In a sense,

If you want technical data files with an ability for a machine to MAKE something accurately, you use Nerbs/Cad stuff.

If you want to make an "Image" of something, for some, poly modelling may be better/easier.
It's all in the mind set.
For me, coming from the likes of Hexagon poly modelling to MoI was like the world had become a modelling joy!
But I come (Very originally) from a background of engineering/ fitting and turning and mechanical drawing

Horses for courses.

PS I can/ have taken my MoI files into the likes of ViaCAD to produce viable dimensioned drawings "blueprints" which model makers could actually use.
