Excellent idea, and congrats to RM Mottola for coming up with the concept. The program seems to work well, however, when I tried exporting a dred outline (.dxf file) and importing it into CorelDraw X4, all I get is a bunch of objects that are 0" x 0". This could be a CorelDraw X4 issue, of course, but I have imported .dxf files into it with success before. Anyone had more luck than me using a .dxf file export from the program?

Cheers,
Dave F.

Very cool, does anyone know what numbers to punch in for an OM?
Could you possibly take the file somewhere to get printed out full size?

Thanks for bringing it to our attention. I haven't visited that site for awhile except for the saggita table and didn't know it was there. I 'll have to read the artical in AL#97 too. I guess I should go over the site and see if there is anything else new there. :P

I was able to export a .DXF file from G-Thang and then import it into Sketchup (free download from google). I used it to design a Baby Drednaught while playing around (shaped like a drednaught but sized like an OM). This is the result:

Here is what I came up with, roughly the same size as an OM. In regards to soundhole placement isnt it rather important? I have mine about 4 inches back from the top, sound right?
