> Internally MI is working on spherical coordinates. I really hope this is not the case. I hope that MI is at least using the "current coordinate system" from the MapBasic window. Not having a version of MI past 6.5 available, I can't test this with the Rotate tool, but try the following:
1. Make sure your map is using a projected coordinate system, rather than lat/lon. A conformal projection is ideal. 2. Open the MapBasic window (Options->Show MapBasic Window) 3. Click on the title bar of your map window to make sure it is the front one. 4. click in the MapBasic window and type "Set Coordsys Window FrontWindow()", then hit ENTER. 5. Now try drawing rectangles, converting them to regions, and rotating them.

Actually it might. Internally MI is working on spherical coordinates. I have noticed that if I move a polygon any significant distance north/south it becomes distorted apparently due to convergence of longitude.
