Introduction of geometrical contraints modeling in SysML for mechatronic design

In order to take into account geometrical considerations in the early stages of mechatronic design, we propose a SysML extension for geometry: GERTRUDe. This profile, and the developed HMI enable not only to easily specify some geometrical requirements but also to model components of physical architectures, with a simplified geometry, and to specify some geometrical constraints, based on the TTRS theory, in order to position them relatively to each other.
