Jerry - Thanks for this review. Do you mind if we use parts of it
for advertising? ;-)

I did have a couple of comments about the scaling in Vector. See
comments after your quoted paragraph:

The Change-Scale function in Vector is an afterward/afterthought. It
is placed there only to allow independent scaling of lines in a
drawing. If you want to for instance make a drawing twice as wide
but the same height, the scaling function does this. This does not
work with arcs, so they have to be interpolated into lines before
scaling, then they too can be scaled(Change-Break-Interpolate).

If you want to scale everything in all three axes simultaneously, you
use the Cut-Paste functions, and set the scale to the desired
factor. That way all dimensional relationships within the geometry
will be maintained, but at the different scale. This works for arcs,
vector objects(groups), text, bit mapped images, etc.

Hope that is a little clearer now.
