Through connecting virtual reality (VR) technique into CAD environment, and introducing human to conceptual design loop, a kind of VR based object oriented modeling is given, a VR based system VR PS is constructed.

• 把虚拟现实技术与CAD设计环境结合起来，通过将人引入概念设计回路，提出了基于约束的面向对象建模方法，形成了基于虚拟现实技术的原型设计系统VR?PS，并探讨了系统的组成和实施机理。
