Open Nurbs / IGES file formats

 From:  Schbeurd

Hi,

I'm not really familiar with file formats that support Nurbs geometry so I'm wondering what the differences are between 3DM and IGS (if any).

Is it just a matter of personal choice or are there reasons to prefer one rather than the other (provided that I use software that can import/export both formats of course).

Any information welcome.
Greetings
