I think that i can help you about design and workshop drawings of frames for bicycle, but I don't understend what you mean when you sead R2V?
I design in Autodesk Inventor, but I can output workshop drawings in dwg or dxf, or...
If you are interested, I can send you some of my works, and you can see my CAD quality...
If you can send me some dimensions, and more pictures i am sure it will be done very quickly!!!
