Modeling Framework for a Consistent Integration of Geometry Knowledge During Conceptual Design

This paper proposes a modeling framework for a consistent geometrical data link between a system model and a spatial architecture modeling in a 3D computer-aided design (CAD) environment, with a model-based system engineering (MBSE) approach. Our approach, focused on the conceptual design stage, for the evaluation of 3D architecture under physical constraints, aims at improving the system design by ensuring data consistency during collaborative design. This model transformation platform will ensure a seamless geometrical consistency and traceability from the requirements to the further design stages. The theoretical formalization of our approach presents a consistent integration of geometry knowledge all along the conceptual design. Then, the corresponding modeling platform implementation between the developed system modeling language (SysML) geometrical extension and a 3D CAD tool is described before detailing an application on a conveyor case study.
