CompositeShapeDef
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.
Name of the column header | Type of data | Value example or enum definition | Required value | Description |
---|---|---|---|---|
Name | String | GEN_1 | yes | |
Material name # | String | MAT_1 | yes, if polygon is not opening | |
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 |
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).
