CompositeShapeDef

Composite Shape Definition

Composite Shape definition is required when the cross-section type in StructuralCrossSection sheet is set as "General".
For manufactured types of a cross-section, is Composite Shape Definition is optional, offering the possibility to share detailed shape definition, for better classification of the profile.

Specification in excel:

Name of the column header
Type of data
Value example or enum definition
Required value
Description
Name
String
GEN_1
yes
Name of the profile from the StructuralCrossSection object sheet
Material name #
String
MAT_1
yes, if polygon is not opening
Name reference to the existing StructuralMaterial object
Polygon contour #
String
-75.0; 105.0| -175.0; 5.0| 175.0; 5.0| 75.0; 105.0
yes (at least one)
This attribute is used to define the cross-section geometry as a polygon contour.
One cross-section shape can consist of more polygons.
Openings contour are defined clockwise.
Common polygons counterclockwise.
The format of the data is:
y1; z1
Id
String
39f238a5-01d0-45cf-a2eb-958170fd4f39
no
Unique attribute designation

Notes

The symbol "#" means indexing of the name columns, depends on how many polygons is used, starts from 1
The contour defined clockwise is opening
The contour defined counter clockwise is polygon of the general cross-section (relation between LCS and counter clockwise direction is shown below)
Each polygon has a defined material which is name reference to existing material in StructuralMaterial sheet
  • The opening has no material definition
  • Each polygon contour has to be closed
  • The set of all polygons and openings defines one general cross-section (one row in the Excel table)
  • The number of polygons is limited to 99. The definition of the general shape has to consist of at least one polygon which is not the opening.
  • CompositeShapeDef example with opening is shown below. A,B,C,D are defining the contour of cross-section (counter clockwise polygon) and E,F,K,L are defining the opening (clockwise polygon).
