Get Fill of shape as new shape

Hi All!

I have a shape that I need to get kind of the inverse of so I can get a vacuum mold created and can’t quite work it out!



As you can see this is a kind of conical shape. I basically just need the fill of the cone as a shape.

If anyone can help you have my eternal gratitude!

Kind Regards

Matt

Just duplicate the inside faces and then fill the ends, and correct the normals. By doing that, you should have the inverse object of that interior surface. Fairly simple in this case.
