Hello Steve,
Thanks for the kind words but the Vortex in the images above is not mine. Krille did an awesome job building it, mine is not finished yet and probably won't be this year considering the Corona situation.
I talked to the guy that did the laser cutting for me; the software he uses is RD Works which cannot read DWG files directly but can read DXF. There are many programs and even online converters that can convert the DWG files to DXF, you just need to google it and many options will show up.
I hope this helps.
