I'm tired, so this could be operator error. I placed a cabinet box in the LDE from the Cabinet Editor. I then copied it twice so that I could get a Plan, Front Elevation and a Side Elevation. I rotated the first cabinet with the Rotate dialog. I then deselected that cabinet. I then selected another copy of the cabinet to rotate, but this time the Rotate Dialog would not work. I then saved the project, and I was able to select the cabinet and use the Rotate Dialog. If I open the Rotate Dialog, close it, then open it again it does not work until I again save the project.
