【Abstract】 A CAD system for 3D hydraulic pipe laying developed on personal computer is presented. A drawing library for hydraulic components is established adopting surface modeling and parametric drawing, and it is managed by a menu-driven system together with coordinates. The design and simulated assembly of 3D pipe laying can then realized.2D engineering drawings and 3D assembly drawings of the hydraulic system can also generated.更多还原
