By default, of course, the "rotation center" crosshairs is in the center of the rectangle. Let's say I'd like to program it to be at the lower-left corner - how could I do that?

Just to clarify, my reply was that it (i.e. programmatically setting an object's rotation center) could not done with tiles alone, but that it was "easily accomplished" if the user were willing to resort to using a single line of *textual* script...

Thanks Scott. Is it the case that this only works when Sketch's heading=0 ? I figured out how the 2 arguments affected placement of the rotationCenter (rC) and created 4 scripts - each one placing it in a different corner. However, when I did a 'turn by' (or simply changed the value of its heading) on the sketch, the rC scripts then had no effect.

Hi, Randy,
For it to work correctly on a sketch that has been *rotated*, you need one ugly little refinement, which is required because of the (unfortunate) way that morphic handles rotations. Try this instead:
