I have arrived in Blender animation hell and I need help. I'm trying to make a car door open by hinging it upwards - the problem I have is that the edge where the car door and bodywork meet is not perpendicular to the global axis.

enter image description here

When I set the origin / 3d cursor to that edge and try to rotate the door upwards it clips with the bodywork on the right side and disconnects from the body on the left.

enter image description here

Any pointers you guys can give me an fixing the rotation and make the door open nicely? (e.g. is it possible to create a hinge of som sorts?)

Thanks

Update: @haaringertroll @Mdkai

Thanks for your comments - it works but I have a new problem with the bottom part of the door. (also folding) I parented a new second empty to the top door part and parented the bottom part of the door to the second empty. When animating it seems to disconnect and eventually end up in the correct location. Any way to fix that disconnecting part?

You can add an "Empty"-object to where your 3D-Cursor now is. This you can rotate so that one of its axes aligns with the desired axis of rotation. Then, select the door, select the Empty and press "Crtl - P" to parent the door to the empty. With the transform mode set to "Local", you can then rotate the empty and the door along with it around the desired axis

If you need to align the Empty with an edge you set the snapping to Edge, affect rotate and translate and also turn on Align rotation to target

This will snap the Empty on to any edge and also align the axis along that edge.
