Quickly Build High-quality Surface by Using CATIA in Reverse Engineering

In reverse engineering,the point cloud data is obtained through the measurement to product sample by using laser measurement machine.The point cloud can reflect the product shape by creation of the small triangular grid surface after carrying necessary process to the cloud point。According to these point cloud data to build high quality surface rapidly by CATIA.In construction,this paper discusses the following questions including how to disassemble topology of the product,analyzing the connection relations between surfaces,smoothness of the rapid build surface check and distance error between the s point cloud data,product function and technology check and so on.During the surface fitting by using strong fitting tool of CATIA software,to create smoothness surfaces under the permitted distance error by adjusting the surface degree and segments.
