Very simple and effective! Nice contribution.

The best script I have aver seen. This script totally rules.

Worked perfectly, saved a lot of time.

Thanks for the script, very useful. however I tried to use the function but when opening in AutoCad 2011 it says
Invalid or incomplete DXF input -- drawing discarded.

even though t picks the coordinates (I can see them in the dxf file opened with notepad). Do you know wht's wrong?

[Tom Etzer]

I had the same problem as dario.
The Name of the Layer was "0 " instead of "0". Therefore, i changed line 12 to:
"fprintf(fid,'LINE\n8\n0\n');"
Now it works perfect for me.
(Maybe a little late...)

Excellent contribution. I slightly modified the script to read airfoil data and generate the dxf to import with Hypermesh and works perfectly.
