StructuralCurveConnection

Supports on 1D members

Object definition for a line support on a 1D member (StructuralCurveMember) or on a rib (StructuralCurveMemberRib). The support can be defined along the entire length of an edge or on its part only. This support is defined by six independent parameters. Each parameter defines the constraint in one direction: translation in X, Y, Z axis and rotation around the same axes. The parameters are the same as for line support on 2D memeber edge support (StructuralEdgeConnection).

ux
Enum
Free
Rigid
Flexible
Compression only
Tension only
yes
Translation in X direction.
Free - That is it imposes no constraint in the direction. Rigid - The connection in fully rigid in the specified direction. Flexible - The connection is flexible (elastic) in the specified direction. Parameter Flexible can be linear only, non-linearity is not supported. Compression only acts only under compression. If the support gets under tension it stops acting. Tension only support acts only under tension.

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.
