摘　　要：为了利用CAD系统对逆向重建模型展开创新设计,设计了基于XML逆向重建模型表示。采用CSG/B-rep混合表达的方式表示了重建的实体特征模型。建立了该模型基于XML表示的数据文件,通过CAD系统二次开发实现了XML数据文件的解析,从而在CAD系统中生成了该模型。实验的结果表明该方法能将重建模型的特征信息和约束信息完整地传递到CAD系统中,实现了逆向重建结果与CAD系统的紧密集成,可有效支持基于原型的创新设计。For innovative redesign of the reverse reconstructed model by making use of modern CAD system,a new XML based reconstructed model representation is designed.The reconstructed model was expressed as hybrid CSG/B-rep mode.A XML-based data file depending on the hybrid model was established which could be parsed in CAD systems.After second development of CAD systems,the file was imported and feature-based CAD model was rebuilt.The experimental result shows that this XML based file can completely transfer the feature information and constraint information into the CAD system.It achieves the integration between the reverse reconstruction and CAD systems which can support innovative redesign effectively.
