Assembly features for mechanical product data

This paper deals with a representation of assembly features. Modeling the product at each stage of they assembly process, describing part´s faces, assessing accessibility, and modeling technological information make the series of steps that distinguish our model from the ones found in the literature. Such a representation also greatly contributes to the designing of a system that includes the various stages of the product elaboration. To reach our goal, we generated three levels of features pertaining to faces, parts and subassemblies
