Poser axis get confused. Reset the prop back to zero and reattempt with as few dial turns as possible. Or use the tool icons not the dials.

heyas; my hypothesis is that it is 'gimbal lock.' if you rotated it 90 or 180 degrees on one axis to get it to point a particular way, then try to rotate it normally, this will sometimes happen. try rotating it a bit less than 90/180 degrees at first (ie: 89 degrees or 179). see if that helps.

Thank you for your help, but nothing will do. Finally i export it from Rhino and import it in Poser again and now it works. No idea what this was. No it works. Thanks

I had the same problem with a bracer prop I made in 3ds max and I managed to fix it by re-aligning the object's pivot point in Max (the pivot point becomes the object's 'origin' when imported into Poser) to Max's world space co-ordinates. I loaded up object into Poser again and got the Z-axis to work properly again. I'm new to modelling here so I'm not sure exactly what happened. I've read that Poser doesn't use the conventional 3d co-ordinate and axis system adopted by most other programs. I believe Poser's Y-axis is other programs' Z-axis. Nuke
