The near impossibility to understand any of the 3D solid functions? I make 3D solids left and right and have no idea to translate them into Map3D. The "jargon used" for solids involves "rendering", "extrude faces" (wholly cow!), meshes, "faces-and-edges", NURBS (lol, again).
A solid is a solid or a triangulated set of faces, yes? A single face is not a solid, nor are several faces unless they have coincident points (triangles at least, eh? I noticed the meshes are triangles, eh? Review collected by and hosted on G2.com.
