Quote - I think the script will be generating .cr2 and .obj files for the chain ... shouldn't [be] a problem with Python

You're right, it isn't a problem.

One thing to think about is that if you're generating the chain in place, does it actually need to be a figure ?
A chain figure is handy for lengths lying around, i.e. not hanging between two points for which you might as well just have a prop (and regenerate if the end points move).
