Certainly, its called DXF. Your CAD program needs to Export a DXF file in the format you need mm or inches, and in the version your software will Import. Since your using a K40 and LaserDRW I have no idea.
So it turns out your LaserDRW will not Import vectors, and that includes DXF files. There is a plug in for Inkscape thats allows it to work. Good Luck.
