I guess you are using Solidworks to engineer the Vortex.
Isn't there a possibility to save drawings in dxf form as well as dwg?
The basic drawings were generated by Solidworks, but the parts nesting on the balsa sheets was done in Audocad. Of course Autocad can save DXF files, but after recently reinstalling my system i don't have it installed at the moment.
It takes a while to convert so many files though, but if you can't find a way to convert the DWGs to DXF i can do it for you later this week. Just let me know if you need it or found a way in the meantime.
