Vertex Attributes: Restraint

Description

Assigns translational and rotational restraints to selected vertices.

When the geometry is meshed, the node created at the vertex will inherit the restraint attribute (see Node Attributes: Restraint).

Vertex restraint attributes are interpolated along edges during meshing, if the edge type is set to interpolated (see Edge Attributes: Type).

Restraint attributes are freedom case dependent.

Dialog

Translational/Rotational X / Y / Z

The three translational and three rotational degrees of freedom. See Node Attributes: Restraint for more details.

Restraint Shortcuts

See Node Attributes: Restraint for more details.

Coordinate System

The coordinate system (UCS) in which the restraints are defined.

The restraint attribute remains associated with the UCS in which it is defined. Subsequent changes to the UCS will change the resulting restraint directions.

Units

Translational enforced restraints are in the length units of the model (e.g., m, in).

Rotational enforced restraints are in degrees.
