Risposta:
È possibile utilizzare gli svincoli superficiali, ma è necessario separare la parte sovrapposta con una propria superficie. Overlapping surfaces should be avoided in general and can be checked by the "Model Check" (Tools → Model Check → Overlapping Surfaces). Please watch the video file (see the link below) to see the approach. As an alternative, you can add a "Contact Solid" between two surfaces.
