Constraints can be used in block definitions, resulting in dynamic blocks. You
can control the size and shape of dynamic blocks directly from within the
drawing. For more information, see Add Constraints to Dynamic Blocks.
Remove or Relax Constraints
There are two ways to cancel the effects of constraints when you need to make
design changes:
■ Delete the constraints individually and later apply new constraints. While
the cursor hovers over a geometric constraint icon, you can use the Delete
key or the shortcut menu to delete the constraint.
■ Relax the constraints temporarily on selected objects to make the changes.
With a grip selected or when you specify options during an editing
command, tap the Shift key to alternate between relaxing constraints and
maintaining constraints.
Relaxed constraints are not maintained during editing. Constraints are restored
automatically if possible when the editing process is complete. Constraints
that are no longer valid are removed.
NOTE The DELCONSTRAINT command deletes all geometric and dimensional
constraints from an object.
