Libraries of standard parts are featuring 2D and 3D mechanical engineering libraries like bearings, nuts, screws, HASCO elements, FESTO elements, welding and surface symbols, electrical, electronical, pneumatic, hydraulic components etc. Most of them are both for "OneSpace Modeling" and "OneSpace Drafting" and some of them are only for Drafting. We support standards like DIN/ISO, ANSI and GOST. The libraries are open and therefore it is easy to implement any other local standards.
