Hi I'm trying to create ONE solid from all of its faces i.e. I defined, for exemple, all 6 3D faces (or meshes, or edgesurf) composing a cube (not a regular cube, but sort of, with irregular surfaces but all sharing and edges with each other). What I have now, is 6 faces making a perfectly enclosed area, but I wanna Autocad 04 to transform it to one solid, so I can calculate volume, etc... I hope I'm not too unclear (sorry for my English) Thanks in advance!
