Hi Altitude,
I use Inkscape and it seems that the svg it exports has problems with other apps as weel as with case builders (formulor).
I'm on vacation far from my main computer, i won' be able to give you files before next sunday.
But what you can try is to install inkscape, load the svg, then "save as" eps.
Uncheck "rasterize filter effect" then you should be able to load it in corel draw... I never tried Illustrator.
For the PCB measures in Kicad, i set a small scale, then i move the cursor on the first point of the measure, press "Space" (it sets the reference point).
Then move the cursor, the distance X,Y are shown from the reference point.
