I am an engineer (translated NOT an artist;)) working on a study involving modeling bone joints. I have 3-D surfaces of a couple of bones and can easily select out the parts I am interested in with blender. Now the challenge is I want to create surface that is between the two surfaces.
I would like the surface to be made from the normals of each surface pointed at the other with the new surface being located in the middle.
I have tried to extrude each surface and do a boolean but the computer just sits working away forever. This is an imported stl which is obviously very dense so maybe I need to simplify and retry that.
Thanks for any suggestions,
