Does CorelDraw import or read SVG vector files yet?
And in other news, I'll be looking to get replacements for some broken 1970's era O scale AHM boxcar ladders (I acquired a small quantity of these cars and upon finding out how few different ones were made -- 3 or 4 each of boxcar, reefer, flatcar and gondola-- built a collection representing their entire lineup).
Should be simple to design...as soon as I get one off my small collection and put the calipers to them. I could draw 2d diagrams in Inkscape (.svg) or 3D ones using SketchUp Make (.skp)
