Rotation axis in parametric models

This must be simple.  I have searched and can't find the answer.

 

I have a simple (parametric) cabinet design where the various elements are components.  If I rotate one of these components, everything is fine, until I change a design parameter that results in a change in position of the component being rotated.  The rotation axis remains fixed in the overall model space, so the rotated component ends up in completely the wrong location.

 

How do I ensure the rotation axis is relative to the component coordinate space, and not the overall model space?

With the component rotated along its lower edge

And then with the height parameter reduced, which results in the rotation moving the component away from the rest of the assembly.

Please attach your model so the Forum users can reference to it.  If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it. If needed, ZIP a F3Z file.

I think you need to add some Joints to this assembly to make it behave correctly with your parameters.  Model attached with a few required Joints.
