Creating rigid constraints graphically

Rigid constraints can be created using the Sculpt > Constraint operations > Create rigid constraint menu command. The procedure is as follows.

1. Set the cursor mode to Select nodes.
2. Select the nodes that are to form a rigid constraint.
3. Give the Create rigid constraint command.
4. Open the Rigid constraints table and set the type of linkage as required.

Note: This process results in all selected nodes being included in the rigid constraint node list and the highest numbered of these being the primary. The fact that the primary is also represented in the node list is not a problem.
