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 headerType of dataValue example or enum definitionRequired valueDescription

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

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).
