An advanced 3D product creation package... Mechanical Design Products allows the user to create parts in a highly productive and intuitive environment, to enrich existing mechanical part design with wireframe and basic surface features and then easily establish mechanical assembly constraints, automatically positions parts and checks assembly consistency. Advanced Drafting capabilities are also provided through the associative drawing generation from 3D part and assembly designs. Mechanical Design products can address 2D design and drawing production requirements with a stand-alone state-of-the-art 2D tool Interactive Drafting 1 (ID1).
