Abstract
All CAx (Computer Aided Everything) systems give their contribute to design activities; in particular CAD systems mould the geometric characteristics of parts (features) through solids or surface entities and build up the virtual assembly of the same parts. In this context, a top-down approach and the use of a structure called “skeleton” encourage an integrated management of the whole design. The skeleton carries out the control and integration of all developing parts; it allows defining the way and the criteria in order to organize and realize the modeling work; moreover, it assures coherence between the formerly assigned tasks to different work groups. The present work deals with parametric-variational properties of CAD associative systems and gives evidence to advanced procedures to control features. The work proposes a new methodology for the modeling development of a complex product using CAD systems and presents an application of the same methodology to the design of car body components developed in ELASIS S.C.p.A.
