I have come across a very strange and rather disturbing problem. I'm trying to rig a model of an engine lift by unbroken-fighter. The model has a hydraulic ram, and it needs to use 'Point At', to operate the ram. This is the sort of thing  many of us will have done before. Two parts 'ram' and 'cylinder' both need to 'Point At' each other. At the moment the engine lift is a collection of props parented to a BODY actor.

I got the ram and cylinder rigged and working correctly in 'Poser Pro 2012' (PP2012).

I then opened the same scene in P6. In P6 the origin is in a different position!?!

WHAT THE F***!!!

How can this be? In the Joint editor In both PP2012 and P6, the Z value for the origin is the same number, but the position of the cross-hair is very different.

All values are in Poser Native Units. In both PP2012 and P6, the Z value is displayed as a different number in the Joint Editor as opposed to the Parameters palette. In the case of P6 the values are close enough to suspect that the difference is due to rounding in the Joint Editor, but in PP2012, rounding would not seem to account for the difference.

Thr cross-hair does accurately represent the effective pivot point in both versions.

Perhaps I'm doing something wrong, perhaps I made some stupid mistake. But if I did not make a mistake, then this looks like a very serious bug in Poser. I'm not sure which version is doing it wrong, but I suspect it is PP2012.

Has anyone else experienced this issue? Does anyone have any ideas as to the cause, or cure?
