Jiba,
I was seeing if I could learn a little more of the Blender Python API,
and I came up with this. It's just a demo, but I thought it might be
useful to see if you could integrate it with your import_blender.py or
blender2cal3d.py scripts (I made it with the latter in mind). It makes
setting parameters a little easier.... :-)
Anyway, if it's useful, then great (feel free to use it), if not, then
fine, it was a good learning experience for me. :-)
