The answer is yes for both of your questions.
I can not tell you exactly how to create your own interface box, but I can tell you about the CAD software. The Torchmate drivers software will accept DXF files from any CAD system, the cuts may not be ordered, offset, or have lead-ins, but the drivers software does not care.
