Hi terryc,

I didn't understand everything you said above, especially what an
"element" is.

I use Inkscape every day to create SVG images. If you're really doing 2
dimensions and not a 2 dimensional portrayal of 3 dimensions (with
vanishing point, etc), SVG images are excellent.

If, by "setting the scale", you mean being able to redefine the grid,
then you're right, Inkscape can't do that. But what you *can* do is
scale the group your rectangles are inside of.

View the attached SVG file within your favorite text editor, and note
the line saying:

transform="scale(2)"

I put that line in with a text editor. The rest I created with
Inkscape. So I can grow or shrink the whole drawing to conform with
whatever scale I want.

As you can see from viewing this file in Inkscape, more work has to be
done because the newly scaled group has to be moved to once again fit
inside the A4 drawing. For a simple drawing like this, that's also
easy. See this web page:

https://developer.mozilla.org/en-US/docs/Web/SVG/Tutorial/Basic_Transformations

Like I say, I didn't exactly understand what you need, but just in case
this is it, I can tell you I've had a good time with Inkscape the last
10 years.

HTH,
