Scales a selection set of objects with independent X/Y/Z scale factors. Very useful for contour mapping that was digitize/vectorized at the wrong scale. You could make a block of the objects, insert it with irregular scaling, then explode it. However this has negative side effects on the geometry, most importantly polylines are exploded all the way back to line segments that must be rejoined.

It is important to note that this routine only scales point coordinates, it does not scale nodal objects. For instance if text and block inserts are included in the selection set, they are moved to their new position relative to the coordinate scaling, but the height does not change. The only object type that takes on any significant transformation is an arc. An arc must become an ellipse fragment when scaled with different x,y values.
