turning a mesh file inside out?

[gaittec]

I need to know if there is a way to turn a 3d stl mesh file inside out.

Here's my project. Think of a footprint in sand. Scan the foot print. This gives you a negative (reverse) copy of the surface of the foot. Now I need to turn that negative scan inside out so that it is a positive copy of the foot.

I hope this is clear. I will actually be scanning foam impressions of feet and than I want to reverse them inside out so I get a mesh file in stl that is as if I had scanned the actual foot directly.

Please email any answer gaittec@gmail.com

3D scan/cavity

A 3D scan only generates a surface, so you don't have to change anything. You just use the surface to create a 3D solid, rather than an empty cavity.

You can mirror the surface and flip it over as well, but I don't think that is what you are after.
