In order to prove this method is applicable not only in simple graphic drawing but also in complicated machine parts design, through building up gear mathematic model, researching on gear design in routine way, and with the help of opengl, author realized the gear real time collaborative design with great success, in which 3-demensions solid model as well as 2-demensions drawing are available
为了证明这种系统不但能实现简单图形的协同绘制，同样能实现复杂零件的实时协同设计，论文还以齿轮为例，具体研究了机械零件网上实时协同参数化设计的实现。在对齿轮的研究中，不但实现了齿轮的二维图形的实时生成，而且也实现了三维模型的实时生成，充分证明了这种实时协同设计方法的可行性和优越性。
