# 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?

• @JonnyPoet You can find drivers in Graph Editor > Mode: Drivers (its F-Curve normally) > open properties panel (N) > select driven channel on left, edit on right. If you want the Y axis then edit the Path for property to :rotation_euler.y – Jaroslav Jerryno Novotny May 15 '15 at 9:38
