Thank you Michael for your previous response; spot-on as always.

This is a proposed enhancement for the Scale 2D command.
The situation was such that the target object set needed to be adjusted to match the size of a relative item, which was disposed at some vertical distance. I picked two points on the target set, but when I pick the second reference point from the relative item, the resulting scaling factor seemingly vectored the vertical distance, making it difficult to match the two sets with respect to the 2D (horizontal) plane.

Suggestions?
Should this command form offer an option to ignore non-coplanar coordinates?

Many thanks,
Mindset

PS … I realize now that the first reference point (on the target) was also not coplanar with the base point.
Perhaps all input points should be 2D for this command... ?
