Hi

I've designed my part and I'm trying to create a mold to thermoroming my part.

I've tried using "Intersect" and get a nice result. But the problem is that it's the wrong face on my part that's the "face" on the mold form, therefore the filling are to big and the measurements isn't right. Is there some way to use the outside surface in the intersect option? or will I have to do it another way? I don't know how to do it.

I've attached the part so you can get an understand of what's the problem
