I must confess to some considerable amount of embarrassment over the figure I attached to a previous post. First the path to the obj file was wrong, and that was a serious blunder on my part. The other point is that whilst the figure worked for me in PP2012, when I tested it in P8 and P6 the cylinder actor was seriously messed up, and 'Point At' caused it to point off to the the side a a very strange angle. There was also a problem with the linkarmbottompin not displaying.

The demands of the silly season kept me from doing any work on the figure until today. I have attached a new version above. It has been tested in P6, P8, and PP2012. I have to admit that the the two fixes I implemented were a bit of a kludge, but at least it seems to be working as desired. I will say more about the fixes later. Note that the figure is still using the original geometry (with a few modifications).

There are still a few changes I would like to make, including using your new geometry, but it now seems to be a working figure.
