Virtual Design is a very important aspect in CAD research and it is widely applied in the design of mechanism.Now many CAD softwares can realize the virtual design of mechanism and simulation of mechanism movement.But its file is bulky and the interaction is weak,so it is difficult to transfer on the web.VRML provides a brand-new thought or method to resolve the problem.The feature of VRML is introduced in this paper and the method and principle of creating static and dynastic virtual model using CAD softwa...
