Mark, I have gotten your email. I have a few comments for you but all of your emails keep getting bounced back to me. I assume you are subscribed to this list. Have you figured out how to post to it?

| | A comprehensive LDraw object model

There is currently a discussion brewing on developing some LDraw frameworks that would make it easy for programmers (even me!) to write LDraw applications in Java, c++, python, and perl. Check it out here: (URL) here is a template of the object (...) (23 years ago, 12-Feb-02, to lugnet.cad.dev.mac)

I had to close that post before I could mention where all that discussion was going. Briefly, I have been trying from the start to design BrickDraw3D's C++ classes to separate geometry and graphics from the application framework (in this case (...) (23 years ago, 11-Feb-02, to lugnet.cad.dev.mac)

I was thinking of friction as a simple on/off property: connections with friction only move during construction, whereas connections without are free to move under gravity or inertia or other forces during animation of the final model.
