［提要］通過ObjectARX接口，采用Visual C++語言對AutoCAD進行二次開發(fā)，擴展了AutoCAD的三維實體功能，在其中加入描述復(fù)雜構(gòu)件的幾何和結(jié)構(gòu)信息，并重載了自定義實體的顯示、布爾運算和表面近似展開等操作，從而解決了彎扭形構(gòu)件和彎扭變截面構(gòu)件的三維實體建模和施工圖繪制問題。系統(tǒng)已成功地運用于2008年北京奧運會主體育場的實體建模和施工圖繪制。

Manufacture Drawing Software System for Benttorsional Bar Based on 3D Solid Model/ Chang Zhiguo, Yang Huizhu, Zhang Qilin(Building Engineering Department, Tongji University, Shanghai 200092,China)
Abstract:A manufacture drawing system is developed in Visual C++ programming la
nguage by using the SDK of AutoCAD. The custom entity, which includes the geomet
rical 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 benttorsional 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.
Keywords:benttorsional bar; 3D solid model; manufacture drawings
