I try to figure out something: Example. I make a shape of, let’s say… a jacket. And I want to mask-out a collar to have it as a separate tool. So I paint a mask in the shape of a collar on the jacket, then I select ‘hide pt’ and then ‘delete hidden’ so that I have just the shape of the collar. OK. But it has no thickness. How can I give some thickness to this shape? It is just a shell now. Thanks.
After doing that, your next step would be ‘Tool>Subtool>Extract’. Set your desired thickness, hit ‘Extract’ button then hit ‘Accept’ button if your happy with the thickness.
Excellent, thank you!
