I have a model of a thing, it’s “egg shaped” and it’s a “solid” (no interior) and all I have is a bunch of vertexes describing the outer shell. It’s not two-sided. There is no interior. When I need to do is end up with a shell (sphere) that has a thickness, and one that I can poke circular holes through. Let’s say my pre-existing shell has a bunch of hexagons on it… (or even triangles). The holes I want to punch through the solid are per-hexagon. That is, I want to select the vertices making up a single hexagon, then “punch a hole through the shell” in that shape. I’m having a doozy of a time trying to figure out how to take the original mesh and make a two-sided shell with a given thickness, and then how to punch the holes through the shell. Any advice?
This is what I’m talking about, but it has no thickness:
