Transform Rotation into location problem I have a gear and it needs to rotate two full turns (720 degrees) to open a door which should move up for a length of three blender units. The transform works for about 180 degrees then the door falls back to the start point.
There is no difference if I'm addressing the transform Rotation Constraint to the gear or if I'm using 'the door Open Empty' and rotating that object.

Anyone know a solution?
Add driver to the location property with right-clicking:



Setup the driver like this:



Now the Empty's Z rotation controls the object location.
