Access platforms, Stairs and Ladders User Guide Introduction

1

Introduction This section introduces the AVEVA Access platforms, Stairs and Ladders (ASL) application. It identifies the different types of user who would need to read this guide and sets out what knowledge they will need before they start. The section provides an overview of the main functionality that the application introduces.

1.1

Intended Audience Users who are new to the ASL application should use this guide to understand the functionality of the application and the concepts employed by the system in the evaluation of the standards or 'engineering criteria' that the assemblies conform to.

1.2

Assumptions Users of the ASL must have read/write access to the project databases. It is assumed that:

1.2.1

•

The user has a basic knowledge of PDMS DESIGN.

•

The user is familiar with the basic graphical user interface (GUI) features as described in Getting Started with PDMS.

User Interface Workflow Each task panel has additional information relevant to that specific task the user and the application are currently engaged in, the concept being one of 'Progressive disclosure', i.e. not presenting the user with too much information on one form but simply presenting it in a more intuitive way that mirrors the work flow process associated with the creation or modification of that particular task.

Access platforms, Stairs and Ladders User Guide Getting Started

2

Getting Started This section explains how to get started with the ASL application. It describes the application to provide the DESIGN user with the necessary data to create assemblies in the 3D model.

2.1

Graphical Previews The application and all of the ASL assemblies provides a generic mechanism that allows the user to visualise and rationalise the net effect of the layout by modifying various attributes or sizes by generating a graphical preview of the changes prior to the user committing them to the database.

2.2

On Screen Dimensions A common tool, available on many ASL forms and task panels is the Measure icon:

This allows the fixed value or derived value assigned to the standard to be displayed in the graphical view and includes the attribute description as indicated on the forms; The detailed attributes are determined by their defaults, i.e. evaluated by the engineering criteria such that the value complies with the conditions or constraints defined against it, these conditions or constraints can include max/min, valid values, PML expressions, optimised values or real values. Each of the corresponding gadgets has tool tips to provide feedback to the user of the numerical range defined by the engineering criteria for that particular attribute. The direction attribute is not defined by the standard; this is a system default which is derived by the application via the positions of the principle work points.

2.3

Storage Areas Before any assembly geometry can be created a storage area should be assigned. To manage the setting of the storage areas, select Settings>ASL Storage Area from the menu toolbar to display the ASL Default Storage Area form. This form is used by the user for controlling where the system stores the standards and the instanced assemblies in the 3D model.

2.4

Creating Instances of Assemblies The functionality of the ASL application provides the means to quickly create, modify and verify the suitability of particular designs or layouts of rule based assemblies for the ASL elements. The ASL functionality is a sub application of the Structures application. To access ASL, select Design>Structures>Access, Stairs and Ladders from the main toolbar.

12.0


3.1.1

General Attributes The Create Stair Tower Definition form allows the user to set the general attributes, such as Name, Description, Function and Area. The form also identifies the tasks associated with the Stair Tower elements.

3.1.2

Direction and Location The application assumes that the Stair Tower direction is constrained to a rotation about the vertical axis for example N45E, W13S and the application will not allow the user to set a non vertical direction, in that event the application will issue an error message before resetting the format back to the default direction. The Pick Position link will activate the Positioning Control mechanism allowing the user to set the position with respect to any elements in the Design Database.

The positioning control task panel supports both the plant and ship grid (XYZ, ENU and Marine) co-ordinate system where the default position of the Stair Tower is positioning at the base elevation in the geometrical centre of the Stair Tower as indicated by the axes indicator. The default direction or the Stair Tower is north though this can be changed by the user.

3.1.3

Installation Sense The installation sense of the Stair Tower allows the rotation of the Stair Flights and Stair Landing to be rotated in either a Clockwise or Anti-Clockwise sense. When used in conjunction with Direction it allows the Stair Tower to be manipulated to suit the layout requirements for managing the various layouts of Flight direction and Landing orientation.

3.1.4

Select Configuration Type This toggle determines whether or not the application creates supporting steel for the Stair Tower.

If the Tower Steel Layout Configuration radio button is active, the application will create a network of beams and columns whose layout and spacing is derived by the layout of the Stair Flight and Stair Landing centres and the elevations of the Stair Landings Top of Steel or

3:2

12.0


Finished Floor Levels. The sizing of the Column and Beam profiles is set to a default specification reference though the user is free to select any profile type from the catalogue. If the Stair Landing Configuration radio button is active, the application will not create any supporting network of beams and columns, this scenario would exist where the Stair Flights pass through a Deck or Floor where the hole through which the Stair Flights pass has been engineered to accommodate the Stair Tower and Flights.

3.1.5

Perform Task Select Create Stair Tower Element to commit the changes made on this form to the database and take the user to the Create Tower Steel Layout Definition form. Selecting Back to Main Task will not commit these changes to the database and will take the user back to the Main Stair Tower Tasks form.

3.1.6

Create Tower Steel Layout Definition The Create Tower Steel Layout Definition form is responsible for managing the sizing and positioning of Stair Landing elevations.

3:3

12.0


A graphical representation or preview in the 3D canvas of the Stair Tower reflecting the information in the form which can be modified by the user to suit the layout of the adjacent model data to which the Stair Tower is being defined. The graphical preview is based on the engineering criteria defined in the 'ASL standards' and these values will be written to the appropriate attributes of the Stair Tower. To minimise the degree of post creation modification the Stair Tower functionality provides a graphical preview prior to the creation of the detailed representation of the final design, this workflow has been adopted to enable the user to modify the Stair Tower as required by changing specific dimensions, directions or selections, and can also include the creation of additional entry or exit points as maybe required by adjacent model data or access requirements. The form and the graphical preview indicated above shows how the dimensions from the actual engineering criteria defined by the relevant standard have been used to give a realistic geometric preview of the Stair Tower, the graphical representation indicates; •

The Position and orientation of the Stair Tower

•

The overall size (Xlength, Ylength and Height) of the Stair Tower

•

The number off and elevations of the supporting Beams

3:4

12.0


The form also demonstrates the concept of 'progressive disclosure' of the information and data that has been applied by both the user and by the system from the current standard to the attributes of the Stair Tower. The tasks associated with the creation and modification of the Stair Tower have been grouped into collapsible 'task' panels to minimise the amount of information visible at any time. The form layout also simplifies the workflow by grouping the tasks by specific actions; the following headings will describe in more detail the function of the task panes.

3.1.7

Tower Layout Attributes The overall sizing of the Stair Tower is not controlled by the engineering criteria, these properties are user definable and can be edited by the user which are then previewed graphically on the screen.

3.1.8

Column SPEC details The Column Profile and Column Justification fields have preset values, these can be changed to any other profiles reference using the Section Profile Selection form. Select the Select SPEC for Column link to display the Section Profile Selection form.

3.2

Create Stair Landing Layout Definition The Create Stair Landing Layout Definition form is responsible for managing the layout and detail definition of the Stair Landings.

A graphical preview of the Stair Landings is presented to the user showing the layout of the Stair Landing and Handrailing and also indicates: •

The Stair Flight and Stair Landing centreline distances

•

The Stair Landing configuration and rotation sense

•

The Stair Landing elevations

The main functions of the tasks shown on this form are described below.

3:6

12.0


3.2.1

Stair Landing Installation Details Landing Configuration This option allows the user to visualise the different installation scenarios for Stair Landings and associated Stair Flights prior to committing the installation to the database. As each configuration is selected the graphical preview is updated to reflect the change. Landing Attributes The Stair Landing attributes manage the sizing of the Stair Landing which can be edited and previewed graphically. The Stair Landing Thickness is managed by the value defined in the current Standard and is subject to the checking mechanism of the min/max criteria such that if the user attempts to input a value that exceeds the criteria the system will provide appropriate feedback. Tower Layout Details The values populated in the Tower Layout Details are values that are managed by the current Standard or they have been derived as a result of the Stair Tower layout such as the Tower (X and Y) length attributes.

3.2.2

Catalogue and Assembly Details The user must select the Assembly data for Stair Flights, Stair Landings and Handrails to define the Stair Tower. This mechanism provides the maximum flexibility in that the user and the system are not constrained to individual Standards referencing individual Assemblies.

Tie-Up Beam Selection Details This defines the 'Tie-up' beam that was not part of the previous elevation beam data and is coincident with the Landing Length supporting the unsupported span of the Stair Landing.

3:7

12.0


The default profile is as indicated in the form below though the user can specify a different profile and justification. Stair Landing Assembly Selection There are a number of different Stair Landing Assemblies in the AVEVA supplied standard data for ASL, these are located in the following Application Data World (APPLDW) hierarchy and can be selected using the Stair Landing gadget above, provided that is that the Administrator has added them to the users 'ASL selection'.

Handrail Assembly Selection The Handrail are also located in the APPLDW and can be selected using the Handrail gadget. This will update the graphical preview with the appropriate graphic. Perform Task Select Create Stair Landings to commit the changes made on this form to the database and take the user to the Create Stair Flight Layout Definition form. Select Back to Tower Steel Definition to take the user back to the Create Tower Steel Definition form. Selecting Back to Main Task will not commit these changes to the database and will take the user back to the Main Stair Tower Tasks form.

4.1.1

General Attributes The Create Stair Flight form allows the user to set the general attributes, such as Name, Description, Function, Purpose and Area. The form also identifies the tasks associated with the Stair Flight elements.

4.1.2

Installation Options The four installation types, Straight, L-Shaped, S-Shaped and U-Shaped address the majority of the installation scenarios for Stair Flights. If an installation option has not been set and the user has defined the Lower and Upper work points, the application will prompt the user to select an installation option against which the evaluation will be based. The Left/Right Option becomes active if either the L-Shaped or U-Shaped installation option is selected. On selecting the Left Option the subsequent Flight turns left from the Previous one.

4.1.3

Position and Direction The Position and Direction task panel provides both graphically interactive and explicit methods for positioning the lower and upper work points that define the Stair Flight, as shown in the diagram above the origin of the Stair Flight is coincident with the intersection of the Lower WP and the plane of the lower pick at the midpoint between the Stringers. Selecting either the Lower or Upper Position link will activate the Positioning Control mechanism for graphical selection of the work points and population of the position gadgets in the form.

Explicit positioning either via the Upper or Lower WP is supported and the system will check the results of the new position against the engineering criteria of the Stair Flight to the criteria of the current specification and if valid the Stair Flight will be re-positioned. The default Flight Direction or the Stair Tower is north though once the Stair Flight has been created it is set by the application based on the positions of the lower and upper work points. Having input the Upper Work Point position using either the explicit of graphical method and the position gadget has been populated the Lower Work Point Position gadget becomes active.

4:2

12.0


Selecting the Plane toggle changes the options displayed to the user for selecting the Lower Working Point. The user can now specify a plane and direction onto which the Upper Work Point will be projected.

The selected position value is used to position either the landing or the landing stringer TOS, based on the selection made in FFL/TOS. Landing is either Flushed or placed above the Landing Stringer based on the selection made in Flush with Landing / Above Landing. The same applies for the Upper Work Point as well. Both these landings and the intermediate landings if any will be of thickness provided in the Landing thickness. The U-Flight Offset is the distance till which the U-Type Stair Flight extends along the Normal direction between the picked points. If the user does not click Pick position for the distance or enters a value then the Offset value is derived using optimum values.

4.1.4

Modify Leg Going The Stair flight Leg Going form is displayed when the Lower Extension, Upper Extension, Lower Landing Length or Upper Landing Length linklabels in Stair Flight Detail Attributes form are clicked.

4:3

12.0


To update the change the calculated Length after modification should be the same as the Actual Length along that direction at before modification.

4.1.5

Assemblies The Assemblies task panel identifies the Stair Flight assembly data being used to create the instances in the design model. The current standard to which the Stair Flight assembly is being evaluated against is indicated in the main menu bar. Select Stair Flight Detail Attributes to display the Stair Flight Detail Attributes form, which stores both the criteria from the standard such as Width and Headroom for example, and the evaluated criteria based on the positions of the work points. These attributes appear greyed out and therefore are not modifiable as they have been evaluated and validated by the system and subsequent manual overrides could easily invalidate the assembly.

4:4

12.0


In the example shown above the Stair Flight actually consists of two flight segments as the system has determined that one flight does not meet the satisfactory validation of the criteria and therefore required two flight segments with the insertion of an Intermediate Landing. The Intermediate Landing by default is positioned at the midpoint between the lower and upper work points, the user can toggle between the two Flight segments which will refresh the attribute gadgets below. The Upper Elevation gadget stores the elevation of the Intermediate Landing element, this is a transition element between the Flight Segments, the requirement for an Intermediate Landing and is determined by the system evaluation of the criteria. The Pick option to the right of this gadget allows the user to modify the position of the Intermediate landing and subject to the validity of the criteria the Stair Flight and the Flight Segments will be modified to suit. The new elevation can be manually input or graphically selected using the position control object.

4:5

12.0


4.1.6

Perform Task Evaluate Stair Flight Select Evaluate Stair Flight to check the validity of the Stair Flight against the criteria defined in the current Standard, if the Stair Flight assembly is valid the system will display a graphical representation of the Stair Flight showing both the lower and upper work points and the number of Flight segments associated with the Stair Flight. The system provides additional checking and will not allow the lower and upper work points to be on the same elevation, where there are positional irregularities the system will provide appropriate feedback before performing a check against the criteria.

Create Stair Flight When the user is satisfied with the layout of the Stair Flight and the system has validated the criteria, the Stair Flight can be created and the detail representation of the Stair Flight and Handrail will be that previously defined in the Assemblies task.

Create Ladder Form From the main toolbar, select Create>Ladder to display the Create Ladder form. The system behaviour for the evaluation starts when the user defines the lower and upper work points using either the explicit or graphical positioning mechanism, the system then determines the vertical distance (Overall Rise) between these two graphical positions and checks and validates the results against the engineering criteria of the Ladder to the criteria of the current Standard. If the system analysis validates the values against the engineering criteria the system will create the Ladder and populate the attributes with the appropriate data.

5:1

5.1.1

General Attributes The Create Ladder form allows the user to set the general attributes, such as Name, Function, Area and Number. The form also identifies the tasks associated with the creation of the Ladder.

5.1.2

Position and Direction The position and origin of the Ladder is located at the bottom of the ladder midway between the Ladder Rungs and has pseudo attributes defining the position of the lower and upper work points. Position The Lower Work Points and Upper Work Points links will activate the Positioning Control mechanism allowing the user to set the position with respect to any elements in the Design Db and the positioning control task panel supports both the plant and ship grid (XYZ, ENU and Marine) co-ordinate system. The Plane option also provides the ability to identify a plane onto which the Upper work Point will be projected which is determined by the pitch of the Ladder. The default direction or the Ladder is north though this can be changed by the user.

Direction The default direction of the Ladder is set to North though this can be modified by the user to rotate the Ladder around its vertical axis.

5.1.3

Installation and Assembly Options The Installation options for the Ladder are defined by the exit location at the top of the Ladder, the exit direction has a direct influence on the design and layout of the cage (where one has been deemed necessary by the evaluation of the Ladders height). The application and the Assembly data allow for four kinds of exit direction; Front, Back, Left and Right. The convention of Left and Right is where the user is standing at the base of the Ladder, facing it as if to climb the ladder. Depending on the type of exit type selected this will adjust by extending or reducing the length of the Ladder Stringers and the number of Ladder Rungs to suit.

5:2

5.1.4

Evaluate Ladder Link Once the Lower and Upper Work Points have been defined the Evaluate Ladder will preview the graphical representation of the Ladder so the user can visualise the layout of the Ladder and can view the resultant 'Detailed Attributes' below. Detailed Attributes These attribute values represent the engineering criteria defined in the standard and are evaluated based on an upper and lower or max/min allowable values defined by the Administrator. Once the Ladder definition has been evaluated and validated by the system the attributes for the Ladder are populated in the detailed attributes form shown below.

5.1.5

uses the Pick position to graphically pick a position or edits the elevation directly in the forms grid object. If the user edits the explicit position within the form grid object the Pick position and Delete selected will become un-highlighted.

5.1.8

Pick Position Pick position allows the user to enter the graphical selection mode and using the positioning control and graphically pick an elevation defining the Upping component or elevation of the Ladder Exit. The system will re-evaluate the design based on the changes and if the changes conform to the engineering criteria defined in the standard the system will commit the changes to the Ladder Exit, Cage Segment and Ladder and will create an Entry/Exit location in the Ladder with a clearance Headroom of 2200mm as defined in the engineering criteria.

5.1.9

Delete Selected This allows the user to delete the selected Ladder Exit, upon deleting the Ladder Exit from the Ladder the system will re-evaluate the standard or engineering criteria and update the graphical view.

5.1.10

Create Handrail Form The Handrail functionality of the ASL application provides the means to create and assess the suitability of particular designs or layouts of Handrail assemblies and is a useful design tool in the initial laying out and detail design phases of a project. From the main toolbar, select Create>Handrail to display the Create Handrail form.

The Create Handrail form takes the user straight into the boundary definition task associated with tracing the path of the Handrail, for the purposes of documentation select the Back to main Handrail tasks to present the Main Handrail Tasks form.

7:2

12.0


The Create Handrail form allows the user to decide which data to use, either the Default representation which is a core based representation requiring no detail geometry or an accurate detail representation which is held in the ASL Application Data World. The advantage of the Default representation is that there is no delay in defining a conceptual layout for Handrailing as there is no catalogue or Assembly data requirements. The Post data describes the layout and spacing of the Handrail Post elements, this data is part of the standard or engineering criteria that is evaluated when Handrail assemblies are created or modified. The system will not allow these values to fall outside the range of the max/min of the values stored in the standard for that attribute; attempts to change these values beyond the criteria will prompt the system to return an error message reminding the user of the allowable ranges. The Rail data settings allow the user to modify the number of Rails and their spacing using the Spacings grid, this only applies to the default representation as the Detail representation is determined by the ASL standard. See more detailed descriptions below All the graphical feedback is presented on screen using graphical aids so the user can layout the information and have a real time preview of the resultant geometry prior to committing the changes to the database. The user can also be certain that the engineering criteria of the graphical preview have been validated by the system.

7.1.1

Rail Spacing The option to Add, Remove or Modify the elevations of the existing Rails only becomes active when the Template option at the top of the form is set to Default, the Default

7:3

12.0


representation can be used during the conceptual stages of the project before the fabrication details for the Handrailing is known, or simply for visualisation purposes. If the default representation is used the user can at any time change the representation back to the Detail representation as per the Default, project or User standards defined in the Application Data World. The appropriate spacings for Rails rail should be highlighted in the grid object and the 'Use', option saves this as the current rail spacing selection, the spacing attribute or dimensions shown in the form grid object is referenced from the zero datum.

The Default representation of Handrail is still evaluated against the Standard or engineering criteria defined in the Standard and any user modifications are automatically validated by the rule checking engine and appropriate feedback is returned to the user. Inputting data that exceeds the criteria will result in an error message.

7.2

Handrail Geometry The Handrail Geometry form provides the functionality for creating the boundary in a variety of ways including free form graphical sketching or by tracing existing boundary elements.

7.2.1

Copy Path of Owner For a faster and more efficient means of defining a Handrail certain boundary elements defined using a Routing Path have their boundaries copied directly by the system to define an open or closed boundary of the Handrail. The Copy Path of Owner link will present a

7:5

12.0


graphical preview of the Handrail, this might be used when tracing the boundary of the owning Platform, the preview will number the vertexes and the system will prompt the user to graphically select a vertex to define the start and end. This provides a quick means to exclude certain facets of the Handrail as indicated below; alternatively the Closed option will close the boundary.

The system prompt requesting the user to define the Start/End positions of Vertex 1 for the Start and Vertex 6 for the End will define the following path shown on the left; the Close option is shown on the right.

Once the graphical preview has been displayed the link for modifying the Handrail geometry become active, these provide the user with the functionality to highlight the individual vertex's and perform the specific actions.

7.2.2

Copy Path of Picked Item Similar in concept to the Copy Path of Owner, this allows the user to trace the path of a picked item, typically this might be a Panel element.

7:6

7.2.3

Insert Corner/Segment Link The Insert Corner/Segment functionality provides the user with the ability to free form sketch the path or boundary (using the close option) of the Handrail using the graphics of the 3D view. The system prompts the user in the status bar to graphically pick vertexes or edges along which the route will updates with each new selection. If the 'Closed' toggle is checked the system will display the graphics in terms of a boundary definition, unchecked displays a path definition. The 'escape' key will exit from the free form sketching functionality and the system will activate the modification options if any further editing of the path or boundary is required. To save the route definition to the database, select the Accept Changes link followed by the Back to Create Handrail link to Create Handrail.

7.2.4

Set Current Vertex Link Where the user wishes to select a vertex to modify selecting the Set Current Vertex link will graphically highlight the numbers and position of all the vertexes and the system will prompt the user in the Status bar to Pick VERTEX to be made current: When the user identifies the new vertex the system will update the graphical preview to show the 'Current Vertex'. The user can now perform any of the modify operations.

7.2.5

Move Current Vertex Link Selecting this link will graphically highlight the position on the Handrail of the current vertex and the system will prompt the user in the Status bar to Pick position the vertex to be moved to: When the user identifies the new position the system will update the graphical preview of the handrail for the user to accept or discard the changes.

7.2.6

Remove Current Vertex Link Picking this link will remove the current vertex and graphically highlight the new path of the Handrail which will draw the new path which start and ends at the vertex position before and after the vertex that has been removed. The system then updates the graphical preview of the handrail for the user to accept or discard the changes.

7.2.7

Remove Picked Vertices The Remove Picked Vertices link once selected, displays a prompt to Pick start VERTEX of sequence to be deleted: and once the vertices to be deleted have been selected the system presents a confirmation message to the user for them to confirm the option of deletion. Where the conformation is accepted and the Accept Changes' has been selected the system will remove the graphical preview of the handrail and commit any changes to the database.

7.2.8

Remove all Vertices The Remove all Vertices link will highlight all the vertices in the handrail definition and present a confirmation message OK to remove all handrail vertices, accepting this option and Accept Changes will delete the Handrail from the database.

7.2.9

Extend Start/End This link will highlight the vertices at the start and end of the Handrail with a Start and End on screen graphic and prompt the user to Pick handrail end to be extended and once identified will prompt the user to identify a new position for the vertex

7.2.10

Shift Offset This link is an 'In/Out' button that repositions the Kick Plate (where one has been used in the Handrail definition) to the Inside or Outside of the Handrail Post. The layout of the Handrail will then be updated to suit.

7.2.11

Gates Link The functionality to create Handrail Gates can be displayed from this location on the Create Handrail form as indicated in the image above or from the Main Handrail Tasks form also indicated above. Either call for this functionality will call the same form as indicated and described below.

Gates

7.3.1

Add Gate Link Adding an access opening to a Handrail element using the functionality in the form below will create the Handrail offspring of Handrail Feature for the ownership and management of Handrail Gate elements of which there can be multiple Handrail Gate elements per Handrail Feature. Populating the form grid object with the Handrail Gate data is done using the Add Gate link, once picked the system will prompt the user to 'Pick position to insert GATE:' as indicated below. A graphical indication on the Handrail element will derive a position along the Handrail path and a graphical preview of the position and size will be displayed along with a numerical identifier corresponding to the number of Handrail Gate's in the Platform Feature. The X/Y position of the Handrail Gate is derived by the system from the path of the Routing Path element, the Handrail Gate origin is at the centre of the opening and coincident with the Platform elevation. The data for 'Width' in the form grid object is the default size for the 'Width' attribute and can be modified directly in the form grid by highlighting and editing in place. Accepting the changes will commit the changes to the database and the system will update the graphics after first resolving the post spacing due to the addition of the Handrail Gate opening.

7:9

7.3.2

Position Gate Link The position of the Handrail Gate can be modified interactively with graphical picks. Picking thePosition Gate link will generate a system prompt to the user to 'Pick position of GATE to be moved to:'. The graphical pick will present a graphical preview of the new position and accepting the changes will commit the changes to the database and the system will update the graphics and resolve the post spacing due to the modification of the Handrail Gate. To exit from the position gate prompt without graphically highlighting a new position can be interrupted by pressing the Escape key.

7:10

Access platforms, Stairs and Ladders User Guide Handrail Assembly Rules

8

Handrail Assembly Rules The handrail assembly template exists as HANDRA item below APPLDATA hierarchy. Two basic types are recognised by the application, regular (non-panelised) and panelised.

8.1

Regular Handrail If the assembly contains post (HRPOST) elements and any number of RAILs, it is treated by the application as a regular "non-panelised" handrail. Optionally it can contain kick plates (KICKPL) or in-fill panels (HRPANE).

8.2

Panelised Handrail If the assembly contains panels (HRPANE) and does not contain any post or rail then it is recognised as "panelised". Optionally it can contain kick plates.

8.3

Basic Principles The assembly (HANDRA) is not copied to design instance as a whole, each handrail member (HRPOST, RAIL, KICKPL, HRTERM, HRPANE) is created as a copy of the item from the assembly. The reference from the design instance of handrail to the assembly template is established via attribute ASSTMP. Each handrail member has the same reference to the item it has been copied from. All members can have XOFFset value set. If the value is positive it is assumed that the offset will be made away from the imaginary shape formed by handrail boundary/path (e.g. edge mounted post).

8:1

12.0


If the value is negative then the offset is made inside (e.g. floor mounted post). If the imaginary shape is anti-clockwise the offset value is shifted (multiplied by -1) by the application in order to keep the actual offset.

Positive offset (edge mounted post)

8.4

Negative offset (floor mounted post)

Posts (HRPOST) The first HRPOST below the handrail assembly is used as a template for all posts within the design instance of handrail, the others, if any are ignored. The post is placed along the RPATH by setting the ZDIStance and position reference to POINTR where the zdistance is measured from. So the HRPOST should be constructed symmetrically along its Z-axis and the lower end of post should be at its origin. If the offset is needed then ZOFFset or XOFFset of HRPOST can be specified. The application does not modify the offsprings of HRPOST directly, it only sets principle attributes of HRPOST and then evaluates the attribute rules. The attributes of HRPOST that are set by the application: POSREF ZDIS XOFF (only the sign can be changed while the absolute value is kept). All other attributes keep their initial value as specified in the assembly.

8.5

Rails There can be any number of rails within the template assembly and all of them will be copied to design instance. Each rail is defined by a start and end position reference to POINTR within RPATH and its elevation (ZOFF) measured from associated segment of RPATH. The RAIL element has no members, its physical shape is defined by specification reference (SPREF) to catalogue profile. The offset of RAIL is handled by the same way as HRPOST.

8:2

12.0


The attributes of RAIL that are set by the application: STAREF ENDREF XOFF (conditionally shifted only) All other attributes keep their initial value.

8.6

Kick Plates (KICKPL) Definition of kick plate is similar to rails. The first KICKPL within the assembly is relevant and will be copied to all design instances of kick plate below handrail. The KICKPL will be made only on horizontally running segments of handrail. The same principles are applied to offset. Justification of KICKPL should be set to p-line that is in the middle of bottom side of the profile (e.g. BOS). The offset justification (e.g. LBOS or RBOS) will not be shifted by the application. The attributes of KICKPL that are set by the application: STAREF ENDREF XOFF (conditionally shifted only) All other attributes keep their initial value

8.7

Handrail Termination (HRTERM) Basic definition HRTERM is similar to HRPOST in some aspects. It has reference to POINTR (POSREF) and ZDIStance. The HRTERM can be placed to the end and/or start of the handrail that is not closed. The HRTERM on handrail start has POSREF set to first POINTR of handrail RPATH while ZDIS is set to zero. HRTERM on handrail end has POSREF set to POINTR next to the last and ZDIS is set to length of last segment so that its position is the same as position of last POINTR of RPATH. The application does not alter the offsprings of HRTERM directly, it only sets principle attributes of HRTERM and evaluates rules. The origin of HRTERM should be as depicted below. To enable skewed HRTERM (e.g. termination of handrail along stairs) the application computes and set the value of attribute ANGLE that should be deployed within attribute rule definitions of HRTERM members. Similarly the BANGLE attribute (rotation about Z-axis) should be used to enable rotation of HRTERM as it does not have attribute ORI. All its members should have the rule for attribute ORI reflecting the current value of BANGLE. The application automatically sets its value to 180 degrees when HRTERM is placed at the start, otherwise it is set to zero. The array attribute RAILTRIM is used by application to trim the matching adjacent RAILS counted from below. If the attribute is not set then no RAIL will be trimmed.

8:3

12.0


The offset is handled by usual way.

The attributes of HRTERM that are set by the application: POSREF ZDIS ANGLE (sloping angle - zero if adjacent segment is running horizontally) BANGLE (to flip HRTERM at start) XOFF (conditionally shifted) All other attributes keep their original value.

8.8

Panels (HRPANE) of Panelised Handrail HRPANE is positioned along RPATH using position reference to POINTR and ZDIStance measured from that POINTR. The length of HRPANE is expected to be defined using value of attribute PANESIZE[1] along Y axis of local coordinate system (as depicted below). The value of PANESIZE[1] will be set by application for every instance o panel. The height definition using PANESIZE[2] is not obligatory but it is recommended. The value of PANESIZE[2] is not altered by the application.

8:4

12.0


The skewing of HRPANE should be enabled using attribute RISE (see below) which is set by application. Note: The length calculated by the application is always the actual length of HRPANE, not the length projected onto horizontal plane.

When HRPANE is placed at curved segment edge, its local Y axis is aligned tangentially to the curve by default. The application calculates and sets the attribute BANGLE so that the other end of HRPANE matches the curved segment. As it does not have attribute ORI it cannot be rotated explicitly so all members of HRPANE (e.g. GENSECs) should have rule for attribute ORI to enable the rotation.

8:5

12.0


It is expected by the application that HRPANE has defined its minimum/maximum length as well as the default value. It should be held within DDSE element (below HRPANE) as DDAT element. The following attributes have to be set: PURP DFLT DKEY LENG PTYP DIST DDDF

MAXMIN[1] MAXMIN[2] There can be any number of HRPANE below single assembly with different max/min definition assuming the lengths are connected. The application will then select the best fitting panel for every instance. The max/min definition is not copied to design instance and it is always extracted from the assembly via ASSTMP reference attribute. If no max/min length definition is found below HRPANE then it is treated as fixed length and the length is taken from value of PANESIZE[1] of assembly. If the value is not set the HRPANE is ignored by the application.

8.9

Panels (HRPANE) of Non-panelised Handrail HRPANEls can be used to fill the gap between posts and rails. They are placed to straight segments only. The same principles are applied as mentioned above. In this case the concept of max/min definition is not used; the application will calculate and set the value as distance between two posts. The number of such panels within assembly should correspond to number of rails. Also the value of their ZOFFset and height (PANESIZE[2]) should correspond to ZOFFset of rails. List of attributes of HRPANE that are set by the application: POSREF ZDIS PANESIZE[1] (length of panel) RISE BANGLE (for panelised handrails only)
