Processing product shapes and formalizing the information involved at the interface process between the L and Engineering Analysis activities is essential. Ln this work, a general framework for the definition intermediate model is proposed. The reference shape model is a polyhedral one but it is enriched with a hi level description. The resuIting mixed shape representation allows one to translate sorne of the problem hyp01 and objectives in terms of constraints that must be satisfied during the generation of the intermediate model or in the process, during the generation of the simulation model where performing the engineering an~ Moreover, the relation subsisting between the application of a mechanical criterion and the removal of a shap< domain is higWighted. Ln particular, the formulation of an a posteriori mechanical criterion supporting the transformations is provided.
