Adding a Catalog Beam Pattern | |
| |
-
To create a beam pattern from one of the standard beam shape catalogs, perform
the following steps:
-
From the Catalog Beam Pattern dialog box, to
select source, click Catalog
.
While editing multiple structure features, you can click
for different shapes of different members. - From Standard, select the desired catalog.
-
From Shape, select a beam shape.
Available selections depend on your Catalog selection.
- From Size, select the beam size.
-
From the Catalog Beam Pattern dialog box, to
select source, click Catalog
-
To create a catalog beam using a cross section defined by an object type,
perform the following steps:
-
In the Catalog Beam Pattern dialog box, to select
source, click Object Type
.
-
Click
and
select an object type from the list of imported object types.
Notes:- Import an object type before creating the member. You can import an existing object type or create a new object type. For more information, see Building and Civil Assemblies User's Guide: Defining Object Type.
- To undefine the object type, you can click
.
-
Click
to
display the graphic help of the object type.
- In the Size list, select the required size for the beam.
The out of the box object types are found at Startup\Structure\ObjectTypes.
To install additional content, select Install Optional Content Now.
The SDD_DSA_Object_Type.3dxml file (for the DSA collection corresponding to the AISC standard) makes all the shapes available with a single import. The best practice is to import the 3dxml files with the option As Reference.
-
In the Catalog Beam Pattern dialog box, to select
source, click Object Type
-
To determine beam pattern location, from Create Mode,
click one of the following:
Option Description Single 
Inserts a beam pattern relative to only the selected segments. Along gridline 
Inserts beam patterns relative to all similar segments along the gridline of the selected segments. All in the story 
Inserts beam patterns relative to all segments in the same story as the selected segments. Above and below 
Inserts beam patterns relative to all similar segments above and below the selected segments. All in the building 
Inserts beam patterns relative to all similar segments in the structural grid. -
To change the zero angle orientation for the beams by 90 degrees, in the
Catalog Beam Pattern dialog box, click either:
- Snap Rotation
Counterclockwise
- Snap Rotation Clockwise
- Snap Rotation
Counterclockwise
-
From Spacing, choose either:
Option Description Count 
Sets the specific number of beams to place and has the system automatically determine the spacing. To complete the selection, enter in Count the number of equally spaced beams.
- To add a member at one end, select the Add member at 1 end checkbox.
- To add a member at another end, select the Add beam at end 2 check box.
Spacing 
Sets the spacing between the beams and has the system determine the number of beams to place in the beam pattern. - In the 3D area, in the value box, enter the spacing.
- To create a pattern with the end spacing less than half the entered spacing distance, select the Reduce spacing at end check box.
- To add member at one end, select the Add member at 1 end checkbox.
- To add a member at another end, select the Add beam at end 2 check box.
-
To determine the orientation, click one of the following:
Option Description Perpendicular 
Places beams perpendicular to the first selected grid segment. Parallel to End 1 
Places beams parallel to a line between the start of the first selected grid segment and the start of the second grid segment. Parallel to End 2 
Places beams parallel to a line between the end of the first selected grid segment and the end of the second grid segment. End 1 & 2 
Places beams by interpolation between the direction of the two ends. -
