StructuralCurveEdge

Internal edge

Internal edge (StructuralCurveEdge) is an object within a 2D Member (StructuralSurfaceMember) on which the line force (StructuralCurveAction) can act. StructuralCurveEdge can be placed on StructuralSurfaceMemberRegion, but the relation is always to 2D member (StructuralSurfaceMember) where StructuralSurfaceMemberRegion is placed.

If StructuralCurveEdge does not geometrically fit to the StructuralSurfaceMember it is assigned to, it is considered a logically invalid input. Cases like this one have to be solved by validation during the import of excel data to the specific software. The validation has to be implemented together with the import/export of SAF.

Specification in the excel

Name of the column header	Type of data	Value example or enum definition	Required value	Description
Name	String	IE1	yes	Human readable unique name of the internal edge
2D member	String	S2	yes	The name of the StructuralSurfaceMember (plate, wall) on which the internal edge is placed
Nodes	String	N1; N2	yes	All nodes that belong to the curve edge and define its geometric shape. The names of the nodes are separated by ; (semicolon) and space. The order of the nodes has to be from beginning to end.
Segments	String	Line; Circular Arc; Bezier; Parabolic arc; Spline	yes	Defines the shape of the curve between two next nodes. Supported strings are: Line; Circular Arc; Bezier; Parabolic arc; Spline. The names are separated by ; (semicolon) and space. Internal edge consisting of multiple segments follows rule defined in Geometry
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	36606732-25e0-4fd7-ae35-bb8cb1bdcf46	no	Unique attribute designation
