We propose you to read our whitepaper How to Express Design Intent in Rhino 3D. Part I. Assembly Design and Kinematic Simulation.
It presents the functionality of Rhino Assembly, the first Driving Dimensions plug-in for Rhino, and describes the conceptual ideas behind it. The paper concludes with an outline of our ideas for future products for Rhino.
The paper also includes a mini-tutorial allowing everyone to assemble a simple piston engine in Rhino.
Please put your comments on our paper in this thread.
