OK, so you've downloaded the instructions and CAD files from the downloads page, but where are the CAD files??
We decided to export our cut paths as PDF's so as to be accessible to as many folks using as many software setups as possible.
The PDF's are in vector format already, so you should theoretically be able to import them into your favorite CAD program.
If you're having trouble, let us know. We may be able to export in a specific format, or to find one that's more universal than PDF.
