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.
