This might help (I searched for illustrator settings in the forum search bar):
One of the replies in there included this:
Peter, I had my Illustrator Artboard set on Pixels as the unit of measurement. That was causing it to export the SVG incorrectly.
So if you can figure out how to find the Artboard and set it to “in” instead of “px” things may get better. There doesn’t seem to be any list of illustrator settings useful for fritzing around (and they would likely be old and perhaps now out of date anyway.)
