I've just done my ultimate simulation taking hint to Charles' post.
In the attached 7z file you find the creo files and a little avi.
The thing works but I don't comprehend exactly how.
Meanwhile I don't know how it interprets the enforced angular displacement: degrees, rads, mm, an arc expressed into mm...boh...
I've tried to express the time dependency of the constraints as Charles has done, but it has not worked. Nothing moved.
Furthermore I've changed the surface where I've put the imposed rotation: the external cylindrical one of the hole/pin.
Again, I can't understand why tensions born around the surface utilized for the displacement.
