Lock a form profile to constrain its relationship to other profiles in the form.
When you lock profiles, the form maintains a relationship between the top and bottom profiles, and is limited in the way it can be manipulated. When you manipulate one locked profile, it affects the other, and therefore, the entire shape. For example, if you select the top profile and lock it, all the profiles take on the shape of the top profile.
When profiles are unlocked, the form can be manipulated in any way.

The selected profile controls the locked shape.
All form profiles are locked, including any additional profiles that may have been added after a previous unlocking of the profile.
