Defining the Working Zone

You can define an area on a surface before performing a modification.

Selected vertices, edges or faces appear in the 3D area. Therefore only these elements can be modified. The other elements are protected and cannot be modified.

Before you begin: Create a 3D shape containing a subdivision surface.
