| Abstract: | This paper introduces Bottom-up and Top-down technologies of virtual assembly.The advantage of Top-down design is presented by comparing two kinds of methods.Take the design for the connect hinge of subway vehicle as example,the application of Top-down design in CATIA is introduced.Using this design method can achieve the intent of designer more directly and more exactly,and it will shorten the design cycle a lot. |
