If i remember correctly there was some disscuccsion using FreeCad to do so… you … no wait… long ongoing and actual thread:

From Blender Subdivision To N.U.R.B.S. (IGES) for free

I used MoI 3D for a number of years because I needed an accessible NURBS editor for product models. Solidworks is super-expensive compared to MoI, and MoI’s UI / UX is much more lightweight. Nowadays I’m only using Blender and ZBrush for modeling, but I’ve still got a MoI license for when a client needs NURBS to poly conversion or vice versa.
