Technology and application of parametric modeling in reverse engineering

Parametric modeling is a new modeling method formed from a parametric technology based on reverse engineering which can not only extract the original design to construct a more accurate CAD model,but also realize the model parametric modification for innovative design.The conception of the reverse engineering and methodology of reverse parametric modeling were introduced in brief,taking the automobile rearview mirror as an example,Geomagic Studio software is used to deal with the point clouds,and primary surfaces model is simulated by feature recognize.Then the primary surfaces are transferred to Solidworks package through parametric exchange function to be compiled.And a parametric model for automobile rearview mirror is obtained,which provides a valid way for parametric modeling in reverse engineering.
