Command input:
ath_bar_use
With this routine you can apply bar assemblies in the drawing. A bar assembly consists of one or more components and can be used two dimensionally (as a section) or also three dimensionally (as an extrusion).
Dialog box Apply bar assembly
db_ath_bar_use
A description of the dialog box sections Selection and the graphical preview can be found in the Chapter Object selection.
Dialog box section Apply
You mark an option button in order to be able to realize the desired function.
The marked function is executed after clicking OK.
After clicking OK the dialog box is closed and the following occurs:
Input request
[Object Mode]
Select axis or [Points/Multiple/?]:
Select a system axis (line, polyline segment, circular arc, null bar or bar) with the mouse.
Select Option Points to specify the start and end points of the axis.
Use the Option Multiple to select several lines. This option is recommended, for example, to set several glazings on carrier profiles (bars). The options for changing the orientation are not shown according to this option.
With the option ? you call the help.
Lines or polylines with only one segment are deleted once the bar has been generated.
If you select a polyline with several segments, the bar is only produced for the selected segment, the polyline is not deleted.
If you apply the bar assembly to an ATHENA axis containing nodes (refer also to Chapter Define nodes), the input request is extended as follows:
Axis [Complete/Segments/?] <Complete>:
You confirm the default <Complete> to create the assembly in the full length on the selected axis.
You select the option Segments to interrupt the assembly at the node points.
After selecting an axis you can determine the orientation of the bar.
Option Points
[Point Mode]
Specify the axis start point or [Object/?]:
Use the mouse or enter co-ordinates to specify the axis start point.
Choose the option Objects when you want to select an axis.
Specify the axis end point or [Undo/Object/?]:
Use the mouse or enter co-ordinates to specify the axis end point.
You select the option Undo to start the point entry anew.
Choose the option Objects when you want to select an axis.
Option Multiple
[Multiple Mode]
Select objects:
Select several system axes (lines, polyline segments, circular arcs, null bars or bars) with the mouse.
Press the Enter key to terminate the object selection.
After the axis or the second point has been chosen, you see:
Bar orientation [Mirror/ Rotate/ surfaceAXis/ surfaceMiddle/ rotationAngle/ Point/ ?]:
Choose an option to change the bar alignment.
Choose the option Mirror to mirror the bar.
Choose the option Rotate to rotate the bar in 90° steps.
Choose one of the following options.
Option surfaceAxis
Select axis or surface or [Points/?]:
Use the mouse to choose an axis or surface to align the bar in the same orientation.
Choose the option Points to specify an axis by entering two points.
Option surfaceMedian
Select first axis or surface or [Points/?]:
Use the mouse to choose the first axis or surface.
Select second axis or plane or [Points/?]:
Use the mouse to choose the second axis or surface.
The bar is aligned along the bisecting angle of the defined surface. With this option you can for example align mullions in pyramid roofs.
Option rotateDegrees
Specify rotation angle or [?]:
Enter a rotation angle.
Option Point
Specify point on the weather side or [?]:
Use the mouse to specify a point on the weather side.
After terminating the command by pressing the Enter key, the input request appears again.
[Object Mode]
Select axis or [Points/?]:
Thus you can assign the bar assembly to further axes until you terminate the function by pressing the Enter key.
Attach
Applies the selected bar assembly to a one or more ATHENA axes (null bars). These arise either by executing Analysis of axis model or by detaching bar assemblies.
With Attach you can only assign bar assemblies to those ATHENA axes which have not yet had any bar assemblies assigned to them or for which the bar assemblies have been detached.
After clicking OK the dialog box is closed and the following occurs:
Input request
Select objects:
You select single axes with the mouse or you select a range with crosses in order to assign this bar assembly to all axes having no assignment.
After execution of the function the output of the number of changed objects follows.
Detach
Deletes the assembly-specific properties of a bar. A null bar is produced by the detachment. A null bar only possesses information on position/orientation, dihedral angle and cutting.
After clicking OK the dialog box is closed and the following occurs:
Input request
Select objects:
You select the bars to be detached with the mouse or you cross a range to detach all axes assigned with the current bar assembly.
To detach a number of the same types of bars in one operational step, you select first the bar assembly to be detached from the pick list or use Object < to make it the current assembly.
Update
Implements changes to the assembly on the selected bars. You first select the bar assembly to be updated from the pick list or use Object < to make it the current assembly.
Only bars can be updated which match the current selection.
After clicking OK the dialog box is closed and the following occurs:
Input request
Select objects:
You select the bars to be updated with the mouse or you select a range with crosses to update all axes assigned with the current bar assembly.
Insert section
Inserts the marked assembly as 2D section into the current UCS of the drawing.
After clicking OK the dialog box is closed and the following occurs:
Input request
Option Point
Specify insertion point or [Object]:
Use the mouse or enter co-ordinates to specify the insertion point of the cross-section.
Select the Option Object to attach one or more bar cross-sections to existing bar cross-sections.
Specify rotated angle<0>:
Enter a rotation angle. Press the Enter key to accept the default angle of 0°.
Option Object
Select bar cross-section or [Point/?]:
Select an existing bar cross-section to attach the bar cross-section.
You should use this option, for example, to attach glazing to cross sections of existing carrier profiles.
The cross sections are inserted with their insertion point on the Glazing axis of the existing profile section. If none has been defined, the base point of the profile section is used.
