EDIT:  Thankyou for everyones contributions.  I do not currently have the time to assess all the solutions offered, and mark one correct as I have to focus on other work now.  But I will return to this later.  Thanks again.

Hey Up!

I'm trying to produce an animation of this door opening from 0 to 95 degrees.  I'm not very experienced with motion studies but I can normally get them to work eventually.

This model I can't get close.  Even limit mates are proving a problem.

I think it's because the geometry is a bit odd with a skewed axis.

I've exhausted all my ideas!

Thanks for looking.
