This is our future.” The CAE capabilities of Inventor Professional enabled Faircloth to produce multiple “digital prototypes” so that the time-consuming process of physical prototyping was reduced or eliminated. —Desktop Engineering

Chapter 1: Basic Workflow

Environment Comparisons The AutoCAD Electrical environment differs only slightly from the familiar AutoCAD interface. Along with Electrical-specific commands, other enhancements include Electrical symbol libraries and more powerful search path options. Knowing these differences can help you to learn the AutoCAD Electrical interface more quickly.

About AutoCAD Compatibility AutoCAD Electrical is not just compatible with AutoCAD. It is AutoCAD. AutoCAD Electrical is completely integrated with AutoCAD software, and it shares the same commands and functionality. Automated and enhanced commands have been added to AutoCAD Electrical to help you create schematic drawings. Electrical intelligence is stored in the drawings, mainly in the form of attributed blocks. Because the electrical information is stored in the drawing and not in a proprietary database, you can manipulate the drawings with any program that you can use to edit standard DWG™ files without corrupting the drawing and electrical intelligence.

Familiar AutoCAD Environment The AutoCAD Electrical menu system has many industry-specific tools that automate the electrical control systems' design process. With the familiar AutoCAD working environment, you can use AutoCAD commands in AutoCAD Electrical for normal operations. Many AutoCAD Electrical functions are powerful AutoCAD macros, and other product functions use AutoCAD programming languages to create electrical industry-specific commands. AutoCAD Electrical produces generic AutoCAD objects in generic AutoCAD drawings. Everything automatically created by AutoCAD Electrical can be completed with a sequence of AutoCAD manual operations. Consequently, AutoCAD Electrical drawings can be edited with AutoCAD, or AutoCAD LT®, without corrupting or damaging AutoCAD Electrical functionality.

Symbols and Footprints All AutoCAD Electrical schematic blocks, or symbols, are standard AutoCAD blocks using a combination of attributes and xdata to enhance the block's intelligence. Symbols typically rely more on attributes, while panel layout blocks, or footprints, rely more on xdata.

Symbol as inserted

Exploded symbol

You can create symbols with generic AutoCAD block creation tools or with the AutoCAD Electrical Symbol Builder wizard. The Symbol Builder wizard automates many manual tasks, including the creation, sizing, and placing of symbol attributes. To differentiate between the two types of blocks, schematic blocks are usually referred to as symbols and panel layout blocks are usually referred to as footprints. Both symbols and footprints are referred to as components.

About the Scratch Database AutoCAD Electrical automatically maintains a scratch database, which reflects a project drawing’s intelligence and is updated as the drawings are changed. The database carries a snapshot of the block and attribute information carried in the project’s drawing files so that projectwide functions can be processed more efficiently. There is no need for you to manage the database; the drawing is the data storage area. If the scratch database is lost or corrupted, it is re-created automatically from the data stored in the project drawings.

About the Quick Access Toolbar The tools you access most often vary depending on the industry you work in and your specific duties. To help you work as efficiently as possible, you need to have an understanding of the purpose and capabilities of the Quick Access toolbar.

Definition of the Quick Access Toolbar The Quick Access toolbar is a toolbar located above or below the ribbon. By default it is located above the ribbon just to the right of the Application menu. The Quick Access toolbar contains the tools you want frequent and instant access to. You can customize the Quick Access toolbar by adding and removing tools so only tools you need are listed. You modify the Quick Access toolbar using the options in the shortcut menu.

Example of the Quick Access Toolbar In the following illustration, two different settings for tools are shown in the Quick Access toolbar. The AutoCAD default configuration of tools is shown first and the AutoCAD Electrical configuration is under it. In the AutoCAD Electrical configuration, the user requires frequent access to Previous Project Drawing, Next Project Drawing, and Surfer; therefore, those tools were added for easier and quicker access.

About the Ribbon In AutoCAD Electrical 2010, the location where you access the majority of tools was changed from the toolbars and palettes to the ribbon. In the following illustration, schematic editing is taking place. Part of the Schematic tab on the ribbon is shown with the tools for creating schematic drawings.

Definition of the Ribbon The ribbon is an aspect of the user interface that provides easy access to AutoCAD Electrical tools through a collection of tabs. Each tab contains multiple panels and each panel contains multiple tools. The position and layout of the panels on the tabs and the tools in a panel are based on the most common frequency of use. Some tools are available after expanding the panel while other tools may be in a flyout, similar to a toolbar. The display and organization of the ribbon follows the idea and workflow of having only the tools you need for the task at hand. Tools for unrelated tasks or tools that are used very infrequently are either not shown or are accessible in a flyout in the panel. If your workflow or designs require a different layout or organization of tools, you can customize the position and appearance of the ribbon, the panels displayed on the tabs, and the tools displayed on a panel.


■

Changing Ribbon Settings and Display Options There are a number of settings and changes you can easily make to customize how you interact with the ribbon and how it is displayed. To set the ribbon and its panels to display the tools you want access to, you need to know what changes can be made and where to make those changes. In the following illustration, the ribbon is shown in its default display and again after making some changes to the way it is displayed.


■

Ribbon Position By default the ribbon is displayed at the top of the application. You can also set the ribbon to be displayed docked on the left or right sides of the application window or set to float anywhere on the screen. In the following illustration, the position of the ribbon was changed from its default top position to be docked on the left. The display of the tools in the panels is also changed to better suit this position.

Ribbon Tab Order If you want the tabs on the ribbon to be displayed in a different order, you can change the tab order by dragging them to a new location. The tab's new position is between the two tabs where you dropped the tab being moved. In the following illustration, the Panel tab is shown in the process of being reordered and after being reordered.

10

■


Tab Display - Full or Minimized The tabs have three different options for how they are displayed. You can set to display all the panels on the active tab, only the panel titles on the active tab, or only the tabs themselves. The primary difference between these settings is the amount of screen area the ribbon covers and how you access a tool on a panel on a tab. When set to show the full ribbon, with the proper tab already active, you start a tool by clicking the tool on the panel. When set to display only the panel titles, prior to clicking the tool, you first move the cursor over or click the panel where the tool resides. When set to display only the tabs, you first click the tab and then the tool on the panel.

Lesson: Basic Workflow Understanding the basics of the design process can help you when you adapt AutoCAD Electrical to your design methods and standards. This lesson describes the basic workflow of AutoCAD Electrical design. Although some methods are used more often than others, many methods are available. For example, you may start with a panel layout to determine and order components that require a long lead time. Then you can extract a component list from the panel layout to design the schematic. Or maybe you design your schematics in a point-to-point style, laying out components in empty areas of the drawing and then connecting the components with wires. AutoCAD Electrical automatically connects these components as wires are drawn across them.


Describe and perform many of the basic steps necessary to complete an electrical design.

Lesson: Basic Workflow

Chapter 2: Project Basics

About Project Files Usually an electrical project requires more than one drawing to convey all of the necessary design information. In AutoCAD Electrical, you use a project file to manage the group of drawings.

Definition of a Project File A project file is an ASCII text file with a .wdp extension that stores information about a project. A project file contains some of the following information: ■ Project description lines ■ Project default settings ■ Project drawing list, including: ❏ Complete path information ❏ Drawing description lines ❏ Section and subsection assignments ■ Other miscellaneous catalog and symbol library settings To ensure consistency throughout the project drawings, the project settings you store in the project file are referenced when you create or add new drawings to a project. A single project file can find an unlimited number of drawings located in many different directories.

A project file is not needed if the project consists of a single drawing.

By default, project files are stored in the directory pointed to by the WD_PROJ setting in your environment file, but the project files can be stored in any subdirectory. The location of the project file is used early in the file search path. Custom drawing files, symbol libraries, and other reference files can be stored in the project directory so that you can easily change configurations for separate projects.

Lesson: Project Manager

■

45

Project File Example The following is an example of a typical project file.

Lines starting with "*[n]" are project description lines. Lines starting with "?[n]" are drawing default settings. Lines starting with "+[n]" are projectwide settings. Lines starting with "=" are drawing section labels. Lines starting with "= =" are drawing subsection labels. Lines starting with "= = =" are drawing description lines. Lines without a prefix are project drawing files.

For more details on what is contained in a project file, go to AutoCAD Electrical Help > Index > Projects, File Formats.

46

■


Relative Drawing File Paths Relative path information is used to save the drawing file location. If the drawing is stored in the same directory as the project file, only the file name is stored in the project file. If the drawing is stored in a different directory than the project file, the drawing name information includes both the file name and complete relative path information. In the following example, the project file and first drawing are stored at C:\Documents and Settings\All Users\Autodesk Learning\AutoCAD Electrical 2010\AOTG\Settings and Configuration\. The second drawing is stored at C:\Documents and Settings\All Users\Autodesk Learning\.

A project drawing file that is stored in the same directory as the project file. Only the drawing file name is listed. A project drawing file that is stored in a different directory from the project file. Relative paths are added to the drawing file name. In this example the double periods ".." are a DOS command meaning move one level up in the directory tree structure. Store the project file in the same directory as the project drawings. Although this is not required, it allows the project to be moved to different directories or entered into file management programs, such as Autodesk® Vault, with little or no management of file paths. Absolute or fixed paths to drawing files can also be used. To use an absolute path to a drawing file, you must manually edit the project file using any text editor. You cannot enter a fixed path using the Project Manager.

Guidelines for Project Files Follow these guidelines when working with project files. ■ A single project file can have drawings located in many different directories. There is no limit to the number of drawings in a project. ■ Although you can use any text editor to edit a project file, in most cases it is recommended that you use the Project Manager to make changes. ■ The recommended location for the project file is in the same directory as the project drawing files. ■ When archiving or backing up the project drawing files, it is helpful to include the project file.

About the Project Manager An electrical project can consist of dozens or even hundreds of separate drawing files. Managing all of these files, keeping them in the correct order, and so on, can be a time-consuming task. To efficiently maintain these files you need to understand what functionality the Project Manager can provide and how to use it.

Project Manager with the project, expanded drawing list, and current drawing in bold

Project Manager Definition You use the Project Manager to open, close, and activate projects. You also use the Project Manager to add, delete, and reorder drawings in a project file. The Project Manager uses a tool palette style interface called an Enhanced Secondary Window (ESW) to manage the project files and drawings. The behavior of the Project Manager ESW is very similar to other AutoCAD® tool palettes. You can dock the Project Manager at different locations on the screen or hide it until you want to use the project tools.

Project Descriptions You can enter an unlimited number of project description lines. Information you enter can be reused in Bill of Material, Component, and Wire reports that are generated for the project or mapped to your drawing's title blocks. To include project description line information in reports, select the In Reports check box.

AutoCAD Electrical uses a WDL file that defines edit box title lines that you can use instead of the generic Line 1, Line 2, Line 3 references. These titles are usually matched to your drawing title block attributes. On the Project menu, the Title Block utility can update your title block with project description and drawing description information. When the WDL file is used to relabel the edit boxes, you can see how the information in the project description lines is related to the title block. For more information on the WDL file, see AutoCAD Electrical Help > Project-Wide Tools > Title Block Utility > Link Information to the Title Block > Procedure > Customize LINEx Labels.

Lesson: Project Drawing List

■

Definition of the Drawing List Drawings referenced by a project are stored within the project file as a drawing list. There is no limit to the number of drawings in a project. The drawing list, and the drawing order in the list, is referenced during projectwide operations including tagging and report generation. The drawing order is also used when drawings are opened sequentially. Included in the project file along with the drawing file name is the path to the drawing file relative to the project file location. A project file can have drawings located in many different folders. If the drawing file is stored in the same folder as the project file, no path information is included.

Project_Basics_IEC_01.dwg in bold as current drawing

Example Use of the Drawing List A new project you are starting has specifications that match parts of previous projects you have created. You start a new project, adding drawings gathered from the previous projects. After the drawings are added to the new project, you reorder the drawings into logical groupings such as schematic, panel, and machine layout drawings. You also reorder the drawings to match the flow of the schematic design. For example, all drawings with PLC input modules are ordered sequentially.

62

■


Creating New Drawings You frequently need to create new drawings for use with your projects. You can complete a new drawing by using standard AutoCAD commands to create and save the drawing, and then using AutoCAD Electrical commands to add the drawing to the project. You can simplify this process by using the New Drawing command.

Command Access New Drawing

Project Manager: New Drawing

Project Manager shortcut menu: Right-click in the Projects list. Click New Drawing.


■

63

Creating New Drawings To create a new drawing and add it to your project, you use the New Drawing command. This command displays the Create New Drawing dialog box, which combines all of the drawing settings and startup options in a single dialog box. Drawings created with the New Drawing command are automatically added to the active project at the end of the drawing order, and the title block update routine is completed on each new drawing.

Procedure: Creating New Drawings The following steps describe how to create a new drawing, set some of the drawing properties, and automatically add the drawing to the current project. 1.

64

■

In the Project Manager, start the New Drawing command.


2.

For Name, enter the drawing name.

3.

Note: You must enter a name. For Template, click Browse. In the standard AutoCAD Select Template dialog box, select a template for the new drawing.


■

65

66

4.

Under Location, the directory of the active project file is listed by default. Click Browse to select a different location for the new drawing.

5.

Enter the drawing description information.

6.

Enter the IEC style designator information.

■


7.

Enter the sheet value information.

8.

Click OK to create the new drawing, or click OK - Properties to create the drawing and open the Drawing Properties dialog box.

Other than the Name and Template fields, you can edit any of the fields later using the Drawing Properties command.


■

67

Editing the Project Drawing List Frequently during a project design you need to edit the project drawing list. As the project specifications change you need to change the drawings and the order in which they are referenced. The order of drawings in the list determines how AutoCAD Electrical processes the drawings during projectwide operations, such as resequencing and wire numbering.

68

■


Command Access Using the Project Manager, you can add, remove, and change the order of drawings in the drawing list. The Project Manager is the only feature in AutoCAD Electrical that enables you to access these functions. Right-click the project name to display a context menu containing the available commands.

Project Manager shortcut menu displaying drawing list editing commands Use Add Drawings to add multiple drawings to your project. Use Reorder Drawings to change the drawing display and processing order. Use Remove Drawings to remove multiple drawings from your project.

Procedure: Adding Drawings The following procedure describes how to add drawings to your project.

70

1.

Open the Project Manager.

2.

Right-click the project to which you want to add the drawings. Click Add Drawings.

3.

In the Select Files to Add dialog box, select the desired drawing files. Click Add to add the selected drawings to the project. The added drawings are inserted in the drawing list at the end of the drawing order.

■


4.

Reorder the drawings as required.

Two projects can reference the same drawing file; however, doing so can lead to conflicts. Each project attempts to process the drawing according to its own requirements. The last project to process the drawing overwrites any changes from previous projects.

Procedure: Removing Multiple Drawings The following steps describe how to remove multiple drawings from your project. 1.


2.

Right-click the project from which you want to remove the drawings. Click Remove Drawings.


■

71

3.

In the Select Drawings to Process dialog box, select the drawings from the Project Drawing list that you want to remove.

4.

Click Process V to move the selected files to the Drawings to Remove list. Click OK.

Procedure: Removing Individual Drawings The following steps describe how to remove individual drawings from your project. 1.

3.

Right-click the drawing to be removed. Click Remove.

Removing Is Not Deleting Removing drawings from a project does not delete them. It removes only the reference to the file from the project.


■

73

Procedure: Changing the Drawing Order The following steps describe how to reorder the drawings in a project.

74

1.

In the Project Manager, in the Projects list, right-click the project name. Click Reorder Drawings.

2.

In the Reorder Drawings dialog box, select the drawing whose position you want to change. Click Move Up, Move Down, or Sort, as necessary, to reorder the list.

3.

Use the Sort option to choose between alphanumeric or numeric-alphanumeric sort orders. You can sort the drawings by reference, section, subsection, and file name.

■


No Drag-and-Drop Editing The Projects drawing list does not support drag-and-drop editing.

About Drawing Descriptions and Sections Some projects are so large that it is difficult to keep track of all the drawings, what the drawings contain, and where the drawings are used. To effectively work with these larger projects, you need to learn about the tools available for describing and grouping the drawings.

Drawing Descriptions You can add up to three lines of description for each drawing to the project file. They are stored only in the project file and do not change the drawing itself. You can reuse these drawing descriptions in drawing title block attributes and associate them with AutoCAD Electrical reports.

Section and Subsection Codes Especially in projects with large numbers of drawings, it can be helpful to separate groups of drawings into sections or even subsections. The software can search for and process these groupings of drawings during projectwide operations. This information is stored only in the project file and does not change the original drawings.

You do not have to use the section and subsection codes in sequence. There is no fixed relationship between the two codes. Depending on your company standards, you might not use section codes at all and might use only subsection codes for identifying your drawings.


■

75

Section and Subsection Example You can use the section and subsection codes to group your drawings for reports, plotting, and other functions. For example, add section codes of infeed and outfeed to the appropriate drawings. When creating reports, you can sort on the section code and create a Bill of Material report from only those drawings marked as infeed.

Adding Drawing Descriptions and Sections There are times when the drawing file name may not include enough information to easily identify the drawing. You can add drawing description and section information to aid in the identification and grouping of the drawings.

Command Access Drawing Properties

Ribbon: Schematic tab > Other Tools panel > Drawing Properties

Menu Bar: Projects > Drawing Properties Shortcut menu option: Project Manager, right-click drawing name; click Properties > Drawing Properties

76

■


Procedure: Adding Drawing Descriptions and Section Codes The following steps describe how to add or change the drawing description and section codes. 1.

Start the Drawing Properties command.

2.

On the Drawing Settings tab, under Drawing File, enter drawing descriptions.

3.

Enter section and subsection codes.


■

77

You can designate the drawing as a reference file only to exclude it from tagging, cross-referencing, and reporting functions. Drawings designated as reference files are included in projectwide plotting and title block update operations.

You can reselect and edit entries in the drawing properties at any time. This can save time and improve accuracy when reentering the information for another drawing.

Changing the Drawing List Display Depending on company name conventions, a drawing file name itself may not help to identify the information contained on a drawing. To aid in identifying the drawings in the drawing list, you can display more information about the drawing files. To have this extra information appear, you need to know how to edit the drawing list display.

Lesson: Moving Through Projects This lesson describes how to open drawings in three ways that are different from the standard AutoCAD commands: ■ Selecting a drawing from the Projects drawing list in the Project Manager. ■ Navigating to the previous or next drawing in the list. ■ Using the Surf utility to search through drawings for component references with characteristics you specify.

Overview of the drawing-opening tools: Project Manager, Surf, and Previous Drawing and Next Drawing AutoCAD Electrical 2006 and later versions support the Multiple Document Interface, or MDI, standard. With an MDI application, such as AutoCAD Electrical, you can open several files at the same time.

90

■


Objectives After completing this lesson, you will be able to: ■ ■

■

Select and open drawings from the Project Manager. Move between sequential drawings in the active project using the Previous Project Drawing and Next Project Drawing tools. Use the Surfer tool to quickly locate and open project drawings based on component references.

Selecting Drawings Using the Project Manager Especially with projects containing large numbers of drawings, you may want to open drawings scattered throughout the drawing list. To do this quickly and easily, you need to learn how to use the drawing list in the Project Manager for this purpose.

Lesson: Moving Through Projects

■

91

Procedure: Opening Drawings Using the Project Manager The following steps describe how to open a drawing from the drawing shortcut menu in the Project Manager.

92

1.

In the Project Manager, double-click a project to expand the drawing list.

2.

Browse to the desired drawing file name in the list.

■


3.

To open the drawing, double-click the drawing name, or right-click the drawing name and click Open.

This method opens the selected drawing but does not close other drawings that are currently open.

This method is recommended when browsing among drawings scattered in the drawing list.


■

93

About Opening the Previous or Next Project Drawing Schematics are most commonly organized and connected in a linear fashion with wires connecting from one drawing to the next sequentially. The design process usually follows this pattern also. To move between drawings sequentially, as the design process dictates, you use the Previous Project Drawing and Next Project Drawing tools.

Command Access Previous Project Drawing

Quick Access toolbar: Ribbon: Project tab > Other Tools panel > Previous Drawing

Toolbar: ACE: Main Electrical 2 > Previous Project Drawing Next Project Drawing

Quick Access toolbar: Ribbon: Project tab > Other Tools panel > Next Drawing

Toolbar: ACE: Main Electrical 2 > Next Project Drawing

94

■


Previous and Next Project Drawing Command Options When you use these tools to move to the previous or next drawing, any unsaved changes to the current drawing are saved, the drawing is closed, and the requested drawing is opened. To not save and close the current drawing, and only open the requested drawing, you press and hold SHIFT while selecting the command. These tools are available only when the current drawing is referenced from the active project. The commands are disabled if the current drawing is not from the active project.

This method is recommended for moving sequentially between drawings in the project drawing list.

Searching Project Drawings Using the Surfer Tool During the design of a project you may have the need to search for insertions of specific objects, such as components, wire numbers, or catalog number assignments. To accomplish this task quickly and easily, you need to understand how to use the Surfer tool.


■

95

Definition of the Surfer Tool You use the Surfer tool to move through drawings to panel, pneumatic, and schematic component locations. You can surf to related components based on a component tag, catalog number, or wire number. You specify surf criteria by selecting an existing component reference or by entering reference information manually. Wild-card characters are supported during manual entry. Once you have identified the surf criteria, the Surfer tool scans the project drawings and returns a list of all component references found. When you click a found reference, AutoCAD Electrical saves and closes the current drawing, opens the drawing that contains the reference, and zooms in on the selected component. You can quickly edit the component and return to the Surf list for further surfing and editing.

Surfer zoomed in to selected component reference Many AutoCAD Electrical reports, such as Missing Bill of Material and Cross-Reference Exception, can be exported to the Surfer tool. You can use the exported Surf list to edit component references.

The Surfer tool is available only when the current drawing is referenced from the active project. The command is disabled if the current drawing is not from the active project.

The Surfer tool is especially useful for surfing through the project drawing list to scattered drawings based on component references.

Surf List Columns and Options The Surf dialog box displays information about each found reference, such as the component type, the state of contacts, the sheet and reference location, and the installation and localization codes. You also have several options available for displaying and editing the found references. The list area columns and some of the other options are shown in the following figure.

The letter X indicates that this reference has been visited during this surfing session. Codes listed in this column identify the type of reference: ■ A blank or empty column indicates that this reference is a child schematic component, such as a relay contact. ■ The letter p indicates that this reference is a parent component, such as a relay coil. ■ The # symbol indicates that this reference is a panel layout component. ■ The abbreviation np indicates that this reference is a panel nameplate component. This column indicates the state of the reference, where applicable: ■ NO indicates that this reference is a normally open contact. ■ NC indicates that the reference is a normally closed contact. This lists the sheet and reference location of the reference. This lists the installation and location codes of the component. You can adjust zoom levels for the current session or save a zoom level for future surfing.

98

■


You can use Edit to modify a selected component reference without canceling the Surfer session. You can use Delete to remove a component from the drawing.

Procedure: Using the Surfer Tool The following steps describe how to search through a project for all related references to the selected data. 1.

Start the Surfer tool.

2.

At the Command prompt either select a component or tag for the Surfer to trace, or press ENTER to manually enter a tag to trace.

3.

If you want to enter a tag manually, in the Type It to Surf It dialog box, enter the trace data.


■

99

4.

In the Surf dialog box, select the desired trace reference from the list. Click Go To.

5.

Click Edit to open the appropriate editing tool for the reference selected, or choose another command option.

Some command options within the Surfer tool require the Surfer to close. When the operation is complete, you use Continue Surfer to return to the last Surf dialog box listing.

Searching for an Existing Component You know that a relay tagged as K74 exists somewhere in your project, but you can't remember which sheet it is located on. To find the relay, you start the Surfer tool, and press ENTER to select manual entry. In the Type It to Surf It dialog box, in the Component Tag box, you enter K74. All references to the relay are displayed in the Surf dialog box. You click Go To to take you directly to the desired component reference.

Guidelines Follow these guidelines when opening projects: ■ When you open a project, it is added to the current Projects list and automatically becomes the active project. ■ You can have as many projects open as you want, but only one project can be active at a time. ■ Keep open only the current projects you are working on. Having many projects open can adversely affect system resources.

Activating and Closing Projects You may have to move between projects frequently during the course of a workday, sometimes within minutes. Because the project files contain important information about the project, you need to learn how to activate projects for reference by AutoCAD Electrical.

Definition of an Active Project AutoCAD Electrical references the active project for symbol libraries, configuration settings, and other resource information. You can have as many projects open as you need, but only one project can be active at a time. The active project is displayed at the top of the Projects list in boldface. In the Projects list, the active project is indicated by a check mark. When you close a project, AutoCAD Electrical removes it from the current Projects list. If you close the active project, the next project in the list becomes the active project.

Copying Projects New projects are rarely started completely from scratch. Almost always, new projects are started by copying existing projects and drawings and then modifying them to match the new requirements. Because you do this so frequently, it is important for you to learn how to use the Copy Project tool.

Copying Projects Manually A typical manual process for starting a new project uses Microsoft Windows Explorer to complete the following steps: 1. Create a new project folder. 2. Copy existing project files into the new folder, including drawings and reference files. 3. Rename each file one at a time. 4. Edit the project file, removing old references and adding new ones.

Copy Project Tool The Copy Project tool combines all of the manual steps into a single wizard-style interface that guides you through the process of copying and renaming project files, including reference files and drawings. All files referenced by a project are copied into the new project folder and renamed accordingly to match the new project name. You can use Find and Replace to rename the drawing files within the project. As the project file is copied, the old drawing paths and file names are replaced with the copied drawing paths and file names.

Command Access Copy Project

■

Chapter 3: Schematic Wiring

About Wires You use objects that represent wires in every schematic design style. In the common ladder and pointto-point styles, lines on a drawing usually represent the actual wires that connect to components in the design. To effectively create schematics, you must learn what defines a wire in the AutoCAD Electrical environment.

Wires Wires are AutoCAD line objects that you place on specific wire layers in the Create/Edit Wire Type dialog box. Other line properties, such as Linetype and Width, can be used in the wire-type definition. Polylines, lwpolylines, and other AutoCAD object types are not recognized as wires.

Wire Networks A wire network is one or more wire segments and optional branches that interconnect and form an unbroken electrical conductor. Wire segments of the network may contain inline components such as terminals, splices, or wire-crossing gaps, as long as these objects do not force a wire number change as the wire passes through them.

Lesson: Wires and Ladders

■

123

Wire Connections When you select a component or branch for the wire start point, connection dots or angled connections are added automatically, as required by the Drawing Properties dialog box settings. The X=Show Connections option, chosen before selecting a wire start point, places a small marker on the component wire connection points currently visible on the screen. Any zoom operation erases the markers. If you choose a component wire connection point with an existing wire already attached, a short angled wire is added to offset the second wire from the original. Placement of the offset wire depends on the second point chosen.

Components with multiple wires attached with angled connections

Connection Tees When connecting wires you can use a variety of connection symbols to help indicate how the wiring should be installed. You can have a default style, which you set in the Drawing Properties dialog box, and later edit that style using the Toggle Angle Tee Markers command. For more information, see Electrical Help Topics. Enter Tee on the Search tab and select Wire Sequencing.

124

■


Wire Connection Tee Options The following illustration shows the various wire-tee options that are available when connecting two wires.

Standard connection dot

Wire tee - angle 1, left

Wire tee - angle 2, left

No connection symbol

Wire tee - angle 1, right

Wire tee - angle 2, right

Wire Trap Distance When connecting to another wire, the two wire segments are considered connected if the end of one wire segment touches or falls within the trap distance of any part of the second wire segment. This can be at the end of the second wire or anywhere along the length of the second wire. When connecting to a component, the component's wire connection attributes are used. The trap distance is 0.025 when using inch units, 0.625 when using millimeter units. For more information about wire connection attributes, click Help menu > Electrical Help Topics. Enter connection attributes in the Search tab. Select Overview of Schematic Attributes.


■

125

Wire and Wire Network Example As shown in the following illustration, wires numbered 10 through 19 are lines drawn between connections on the terminal strip TB-4 and the various components. Because these lines are on a layer defined as a wire layer, they are considered to be wires in the AutoCAD Electrical environment. Wires numbered 11 and 15 are also examples of wire networks that contain several wire segments.

126

■


Inserting Wires Inserting wires into your drawings is one of the most common tasks you perform, and several methods for inserting wires are available. Knowing the correct tools, recommended procedures, and insertion guidelines can help you work smarter.


■

127

Command Access Insert Wire

Ribbon: Schematic tab > Insert Wires/Wire Numbers panel > Insert Wire

Menu Bar: Wires > Insert Wire Toolbar: ACE: Main Electrical > Insert Wire

Insert Wire Options Use the Insert Wire command to add new wire segments to your drawings. The Insert Wire command is similar to the AutoCAD Line command in the following ways: ■ You are prompted for start points and endpoints. ■ You can continue a wire segment by continuing to select points. In addition, the Insert Wire command provides the following functionality: ■ Lines drawn are placed on a wire layer by default. ■ By default, segments are automatically drawn in 90-degree increments. ■ Connections are made automatically to other components or wires.

Inserting a wire with a 90-degree bend between two segments

128

■


If you want to fix the endpoint of the first segment, at the Command prompt, enter C. The Insert Wire command continues the wire from the fixed point, automatically drawing the two perpendicular segments. Unless you select a specific angle with the Insert Wire command, only horizontal and vertical wire segments are drawn. Be sure to have Snap mode turned on when drawing wires and inserting components. This keeps the cursor locked in the position you want and helps to prevent unwanted wire segments from being added due to the automatic 90-degree segments.

You can also use the AutoCAD Line command to insert new wires. Make sure the current layer is set to a valid wire layer. Use the AutoCAD Electrical Insert Wire Gap command if the line crosses another wire and you want to show a gap.

Procedure: Inserting Wires The following steps describe how to insert a wire in your drawing. 1.

Start the Insert Wire command.

2.

If desired, enter T at the command line. Press ENTER to manually set a wire-type layer. Select a wire type from the list.


■

129

130

3.

Select the start point for the wire.

4.

Select endpoints for the wire segments. If desired, enter C at the command line. Press ENTER to select the intermediate endpoints.

5.

Press ENTER to end the wire. The command autorepeats, enabling you to insert another wire.

■


Layer Assignments When you use any command to add wires in your drawings, the new wires are automatically placed on a wire layer. Knowing the methods used to make layer assignments is essential to creating accurate electrical designs.

Wire Layer Assignments When new wires are added to a drawing, the following wire type layer assignments are made automatically: ■ If a new wire segment is attached to an existing wire, the new wire is placed on the same layer as the existing wire. When a wire segment is added between wires on two different layers, the wire layer at the starting connection is used for the new wire segment. ■ When new wire segments are not attached to existing wire, they are placed on the current layer if it is a valid wire layer. If the current layer is not a wire layer, the new wire segment is placed on the default wire layer as set in the Create/Edit Wire layer dialog box. You can also manually set the default wire layer. Before selecting a wire start point, choose the T=Wiretype option. This displays the Set Wire Type dialog box where you set the wire layer to be used during the command. For more information about the Wire Type command, click Help menu > Electrical Help Topics. Enter Use Wire Layers in the Search tab. You can change the layer assignments of line objects at any time, converting lines to wires and vice versa, by using the AutoCAD Electrical Change/Convert Wire Type utility or by using any AutoCAD properties commands.


■

131

Trimming Wires Existing wires can be edited or erased using a variety of methods. Knowing the available tools and recommended procedures improves your efficiency.

Example of wires with components added

132

■


Command Access Trim Wire

Ribbon: Schematic tab > Edit Wires/Wire Numbers panel > Trim Wire

Menu Bar: Wires > Trim Wire Toolbar: ACE: Main Electrical > Trim Wire

Trim Wire Options Use the Trim Wire tool to remove a wire segment and connection dots, as necessary. You can trim a single wire or draw a fence or a crossing to select multiple wires. When you choose a wire segment to be trimmed, AutoCAD Electrical follows the wire in each direction from your selected point until it finds wire connection points. The wire is trimmed to each point and the connection dot is automatically removed if it is no longer needed. You can also use the AutoCAD Erase or Trim command to remove wires, but the wire connection dots are not removed automatically and might require extra steps to remove them.


■

133

Procedure: Trimming Wires The following steps describe how to trim wires from your drawings.

134

1.

Start the Trim Wire command.

2.

To trim individual segments, select each segment.

■


3.

To trim multiple segments using a fence line, at the Command prompt, enter F. Draw a fence line across all wires that you want to trim.

4.

To trim multiple segments by window-selecting, at the Command prompt, enter C. Draw a crossing window across all the wires that you want to trim.

Nonwire objects are ignored and are not trimmed or erased.

135

About Ladders and Rungs When using ladder-style design methods, one of your first tasks is to create the ladder structure for the insertion of components. To complete this task, you need to understand what ladders and rungs are in AutoCAD Electrical.

Ladder with rungs and wires

Ladders Ladders are a collection of wires joined together to form a matrix. The outside wires of the ladder are referred to as a bus. The inside wires are referred to as rungs. Three-phase ladders are usually created with only the bus wires. Ladders, ladder rungs, and power buses are all wires; you can draw them using the Insert Wire command. However, Insert Ladder and Add Rung commands are available to make the creation of these special types of wires easier. There is no limit to the number of ladders you can insert into a drawing as long as the ladders do not overlap each other. You can insert a new ladder at any time. Multiple ladder fragments in the same vertical column need to be vertically aligned along the left side. Note that these limitations do not apply when X-Y Grid or X-Zone referencing is selected. A single drawing can contain both control ladders and three-phase ladders, each one with a different length, width, and rung spacing, as necessary.

136

■


Ladder Rungs Add Rung is a specialized version of the Insert Wire command. When you select an insertion point, AutoCAD Electrical seeks to the left and to the right, or to the top and to the bottom, depending on the ladder orientation, for bus wires. The rung is inserted, connecting the two buses. Connection symbols are inserted as required. If ladder referencing is used, the rung is placed at the closest line reference location. Do not click directly on the bus wires. This can cause the program to behave inconsistently when seeking a connection to the bus wires. Always click somewhere between the two buses.

Example showing pick points not on buses

Insert Ladder Example The Insert Ladder and Add Rung commands make the creation and editing of ladders much faster. For example, creating a ladder with buses and rungs using the Insert Wire command requires drawing the two buses and repeatedly drawing wires from bus to bus, being careful to start each wire on the correct reference location. Then reference numbers need to be added. The Insert Ladder command does this automatically, even placing all wires on the default wire layer.


■

137

Referencing Locating components within the project drawings is very helpful when troubleshooting or editing your schematics. This is especially true when working with complex drawings and larger projects. Two main types of referencing styles are commonly used: ladder referencing and grid referencing. You need to learn what those types are and how they define locations in your drawings.

Ladder reference example

Grid reference example

Ladder Referencing When using ladder referencing, each rung in the ladder is assigned a number. The number can be in a variety of formats that may include rung number, sheet or drawing number, or several other variables. The first ladder reference number is a master ladder reference (MLR) block. Attributes in this block contain the settings for the ladder. All other reference numbers in the ladder are simple text objects and can be erased without affecting the ladder intelligence. Each ladder in the drawing is associated with a unique MLR block.

Example of ladder referencing with MLR highlighted

138

■


You set the ladder referencing format under Format Referencing on the Drawing Format tab in the Drawing Properties dialog box.

Grid Referencing There are two grid referencing options available, X-Y Grid, and XZone. When X-Y Grid referencing is used the drawing area is divided into columns and rows. This is similar to the referencing commonly used on geographical maps. If XZone referencing is chosen the drawing is divided into columns only. Grid referencing does not place any intelligence on the ladder itself. The grid reference spacing, origin, and vertical and horizontal axis annotation lists are carried on attribute values of the drawing's invisible WD_M block. There is no MLR block, and no reference text values inserted on the ladder.

Drawing with X-Y Grid referencing; Columns sorted by numbers, rows sorted by letters

Example of Ladder Referencing Your company standard is to use a four-character number for each ladder rung. The first two characters represent the sheet number in the project and the last two characters represent the rung number. You set the component tag format to Referencing to use the ladder reference as the tag value When using this method you can identify where a component is in the project drawings by just interpreting the tag value. For example, CR1043 is a control relay on located on sheet 10, rung 43.


■

139

Inserting Ladders and Rungs Inserting ladders and rungs is very tedious if you use manual methods such as the AutoCAD Line or Add Wire commands. For the highest design productivity, you need to understand the tools that help you to simplify these tasks.

Command Access Insert Ladder

Ribbon: Schematic tab > Insert Wires/Wire Numbers panel > Insert Ladder

Menu Bar: Wires menu > Ladders > Insert Ladder Toolbar: ACE: Main Electrical > Insert Ladder > Insert Ladder Add Rung

Ribbon: Schematic tab > Edit Wires/Wire Numbers panel > Add Rung

Menu Bar: Wires menu > Add Rung Toolbar: ACE: Main Electrical > Add Rung

Specifies the width of the ladder between buses.

Spacing

Specifies the spacing between each rung.

Length

Specifies both the length of the ladder and the number of rungs. Whichever one is not entered is calculated automatically. You can enter the total ladder length, the number of ladder rungs, or leave both blank and manually select the beginning and ending points of the ladder.

1st Reference

Specifies the beginning line reference for the ladder. Index is the increment number for line reference numbering (default=1).

Phase

Specifies whether to create a one-phase or three-phase ladder. If you select to create a three-phase ladder, the Width and Draw Rungs options are unavailable.


■

141

Setting

Description

Draw Rungs

Specifies how to draw the rungs. No Bus draws only the line reference numbers, while No Rungs draws only the hot and neutral bus without rungs. Select Yes to include rungs automatically at every reference location (Skip=0). You can specify whether to skip rungs; a value of Skip=1 means every other rung is drawn; a value of Skip=4 means that four rungs are skipped for every one that is drawn.

Procedure: Inserting Ladders and Rungs The following steps describe how to insert a ladder and rungs in your drawing.

142

1.

To insert a ladder, start the Insert Ladder command.

2.

In the Insert Ladder dialog box, click the phase of the ladder--either 1 Phase or 3 Phase.

3.

Enter other ladder options as desired.

■


4.

Select the ladder insertion point.

5.

To add rungs, start the Add Rung command.

6.

Select a rung insertion point.


■

143

Revising Ladders After a ladder has been inserted, changes may be required to match new requirements. To make these changes, you need to understand how to use the Revise Ladder tool.

Command Access Revise Ladder

Ribbon: Schematic > Edit Wires/Wire Numbers panel > Add Rung flyout > Revise Ladder

Menu Bar: Wires > Ladders > Revise Ladder Toolbar: ACE: Main Electrical > Insert Ladder > Revise Ladder

Revise Ladder Options The Revise Ladder tool adjusts the line reference numbering along the side of the ladders; however, it does not change existing ladder rung spacing. You use the Scoot utility or other methods to manage rung spacing. Revise Ladders cannot change the style of a ladder, once it is inserted. For example, you cannot use it to change the reference number formatting from Numbers Only to Sheet and Numbers. To change the style of a ladder, you can use the Swap Block utility to change the master ladder reference block.

144

■


Each line in the Modify Line Reference Numbers dialog box represents a ladder in the drawing. Changing any value in the dialog box automatically selects the Redo check box. Select Redo manually to force an update.

Updating the ladder's reference numbers does not update existing components or wire numbers. Use the Retag Components and Automatic Wire Numbers commands to complete these tasks. Use the AutoCAD Move command to relocate an entire ladder. Make sure that you select the entire ladder, including the very first-line reference number (the MLR block insert). Click Revise Ladder. When the Revise Ladder dialog box is displayed, click Cancel. Using this sequence forces an update of the internal ladder location list.

Revise Ladder Example You inserted a ladder in your drawing but decided that you needed to change the spacing and number of rungs. You start the Revise Ladder command and change the rung spacing from 0.75 to 0.50 and the number of rungs from 7 to 8.

■


Point-to-Point Style Drawings Different industries use different styles of schematic drawings. To create different styles of drawings, you need to learn the differences between point-to-point and ladder style drawings.

Point-to-Point Style Drawings Defined The point-to-point or wiring diagram style of drawings generally refer to the same style of schematic drawing. In this style of drawing the components are placed on the drawing in a freeform manner, many times to display the simplest wire routing and component connections. Some drawings may use the location of the component in the drawing to simulate the location on the machine. This is in contrast to using a ladder style drawing that uses two buses and rungs running between them. The ladder style of drawing generally restricts placement of the components to the buses and rungs. Either style of drawing can be used to represent just about any electrical device. Which one is used is determined by company and industry standards.

Example of ladder style drawing

Example of point-to-point style drawing

Example of Point-to-Point Style Drawings You are working for a company that uses the wiring diagram or point-to-point style of drawings for its schematics. Start to create the drawing by placing components that are located in the front of the machine on the left side of the drawing, and components that are located near the back of the machine on the right side of the drawing. After the components are placed, you insert individual wires between the components, connecting them together.

Lesson: Point-to-Point Wiring

151

Point-to-Point Wiring Tools Most of the standard AutoCAD Electrical commands fully support the point-to-point style of design. In addition, several commands offer functionality to aid in the creation of point-to-point design schematics. To efficiently create these wiring diagrams, you need to know what these tools are and how they are used. Only some of the tools that are especially helpful for point-to-point style drawing creation are presented here. All tools can be useful for both ladder style and pointto-point drawings.

Collision Avoidance and Wire Routing As you insert wires, the software checks for collisions and automatically routes the wire to avoid overlapping existing wires. The following steps describe how to add a 45-degree wire segment. When you start a wire at a wire connection where a wire exists, a short 45-degree segment is added to the new wire to offset it from the existing wire.

Existing wire

■

Start new wire at wire connection point


45-degree wire segment added

When you insert a wire so that it overlaps an existing wire, the new wire is automatically offset to run parallel to the existing wire.

Existing wire

Select new wire points causing overlap

Wire is automatically routed around existing wire

Insert Splice When using the Insert Splice command, the splice symbol is oriented to the wire direction (vertical or horizontal) and connects to the wire. A splice also triggers a wire number change. After the splice is inserted on the wire, the Insert/Edit Component dialog box is displayed so that you can assign catalog numbers and add descriptions and other attribute data.


■

153

Insert Wire When using the Insert Wire command, you select endpoints for each wire segment. The Insert Wire command automatically attempts to create two segments 90 degrees to each other when selecting endpoints. The Continue option is useful. During the Insert Wire process you can enter C and press ENTER at the command line. This ends the first segment at the current corner point and continues drawing the wire from the newly established endpoint.

With first segment ended, Insert Wire command is continued after using the Continue option

Bend Wire Use this command to bend wires around obstacles in the wire path. This command adds a corner to the existing wire, adding new segments to the existing wire. You are prompted to select the bend points on the two intersecting wires. A corner is added between the selected wires.

Multiple Wire Bus The Multiple Wire Bus command has many options, including the ability to connect to a component by windowing the pins on the existing component. In the Multiple Wire Bus dialog box, under Starting At, use the Component (Multiple Wires) option. You are prompted to select pins at the starting connector. With this option selected, you do not need to set the number of wires. This number is determined by the connections you select for wiring during the command. Spacing for the start points of the wires is determined by the connections selected, but the spacing settings are used as the wires traverse the drawing, make turns, and so on. You can start and end connections on more than one component at a time. For example, you can window a series of terminals for a connection to a plug. You can select several pins from one component and create multiple wires that connect to another component. You must use a window for selecting wire connections, but you can select only one pin at a time. The selection order defines the order that the wires connect to the ending connector. The default order at the ending connector can be reversed or flipped by entering F on the command line. Only one symbol orientation can be selected at a time, such as, for example, only horizontal connections or vertical connections. Little green X’s indicate that the available wire connection points are displayed during the selection process. If you zoom, these connection indicators may disappear, but the connection points still exist and can still be selected. If you connect to a device that has multiple connection points, the utility finds the other connection points on the device and automatically connects to them. When connecting to devices with a single connection point, you select each connection point individually.

Lesson: Wire Numbers and Leaders This lesson describes different types of wire numbers, how to change wire-number placement and other options, and how to attach wire numbers and wire leaders to wire networks in your drawing set. Using tools provided in the software, you can automatically add wire numbers to every wire network in the project drawing set with a single command. This is more accurate and faster than adding wire numbers manually using AutoCAD commands.


■ ■ ■

164

Identify different types of wire numbers, describe the purpose of leaders, and describe placement options. Set wire number and leader default options for automatic placement. Automatically add wire numbers and wire number leaders to your drawings. Manually add and edit wire number copies and leaders.

About Wire Numbers and Leaders Wire numbers and leaders are unique labels that identify individual wires and wire networks.

Wire number 06.4 is shown in default location; Wire number 06.5 shown with leader; Wire number 06.6 shown inline

Definition of Wire Numbers Wire numbers are unique labels that identify individual wires and wire networks. A wire number is an attribute attached to an invisible block (a block without graphics). The block is inserted on the wire and the attribute is displayed nearby, depending on the location style chosen. The distance from the wire is determined by the attribute spacing within the wire number block definition. Only one wire number is assigned per wire network. A wire network may have many wire number copies added to it. There are four types of wire numbers: normal, fixed, extra, and terminal/signal. Type

Description

Normal

Updated whenever AutoCAD Electrical executes an automatic wire-numbering command.

Fixed

Locked to current values. They can be edited manually but are not updated during automatic wire-numbering commands.

Lesson: Wire Numbers and Leaders

■

165

Type

Description

Extra

Extra copies of a normal or fixed wire number that are assigned to a given wire network. A wire network has only one normal or fixed wire number, but not both, and may have many extra copies of that wire number inserted at various locations on the network. Extra wire numbers automatically update if the normal or fixed number is changed.

Terminal/signal

For terminals and signal arrows.

Assign different layers and layer colors to each type of wire number in order to identify them easily in your schematic.

Wire numbers cannot be added to a wire network entirely made of wires with the Wire Numbering property set to No. Existing wire numbers can be updated.

Definition of Wire Number Leaders Wire number leaders are graphics that extend from a point on a wire to a remotely located wire number. Wire number leaders indicate where the wire number is attached to the wire.

Examples of wire numbers with leaders

166

■


Leaders are commonly used when the default wire number location is crowded and the wire number collides with other objects in the area.

Arrow indicates wire number leader added due to crowding Leader checks are triggered when you insert wire numbers or recenter them with a move. If the application cannot determine a suitable location, the wire number is left in its original position, and you must adjust it manually.

Wire leaders are placed on the same layer as the associated wire number.

Automatic Leader Options If you set the placement location option to Above or Below the wire you have several options for automatically adding leaders to every new wire number. Use the following options for the automatic placement of leaders. Option

Description

As Required

The application adds leaders to wire numbers when it determines that the wirenumber text is colliding with something. However, it does not determine if the leader itself is colliding with something.

Always

Leaders are added to every new wire number.

Never

Leaders are not added to a wire number even if a collision is detected.


■

167

You can also add leaders to wire number copies.

Wire Number Example While your company standard is to use line referencing for the wire numbers, a customer has requested that the schematic is to have all the wires in the project wired sequentially. You take the standard schematic and run the Automatic Wire Number command. By setting the wire number style to sequential and selecting a projectwide process, you renumber all the wires in the project automatically to the sequential style. Examples of wire numbers applied in a drawing are shown in the following illustration.

Normal, placed above the horizontal wire. Fixed, placed above (to the left of) the wire. This wire number is not changed by any automatic wirenumbering process. Wire Number Copy, placed above (to the left of) the wire. This wire number automatically changes as the corresponding wire number changes. Wire Number Copy, with leader, placed above (to the left) of the wire.

Lesson: Source and Destination Signals This lesson describes how to insert and link source and destination signals in your schematic drawings. AutoCAD Electrical fully supports wire number signals, which can carry a wire number from one location to another, from source to destination. A wire number can jump from one column to the next, from one drawing to the next, or skip around the project drawing set.


Describe source and destination signals and the functionality they provide. Set up and insert source signals, linking them to destination signals.

Lesson: Source and Destination Signals

■

185

About Source and Destination Signals Understanding what source and destination signals are and how they work makes it easier for you to know when and where to place them in your drawings. This knowledge also helps when troubleshooting problems or when working with the drawings without the AutoCAD Electrical software available.

Definition of Source and Destination Signals When a wire is forced to traverse to a remote location, either on the same drawing or separate drawings, you end the wire in the first location, and start a new wire in the remote location. Source and destination signals are blocks with specifically named attributes that you place on the two ends of the wires. You enter matching code values in mating signal blocks. This effectively connects the two separate wires into a single wire network. Source signals provide the beginning or parent link between the two wires. A destination signal is the ending or child link. Properties from the source wire such as wire number and wire type are transferred to the destination wire. Wire numbering will not span across source or destination arrows that include wires with the No Wire Numbering property set to No.

Signal Arrow Examples The illustration shows examples of source and destination signals.

Source Signal Arrow Destination Signal Arrow

Chapter

4 Schematic Components This chapter describes how to use schematic components in your drawings. Several methods are available to insert schematic components. When starting with an empty project, you use the Icon Menu system to select and insert the component symbols. When panel or schematic drawings exist, you can extract component lists to aid the insertion process. You can also use an external component list as an insertion tool. Some tools, such as the Circuit tools and the Multiple Wire Bus tool, provide intelligence and automation to otherwise repetitive tasks.


■ ■ ■ ■ ■

Insert and annotate schematic symbols, add catalog and description data, and create parent-child relationships. Select schematic components for insertion from a panel component list extracted from the project. Describe and insert parametric connectors in your schematic drawings. Describe and create multiple level terminals and terminal jumpers. Create and edit electrical circuits, including moving, copying, and saving them in the icon menu. Insert multiple-phase wires and components into your drawings.

Chapter Overview

203

Lesson: Inserting Schematic Symbols This lesson describes how to use the Insert Component icon menu system to select and insert schematic symbols. You learn how to assign information such as manufacturer and part number, location, and descriptions to the inserted components. You also establish the relationship between a parent component and its contacts, or children. Inserting and annotating components is the basic procedure for building an intelligent schematic. Data from the annotated schematic components is reused several times in places such as panel design and reports.

Chapter 4: Schematic Components

Schematic Symbol Insertion Process Inserting schematic symbols is one of the most basic and frequent tasks in creating an electrical drawing. Most of the information in a schematic is given through the insertion of graphic symbols. You need to understand the basic process and options used to insert symbols.

Insert Component Process The following diagram describes the typical process for inserting components.

Command Access Insert Component

Ribbon: Schematic tab > Insert Components panel > Icon Menu

Menu Bar: Components > Insert Component Toolbar: ACE: Main Electrical > Insert Component Shortcut Menu: Right-click over a wire; click Insert Component > Insert Component

Lesson: Inserting Schematic Symbols

■

205

Inserting Schematic Symbols with Icon Menus Icon menus are the primary user interface you use to select and insert symbols. You use controls in the Insert Component icon menu to manage the insertion of symbols in your schematic drawings. When you are at the main or first page in the menu, entries in the tree view on the left correspond to the icons in the icon symbol menu in the center. For example, the first entry in the list, Push Buttons, corresponds to the icon of a push button shown under Schematic Symbols, and so on. Clicking Push Buttons in either the tree view or under Schematic Symbols highlights Push Buttons in the tree view and displays the Push Buttons icon submenu.

206

■


Menu Controls The following controls are available in the Insert Component dialog box.

Tree view menu - Enables you to maneuver through symbol display pages. Selecting an entry here displays the matching icon page in the Symbol Menu area. Symbol menu - Displays icons of schematic symbols. This is where you select the symbol for insertion. Recently Used - Displays the symbols you most recently used during this session. You can change the number of icons displayed by entering a value in the Display box. Menu - Toggles the display of the tree view. If the tree view is closed, click this button to redisplay it. Up One Level - Displays the previous icon menu page. It is similar to the Back button used in Windows. This button is especially important for maneuvering through symbol pages when the tree view icon menu is not displayed. Views - Displays an option menu for changing the display of the icon menu page. You can select from the following: ■ Icons with Text (default). ■ Icons Only. ■ List View (text with very small icons). Vertical/Horizontal - Toggles the preview orientation of the symbol during insertion. This button depends on the ladder orientation setting in the Drawing Properties dialog box, as follows: ■ If the ladder orientation is horizontal, this button is displayed as Vertical. ■ If the ladder orientation is vertical, this button is displayed as Horizontal.


■

207

No Edit Dialog - Inserts the symbol without displaying the Insert/Edit Component dialog box. The component tag is inserted, but no other component information. Scale Schematic/Panel - Changes the scale factor of the symbols as they are inserted. Type It and Browse - Enables you to enter the name of the symbol in the box or browse to the file location if the component to be inserted is not in the icon menu system but exists as a file.

Symbol Insertion When you select a symbol for insertion, the symbol appears on the cursor as a reference while you select an insertion point. When you have vertically oriented ladders with horizontal rungs, the horizontal symbol appears on the cursor by default. If you choose a vertical wire, the symbol is automatically switched to a vertically oriented symbol for insertion. The opposite is true for horizontally oriented ladders with vertical rungs. A vertical symbol appears on the cursor and is automatically switched if a horizontal wire is selected.

Vertical symbol preview with vertical wire Upon insertion, the schematic symbols break the underlying ladder rung or wire and reconnect. This works if you select directly on the wire or within the trap distance. After the symbol is inserted, you can complete the annotation and insertion of the component in the Insert/Edit Component dialog box.

208

■


If you cancel the insertion process at any time, the symbol is not inserted and the underlying ladder rung or wire is rejoined. This is true even if the symbol has been placed on the wire and the Insert/Edit Component dialog box is displayed.

Left image is during insertion with inserted symbol and broken wire; Right image is with rejoined wire after cancel

About the Insert/Edit Component Dialog Box The Insert/Edit Component dialog box is one of the most important dialog boxes used in your schematic designs. This dialog box is where you enter the component information such as catalog numbers, tag name, and descriptions, and so on, into the component attributes. This information drives almost all the intelligence and automation available in the software. It is important that you understand the options and choices that are available for creating the most intelligent drawings and projects possible.

Insert/Edit Component Dialog Box You use the Insert/Edit Component dialog box for both inserting and editing component attribute values. During the component insertion process, the dialog box is automatically displayed after you select the component insertion point. It is also displayed when you select the Edit Component command. The boxes in the Insert/Edit Component dialog box correspond to attributes found in the component. You can either enter information directly in the boxes or use the labeled buttons to look up and enter the information automatically. You can use any AutoCAD® attribute editing tool to edit symbol attributes. However, the Insert/Edit Component dialog box also provides tools to help fill the attributes with accurate information.

■

211

Component Tag Component tags, such as -06S7, are based on the current drawing configuration settings and are automatically generated during the component insertion process. To define the component tag manually, you edit the existing tag or enter another tag in the box. Select Fixed if you do not want this tag to be updated during automatic retag operations. Other options in this window enable you to search for existing tag entries.

Each component must have a unique tag or identifier.

The tag format is customizable. You set component tag and suffix formatting on the Components tab in the Drawing Properties dialog box.

When a component tag is fixed, AutoCAD® Electrical changes the TAG attribute in two ways: ■ Moves it to the Fixed Tags layer as defined in the Drawing Properties, Define Layers dialog box. ■ Appends an F to it; for example, TAG1 becomes TAG1F.

212

■


Description You can enter up to three lines of description attribute text. If a description line is unavailable, the component you are editing does not carry that attribute.

The following describes the options available under Description. Option

Description

Drawing

Displays a list of descriptions found in the current drawing so you can choose similar descriptions to insert and edit.

Project

Displays a list of descriptions found in the project so you can choose similar descriptions to insert and edit.

Defaults

Opens an ASCII text file from which you can select standard descriptions.

Pick

Prompts you to choose a similar description from a component to edit on the current drawing.

AutoCAD Electrical has an option (on by default), which automatically capitalizes entries in the description lines. To change the setting, right-click the project name in the Project Manager to open the Project Properties dialog box. The option is located on the Components tab, under Component Options.


■

213

Cross-Reference AutoCAD Electrical usually enters cross-reference information automatically as components are inserted and linked together. Under Cross-Reference, you can manually edit the cross-reference information on a component.

The following options are available under Cross-Reference.

214

Option

Description

Component Override

Changes the cross-reference formatting for the component, thereby overriding the settings in the Drawing Properties dialog box.

Reference NO and Reference NC

Contains the cross-reference information for the child contacts of the symbol. Normally, these values are updated automatically as child contacts are inserted, but you can also edit the information manually.

NO/NC Setup

Creates pin list assignments for the component being edited. Normally, these values are copied onto the parent component automatically from the pin list database information (if available) when a matching catalog number is selected. You can also edit the information manually.

■


Catalog Data Sample catalog information is included with the default installation. The information is stored in tables in a Microsoft Access database file (MDB) populated with sample vendor data. Expand and modify these tables to meet your specific bill-of-materials needs. You can use the tools provided with the software or a database program that can read and write the MDB file format. You are not required to have Microsoft Access or any other database software installed when you access the database file.

The following options are available under Catalog Data. Option

Description

Lookup

Opens the component's catalog database, from which you can manually enter or select the manufacturer or catalog values. Search the database for a specific catalog item to assign to the selected component.

Drawing

Lists the part numbers used for similar components in the current drawing.

Project

Lists the part numbers used for similar components in the active project, a different project, or in an external list file.

Multiple Catalog

Inserts or edits extra catalog part numbers to the selected component. You can add up to ten part numbers to any component. These multiple bill-of-material part numbers appear as subassembly part numbers to the main catalog part number in the various bill-of-material and component reports.

Catalog Check

Displays what the selected item looks like in a bill-of-material template.


■

215

Ratings Under Ratings, you can specify values for each ratings attribute. You can enter up to 12 ratings attributes on a component. Select Defaults to display a list of default values.

If Ratings is unavailable, the component you are editing does not carry rating attributes.

Show All Ratings Selecting Show All Ratings displays a separate dialog box specifically for editing the rating values. Use the Defaults option to open an external ASCII text file, which is named Wd_Ratings.wdr by default. You can edit this file to list the values that you use most often.

In the View/Edit Rating Values dialog box, the box descriptions are a combination of the attribute name, and the attribute prompt value. For example, Rating 1 is the attribute name, and Motor Size is the value of the attribute prompt.

Because the tools for handling Ratings attributes are built into the interface, you can frequently use these attributes for the unusual or miscellaneous values you want to store with a component.

216

■


Installation and Location Codes Enter the installation and location codes by entering a value in the boxes or by clicking Drawing or Project.

Drawing and Project searches are available in several areas of the Insert/Edit Component dialog box. They have the same general purpose in all instances. Option

Description

Drawing

Lists the values used for similar components only in the current drawing.

Project

Lists the values used for similar components in the following: ■ Any drawing in the active project. ■ Any drawing in a different project. ■ An external ASCII list file.


■

217

Pins Assigns pin numbers to the pin or terminal attributes that are physically located on the component. The GREATER THAN (>) and LESS THAN (<) keys increase and decrease the value displayed in the box, respectively. Pins 1 and 2 are always displayed. You use the third box (X) for entering all other pin numbers. You use the arrow keys to move between the pins. If pin list information is associated with a catalog number in the pin list database, the appropriate pin numbers are automatically filled in when the catalog number is selected.

The terms Pin and Terminal are used interchangeably when discussing the wire connection points on components.

Switch Positions Under Switch Positions, you can enter descriptions for switches with multiple positions. Positions 1 and 2 are always displayed. You can use the third box for entering all other position descriptions. You use the arrow keys to move between the positions. In the State box, you can enter the normal state of the switch. A common style is to enter the letter O to indicate normally open and the letter X to indicate normally closed, such as, OX.

218

■


Selecting Existing Catalog Part Numbers You can manually enter part numbers and manufacturer information in the Insert/Edit Component dialog box, but this can be a tedious and time-consuming task that leaves you vulnerable to typographical errors. To improve this process, you need to learn how to use the Catalog Data: Lookup function to search the catalog database for existing catalog numbers.

Tool Access In the Insert/Edit Component dialog box, under Catalog Data, click Lookup to select an existing part number from the part catalog.


■

219

Parts Catalog Dialog Box When you click Lookup, the Parts Catalog dialog box is displayed and you can access the database table that matches the family type of the inserted component. In this dialog box, you can search the database for a specific catalog item that you want to assign to the selected component.

220

■


Database Filters Database queries, or filters, appear in three lists across the top of the Parts Catalog dialog box. Query 1 is Manufacturer, Query 2 is Type, and Query 3 is Style. The Query 2 and 3 headings may vary depending on the component type you have selected. For example, when you select a motor component, the Query 3 heading is HP; when you select a light, the Query 3 heading is Voltage. Each time that you make a selection from one of the query lists, the catalog selection is filtered. As you make selections in the lists, the list of appropriate catalog numbers narrows.

Parts Catalog dialog box with all three filter lists displayed Main window of the Parts Catalog dialog box displays the identified matches

Selecting the All check box for a column removes the filter and displays all entries for that field from the catalog database. For example, the Manufacturer list can display all manufacturers for all part numbers that have been previously entered in the database table for the selected component family.


■

221

Parts Catalog Lookup Options The lower portion of the Parts Catalog dialog box has options for prefiltering, displaying, and editing the catalog database as well as the database and table selections.

Sorts the catalog entries by catalog number. By default the entries are shown in the order that they appear in the catalog database. Filters the symbol names using the WDBLKNAM value. If you select this option, records that contain a WDBLKNAM value that does not match the symbol block name do not appear in the catalog list. If you do not select this option, the query does not check the WDBLKNAM field and returns all catalog information matching the other selected sort criteria. The first character of the block name, called the orientation character, is removed. For example, a red light has a block name of HLT1R. If you select the Symbol Name Filtering option, only catalog entries with the WDBLKNAM of LT1R are displayed. If you set the option to OFF, all catalog entries in the LT table are displayed. Opens the Add Catalog Record dialog box and provides a template to add a new catalog item to the catalog database file. If you select a catalog number, the template is prefilled with values from the selected catalog number. Enables you to select the catalog record to edit from the Parts Catalog dialog box, and make any changes in the Edit Catalog Record dialog box.

222

■


Creating Parent-Child Relationships The basic process of selecting and inserting a child symbol, such as a switch or relay contact, is similar to the process used to insert a parent symbol. The process changes when you link the child to a parent component and enter the component attribute information. To establish the parent and child relationship, you need to understand the difference between the two insertion processes and how to establish the link between the parent and the child components.

Insert/Edit Child Component Dialog Box Except for the Component Tag area, the Insert/Edit Child Component dialog box is similar to the parent Insert/Edit Component dialog box.

The Catalog Data area is not displayed in this dialog box. Catalog data is stored in the parent component only.

Parent-Child Link To establish a parent-child relationship, the same tag value is used for both the parent and the child component. Differently named tag attributes on the parent and child components identify the symbols as a parent or a child. Under Component Tag, you find options that help you enter the matching tag value so that you can link the child component to its parent.


■

225

Use the following options under Component Tag to link the parent and child components. Option

Description

Tag

Manually enters the tag name of the parent component to be linked.

Drawing

Selects the parent symbol from a list of all parent symbols in the drawing. Only those parents of the same family type are displayed.

Project

Selects the parent symbol from a list of all parent symbols of the same family type in the project. Only those parents of the same family type are displayed.

Parent / Sibling

Selects the parent symbol or a sibling (child component) in the current drawing.

When the parent component is selected the tag value from the parent is copied to the child tag value linking the two together. Other attribute values from the parent symbol are also copied in the Insert/Edit Child Component dialog box. You can also edit the child attributes independently of the parent attributes.

226

■


Exercise: Insert a Relay Coil and Child Contact In this exercise you insert a limit switch, relay coil, and contact using the schematic symbol icon menu. You add information to the symbols using various copying and searching techniques to take advantage of existing data. You complete the following: ■ Insert a limit switch, copying description lines, and searching the project for catalog information. ■ Insert a relay coil, searching the drawing for catalog information. ■ Insert a relay contact and link the child contact to the parent coil.

Lesson: Inserting Schematic Components from Lesson: Lists This lesson describes how to create and use component lists to help you with your schematic drawings. You insert these listed components into your schematic drawings, linking the components between the schematic and panel drawings. Some workflows require a preliminary panel layout design to determine panel size requirements and to aid in ordering long lead time items early in the design process. Because both schematic-topanel and panel-to-schematic workflows are supported, you can start your design with the panel or schematic drawings. Use extracted component lists from either drawing set to add in components to the other. Virtually any workflow pattern is supported.


232

Describe the uses for and differences between equipment, panel, and catalog lists. Insert components into a schematic drawing using equipment, panel, and catalog lists for component selection.

■


About Equipment, Panel, and Catalog Lists At times you may want to limit your choices for inserting components. You may just want to use a list of components you have inserted from another project, or you may have customers who want only preapproved components used when you design and build their panels. To accomplish these tasks, you need to understand what lists are available and how to create them.

Definition of Equipment and Panel Lists An equipment list is a list of electrical components saved as an external file. You can use the project database, or you can create equipment lists by saving a report to an external file. The Insert Component (Equipment List) utility organizes the selected equipment list and presents it in a pick list. The Insert Component (Panel List) utility creates a list of all panel components by extracting the component information directly from the selected panel layout drawings. When using either an equipment list or a panel list, you select an item from the pick list and the utility uses the catalog number to search the schematic_lookup.mdb file for a matching schematic symbol. If a match is found, the symbol appears on your cursor and you are prompted for an insertion point in your drawing. If a match is not found you are prompted to select a symbol for insertion. The common tag name identifier automatically establishes a link between the schematic and panel components. Using this link, bidirectional updating is supported between schematic components and the associated footprint blocks. If you change a component, options are provided to update any related components in either the corresponding schematic or panel drawings.

Examples of equipment list files and file types

Lesson: Inserting Schematic Components from Lists

■

233

■

■

When selecting an equipment list, you can open a comma-delimited file, Microsoft Excel spreadsheet, or Microsoft Access database file for input. The Insert Component (Equipment List) utility does not account for quantity of components or duplicate insertions.

You can find the built-in editor for the schematic_lookup.mdb file under Miscellaneous Panel Tools. This process is the same as when you insert panel footprints from lists. For more information see Electrical Help Topics. Enter schematic_lookup.mdb in the Search tab.

Definition of Catalog List A catalog list is an external database file that contains a predefined list of schematic and panel symbols. You can select either schematic or panel components from the list, but only one type is displayed at a time depending on if you started the utility from the schematic or panel toolbars. The database file is in a generic Microsoft Access format and must be in the normal AutoCAD Electrical search path. You can add records to the list using Access or by using the Add and Edit buttons in the Schematic Component or Circuit dialog box. Block names are defined for each item in the list as it is added. To insert components from a catalog list, select the component from the list and then select the insertion point in your drawing.

Default catalog list

Example: Using an Equipment List You are creating a new design of a machine that you built for a customer a couple of months ago. They have requested some changes but want to use the same components used in the previous design. You create an equipment list by selecting the database from the previous project. When you select and insert items from the equipment list, you are assured of using only the components that were used on the previous design.

234

■


Example: Using a Panel List You work for a job-shop company that builds panels for your customers. Your customers depend on you for a fast turnaround of design projects. A new order comes in requiring the fastest design and build possible. You lay out the panel components, inserting longer lead-time items such as a variable frequency drive. When you have the correct sizing of the panel, you order all the long lead-time items. Next, you start the schematic design. You create an equipment list from the components you inserted in the panel layout. Selecting and inserting items from the equipment list, you get a quick start on the schematic design.

Example: Using a Catalog List One of your customers requires that only specified parts are used in their panels. The customer has supplied you with a catalog file of the approved components and footprints in MDB format. Instead of using the Catalog Data: Lookup function and searching through your company's entire parts database, you insert all components using the supplied catalog list.

Inserting Components from Lists When using an equipment list, you have to complete several steps. To execute the task efficiently, you need to know what the steps are and how to accomplish them.

Inserting Connectors Modern control panels are beginning to use connectors instead of individual connections more frequently as the preferred assembly practice. To efficiently insert these symbols, you need to learn about the different types of connectors, how to define their appearance, and how to inserted them in your drawings.

Connectors Defined Connectors are typically used to connect a wire or group of wires at a single junction. Unlike splices, connectors are designed to enable easy separation of the wires. Examples of each style are shown in the following illustrations. There are two different ways to insert connectors. You can insert the individual pins with parent and child symbols, or you can insert a single parametric connector that is built, spontaneously, based on information you enter or select.

Connector using parent and child symbols

Connector using single parametric symbol

Parent-Child Connectors The parent-child style of connector is inserted and has the same functionality as any other style of parent-child symbol. You must use the Insert Component icon menu to insert this style of connector. The individual symbols are inserted and associated together, thereby creating the parent-child relationship. The associated symbols act as a single component in reports and other functions.

254

■


Parametric Connectors The parametric style of connector has functions similarly to PLC parametric component insertion. With this style you can build the connector shape during the insertion process, changing pin spacing, breaking the component into separated pieces, and so on. The individual portions of the parametric connector are associated to the parent in a parent-child relationship.

Insert Connector Dialog Box and Options You use the Insert Connector dialog box to define the insertion of the connectors.

Defines the default spacing between pins for the new connector. Defines the quantity of pins to be included in the connector. You can edit the connector later and add more pins. Forces the connector to be created with the default pin spacing, or pins are automatically placed where the connector crosses a wire. If wire crossings are not found, the default pin spacing is used. Specifies the size of the connector. You select two points in the drawing for the size of the connector. The number of pins in the connector is determined by the selected size and the specified Pin Spacing value. Specifies that all pins are inserted without pausing for user input, or prompts you with the Custom Pin Spaces/Breaks dialog box after inserting each pin. Options in the dialog box include Insert Next Connection, Add Spacer, Break Symbol Now, and Cancel Custom. Inserts the connector as a child component. After insertion, you need to associate the connector with a parent component. Defines the starting pin number or letter. By default, the pin value increments by one character. You can enter a specific pin list order. Enter the pin values separated by a comma as in A,B,C,D, and so forth. If you insert a connector with six pins and enter 6,1,2 for the pin list, the connector starts at the top of the connector with pins 6, 1, 2, and then increments by one on the last number for the remainder of the required pins. Sets the orientation of the connector during insertion.

You can toggle the At Wire Crossing and Fixed Spacing options during the insertion process. Enter X and press ENTER to change the status.

256

■


Orientation Options The Orientation area contains controls for editing the connector direction. The Rotate and Flip buttons are used together to change the orientation of the connector. Using the Rotate (upper) and Flip (lower) buttons provides the following results.

Default only, no Rotate or Flip Connector Vertical, Plug Left

Default with Rotate only Connector Horizontal, Plug Down

Default with Flip only Connector Vertical, Plug Right

Flip with Rotate Connector Horizontal, Plug Top

You can change the orientation of the connector and the pin number order during the insertion process. Press TAB to cycle through the various options.

Describe the various types of terminals and jumpers. Describe multiple level terminals and jumpers, and how they are created. Insert terminals, establish associations creating multiple level terminals, and create jumpers.

Lesson: Terminals, Multiple Level Terminals, and Jumpers

■

271

About Terminals and Jumpers Terminals are one of the more frequently used and versatile types of components used in a schematic. They can be used to join multiple wires together at a single connection point, or they can act the same as a component, forcing a wire number change as the wire passes through it. Jumpers are used to join several of the same terminal numbers together instead of using wires, and can greatly simplify the wiring process. To effectively use terminals and jumpers in your schematics, you need to know what they are and the types or styles that are available.

Terminals Defined Terminals are one of several different kinds of components that you can use. Similar to a wire connection point on a standard type symbol, terminals are independent wire connection points that can be placed anywhere on wires. Depending on the style of terminal selected, they join several wires into one wire network or break a wire into two separate wire networks.

Example of a round terminal with wire connections

272

■


If you assign a Tag Strip value to the terminal, it becomes linked to a terminal strip along with all other terminals with the same Tag Strip value. The terminal strip displays the linked terminals in reports and panel layouts. You can think of each individual terminal as a subassembly component of the terminal strip.

Example of terminals assigned to the same terminal strip

Terminal Types You can choose from four different types of terminals. Each type is supplied in the following five different graphic styles or shapes: ■ Square ■ Round ■ Hexagon ■ Diamond ■ Triangle Terminal Type

Description This is a nonintelligent type. Only wire connection attributes are associated with it, and it does not appear in any reports. When you insert a terminal of this type, no Insert/Edit Terminal dialog box appears.


■

273

Terminal Type

Description This terminal takes on the wire number of the wire that is connected to, or passes through the terminal.

This terminal carries a user-defined terminal number assigned during insertion or editing of the terminal.

This terminal type forces a new wire number to generate as the wire passes through the terminal, in effect, creating a new wire network.

As with any other symbol, you can also create your own custom terminal symbols.

Terminal Jumpers Defined Terminal jumpers link two terminals together electronically into a single wire network. External jumpers link two physically different terminals together. No terminal levels or other block properties need to be set to create external jumpers between terminals. External jumpers are displayed in the Terminal Strip Editor grid as an empty circle. You can assign catalog number information to an external jumper, just like any other component. Internal jumpers link different levels of a multilevel terminal together. Internal jumpers are established during editing of the terminal block properties, or by setting internal jumpers in the terminal block properties table of the catalog database. Internal jumpers are displayed in the Terminal Strip Editor grid as a solid or filled square. In the schematic and panel drawings the physical representation of a jumper is not physically displayed by the software, that is, no block symbol is inserted in the drawings. Using the Terminal Strip Editor, jumper assignments can be displayed on the drawing in either a tabular terminal strip table or in a jumper chart.

274

■


Example of Using Terminals Within Schematic Drawings Terminals are frequently used when wiring enters or leaves a control panel. In this instance, a wire from a component in one panel is connected to a component in another panel. The wire runs from the first component to a terminal strip in the first cabinet. From there, another wire connects to the opposite side of the terminal and runs through a wire conduit to the second panel where it connects to a terminal strip. From the opposite side of the terminal the wire runs to the second component. On the schematic, the two components appear on a single line with the two terminals inserted between them. See the following image for an example. The relay contacts on the left are located in MCAB5 and have wires running to the terminal strip located in MCAB5. The terminals on the right are located on a terminal strip in OPSTA3 and have wires running to the lights, which are also located in OPSTA3.

About Multiple Level Terminals The density of terminals within panels is increasing with each passing year. To accommodate this, multiple level terminals are becoming more popular. To efficiently use this style of terminal, you need to know what they are and how to manage them.

Multiple Level Terminals Defined You create a terminal association between terminals to link individual terminal symbols into one multiple level terminal. In reports and on panel layouts the individual schematic terminals appear as a single item.


■

275

Example of multiple level terminals By default a terminal has the number of levels set to zero (0). To create associations between terminals or to set other block properties, a terminal must have at least one level assigned to it.

Terminal Block Properties Each terminal block can be assigned block properties that include the following: ■ Number of levels ■ Level Description ■ Wires Per Connection ■ Left Pin number ■ Right Pin number ■ Internal Jumpers Terminal block properties drive the behavior of the terminal in the multiple-level environment. For example, a terminal has the Wires Per Connection property set to two wires, but has three wires connected to one side. Automatically an additional terminal, with the same properties, will be created and inserted in the terminal strip to accommodate the extra wire. Block properties can be assigned to the terminal catalog number and referenced automatically when the catalog number is assigned to a symbol. You can edit the terminal block properties database table using the Terminal Properties Database Editor, which is found on the Components > Terminals menu. The tables are sorted by manufacturer.

276

■


You use Block Properties in the Insert/Edit Terminal Symbol dialog box to manually edit the terminal block properties of an individual terminal. Manual settings you make override settings from the terminal properties database table.

Internal jumpers are manually added by selecting two or more different levels and clicking the Assign Jumper button. Once an association is created between two terminals, you can also break it apart into two separate terminals. Both of the terminals are created with the same block properties as the original.

Use the Copy Block Properties command to copy block property settings between terminals on the same drawing. You start the command, select the Master block to copy the settings from, and select the terminals to copy the settings to.


■

277

Example of Using Multiple Level Terminals You are building a large panel that requires several hundred terminals, but space is becoming a problem for all of the panel components and the terminal strips. To help alleviate crowding, you replace all single level terminals with three level terminals. You create associations between terminals, thereby reducing the space requirements for the terminal strips by almost one-third.

About Circuits To better create your own custom circuits, it is helpful to understand what circuits are and how they are processed.

Definition of Circuits After a circuit is moved, copied, or inserted, the circuit is processed and the component tags and other information is updated where possible. To prevent duplication errors some data may be erased. A circuit is any collection of electrical objects that you manage as one group. A circuit may contain ladders, wires, components, or entire sections of your schematic drawing.

Example Circuits Your company uses several standard circuits in its machine schematics. Rather than re-creating the circuits each time they are required, you save the circuits as blocks, and insert them when needed. The following illustration shows a motor control circuit.

Guidelines Follow these guidelines when saving circuits to an icon menu. ■ The Save Circuit to Icon Menu and Insert Saved Circuit commands provide shortcuts to the User Circuits submenu in the icon menu system. You can also use the Insert Component command to achieve the same results. Select Insert Component > ...Schematic Symbols > Miscellaneous > User Circuits for circuit selection. ■ The Name field is displayed as the text in the icon with text and list views. Be very detailed when naming your circuit. This is an important step that enables you to identify your circuit when you want to insert it. The circuits are often too large and complicated to identify them clearly by using the icon alone. ■ When creating the icon from the current screen image, you must zoom in to the circuit you want to save. Try to make the view as large and as clean as possible, showing only graphics necessary to identify the circuit. ■ The advantage of the Save Circuit to Icon Menu command is that it provides a shortcut to the User Circuits menu. The disadvantage is that, because the circuits are automatically saved in the local User directory, they are not available to other users. To share a circuit saved in the User directory, you must copy or move the circuit to a shared folder.

Inserting Saved Circuits There are several ways to access the user circuits saved in the icon menu. To be most efficient, you can use shortcuts such as the Insert Saved Circuit command.

Lesson: Multiple Phase Circuits In this lesson you learn what three-phase circuits are and how to insert three-phase wires and components in your schematic drawings. The main power supply, especially for machine control designs, is usually in the form of a higher voltage three-phase power supply such as 460V.


328

Add multiple-phase ladders and wires to your schematic drawings. Add three-phase components to a multiple-phase circuit.

■


Adding Multiple-Phase Wires Three-phase circuits are typically represented in drawings as three parallel wires grouped together. Using the Add Wire command to insert three separate wires to represent the circuit is highly repetitive. To increase your efficiency, you need to learn how to use the Multiple Wire Bus tool.

Multiple Wire Bus Tool The Multiple Wire Bus tool creates wires that are AutoCAD line objects with wire layer assignments, just as the Insert Wire command does. You can use the Multiple Wire Bus tool to draw any number of bus wires at one time. Defaults of two, three, and four wires are provided for you. All of the wires are managed as a group during the insertion process. Wires are drawn parallel to one another, and even corners and connections are completed in a single operation. After the command is completed, the group of wires are separated into individual entities and edited and managed as separate wires.

Multiple Wire Bus

Ribbon: Schematic tab > Insert Wires/Wire Numbers panel > Multiple Bus

Menu Bar: Wires > Multiple Wire Bus Toolbar: ACE: Main Electrical > Insert Wire > Multiple Wire Bus

Procedure: Adding Multiple-Phase Wires The following steps describe how to add multiple-phase wires to your drawings.

330

1.

Start the Multiple Wire Bus command.

2.

In the Multiple Wire Bus dialog box, select your desired options, including the spacing, type of insertion, and number of wires.

■


3.

4.

5.

Draw unattached multiple-phase wires by selecting the start points and endpoints, similar to the Add Wire command.

Note: Selecting an endpoint ends the Wiring command. To connect to an existing bus, click the Another Bus (Multiple Wires) option.

To use the default phase sequence, select the start point on the bus farthest from the desired direction. For example, if you are drawing a vertical circuit from top to bottom, select the topmost horizontal bus.


■

331

332

6.

Slowly drag your cursor down over the other bus wires, connecting the new multiple-phase wires to the existing bus wires.

7.

To use the reverse the phase sequence, select the start point on the bus closest to the desired direction. For example, if you are drawing a vertical circuit from top to bottom, select the bottommost horizontal bus.

8.

Drag the cursor slowly across the other bus wires away from the desired direction, connecting new multiple wires to the buses.

■


9.

When all the wires are connected to the existing buses, drag your cursor back to the correct side of the bus for placement of the wires.

10. To lock or fix an endpoint but continue with the bus wiring, enter C at the Command prompt.

11. To reverse or flip the phase sequence of the wires when turning a corner, enter F at the Command prompt. The phase sequences are shown normal and flipped.


■

333

Adding Three-Phase Components Typically, components inserted on three-phase wires come in groups of three, one for each phase. To efficiently create this type of drawing, you need to learn what three-phase components are and how to insert them.

Three-phase circuit with multiple examples of three-phase components

334

■


Definition of Three-Phase Components Just like single-phase components, three-phase components are AutoCAD blocks with attributes. You insert three-phase components as a parent with two children. AutoCAD Electrical automatically inserts all of these components in a single operation, establishes the parent and child relationships, and creates the dashed link lines between the components.

Example of three-phase fuse

Procedure: Inserting Three-Phase Components The following steps describe how to insert a three-phase component. 1.

Select a three-phase component for insertion.

4.

Select a build direction. The symbols are inserted and connected with dashed link lines.

■


5.

Enter the component information in the Insert/Edit Component dialog box, as you would for a singlephase component.

When inserting a three-phase motor, select an insertion point on the middle rung of the three-phase power. Be sure to slightly overlap the rung endpoint. The threephase motor symbol automatically connects to all three rungs. If the three-phase motor insertion and wire connection does not work properly, make sure your drawing does not already have an older three-phase motor block definition. If it does, you can use the Swap/Update block command to redefine the existing block definition.


■

337

Exercise: Create a Three-Phase Circuit In this exercise, you create a complete three-phase circuit. You will be able to do the following: ■ Insert a three-phase ladder. ■ Insert three-phase wiring and fuses. ■ Insert motor starter, overloads, and motor.

Chapter Summary In this chapter you learned how to use schematic components in your drawings. Several methods are available to insert schematic components. When starting with an empty project, you use the Icon Menu system to select and insert the component symbols. When panel or schematic drawings exist, you can extract component lists to aid the insertion process. You can also use an external component list as an insertion tool. Some tools, such as the Circuit tools and the Multiple Wire Bus tool, provide intelligence and automation to otherwise repetitive tasks.
