From the developer:
You can enable collision detection and realistic physics for your 3d models by simply importing them to your 3D Rad project (no coding!). These 'bodies' can then be combined visually with working joints, wheels, springs, forces and even airfoils, to create any sort of system (cars, aircraft, ragdolls, machines).
