Creating a project

3.1

Program start

You can start AVEVA Bocad in two different ways: 

- Double-click the AVEVA BOCAD icon on your desktop



- Select the correspondent entry from the Windows Start menu. Both procedures will start AVEVA Bocad and two windows will open successively. First a DOSWindow will appear, from which the AVEVA Bocad program will be launched. The DOS window is automatically shown in the task bar. It should not be closed whilst working with AVEVA Bocad because that will close the program immediately without saving.

Once AVEVA Bocad is started, the program shows a license dialogue that can be closed with the OK button.


12


3.2

File: New / Open

Creating a new project A new project must be created before starting the design process. To do this, open the File menu from the menu bar. From the File menu, select New ... A new dialogue will open where the name of the project can be entered.

(1) Displays the project directory, if required you can use the New button to overwrite a selected existing project or the Delete button to remove projects. (2) Existing project-related drawings are displayed in the Preview window. (3) Displays project data for the selected project. (4) Input field for the project name.

3.3

Rules concerning directory names

To create a new project you have to enter a name into the input field below the project directory. 



Project names are composed only of small letters (capital letters are automatically transformed). Special signs, such as ' ! " § $ % & / ( ) = ' as well as language specific special signs are not allowed and will be rejected.



Numbers may be used.



Spaces are not possible in project names; whereas single words can be connected by


'_' (underline).

13


Examples for permissible names

Examples for not permitted names

small_hall

Extension of a STEELHALL (no use of underlines)

roof_2004

canopy_(1265) (use of special characters)

After confirming the new file name by pressing the button OK, a file for the new project will be created below the project directory ([installation drive]:\bocad\project). All data concerning the project will be stored in that directory. The data includes e.g. all created members, drawings, parts lists and project-related settings carried out in AVEVA Bocad.

3.4

Input of project data

After establishing a new project you can determine more details. These details are always available in the current project and can e.g. be evaluated for the parts lists or the drawing generation. The dialogue Start new project has two different input areas: the area above is for the input of project data; the area below is for the definition of a basic grid (you will find more details about that later): (1) Entry area for project data. (2) Entry area for the basic grid. (3) Visualization of the basic grid with activated preview.

Click on the tab More in order to show those entries for extended project data:


14


Now you can set more entries. Theses entries can be modified later with the Project data function from the Structure menu.

Here, no rules must be observed (as during the determination of the project name). In order to make an entry you have to click into the according line with the mouse (take care to remove the pre-set hyphen, else it will reappear later). After entering the project data, a dialogue is opened where the main view is defined by which the project will now be started.


15

CHAPTER 4

Handling of AVEVA Bocad

4.1

User interface

The program surface consists of the main window with the menu, icon and status bar and the working area. Here you can open and arrange (member) views for your project processing in subordinate windows.

(1) (2) (3) (4)

Title bar of the main window Main menu Standard area for icon bars Working area

4.1.1

(5) (6) (7) (8)

Status line Trace window (here minimised) View window View window with basic diametrical perspective

Menu bar

The main menu is below the title bar of the main window and contains all processing functions of the program (arranged according to subjects).

Click a menu point in order to open the required pull-down menu.


16


4.1.2

Pull-down menus

In the individual pull-down menus of AVEVA Bocad you will find the functions of a selected menu. By clicking on the relevant entries you will start the required program function.

4.1.3

Status line

The status line is at the bottom of the program window and subdivided into five horizontal areas. The individual areas inform you about:

(1) Input status. Similar to a traffic light it shows you whether a program input is currently possible or not (e.g. during longer calculations or a security query).

Left: entry poss ible. R ig ht: prog ram is busy. (2) Message line. After selecting a function from the menu you are guided through each of the next operating steps to be done.

(4) Currently selected pick mode.

 The pick mode is explained in section 'Handling of AVEVA Bocad: pick mode'. (5) Current phase. Here you see the phase plane you are working in. As long as you do not create a new phase, all design steps refer to Phase 1: des ig n step.

 See section 'Phases' for further information.

(3) Currently selected working or design step.

4.1.4

Trace window

A separate window of the working area opens automatically when starting the program and shows the Message information in which you can find indications and possible error messages. In the first line of the trace window you will also find the revision number after starting the program. This Trace window has the same functions as the views windows but can, however, not be closed.


17


4.2

Icon bars

All important functions of AVEVA Bocad can not only be accessed via the menus but as well via categorised symbol bars. Since in real working conditions all existing symbol bars are never required at the same time and the simultaneous representation of some hundred individual symbols would be extremely confusing -, the necessary functions can be determined individually, depending on working condition and habit. Toggles in front of the entries indicate that the icon bar is already activated, i.e. it has already been placed. Via Line up you can arrange the icon bars automatically. By clicking this entry all activated icon bars will be summarized forward or upward, i.e. in a place-saving way.

Example: Activate icon bar 





Place the mouse cursor on an icon bar. Click the right mouse button in order to open the context menu (see right side). Select a menu entry, e.g. plane .

Result The context menu will be closed and the chosen icon bar will be automatically registered above. You can also remove the bar and place it individually anywhere in the working area. If you have once activated a window and placed it on a certain spot it will be placed at the same position again on its reactivation. If you open the context menu again (as explained before) you will see a toggle in front of the menu entry of the selected and visible icon bar. That toggle indicates that the relevant bar is activated and visible on the screen.

4.3

Pick mode

The pick mode allows the easy and direct selection of elements which are very close together. The correct selection of the pick mode makes it possible to work precisely and to avoid unintentional entries. The activated pick mode will always shown in the following table. be displayed in the Status line and permits only the marking of the elements


18


Members : catches member edges.

Plots-lines: catches graphic elements.

Bolts: catches all connections except pop marks, welds and structural connections.

Weldings: catches only weld seams.

Member, bolts and points

Random: catches any element types.

Points: catches grid, pick and database points.

Free: enables free marking without reference to elements.

Text: catches any texts as e.g. designations of axes.

Selection window : opens a window where additional pick modes can be selected.

Dimensioning: catches all dimensioning elements. For many functions, the selection of an adequate pick mode is a significant working step. If e.g. the Delete a member function requires the selection of a member and the pick mode is set on pick points, no member can be selected; and the function can only be terminated when an adequate pick mode is selected. A significant characteristic of the pick mode is the function-related validity. When the pick mode is changed this is valid for the current processing step of the currently active function. Thus the pick mode will not be maintained until the next manual modification but will be switched into the latest modus or into a reasonable default modus for every function and every working step. They adjust themselves to the individual working processes and thus support in particular repeated design steps. Behaviour of pick mode concerning function and working step Execution of the Split member function First usage of function Members (Indication in case of this function)

4.4

Mouse usage in AVEVA Bocad (1) Functional button (2) Representation button (3) Parameter button

Left mouse button = functional button Select function

Click menu entries by pressing the mouse button once.

Select elements

Pick depending on the function you have selected e.g. a grid, points or members by pressing the mouse button once.

(Individual) Choice of elements

Keep the key pressed while selecting all single elements by pressing the mouse button once.

Confirm choice of elements (individually)

Confirm your choice of elements by double clicking the latest element.

Choice of element (multiple)

Press the left mouse button and keep it pressed ; now draw a frame around the elements you want to select and then release the button. When drawing the frame from lower left to upper right, all elements within the frame are selected; when drawing the frame the other way round upper to lower left), all elements within the frame and those being (from touched by itright are selected.

Confirm choice of element (multiple)

The selection made by means of a lasso is confirmed by .

Middle mouse button = Representation button Refresh representation Press the middle mouse button once to refresh empty areas caused by the deletion of elements (e.g. refreshing of grid lines). Zoom in

Press the middle mouse button and keep it pressed ; now draw a frame around the region to enlarge.

Zoom out Shift representation

If you want to return the last representation after zooming something out, simply press the middle mouse button. Press the middle mouse button and keep it pressed ; draw a narrow frame to move the view. When drawing the frame from the left to the right the representation will be moved to the right; from right to left the movement will be to the left. This works analogically for the two other directions; the length of the frame defines the extent of the movement.

Right mouse button = Parameter button Open parameter dialog

After selecting a function you can open the according dialogue via right mouse button in order to define special settings for the application of the function.


20


4.5

Keyboard layout

Especially in the case of frequent working steps the use of keyboard commands can be very much quicker than the input with the help of the mouse and menus. Such keyboards commands are also available in AVEVA Bocad.

Functions of keyboard combinations The individual function of keyboard combinations is dependent on the context of the relevant application. Such contexts are: Input of coordinates (K)

In this context the coordinates for further processing within the current command will be determined.

Polygonal Lasso (L)

In this context the elements within the polygonal frame for further processing within the current command will be determined.

Selection of elements (E)

In this context the elements for further processing within the current command will be determined (picked, selected).

Selection of command (H)

Here you can repeat former commands (history function).

Initial context (I)

The Initial context is active after program start, or when no command is active.

Keyboard combinations exceeding the context ,

Abort of current command, quit current context, return to initial context

+k,

Change into the context of selection of commands, at the same time activation of preceding command

+c

Copy of element references into intermediate storage, abort of current command

+v

Use of the reference element of the intermediate storage at a coordinate which has to be entered

Input of grid data

5.1

Geometrical construction, coordinate directions

The grid forms a cube; it will be defined by the input of the grid coordinates. The user chooses those coordinates at the beginning of every project. Here it makes sense to choose a grid with dimensions which are as similar as possible as those of the design. You can use e.g. the axes of the building as basis for the selection of the coordinates, or as reference points for the outer dimensioning. A selected grid can always be supplemented by new ones (e.g. for secondary members) or be edited later. Thus, a cube can also be taken as the basis of the design of complex buildings.

By defining the first basic grid, the position of the global coordinate system will be determined. All grids which are created later refer to that srcin, even if the first grid is replaced by another one during the design process. The srcin of the coordinate systems is in the lower right corner of the basic diametrical perspective. The first grid receives the grid number '0' , the following grids receive serial numbers. Consider the dialogue Start New project, the input of the basic grid of the building (tab Project/Grid) has three groups of input lines: one line each in X, Y and Z direction with the corresponding designation of the grid (axis-row-level names).

5.1.1

Basic information concerning input

By default, the X and Y directions are interpreted as relative values. This means the entered values describe the distances between the individual grid levels. The input of the value z will be made as an absolute value. The default interpretation can be modified by placing the following abbreviation (incl. double point) in front of the catchment's values: r: for a change from absolute to relative values. a: for a change from relative to absolute values.


24


You can also start with zero for the catchment's values. It can also be started with a negative value. If you use negative values the grid will not start in the srcinal coordinates but in the corresponding value before. In case of following input: X: -5000,1500,500,3500 The grid will start 5000 mm in negative X direction, and then it will continue with a positive distance of 1500 mm, 500 mm and 3500 mm. In this case the srcinal coordinates are within the grid (the srcinal coordinates can be displaced via menu selection View > Edit > Properties).

5.1.2

Simple input of the values over individual sections

The following catchment's values will be separated by a comma. Example: x: 0,5000,2500,500,2500 A grid will be created with the distances of 5000 mm, 2500 mm, 500 mm and 2500 mm. In the case of Z-values the entered values are really levels and not distances like in the case of x and y. Thus the following input has the following meaning: z: 0,1250,2750,5200 Those levels will be created at 0, at 1250 mm, at 2750 mm and at 5200 mm.

5.2

Replicator sign

5.2.1

Reduced input of values in case of repeating distances

If you have repeating distances you can simplify the input of values. If you normally write e.g: x: 0,2500,2500,2500 You can also define the repeating distances as follows: x: 0,3:2500 The result would be the same: In both cases, three sections are created with each a distance of 2500 mm.

5.2.2

Reduced input of values in case of repeating ranges

If you have several ranges with same dimensions, you must not enter the values for these ranges as follows: x: 0,250,1000,1000,250,250,1000,1000,250,250,1000,1000,250 Alternatively you can also give a reduced input by summarising a range in square brackets: x: 0,3:[250,2:1000,250] If you apply any of both notations, three ranges with a distance of 250 mm, 1500 mm and 250 mm will be established when the grid is created.

 You can as well combine the different notations in one input line. In this case be sure to separate the distances and ranges by a comma.


25


5.3

Axis-row-level names

5.3.1

Standard designation of axis and rows

As a standard you will find in AVEVA Bocad numbers for the names of the axis - starting with the number 1 – and capital letters for the names of rows – starting with the letter A . That allocation of numbers and letters is automatic if no other values are entered in the input lines for the names of the axis and rows.

5.3.2

Modified designation of axis and rows

You can modify the standard designation of the axis by entering numbers, letters or combinations of letters. All entries of a line will only be separated by a comma. Here you will find some example for possible altern atives: M

By entering one letter or one number you will determine a new starting letter or a new starting number for the designation. If no other entries are carried out, the letters and/or the numbers of the designation of the axis will continue automatically.

G, First, H

If you have exactly three axes/rows, these will be designated in the above mentioned way. If you have more than three axes/rows, only the first three ones will be designated that way. The designation of the following axes/rows will refer to the last letter and/or the last number and continue on that basis. The next designation of the axis would then be Firsu , then Firsv .

 The automatic designation of the alternative

A’ which continues after ble because AVEVA Bocad refers to the last sign and not to the first.

5.3.3

B’

is for the time being not possi-

Level description

The default letter for the level description is K . That letter will be placed continuously in front of all level indications. If you want to have special designations for levels, you have to enter the required designation for each level. If you enter e.g. an additional designation after the letter K , only the second level will receive that designation. The following levels will receive again the first input - the letter K .

5.3.4

Grid designations spelled/numbered backwards

Depending on the input for the names of axes and rows the order of the grid designations can be modified by clicking the icons / . Instead of continuing the usual way of counting or spelling the indicated letter or the indicated number will be spelled or numbered backwards by clicking those icons.

5.4

Structure: Modify properties

You can modify properties of existing grids later, both of the entire grid and individual grid elements. In the Structure menu you will find the Grid element: Properties function. When using this function a dialogue will open where you can enter further settings for the grid definition.

5.4.1

Grid name

Each created grid can have both an unambiguous (automatic) number and a grid name. Normally, that name will be immediately determined at the creation of the grid. But you can also modify the name later by activating the option Grid name in the dialogue Modify properties in the area above in Grid and by entering the new name in the entry field on the right side. The same procedure is possible when editing the pen number. Here, the old pen number for visible / invisible lines must be replaced by new pen numbers. In order to make the modifications visible after the editing process, e.g. if they not automatically appear, you should recalculate at least in the current window. Confirm the input with OK, the window will disappear and a message will appear in the status line of AVEVA Bocad explaining the necessary steps of that function: 'Pi ck axi s -row-level 1 . Double click on any text element of that grid whose name shall be modified.

 The continuous recalculating of graphics would occupy too much capacity of the computer, especially in the case of bigger designs. You can, however, carry out any time a manual recalculating in any drawing window by clicking the icon .

5.4.2

Name of element

As well as modifying the name of the entire grid, you can also adjust individual designation elements. Do to this, open the dialogue Properties again.

 If you have modified the grid name during the preceding step, you can now open again the dialogue by clicking the right button of your mouse. This is a principle you will always find in AVEVA Bocad: once you choose a function, it will remain activated until you choose another one. So long as you can reach the parameters of the function by clicking the right mouse button. If necessary, deactivate the option Grid name and activate the option axis-row-level in the area Element. Enter the new name in the entry field on the right side, and then confirm your input with OK.


27


Follow the information of the messages and pick one or several grid elements by clicking (for each element) the left mouse button. Confirm your input by double clicking. The selected grid elements will now receive a new name.

5.5

Create grid

Additional grids can be created with the Grid: Create function from the Structure menu. In this case it has to be assured that all values of grid data always refer to the global coordinate system. The settings of the new grid including the grid name can be set in the dialogue of the function. If you want to create the new grid with a distance in X and/or Y direction relative to the srcinal point, you have to enter the values of these distances instead of the default zero value. Adjust the grids to existing ones in order to avoid them directly overlapping; therefore, they should be continued in a logical way. New grids will receive in addition to their name, an additional, continuously upwards counting grid number for their unequivocal identification.

5.6

Delete grid

If you want to delete a grid, make sure that always at least one grid will be left. Therefore it is not permissible to delete the last grid. To delete a grid select the Grid: Delete function from the Structure menu. The dialogue Delete grid will open. Select the grid you want to delete with a mouse click and close the dialogue with OK. The query 'Delete correct? ' will appear. The query is only displayed, when the Delete grid with query option is activated on the previous dialogue.

CHAPTER 6

Views

6.1

Main views

Designing with AVEVA Bocad is performed by means of so-called main views which represent two-dimensional planes within the global coordinate system. These working planes for the detailing process are defined by three points and each plane has an individual, local coordinate system.

The plane of the view always extends over the X and the Y direction with the Z axis showing from the plane into the direction of the viewer (similar to the three-fingerrule). All functions concerning main view planes are below the View menu.

6.1.1

Change

Depending on the working process it will be necessary to change the current design view in the main view window. Due to the default setting, main views for all grid planes are already created when the project is established.


29


In order to change into the currently displayed view Select the Main view: Change function from the View menu. All existing main views will be listed in the opening dialog. The represented plane of the design can be changed by choosing a view and confirming it with OK.

6.1.2

Create via grid elements

Creating views via grid elements is comparatively the easiest possibility to create new main views. If you want to create views for new grid elements or to modify the properties of an existing view, based on the a.m. procedure, you only need to determine the position in order to define the view by indicating the corresponding axis, row or level. The settings for this function are carried out after menu selection View > Main view/Create in the dialogue Create main view via point-grid-view and then the selection of the option Pick: Grid name. This dialogue contains various settings, but only one is relevant here: The options With axis or Against axis permit the selection of the view direction on a plane. The global coordinate system is also referred to. Against the axis means against the direction of the positive global coordinate axis. This means you have to determine from which side you want to look at the plane before creating it.

Let's take a simple example: you can look at any surface of a cube from the inside (you are in the building) or from the outside (viewer stands in front of the building). The following picture illustrates the view with axis (left) and the view against axis (right):


30


Since this function permits you to create various main views in one working process, the view directions for axis, rows and levels have to be switched separately. If you want to replace existing main views, you also have to activate the option Overwrite existing viewport, otherwise a message would indicate that existing views cannot be replaced. After confirming the settings with OK, the dialogue will disappear and you can pick grid elements in any view. Confirm your input by double clicking or with . The new views will be created.

6.1.3

Create via points

The creation of the view via points will be carried out by indicating three points defining the plane. The creation via points, compared with the automatic creation of a view, has the advantage that the adjustment of the plane can be determined by the order of the points. Select the Main view: Create function from the View menu and in the opening dialogue select the option Pick: 2-3 points. Enter the name of the plane you want to create in the entry line. You should use logical names for the planes so that the position can be easily recognized, e.g. axis_3, row_5 , level_ridge, etc. After confirmation of the dialogue with OK the message 'Pick plane point 1 between min. 2 and max. 3' will be shown. During the picking process the currently entered point will be displayed in the message. You can use the basic dimetry for picking the points or any other view or spatial representation. In the later view, the first picked point forms the srcin of the coordinate system and is positioned below in the left corner of the view. The second point defines the direction of the X axis. Later, it will extend from the first to the second point and is positioned at the inferior edge of the view. The last point defines the direction of the Y axis. Here, it is not important whether the third point is orthogonally on the first one, but that point is only there for indicating the direction of the positive axis. Finally, confirm that point by double clicking or by pressing . Thus the view is defined.

6.1.4

Delete

All created main views can be deleted, so you may delete, for reasons of clar ity, unnecessary views from the view list. The only main view you can never delete is the global plane. To delete views, select the Main view: Delete function from the View menu. In the dialogue of that function all existing views are listed, individual views can be selected by mouse clicking and confirming with OK.


31


6.2

Additional views

6.2.1

Perspective

– Checking

the construction with additional views After creating members and connections it is often useful to check the position of members and connection materials. The easiest way for this control is the 3Drepresentation of the complete toconstruction, where you can zoom comfortably points of interest. Perspectives are also useful for general drawings.

Select the Additional view: Perspective function from the View menu. In the next dialogue you can adjust some settings for the representation. These are explained in detail within the following chapters. One of the most important settings you can enter beforehand for the perspective is the scale. By this the output format is defined for the drawings to be created.

 See section 'Overview of drawings' for further information.

 The position of the members in the perspective is only displayed roughly. Perspectives are unsuitable for the precise definition of a position to the millimetre. There are other functions available for this purpose.


32


6.2.2

Section

For a precise identification of the position of members you can use the Section function. 

From the View menu, select Additional view: Section. According to the perspective you can adjust settings for the representation. As most important setting for the section the view direction to the members has to be defined.







The direction of the arrow shows the view direction of the section. The intersection plane is at the beginning of the auxiliary arrow, which will show the position of the later section. The value of the section depth describes the depth of the section. This is shown by the length of the auxiliary arrow.



Selection of a view direction for creation of a section.

Length of the auxiliary arrow shows the depth of the section.

After confirming the settings with OK, the dialogue will disappear. Now the location of the section is defined. With pressed left mouse button the first section arrow can be placed. When the left mouse button is pressed again and held, the section can be drawn over the area for the section.



Distance between the section arrows in accordance to the length of the section area.



After placing the second auxiliary arrow and releasing the mouse button the section is created:

6.2.3

Main views

Often it is helpful to see the construction from several points of view at the same time. For this you have the possibility to view several main views. These can be shown in several windows or together in one window. This also explains the term Additional view because you can create new views beside the Main view. From the View menu, select Additional view: Main view. A table with the existing main views is shown. Choose the view you need and confirm with OK.


33


As before, you can adjust settings for the representation in the next dialog, you can open any number of views:

Another possibility is to collect all views into one window. The procedure is the same as before with the difference of the activated option With new window . From the View menu, select Additional view: Main view. Choose the view you need and confirm with OK. Deactivate the option With new window in the opening dialog. The location of the new view will be requested. Place the view into the window with pressed left mouse button. Additional views can be treated the same way. All functions in the View menu below Additional view have this option With new window.

 This technique is not very useful to control bigger constructions, because with several views the size of the shown area requires a lot of zooming to get a special section. This procedure is advisable for e.g. the preparation of shop drawings.


34


6.2.4

Delete views in a window

When views inside a window are not required any more, they can also be deleted. Select in the View menu the entry Delete view. Click on the view to delete. The view is shown with a surrounding rectangle. It is also possible to select additional views. Please consider that you have to click on a line of the view and not into an empty region to select it. Now confirm the selection with and after a safety request the view will be deleted.

 In a window with several views the basic view cannot be deleted (the view shown first in the window). 6.2.5

Moving views

If the placement of a view was wrong or there is not enough space a view can be moved afterwards. From the View menu, select Edit: Move . Views to be moved can be selected without any additional settings. Same as for deleting, confirm the selection with . First a reference point must be defined, this is the point the view shall be moved to. In next step the view is moved with pressed left mouse button to the new location. In a window with several views, the basic view cannot be moved (this is the view shown first in the window).


35


Exercise: Creating views The following examples shall give a practical understanding of the function of the described creation of views via points. The main focus will be on the connection between the picking order of the three plane points and the resulting view.

Example 1 





First point: B1/bottom level (srcin) Second point: A1/Bottom level (defined X axis) Third point: B1/level 3000 (defined Y axis)

Picked plane and view direction shown on the right.

Created main view of this example: The result is a plane corresponding to the grid element (axis 1). The viewer is outside the building, looking at the interior of the building.


36


Example 2 





First point: B2/bottom level (srcin) Second point: B1/Bottom level (defined X axis) Third point: B2/level 4500 (defined Y axis)


Created main view of this example: The result of this point order is a plane (grid element row B), which is viewed from the interior of the building.


37


Example 3 





First point: A1/level 3000 (srcin) Second point: A2/level 3000 (defined X axis) Third point: B2/level 4500 (defined Y axis)


Created main view of this example: The result is a roof plane where the viewer looks from outside at this inclined plane.

 Although looking on a plane, it is nevertheless a three-dimensional view. This was shown in the previous example: the grid lines are not continuous in vertical direction, but are non-continuous. It is because of the visibility in the depth (Z direction). According to defaults of AVEVA Bocad, views are shown with a depth of 500 mm to the front and to the back. This means the grid lines – perpendicular to the plane – are visible 500 mm to the front and 500 mm to the back. Because the grid lines are running over the complete height of the grid with 4500 mm in total, the lines are cut at a depth of 500 mm. Also members located more than 500 mm perpendicular to the plane are not completely visible and thus intersected.


38

CHAPTER 7

7

Creating points

When detailing with AVEVA Bocad you will orientate yourself with the help of different spatial points. That may be points created by grids (grid points) or by a member (e.g. outline points of a HEA profile) or via the Points menu. There are different types of points in AVEVA Bocad. Point types in AVEVA Bocad Grid points

Grid points are created via the grid input. They are represented as in all views and can only be deleted together with the grid elements.

and are visible

 See section 'Input of grid data' for further information about grids. Pick points

Pick points are created via the Points menu or the icon bar Points Normal. Same as grid points, they are only visible in the view in which they were created and are represented as . They can either be deleted with the Delete point function from the Points menu or with the icon Delete point .

Database points

Database points are created by transforming existing grid or pick points. Database points are visible in any view and are represented with a drawback line and a serial number.

You can delete them with the Delete point function from the Points menu and the setting DB-points (or any) within the corresponding dialogue which will appear after clicking you right mouse button:

Points 2D/3D

Various functions in the Point menu either consider the creation of points in the plane (2D) or in the space (3D), e.g. the Add function or the Projection function. You will find in several functions the option With Z coordinate for distinguishing whether the creation of points will be carried out two or three dimensionally, i.e. whether the third axis shall be considered in case of picked points, this option can be switched on or off depending on you requirements.

 3D-points are only possible and allowed in a perspective.


39


7.1

Rule of signs

All actions serving to create points refer to a previously created point (or to a grid point). Normally a measure (in mm) or an angle (in grade) will be rotated from an existing point. These entries can be both positive and negative.

 It is also possible to enter repeating values as discussed in the section 'Entry of grid data'. An angle in AVEVA Bocad is defined in the mathematically positive sense, i.e. it is positive if it turns anticlockwise. You need a local coordinate system in order to enter a positive or negative dimension. This coordinate system is defined by the order of the points. As well as in the case of creating a plane the first clicked point (1) is defined as the srcin of the coordinate. The second point (2) defines the direction of the X axis. The Y direction (3) is positioned vertically on the x axis. Therefore, dimensions will be registered on their respective axis in dependence of their signs (4).

Positive signs may not be written in front of a dimension. In case of negative values it is obligatory to set a minus sign.

7.1.1

Perpendicular

With the Perpendicular function you can create one or several points from two existing ones. From the name of that function you can already recognize that the new point will then be perpendicularly to the srcinal points. Among other things, the dialogue Perpendicular shows the input line for entering the dimensions of the distances with their sign (if negative).

The input is a relative value; therefore you can create several points all with the same distance. If you want to determine the geometric positions (points) of the rafters on a purlin, you can enter 4 : 500 in the Distance field. As a result four new points will be drawn with a relative distance of 500 mm between each point. You may add additional points with different distances by separating them by commas.


40


After entering the distances (3) click OK. The message line shows 'Pi ck point 1 ' , after selection of this point (1) the message changes to 'Pick point 2' . After picking point (2) the program will calculate the points (4) and display them on the screen.

7.1.2

Parallel

The Parallel function is similar to the Perpendicular function. Here, two new points (4) will be created in the defined distance (3), parallel to the two picked points (1) (2). As in the case of the creation of points via the perpendicular, the distance of the parallel points can be positive or negative.

 A quicker alternative for indicating a negative distance instead of a positive one is to reverse the pick order of point 1 and point 2.

7.1.3

Lengthen

With the help of two points (1) (2) on the line a third one (4) can be created in one distance (3). The distance refers to the second picked point and can be both positive and negative. In the case of a positive value, a new point will be created in direction of the axis (first point is srcin, second one indicates the direction), in the case of negative values the point will be created against the positive axis direction. The function can be used in the 3D-space. To do this, you can use the option with Z coordinates in the parameter dialog. With this option activated, you can create a point with 3D coordinates in a perspective view. To do this, pick the points (1) (2) in a perspective view. If you work with the same setting (option with Z coordinate active) in one plane, the point will be projected into the plane (4) with the given distance (3).


41


7.2

Basic tools

7.2.1

Add

With the Add function you can create new points by adding distance values for the X, Y and Z axis with reference to existing points. The input of 1:100 or only 100 in the line DX of an existing point in local X direction, for instance, will create a new point with a distance of 100 mm. Correspondingly, the input of 3:100 in the line DY will create three points with a distance of each 100 mm from the srcinal point in the local Y direction. The input for the value dz will only be considered if the option With Z coordinate is activated and the srcinal point is picked in a perspective view.

7.2.2

Mirror

One important function in the point package is the Mirror function. Two picked points (1) (2) form the mirror axis (3) ('Pick point 1' and/or 'Pick point 2 of the mirror

axis' ). After defining the axis you can mirror as many points as you like (4). The last point must be confirmed with a double click or to create the mirrored points (5).

7.2.3

Divide line

In the Point menu you will find the Divide line function. In the selection list of the dialogue you will find various possible settings for creating several new points via an existing line. The division of the line can be realised by Number of points, Maximum field length , Rest P2, Rest P1, Rest P1&P2 or Free input.


42


Options of 'Divide line by' Division of line with Number of points

The division of line with Number of points divides a straight line represented by two points by a defined number of points. To do this, you can enter the number of intermediate points in the dialogue of the function. After confirming the dialogue with OK, pick the two end points of the straight line in accordance with the indications of the messages.

Division of line with maximum field length

The setting with maximum length has a similar function as the setting with Number of points. However, instead of a number of points a maximum distance value will be indicated. This means the system will calculate a regular division of

Division of the line with Rest P2 / Rest P1 / Rest P1&P2

Division of line with free input

7.2.4

the length which is smaller or equal in comparison with that dimension. These settings are similar concerning their functions. As in the case with setting with maximum length , an existing line will be divided. The division is, however, precise. Due to the precise division rests, i.e. lines will remain which are smaller than the indicated dimension. These can be distributed with different setting at different places. The rest lengths can either be distributed to point 1 ( with rest P1 ) or point 2 (with rest P2). It is as well possible to distribute regularly to both points (rest P1&P2). With the help of this function you can realise a division of line between minimum and maximum values. To do this, indicate the minimum and maximum values for the areas edge 1, field and edge 2. Then a regular division within these values will be created. The value Delta defines the approximation of the values in millimetres. AVEVA Bocad always orientates itself to the maximum values. After confirming the dialog, the usual messages will appear.

Intersection point

Calculates a new point on the basis of four given points, i.e. the intersection. Select the Intersection point function. The message bar will ask for the first two points, i.e. the points of the first imaginary line (1) (2). Then the points of the second line will follow (3) (4). The two lines, which may not be parallel, will finally be intersected (5).

 The G raphic inters ection function offers a similar function; with the difference that no points but lines can be picked directly. Also these lines will as well indicate the individual intersection.


43


7.3

Angle, arc, circle

7.3.1

Rotate angle

In addition to the described function which are carried out with the help of X and Y coordinates, there are functions working with angle functions. These include the Rotate angle function. This function creates a point on the circle arc via two pick points or via an indication of an axis which refers to the local coordinate system. In dialogue Rotate angle , enter degree value the in the input field Angle . Here, thearule of signs is applied as well. If the default option Basic line: Pick is activated and the dialogue closed with OK, the message line will ask to pick two points (1) (2). After defining the imaginary line, a new point will be created (4) that will be rotated around the first pick point in the indicated angle (3) and the distance first to the second pick point.

If any other setting than Pick is selected for the Base line in the parameter dialog, only one point has to be picked. Based on this point (1) an angle (2) referring to a new point (4) will rotate in the set Distance (3) in direction of the local coordinate axis (+/- X oder +/- Y).

7.3.2

Divide angle in half

This function will create a new point via three pick points. First of all, the message line will request a centre of a circle (1), then an additional point on an imaginary circle (2). The third point defines an angle which refers to the centre of the circle (3). The new point (4) will rotate in the middle of the angle on the circle.


44


7.3.3

Divide arc

The Divide arc function creates any number of points, on an arc with regular division, via three pick points or two pick points and the angle data. To do this, the following indication is required in the function's dialog: a value for the angle (if option Angle is activated), and the number of points to be created.

After confirming the dialogue with OK the pick points can then be selected (1) (2) (3). AVEVA Bocad will then create a new number of points (5) in regular distances, limited by the second and third pick point, or by the arc around the first pick point and limited by the angle (4).

7.3.4

Intersection Circle - Line, Circle - Circle

In the menu Points menu you will find below Circle intersection the Circle-Line function and the CircleCircle function. With the help of these you can create new points as intersections to an imaginary circle. The first step for both functions is identical: first of all, a circle will be defined by two picked points - centre of the circle and radial circle point. During the following working steps this circle will be emphasised with the help of a helpline. Intersection Circle - Line

In this function, in the second step you have to pick a line via two points. When calculating the intersections the extension of the line will be considered as well. The new points will be created at both intersections with the circle.

Intersection Circle - Circle

In this function an additional circle will be picked in the second step. The two new points will then be created at the intersections of the second circle with the first circle.

CHAPTER 8

Creating members

With the basic setting of AVEVA Bocad you can create all standard profiles (e.g. UB, UC, RSC, RHS, etc.), members with geometries to be determined (e.g. plates or bars), cold rolled sections (e.g. ZKRUPP, STABA, etc.) and catalogue profiles, e.g. for glazing and metal construction. First select the Create profile function for creating of profiles from the Members menu. Typical for the working style in AVEVA Bocad, you can open the dialogue Create profiles < Members by clicking the right mouse button: (1) Selection of the profile type to be created: Standard profiles as well as profiles with definable geometries 





Special profiles Profiles catalogue (default or customer defined).

(2) Preview configuration (3) Optional preview of the set position parameter and the selected profile type - the eye symbol indicates the view direction on the creating plane.

8.1

Indication of member describing data

8.1.1

Initial mark number The initial mark number serves for preliminary numbering of created members. When creating a member, the default number will be prefixed with 'S ' (indicating initial mark number), e.g. 'S300' .

The definite numbering will be carried out later by the marking. The initial mark number has two properties: 

With the first property you can structure the numbering process. So the entry (default is 1) indicates the start value for the numbering of the mark number. For example, you can assign the number block starting with 300 to such members as e.g. roof purlins. To do this, enter 300 in the entry line. Unless you modify the number, all newly created members will receive now an initial mark number starting with the set value 300 (numbers will be counted upwards).


46


The second property of the initial mark number is to set members in accordance with bill of materials or to create them as dummy member. Dummy members are members at the site as e.g. bases or as well steel components not belonging to the delivery scope; therefore, they receive the initial mark number '0' .



8.1.2

Designation

The designation is a precise description for a member. You can define e.g. a member (in addition to the profile name) by its function, such as support or beam. You do not have to consider any convention when entering your description in the relevant entry line beside the designation . You can open a list containing various designations by clicking the button besides the entry line.

 Later the selected designation will be a relevant distinguishing characteristic during the marking. Concerning other properties such as profile and lengths, identical members will be marked with different numbers if they have different designations, e.g. BEAM - beam, or Beam .

8.1.3

Profile types

As mentioned before, you will find various profile types as default entries in AVEVA Bocad. You have to observe the designation of profiles in order to find them when they will be created. If you make no entry in the dialogue Create profiles < Members besides the button Profile and then click it, you will open a complete profile list. This profile list contains all standard profiles of the AVEVA Bocad profile database including all usual profiles in steel construction. In addition to the profiles of the list you can create profiles with individual geometries, e.g. plates 'PL' (see the following tables concerning profile types). Now you can select the required profile from the profile list. The existing list is very extensive and it will take time to browse the entire list. One useful function in the dialogue Profile list (as in other profile dialogues in AVEVA Bocad) is to jump through the alphabetically sorted list. To do this, mark any entry in the list with the help of your mouse. Enter a letter; the mark will jump to the first entry of this list beginning with that letter. By quickly entering a combination of letters (e.g. IP) you can also search profiles beginning with those letters.


47


The second search for the profile list is a filtered list, i.e. the indicated list can be reduced to one certain profile type. To do this, first enter the name of that Profile type in the entry line beside the button Profile , e.g. HEA. If you click then the button Profile, you will only receive the profiles of the HEA profiles: Of course, you have also the possibility in AVEVA Bocad to enter the profile type of a profile row directly, e.g. HEA200. Especially in this case you have to observe a particular notation (compare with the following tables).

 In case of standard profiles you can use as well ½-I-profiles. To do this, enter e.g. 1/2IPE300 in the dialog. In case of plates there is e.g. an unlimited variety of geometries therefore, they are for the time being not included in the profile list. After shifting a plate this will automatically be adopted in this list.


48


8.1.4

Materials

Via the button Material you can open a selection list which contains all usual material names and allows freely assigning one of the entries to the profile.

8.2

Creating members in longitudinal view

A member with its longitudinal axis will be placed parallel to the reference plane. Normally the reference plane is identical to the plane in the view where the first member-defining point will be picked.

8.2.1

Number of creation points

You can carry out the creation of members in longitudinal view via one or various points; the first pick point always determines the srcin or the start of the longitudinal axis. The following determination of length and alignment of the member is using the setting of the option Points . Creating via one point. When creating a member only by picking the srcinal point, you will determine the length of the member with the help of a fixed value Length . The member direction will be calculated via the value Angle determining the rotation of the longitudinal axis of the member around the picked srcinal point: (1) Line of sight on creation plane (Z axis). (2) Rotation of the member around the srcin.

Creating via two points . When creating a member with the help of the setting 2 points, the first pick point will determine the srcin and the second pick point the end point of the longitudinal axis of the member and thus length and alignment of the member: (1) Line of sight on creation plane (Z axis). (2) Origin and end point of the member.

 The creating forms of profiles via n points and the creating of bended members will be treated separately in the Manual 'Basics 2', section 'Curved members'.


49


8.2.2

Setting of the profile view

There are different views depending on the position from which you look on the member. AVEVA Bocad offers four different profile views in order to facilitate the placing of members in different views: front view, top view, rear view and bottom view. These views can be set before shifting in long view. The Front view is basically defined as the view on the web (in case of standard profiles), respectively view on the surface in case of plates. While an UB profile has only two different views, since the top and bottom view and the front and rear view are identical, e.g. an unequal L profile will be represented differently in all switchable views. The four available profile views in the example of an uneven L profile: (1) Top view (2) Front view (3) Bottom view (4) Rear view (5) In addition to the set profile view you can indicate a free Angle for carrying out more precise rotations around the member axis.

It is recommended to activate the option Preview in the dialogue of the function in order to check before creating how the current settings will determine the later orientation of the member in the reference plane.


50


8.3

Location determination via member anchor

8.3.1

Member anchor

Up to now, we took as a starting point that the position of a member will be determined alongside its middle axis between a picked srcinal point and an end point – either picked or by entering a value. The position of the member and its anchorage in the reference plane is determined by the of the profile and each 50%middle of the point member is above and below the reference plane and the member is in the middle of the selected create axis.

If you want, however, that a member levels with its superior left profile edge at the create axis, you can modify the default anchorage of the member with the help of the setting matrix Position.

In the same way you can orientate the location of the member to the create axis via the setting matrix at each of the nine possible anchor points. Here, you have to observe that the anchor points always refer to external outline of a member, depending on the profile type, those anchor points do not touch directly the member.

By this, you can create a member above, in the middle of or below the reference plane by using the vertical setting matrix of the Position , by using the horizontal setting matrix you can align the member anchor with regard to the create axis to the left hand, in the middle or to the right hand. In any case one point of the external outline touches the create axis.


51


8.3.2

Auxiliary shift

By entering a value for depth and transverse shift (DZ or DY) you can additionally shift the member anchor set in the position matrix to create a tolerance or an overlapping between the member and the create axis. The definite location of the member will thus be determined by a picked axis and the corresponding anchor point on it and, additionally, by the set depth or shift in Y direction. The depth shift DZ will result in a shifting of the anchor alongside the Z axis of the creation plane. A positive shifting value will create a tolerance and a negative value an overlapping of member and create axis if the anchor is located at a vertical external point of the profile outline. If the anchor is located vertically in the middle, you will always shift upwards, respectively downwards with a negative value. Depth shift of the anchor point via a positive value (1) Z-axis of the creation plane (2) Creation plane

Depth shift of the anchor point via a negative value (1) Z-axis of the creation plane (2) Creation plane

Analogically, a transversal movement DY causes the movement of the anchor along the x-axis and it evokes a tolerance when the value is positive and an overlapping of the member and the axis of creation when the value is negative, when the anchor lies at a vertical external point. If the anchor is located vertically in the middle, you will always shift to the left side, respectively to the right side with a negative value.


52


Transverse shift of the anchor point via a positive value (1) Creation axis (2) Creation plane (x-axis)

Transverse shift of the anchor point via a negative value (1) Creation axis (2) Creation plane (x-axis)

8.4

Creating members in side view

In addition to the previous explanation how to place members longitudinally in the creation plane, you can also place members in the depth of the creation plane. When choosing this type of creation you will thus create members in their side view, i.e. their longitudinal axis will be created vertically to the creation plane and you only have to pick the srcinal point for the member in the creation plane. You can determine the length of the member to be created (in Z direction of the creation plane) by entering a value in the entry line Length . In addition, you can indicate a rotation around the longitudinal axis of the member by entering a value in Angle.

Here you can as well anchor the longitudinal axis of a member via the matrix setting concerning the position at nine significant locations.

 See section 'Creating members via member anchors' for further information about anchoring. An additional shifting of the set member anchor in the direction to the create axis is possible as well. This will, however, not be carried out as depth or transverse shift, but with the values X and Y which will shift the picked srcinal point for the member in X and/or Y direction in the creation plane. You can enter both positive and negative values.


53


When choosing this type of creation, you can exactly control the positioning of the member in the depth, i.e. its length alongside the Z axis of the creation plane, with the help of the three settings front , middle or back and, if required, by using the additional positive or negative shifting value z. This value corresponds to the depth shift explained in the section Creating member. When creating a member in the depth to the front, it will be completely above the creation plane, and when shifting to the back it will be completely below the reference plane. At a centred movement the member axis is laying on the plane of creation, a symmetric profile will therefore lay half above and half below the plane of creation.

8.5

Creating of plates

8.5.1

Creating via profiles

Plates can be created longitudinally via the Create profiles function. The procedure is identical to that already described in section Create members in longitudinal view . You can enter individually the profile dimensions of the plate in the dialogue of the function in the entry field Profile by entering the abbreviation PL and then the profile thickness and profile height, e.g. PL25*200. Once a plate has been created its profile is registered into the profile list and from now on you can load it from the profile list by using all possible filters.

 See the section 'Profile types' for further information about possible filters. 8.5.2

Via outline plate

With the help of the Outline plate function from the Members menu you can create plates with a defined thickness and free outline. The contour plate will be defined by picking contour points; therefore, you should have created suitable pick points before using the function. In addition to the designation BL, you only have to indicate the plate thickness and, if required, the depth shift for the profile name. The latter value indicates the location of the plate (its thickness to the creation plane), i.e. whether the below plate or shall bemiddle created above, in the of the picked outline. You can also influence the geometry of the plate with a value in Expansion . In case of a positive value the plate has an overlap, in case of a negative value it will use this dimension.


54


When you confirm the dialogue with OK, you will see the messages for picking the outline points of the plate. The picking order can be carried out either clockwise or anti-clockwise. The last point must be confirmed with a double click or with to create the final outline plate.


55

CHAPTER 9

9

Editing members

After creating members it is often necessary to edit them, i.e. to modify m embers concerning their form and geometry. You will find all required steps for working on members in the Edit Members menu.

9.1

Length modification

Editing of members concerning their length means different requirements. For instance, one situation requires a merely dimensional shortening, another one adjustment in dependence of the position of another member. The different types of function are grouped in the Length modification function of the Edit Members menu. After selection of this function you can open the dialogue Length modification < Edit: Members for further settings by clicking the right button of the mouse. In the left dialogue area you can choose the Type of member editing via the tree representation, in the right dialogue area you will then find different possible settings.

9.1.1

Lengthen and shorten

In the dialogue of the Lengthen/Shorten function you can enter a value in mm into the Distance field on the right side; the member will be lengthened by this value. In case of a negative distance value the member will be shortened correspondingly. Additionally, you can also indicate with Test whether an individual member (this is normally the case and thus the default) or a complete construction group shall be edited. After confirming the dialogue with OK you can pick members to be edited in accordance with the messages until terminating your input with a double click or by pressing . Then you have to pick the member edge where you want to modify the length. To do this, you only need to click into the area of the member edge, i.e.and younot need not width click itorexactly. member to the height. The length modification in this function refers only to the length of the Lengthening of an I- profile by 500 mm


56


9.1.2

Adapt

With the Adapt function you can adapt members with their front surface to a plane. The adaptation can be carried out two ways: either Projection to axis or with 2 or 3 points (the third point will be used for creating a compound angled section). You will also find this function in the dialogue Length modification < Edit: Members . It will also be activated by selecting the type, i.e. in this case Adapt. For the adaptation via Projection on axis you only need one point to determine the adaptation place. Therefore, the cross section will be adapted directly to the point. If you choose an adaptation plane with 2 or 3 points , you will require the corresponding number of points. With the help of this setting you can adapt members to an inclined plane.

(1) Adapt member via two points (2) Adapt member with projection on axis

Both settings permits you to enter a positive or negative Clearance in order to modify the distance of the new member edge to the picked axis.

9.1.3

Adapt to a member

By using the Adapt to a member function from the dialogue Length modification < Edit: Members you can carry out a similar member editing as described for the setting Adapt. The only difference is that the adaptation plane will be offered by another member as tool-part. In case of this function, you can carry out the setting Adapt to 3D surfaces, Adapt to external volume and Adapt to member extreme in the dialogue by using the selection list Adaptation plane. These refer to the tool-part member to which the to-be-adapted member shall be adapted and have the following meanings:


57


Adapt to 3D-surfaces Alongside the axis of the tool-part member it will be checked which edge of the to-be-adapted member will be touched. This edge will be the adaptation plane.

Adapt to external volume The tool-part member will be surrounded by an external volume. This edge of the external volume will be the adaptation plane.

Adapt to the member extremes If a member rotates around its own axis, this member can be surrounded by a cladding running through the extremes of the member.

In addition to these settings, you can control whether tool-part members shall be considered Only if members intersect in the dialogue Length modification < Edit: Members .

9.1.4

Cut

As in the case of Adapt, the member will be shortened via Projection on axis or via 2 or 3 points , it is also possible to add a Tolerance . When executing this cut alongside a plane, the front surface, however, will not be adapted automatically; rather you have to indicate the so-called waste side of the member. After confirming the dialog, the plane will be determined as in the case of the Adapt function. Then, in accordance with the message 'P ick s ide to rem ove (member-point)' , pick the side on the left of right part of the section plane. After confirming with double click or this waste side will be cut off the member.

9.1.5

Split

During the splitting process a member will be divided into two separate members. Here, you can split a beam with a Tolerance, e.g. to insert plates for a beam joint into the section.


58


9.1.6

Regroup

With the help of this function you can group various members. As a prerequisite, the members have to have the same cross section and an identical member axis. A direct contact area between the members, however, is not required. If you edit e.g. two beams by using this function, the new regrouped beam will extend over the complete length of the srcinal beam and the previous spacing

9.2

Volume operations

As in the case of length modification, the Volume operation function summarises several functions types. They can be selected from the dialogue of the Volume modification function in the Edit members menu.

9.2.1

Punch

With the help of the Punch function, you can punch tool-part members with to-be-adapted members, i.e. by using a tool-part member you can remove a volume from a to-be-adapted member. In contrast to the other editing functions for members described previously, during the punching process a volume will be created as default which will then be deleted after having been punched. In the following example, a HEA200 shall be punched with a plate so that this one will be coped. Step 1: Creating a HEA 200 Step 2: Creating of a punching volume (1) Create a plate as punching tool. Edges may not be congruent with the edges of the tobe-adapted member.


59


Step 3: Executing the Punch function (2) according to message first pick the toolpart … (3)

… then

pick the to-be-adapted member

Step 4: Deleting the punching volume (4) Eliminating of punching volume with menu selection Members > Delete

When punching members, the surfaces (edges) of the tool-part member and the to-be-adapted member must not be congruent for carrying out the intersection. In the right example, the punching is not possible:

The Punch function deletes areas of the to-be-adapted member; it creates, however, no new members even if they would be created physically by the tool-part volume. Thus, in case of a punching volume no waste member, which could be deleted in the second step, will be created but only the hollowed section will be eliminated. (1) Result after punching (2) Remaining web area after deleting the punching volume (3) Waste


60


To avoid this you can alternatively set the function of the dialogue that a Tool modification will be applied for the punching. In case e.g. of a tube you would punch with a circular profile.

(1) Result after punching with a tool modification (2) Web area after deleting the punching volume (3) Waste

9.2.2

Merge

The Merge function allows you to combine and/or blend outline plates. Thus, it is possible to create irregular elements, e.g. in the area of concrete bodies. That means you can combine bodies at their contact areas.


61

CHAPTER 10

10 Editing outline plates The Outline Plate function from the Edit member menu is for modifying existing outline plate in the outline plane of that member. When the function is selected, the representation type of the outline plate needs to be defined, before a new window is opened for its processing. When confirming this with OK the message 'Pick member' appears. The outline plate can be picked on any view, and then a new window is opened where the member is represented in front view (1). In this window you will find functions in the Contour menu to edit an outline plate (2).

Outline editing functions Highlight

First of all, you should check whether you have chosen the correct member for working on it. To do this, select the highlight function. The current member to work on will lighten in an outline of a different colour.

New plate thickness

A new plate thickness will be assigned to the outline plate. By activating the function the dialogue for entering relative dimension for moving will appear. Enter the new overall thickness in the entry field Thickness. In addition, you also determine the Modification with regard to the depth by choosing Front, Symmetric or Back. This setting refers to the middle axis of the outline plate. Selecting this setting means, the new thickness will be divided symmetrically at front and behind, otherwise, depending on the selected direction, to front or behind.


62


Outline editing functions Move outline points

Selecting this function means, outline points will receive new coordinates in the outline plane. After selecting the function, the point will be selected. A crosshairs will appear and by pressing your left mouse button you can now determine the new place of the outline point. With the help of the pick mode you can e.g. pull to a pick point or to an existing member edge.

Move outline

Unlike the Move outline point function

points with value

the new place of the outline point can be determined by using relative values. The procedure is similar to the Move outline point function. After moving the outline point a dialogue is opened where the relative values (between old and new position) can be entered for the X and Y direction.

Add outline points

You can add new outline points to the outline of the member so that the outline of the member will adopt a new shape. To do this, pick the new position on the member outline where the new point shall be created. Then the position of the point is defined while keeping the left mouse button pressed. With the pick mode set to Free an arbitrary point can be defined, but it's also possible to define a new point beforehand e.g. via the functions of the Points menu. The new outline point will then be pulled on that point with the pick mode Pick points.

Move outline

With the help of this function you can

edges parallel

move existing outline edges in parallel direction. While doing that the length of the moved edge will be maintained. During the moving the adjacent edges adapt themselves concerning length and alignment.

Move outline edges parallel with value

Similar to Move outline edges parallel the edge to be moved has to be picked and pulled in the required direction. Afterwards, a dialogue will be opened where you can enter the parallel distance.

Move outline edges randomly

Unlike the parallel moving of an outline edge, you can move an edge as you like when applying this function, i.e. the edge to be moved will maintain its length and the adjacent edges will adapt to the moving with regard to their length and alignment. If you activate the function you have to pick the edge. The anchor point is on the centre of the edge. With this point you can move the edge.

Delete outline points

Existing outline points will be deleted. However, you have to keep at least the three required outline edges for describing the outline plate.

Delete outline edges

With the help of this function you can delete outline edges. However, you have to keep at least the three required outline edges for describing the outline plate.


63


Outline editing functions Add snipe

You can add a snipe from an outline point. The corresponding outline point will be picked and then the entry dialogue for the relative values will appear. With the help of this value an angle cut from the picked point will be carried out.

Add concave corner

With the help of the Add concave corner function a concave rounding at the picked outline point will be carried out. After picking an outline point, a dialogue for entering the value will be displayed. The Distance between the rounding and the pick point can be evenly moved in the X and/or Y direction. When selecting one of the two last options an additional entry field for entering the values will be shown below Distance . (1) Radius of resolution in mm (2) Number of base points for representation of the rounding (3) Picked outline point

Round corners

The procedure of this function is similar to the Add concave corner function, with the only exception that a convex rounding will be carried out. With picked contour point the dialogue for entering relative dimension for moving will appear. (1) Number of base points for representation of the rounding (2) Number of base points for representation of the resolution (3) Picked outline point


64

CHAPTER 11

11 Welded connections In the Connections menu you will find various functions for creating connections. No matter whether you want to create a seam or a bolted connection (this is shown in the next section), you have to meet various requirements in order to work with the connection functionality in AVEVA Bocad: 

You have to select a reasonable view, e.g. for use with the Section function or the Points/line function available from the View menu.



Points for seams or bolts must already be created; you can then use the function in the Points menu.



The members to be connected, e.g. beams and end plates, must suited to be picked.

11.1

Create weld seam automatically

With the help of the Automatic Weld function in the Connections menu two or more members will be connected automatically with each other. Contact areas between the partners will be found automatically. If you want to have another thickness at the seam and web of the weld connection, select the option Web unlike flange . In this case additional entry elements for the Weld thickness flange will be displayed in the dialog. If the option Web as flange is activated, regular weld thicknesses with the value Weld thickness web will be created. One condition for the use of this function is that the connecting partners must be suitable to be picked; another condition is that the parameters have been adjusted in the dialog. Additional settings concerning the generation of weldings can be carried out on the tab Additional data. After selecting the function, the first member with welding and the member to be welded have to be picked. The second connecting partner determines the course of the welding. (1) Weld carrying member (2) Member to be welded (3) Weld will be created in the contact area of respective members


65


11.2

Controls: Info > Connection

For controlling the created connection you will find various informative functions in the Info menu. With the help of the Connection: Properties function you can e.g. load a text survey concerning a connection. To do this, select the function via the menu, then pick an existing connection. The information will be displayed in a dialog.


66

CHAPTER 12

12 Bolted connections

12.1

Terms

Bolt group

In AVEVA Bocad, a bolts group is defined as bolts which are generated with functions (this can be one or more bolts). The group consists of bolts connecting the same members with each other. Thus, these bolts are the same type of bolts, i.e. the have the same garniture, material, length, etc.

Loose bolts

Loose bolts distinguish themselves from bolts/studs in the sense that they are directly assigned a length. The length is not calculated by AVEVA Bocad. Loose bolts are applied e.g. for connections at dummy members, e.g. at concrete. They are established in the same way as bolts/studs.

Material length

Generally, the material length corresponds to the total of all thicknesses of material to be connected.

Garniture

A garniture includes all additional elements such as nuts, bolts, etc.

Bolt length

Material length + garniture + jutting out. If you select e.g. a bolt with a length of 63.5 mm, that bolt which can be delivered quickly will be chosen with 65 mm.

Controls

12.3.1 Info > Connection The Connection: Properties function in the Info menu (already introduced in the preceding section 'Welded connections') can also be used for receiving an informative survey of a bolted connection. To do this, select the function via the menu and pick an existing bolted connection. The information will then be displayed in a dialog.

12.3.2 Search > Bolt connectivity The Check connections: Bolt connectivity function from the Search menu offers automatic control of bolt mounting. In the dialogue of the function you can link a nut size to a bolt type by choosing the button 3D control on the tab Parameters . With the help of this value each bolt of this type will be controlled concerning its connectivity. After the use of this function, all bolts without connectivity will be emphasized with a tool symbol. In addition you will see a survey of all bolts without connectivity in a new window. If all relevant bolts have connectivity this will be indicated in an Empty result list. In this case all bolts with the bolt size selected in the list have connectivity. After applying the function, all represented tool symbols with the Delete connectivity tool function from the Search menu can be deactivated again in all windows.

12.4

Work on bolt groups

12.4.1 Delete completely / individually With the help of the Delete connection function from the Connection menu you can either delete individual connecting elements from a connection group or eliminate a connecting picture completely. After opening the function, the delete mode can be switched via the options Connection group or Single element. By activating the option Connection group you can delete a connected connecting picture. You only need to pick an element of the picture and confirm your selection.

If you activate the option Single element, you can delete individual connecting elements from a bolt group in any view. Only the picked elements will be deleted and the new connecting picture will be represented.

 If you delete e.g. a single member from a bolted connection (e.g. filler plates in a bolt group), the bolt group including holes in that member, but as well in all other existing members will be deleted.

12.4.2 Move The Bolt: Move function in the Edit connection menu refers to the moving of individual bolts in a bolt group. First of all, change to a view where you can see the bolt group with the viewing direction in or against the bolt direction of the bolts. By selecting the function, the dialogue for entering relative dimension for moving will automatically appear. After entering the dimensions you can pick one or several bolts. Bolts are then moved with the specified dimensions relative to the srcinal position.


69


12.4.3 Re-calculate With the Bolt: New length calculation function in the Edit Connection menu you can calculate again a selected bolt. You have no possibility to apply a bolt of another type. One possible application of this function is e.g. to integrate new connecting members into a bolt group. In the following example a point of roof ridge is created, whose ridge plates will be connected with bolts (in a bolt group). Afterwards we will apply filler plates which require a new calculation of the bolt group.

After selecting the function the following entries populate the dialog: (1) Length shall not be maintained (2) Direction shall be maintained (3) Admit that various bolt groups will be created (4) Connection partners shall be searched automatically

The result of the new calculation is shown on the right side.


70


12.4.4 Exchange With the Bolt: Exchange function you can later modify bolt connections. If the function is activated, you can load the corresponding dialogue by clicking your right mouse button. Here you can make your indication with regard to the bolt type to replace the previous bolt group. After com pleting your indications, confirm the dialogue with OK and pick the corresponding bolt group. The previous group will be replaced by the new bolt group.

Exercise: Bolted connection MSH at IPE profile Using the following example (fixing of a MSH profile alongside a longitudinal wall at an existing frame support), the various possibilities of the function will be shown. Both members, a support IPE360 (1) and a transom MSH100*100*4 (2) will be connected with each other one after the other in different ways. The initial situation is as shown on the right:

Alternative 1: MSH+tubes long/rest short material length In AVEVA Bocad you can connect profiles by a bolt with a long material length. Normally, you need long material lengths if a bolt is going to completely penetrate a profile. Select the Bolts function from the Connection menu. The right mouse button opens the dialogue of the function, where you can enter the following settings. Click the button beside Designation in order to get an overview concerning the corresponding diameters: In the opening dialogue you can select a bolt with the corresponding diameter. This bolt has a length, the length, however, will also be maintained if the bolt is too short or too long (Indication of length is optional, if no length is indicated it is calculated automatically).


74


Activate the option With bolt length calculation - Designation without length in the dialog. In this case the required bolt length will be calculated automatically and the next bolt with sufficient length will be selected from the database.

Then you have to modify the bolt length in the dialogue Create Bolt Anchor Loose. The entry RHS+CHS long/rest short grip length has to be selected from the selection list Grip length. Here, it is also important to activate the option Only create bolt if in database. If you did not indicate the length when entering the bolt and if you want to create the bolt even if it does not exist in the database, the material length will be calculated automatically with this setting and the bolt will be generated with the correct length. The dialogue should now be represented as shown on the right.

After confirming the dialogue with OK, pick now the bolt point in front view on the longitudinal wall. Finally both members to be bolted have to be IPE360 picked: The (1) and the MSH100*100*4 (2). The order is not relevant for this. The bolt direction of the bolt is from the exterior, i.e. into the MSH profile, when you look from the exterior on the longitudinal wall.


75


The result of this example is a bolted connection with a SKG 12*140.

Alternative 2: Separated profiles will be connected via short material lengths This alternative connection is based again on the initial situation of the exercicse. The two profiles, the support IPE360 and the bolt MSH100*100*4 shall be connected by the bolt SKG12 with short material length. In this case, however, no length will be indicated for the bolt but be calculated automatically. Concerning the bolt connectivity, an additional opening will be shouldered in the MSH profile. In order to generate this opening, a generation of bolts with a second hole tolerance will be carried out, here you have to indicate a diameter for this hole tolerance. As you can recognise from the term hole tolerance, the overall diameter of the opening is composed of the bolt diameter and the hole tolerance. In this example the opening shall have a diameter of 40 mm. If you use the bolt SKG12 you will require a second hole tolerance of 28 mm. Additionally it has to be specified where the opening should be located. Before creating the bolt, an internal examination checks where the bolt hits and the profile. These penetration points can be indicated as position for the second hole tolerance: (1) Insertion direction (2) First hit: In this position the bolt hits a profile for the first time (3) Second hit In this example, the opening shall be at the first hit. Thus, the following settings are required in the dialogue Create Bolt Anchor Loose, considering the previous demands with regard to the connection: (1) Bolt without length indication (2) Settings for the second hole tolerance (3) Selection short material length


76


After confirming the dialogue with OK, pick now the bolt point in front view on the longitudinal wall (same as in first example variant), then pick the two members to be bolted. As a result a bolted connection MSH at IPE profile for separated profiles will be created; with bolts with short grip length.


77


Exercise: Stud shear connector on inclined profile In the following example it is shown how stud shear connectors can be set in a grid on an inclined support. As support an IPEA400 is used; and as stud shear connector a KOD22*125. The studs shall be distributed regularly on the superior flange of the transom. The studs shall have a distance of 220 mm in direction of the support axis and a transverse distance between each other of 100 mm (studs in two rows). To generate the grid on the flange, first you have to change into the top view of the inclined support. To do this, select the Additional view: Member plane function from the View menu. Here, activate the Top view , select as Reference the setting Flange/Web surface, then pick the support. Now select the Create studs/nuts …function from the Connection menu and open the dialogue of the function with a right click of the mouse to set it up in this way: (1) Used stud shear connector (2) Button sets values to default (i.e. ’– 1’) (3) Button Create grid division Activate the option Points on the tab Points other in the dialogue and set Rest P1 & P2 for the grid division in the selection list. Then click the button Grid division. In the next dialogue you can enter the division values for the stud. Set the Division measure for the first side (later set by subsequently picked points P1 and P2 in the connection) and the second side (later set by subsequently picked points P3 and P4 in the connection).

If the dialogue is closed with OK, the input of the grid srcin is instantly possible:


78


After defining the grid srcin and the points P1 to P4 you can leave the dialogue Create Bolt Anchor Loose with OK. Now pick one of the created grid points as bolt point and confirm this with . Then the member has to be picked. As a result the studs will now be created on the grid points.

CHAPTER 13

13 Backup procedure During the design phase, unintentional modifications such as deleting members, drawings, etc. occur, or that data will be deleted due to a power failure or incompatibility in the system. It is not always possible to enter values again, and normally it takes a lot of time. You should therefore make backups of the project in regular intervals. In addition AVEVA Bocad offers various ways to save data; which is now explained in detail.

13.1

After automatic query

After an interval to be set individually by you, the query 'S ave boc3db? ' will appear (the abbreviation 'boc3db' stands for bocad 3D database). This query must be answered either with Yes or No in order to be able to continue the work in AVEVA Bocad. If you confirm with Yes, the current version of the structure design will be saved in boc3db (and also in the backup directory \boc3db.sav ) below the current project directory. Thus the file boc3db corresponds to the current representation of the structure. Otherwise the previous backup will be maintained, i.e. no further design steps will be added the database. With the Saving interval function from the Extras menu you can set the time between two safety queries as well as name and position of the backup directory. Enter the saving interval in the textbox Interval in minutes. The saving interval will, however, only be modified after the next safety query. The name of the backup in the textbox Directory to save to must be different from the file boc3db (without extension)

 See section 'Specific backup after a design step' for further information.

13.2

Specific backup after a design step

If a backup is required at a specific moment, use the Save as ... function from the File menu. You can add a name extension to the file boc3db . The default backup name is boc3db . You can enter any file extension without using special characters.

If you do not indicate an extension for the backup, the former boc3db.sav will be overwritten. If you enter, however, a new extension, the former backup will be maintained and an additional one with a new extension will be established.


80


For example, you may enter an extension composed of the current date (e.g. boc3db.120418 ) at the end of a working day. Be sure to create always a new backup when selecting this procedure. As a result, you may have various backups in your project directory, although you do no longer require them. This will fill the hard drive unnecessarily and may prevent from saving project data because of a full hard drive.

13.3

Saving when closing a project

Closing a project or AVEVA Bocad itself is combined with a safety query. Besides the query there are two additional options; Restart with current phase/main view and Restart with current additional views .

With the help of the option Clear up deleted elements you can finally remove deleted elements (such as members, bolts, etc.) from the database. This option is deactivated by default. It should be activated as long as the project is in the design phase. Thus you avoid the unnecessary growth of the file boc3db . When starting with marking, however, this option should be deactivated because the clearing of deleted elements refers consequently to the entire model including the mark numbers and drawings. If e.g. you delete members after the generation of drawings and the project has been closed with clearance, you will not find the drawings concerning the deleted member because AVEVA Bocad cannot find any members belonging to the drawing. The activated option Restart with current phase/main view will automatically open the last active phase and main view when starting again the relevant project. If you do not activate this option when saving the project, you will receive the query to select the phase from a list of existing phases when starting again the program. Afterwards a main view has to be selected from a list of all existing planes.

13.4

Behaviour in case of program crash

13.4.1 Diagnosis and terminating the program A program crash can become noticeable in several ways. The program may terminate with an error message so that it is no longer controllable, but it may also happen that the program is deadlocked and does no longer respond to entries. It may also occur that uncompleted and ragged windows will be represented. Another typical symptom is when you can no longer move windows. You can terminate a blocked program via the task manager of windows. It can be opened the key combination ++ simultaneously, then selecting the Task-Manager in the with opening window. During a program crash you will normally see the entry 'no response' in the column Status. You can terminate the program by clicking the button Close task.

13.4.2 New start of the program with latest backup In case of a crash while working on a project, the project data may be damaged. AVEVA Bocad will inform you about this with the message 'P roject is damag ed - Continue a nyway? ' If this message does not appear you can continue designing in the project without any problems. Otherwise you should use a secure backup of the project.

13.4.3 Loading the last backup First of all, quit AVEVA Bocad in order to restore a backup of the project. Next, open the directory of the damaged project in the Windows-Explorer and carry out the following steps. Project directory (1) Directory with damaged database: Rename with right mouse click on it (e.g. boc3db.bck) (2) Backup directory: Copy with right mouse click, insert below the project directory and rename the copied directory boc3db. (3) New database directory based on the backup.

Start AVEVA Bocad again after carrying out those steps. If you open there the project you will have access to the project data in the recently established directory \boc3db and thus to a correct data version. If you use external backups, e.g. backups on DVD, DAT tape or on a network server, you can also use those backups as a current and correct data basis after a program crash.

CHAPTER 14

14 Phases

14.1

Overview

In AVEVA Bocad you have the possibility to divide a construction. This can meet several demands; e.g. the construction shall be divided into constructional sections which shall be produced and delivered at different times. In this case you have to establish so many phases as the number of constructional sections and link all members, bolts, seams and other elements to them. Later you can establish and sort parts lists and production drawings classified by phases. Another case of application is the division of the construction into different sections, as e.g. framework and facade. Here you have as well the advantage that you can adapt and output the manufacturing documentation individually to each section.
