Feature-based Modelling allows extra meaning to be added to geometry, but lacks the equivalent geometric formalism usually found in computer-aided design (CAD) and Geometric Solid Modelling (GSM) systems. CAD systems have been evolving into constraint-based design environments instead of intent-driven ones where the designer can use whatever manipulation is available in the system without been afraid of messages like "manipulation not permitted". These messages usually restrain the user in order to avoid representation changes and faulty or "unknown" situations. A Design-by-Feature system with a representation validation framework is presented that supports "Design for X", intent-driven modelling, encompasses existing low-level geometric verifications, adds high-level rules to analyse and enrich the design and incorporates operations to assure its correctness. Also it alleviates the designer from specifying each and every geometric detail/relationship (improving productivity).
