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).
