StructuralSurfaceMemberRegion

Region of different plate thickness

This object defines particular areas of the StructuralSurfaceMember with different thicknesses.

Specification in the excel:

Name of the column header	Type of data	Value example or enum definition	Required value	Description
Name	String	R1	yes	Human readable unique name of the object
Material	String	MAT_1	yes	The name reference to the existing, valid name of the StructuralMaterial object.
Thickness [mm]	Double	200	yes	The thickness of the StructuralSurfaceMemberRegion Thickness is considered in total.
System plane at	Enum	Bottom Centre Top	yes	Defines position of the system plane (local x and y-axis) of the StructuralSurfaceMemberRegion and determines the alignment of the region. Top: the StructuralSurfaceMemberRegion is aligned with the top surface of the StructuralSurfaceMember, Bottom: it is aligned with the bottom surface.
2D Member	String	S13	yes	The name of the StructuralSurfaceMember to which is the region situated.
Nodes	String	N81; N263; N659; N660	yes	All nodes that belong to StructuralSurfaceMemberRegion and define its geometric shape. The names of the nodes are separated by ; (semicolon) and space.
Edges	String	Line; Line; Line; Line	yes	Defines shape of the curve between two next nodes. Supported strings are: Line; Bezier; Circular Arc; Parabolic arc; Spline; Circle and Point; Circle by 3 points. The names are separated by ; (semicolon) and space.
Eccentricity ez [mm]	Double	-125	yes	The eccentricity of the slab may be input. Eccentricity is measured from the system plane – local x and y-axis and the direction is in local z-axis.
Area [m2]	Double	1.485	no	The value of the surface area of the StructuralSurfaceMemberRegion
Parent ID	String	67b35d84-3d04-47aa-aa4a-dc1263982320	no	Is filled for objects created be dividing curved geometry to series of straight line objects. Parent ID will ensure that curved edge is imported as straight parts to nonsupporting application, and back to original supporting application as curved geometry. To ensure successful round trip of segmented objects and their related objects, Parent ID needs to be present in both directions.
Id	String	39f238a5-01d0-45cf-a2eb-958170fd4f39	no	Unique attribute designation
