【Abstract】 Currently, machine parts parametrized CAD systems are available in the market. Some of them may be powerful but they are enormous in volume, high in price, and awaiting renewal of computer technique. Some of them are draft-oriented, incapable of drawing in detail. Based on predecessors’work and up to date database-interface software, we develop the parametrized machine parts CAD system with computation, drawing, and design integrated. It is applicable to manufacturing engineering.更多还原
