Find Free Faces
Use the Find tool to find free faces in a group of 3D elements and create shell elements from them.
The free faces that are found are displayed as quad or tria elements. All of the elements created during a find are placed into a component called ^faces which is created by the find faces command.
To avoid confusion, ^faces is deleted (if it exists) and then re-created at the beginning of the find faces function.
The elements that were selected before the find faces function remain selected upon completion of the function.
