Unfortunately as far as I know, our joint/grip system was never documented. I have some joint files around somewhere, but I'll have to dig for them. It might be easier to just read the source code and recreate an input. > I'd appreciate if someone could explain how this command is used or > point me to some resource regarding its use. The general idea is that you create 'grip' objects in your model (akin to creating rigging objects in other CAD systems) and then you can move geometry using the joint command. The joint command takes a simple text input file that describes the ranges of motion that are allowed for a given geometry association. At least, that's my vague recollection. I've not dealt with that system nor code related to it in several years. When in doubt, consult the source code. ;) Cheers!
