StructuralCurveConnection Class

[This is preliminary documentation and is subject to change.]

Defines 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. The 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.
