三维CAD模型重建是逆向工程中的关键环节，在逆向设计中起到至关重要的作用。在运用Geomagic Studio软件进行点云处理、错误修复和曲面生成的基础上，重点讨论了曲面阶段的精确曲面重构和参数化曲面重构两种不同的曲面重构方法，并对同一种模型进行重构和误差分析。精确曲面重构方法可保证模型数据的完整性与精确性，从而生成高质量的模型；参数化曲面重构方法通过参数转换功能将初始曲面导入SolidWorks软件中进行编辑，最后得到参数化模型。实际应用中可结合这两种方法各自特点及优势，高效优质地构建CAD曲面模型。

CAD model reconstruction is the key technique in reverse engineering,and plays a very important role in the recon-struction of the reverse technology.Based on some methods of Geomagic Studio about processing point cloud,fill holes and surface reconstruction,two different ways of dealing methods in shape and fashion module in the surface phase reconstruction and toler-ance analysis are investigated thoroughly through the same case studies.Shape method could ensure the integrity and the accuracy of the model data to generate high quality mode.Fashion module method transfers the primary surfaces to SolidWorks package through parametric exchange function to be compiled,and a parametric model is obtained.Based on the advantage and application occasion of the two methods,the surface can be completed high-rate.
