I get complex models from my customers and I prepare them for 3D-printing in a external program. The out-put is a hollow object, one mesh of the outside and one inside.
Now my 3DS printer doesn’t recognise this object as being hollow and likes to print it solid. I need to add a hole, a connection between the two meshes.
Is there a way to do this easily within Rhino-mac? Ofcourse I could go back to Nurbs again and do it but this would take time and calculation power. So my question would refer to the mesh commands.
