This paper mainly focuses on modeling and assembling the whole set moulds which are used to produce the sheathing of automobile glass riser by using the powerful function of CATIA in respect of modeling.Speedy conceptual design can be conducted by substantiality modeling system and their requirement and the programming restricts will be bined by the mathematic relation among different ponents in conceptual on features,substantiality modeling and editing capacity help the designers changing and renewing substantiality by way of editing the dimension of substantiality features directly or other geometric editing and constructing techniques. For the sake of optimizing design plan,CAD and CAE can be used simultaneously in designing,calculating analysis and designing can be conducted at the same that the quality of the product can be ensured at the rock bottom.
