This paper proposes a modeling framework for a consistent geometrical data link between a system model and a spatial architecture modeling in a 3D CAD (Computer-aided Design) environment, with a MBSE (Model-Based System Engineering) approach. Our approach, focused on the conceptual design stage, for the evaluation of spatial 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 in Python language between the developed GERTRUDe (Geometrical Extension Related to TTRS Reference for a Unified Design) SysML (System Modeling Language) extension in the PTC integrity Modeler tool and the FreeCAD tool is described before detailing an application on a conveyor case study.
