在综合考虑参数化零件图的复制和对装配图中零件图的计算机识别的基础上 ,构造了装配图的参数化修改模型 ;结合基于深度测试的装配消隐算法阐述了一种基于参数化零件图的二维装配图修改技术。实际应用结果表明 ,由此技术生成的装配图可进行参数化尺寸驱动修改 ,并且在装配图的构建过程中也可动态尺寸驱动修改零件图 。

Based on analyzing the method of copying parametric part drawing and the method of recognizing different part drawing in a assembly drawing, a kind of model on modifying assembly drawing is constructed. Combining with the calculating method of hide based on depth method measure, the technology of modifying 2D assembly drawing based on parametric part drawing is presented. The application to this technology testified: not only the assembly drawing can be dimensionally driven, but the part drawing can be dimensionally driven during the course of constructing assembly drawings.
