Joint Constraints

Form:  Assign/Define Constraints

A constraint is a group of joints that are connected. When a constraint is assigned to a joint, the joint becomes a part of the constraint and connects to other joints in the constraint. Constraints can be pre-defined using the Advanced > Define > Joint Constraints command, or they can be defined while assigning them to joints.

Note: More than one constraint can be assigned to a joint. The program will automatically resolve competing constraints. However, do this with caution. Large parts of the model could be rigidly connected together, which may over-constrain (over-stiffen) the structure.

  1. Select a set of joints that will be part of the same constraint. Other types of objects may be selected because they will not be affected by this assignment.

  2. Click the Advanced > Assign > Joints > Constraints command to access the Assign/Define Constraints form.
