Study on reverse design method of industrial design product

Yang Yan-hon

Abstract

According to the structure characteristics of industrial design product,a method for rapid model reconstruction and accuracy analysis based on Geomagic Studio and CATIA is proposed.Model data is acquired by 3D laser scanner,the data processing and coordinate system alignment is performed in Geomagic Studio,then the surface reconstruction based on curve and surface best fitting modeling based on data point are finished in CATIA.Based on the construction principle of NURBS curve and surface in CATIA,the product 3D digital model is built based on CATIA multiple working table hybrid modeling,and the reconstruction surface fitting accuracy is analyzed.The results show that the method provides a new idea for the product innovation design of industrial design and it has a certain practical value.
