CAD system has been widely used in engineering design staff because of their advantages. But it can only deal with graphics geometry information, the actual meaning truly works defined graphical topology and parameter binding information are abandoned. In order to retain more of the graphical information and allow engineers to draw chamber' s graphics more easily, it which based on the characteristics of the mining CAD drawings analyzed the parameters of the chamber graph and implemented chamber graph automatic drawing system by calling mining CAD system' s interface. The system could automatically generated 2D and 3D graphics according to user' s input parameters,which greatly reduces the workload and improves design efficiency. It' s also conducive to the further development of computer-aided design.%CAD系统因其本身具有许多长处,得到了工程设计人员的广泛使用.但它只能处理图形的几何信息,真正具有工程实际意义的图形拓扑信息和参数约束信息均被抛弃了.为了保留更多的图形信息以及让工程设计人员更方便地进行硐室图形的绘制,文中根据采矿CAD图形的特点,把要绘制的硐室图形进行参数化分析,并通过编程调用采矿CAD的接口实现了硐室图形的自动绘制系统.此系统能根据用户输入的参数自动生成硐室的二维和三维图形,这大大减少了设计人员的工作量,提高了设计效率,也有利于计算机辅助设计的进一步发展.
