I use dxfout for cutting templates in a small CNC machine (simply 2D shapes with just the one cutting depth for the template thickness).

I can easily do this with Autocad using versionR12 dxf output and it works fine.

But when I dxfout from Intellicad 6.1 using either versionR12 or R13 (R13 is not an available export from Autocad 2004), Intellicad added two extra weird airfoil shaped entities.

Any help on this one? I am trying really hard to go with Intellicad exclusively but I keep running into roadblocks along the way.
