摘　　要：通过ObjectARX接口,采用Visual C++语言对AutoCAD进行二次开发,扩展了AutoCAD的三维实体功能,在其中加入描述复杂构件的几何和结构信息,并重载了自定义实体的显示、布尔运算和表面近似展开等操作,从而解决了弯扭形构件和弯扭变截面构件的三维实体建模和施工图绘制问题。系统已成功地运用于2008年北京奥运会主体育场的实体建模和施工图绘制。A manufacture drawing system is developed in Visual C ＋ ＋ programming language by using the SDK of AutoCAD. The custom entity, which includes the geometrical and structural information of complex bar, and overloads virtual functions such as viewport draw, bool operate, and surface deploy, are developed to extend the 3D solid functions of AutoCAD. Therefore, the problem of the 3D solid modeling and manufacture drawing for bent-torsional bar can be solved effectively. The software system has been applied to construct the 3D solid model and manufacture drawings for the main stadium of the 2008 Beijing Olympic Games.
