Aiming at the independent geometric reference models of IGES surfaces for housing-type components, basing on the Pro/E, authors proposed the method of using the "exterior copy geometry" technology to extract references for surface reconstruction. The top down design ideas are adopted to break down original complex model into several components. After defining the modeling datum and father-son relationship, copy geometry is applied to reconstruct each component. Then all the part models are assembled by "exterior copy geometry" technology in the way of coordinate system superposition. And finally a 3D modeling of complex surface part is reconstructed. The No.10 coupler in CHR3 train is taken as a case study. Extracting geometry reference data from IGES model, without any parametric features, then these data are used to do parametric modeling in Pro/E in order to make them support variability design. Cooperating Pro/E with Imageware, quality of surface reconstructed is analyzed and evaluated. The above method provides an efficient solution for complex parts parameterization modeling and evaluation.
