Marshmallow Crossbow

I was wondering if anyone could tell me help me or how to make a file to create a Marshmallow crossbow on the X-Carve, I tried to convert the plans that I found online but they did not turn out well at all.

These look like they should work. You might need a little post-carve tweaking (drilling holes and such).

Adobe illustrator CS3 can read PDF files then it can save as SVG

Inkscape can read PDF and save SVG

Thanks B.F, I need to get Adobe Illustrator.
