摘    要：探讨了在AutoCAD平台上进行三维参数绘图应用软件开发的技术，即根据空间零件的结构特点，将零件分解为一定数目的三维基本实体图元，进而对这些图元进行加、减、并、交布尔运算，建立零件实体模型．从实体模型中，提取轮廓几何信息和剖面几何信息并作定向投影处理，可得到零件的各个视图(包括剖视图)．其设计方法易于理解，易于实现，对三维参数化绘图应用软件的开发具有一定的参考价值．

Abstract: This paper discussed the development technology of 3-dimension(3D) parametric drawing application software and provided an example for designing application. According to parts′construction, a part is disassembled into some basis of 3D solid drawing elements and then are these elements combined into 3D solid model by using Boew operation. Then profile view and abstracting necessary message on solid model would produce cutaway view. This designing idea has some value to 3D parametric drawing application software for reference due to its understandable and realizable property.
