Summary
Applies a dimensional constraint to a selected object or converts an associative
dimension to a dimensional constraint.
NOTE The L option (last object drawn) is not allowed in the DIMCONSTRAINT
command as the constraint behavior is dependent on where you pick the object.
The following table outlines the valid constraint points for an object.
Valid Constraint PointsObjects
