Davidson (ed.), Models for Computer Aided Tolerancing in Design and Manufacturing, 2 35 – 244. © 2007 Springer. 236 J. Dufaure, D. Teissandier and G. Debarbouille al, 1993], [Fleming, 1987], [Roy et al, 1999] the computation is realized using operations on polyhedrons which represent deviation and clearance domains. An other approach [Ballu et al, 1999] uses surface graph to choose type of the geometric specifications. In this paper we do not present a new computation or description tool of the geometric specification. We present a framework to allow designers to represent functional and geometric requirements at any stages of the design process. Moreover we focus on the influence of the standard component integration on the tolerancing schema of the product. The integration of standard components introduces new geometric requirements on the product. These geometric requirements represent the respect of the mo...
