Hi Cuwaert,

I also use DraftSight. It's almost a direct clone of AutoCAD, so I fell into that easily for my 2D work.

I haven't been able to do anything with any free 3D CAD packages. If I could get over that issue with converting SW 2007 files to SketchUp I might have a chance with that. SO far, the closest is that KeyCreator software for $3500... too rich for my blood

Larry, Did you draw those wing sections in SketchUp or were they imported from some other software package? I'd like to find out more about that.

Thanks,

Bob
