基于Geomagic Design X的正逆向混合建模

逆向工程中关于正逆向混合建模的研究在近几年来成为热点。介绍了逆向工程中常用混合建模方法与特点,提出了基于自动特征识别与面片草图的混合建模方法,根据设计意图重新定义设计参数,以Geomagic Design X软件为平台进行实体重构。通过实例获得了可编辑的、基于历史树的CAD数据模型,同时验证了该混合建模的准确性和便捷性。

Forward and Reverse Hybrid Modeling Based on Geomagic Design X

In reverse engineering , the research on the forward and reverse hybrid modeling has become a hot spot in recent years . The methods and characteristics of hybrid modeling commonly seen in reverse engineering are introduced , and a hybrid modeling meth-od is presented based on automatic feature recognition and mesh sketch .Using Geomagic Design X software as a platform for solid re-construction, the design parameters were redefined according to the design intention .The historical tree of Computer Aided Design ( CAD) data model which can be edited was obtained by an example .The accuracy and convenience of the hybrid modeling are verified .
