OK we are not yet one year in :

From bugging Blender about the same [1] I have been made aware of Ayam, which seems to support those features (NURBS in Wavefront .OBJ files.)

I am (gettit ? ) trying to compile it on my NetBSD.

So the other topic I had created: https://forum.freecad.org/viewtopic.php?f=3&t=75373 And that is not all! From a similar [url=https://devtalk.blender.org/t/nurbs-import-export/17581/14?u=germain_le_chapelain]thread[/url ]on Blender: https://ayam.sourceforge.net/ I've got so many questions! *Exc...

This is interesting anyway. I had no idea OBJ supported nurbs surfaces... An interesting question, however, would be: Are there other apps out there that support it? Otherwise, it would have not much use. (I know I started another topic, but the question got asked here) I have found https://help.au...

Thank you! I will create an issue and report

FWIW, http://www.uhu.es/francisco.moreno/gii_ ... J_SPEC.PDF has the "Free-form curve/surface section.
But again Idk anymore I feel pretty alone on this

So I see what you mean with the section not specified vm4dim I keep running into references of it being supported though, i.e. https://docs.fileformat.com/3d/obj/#free-form-surfaces Initially I was going to create a git issue over this but now I am not too sure FWIW there is a similar thread on the ...

Hi! As per the trailing discussion in https://forum.freecadweb.org/viewtopic.php?p=652924 ,I was hoping for the curved surfaces on my model to be exported as such in Wavefront .OBJ or using the Collada exporter There is one to represent curved surfaces in both formats: For .OBJ: https://stackoverflo...

Hi thanks fellows ! I was just going to reply @onekk not upset the least. I'm not expecting another reply for another 5 years :P Yeah the thread isn't the best: it doesn't relates in terms of goal but rather in the change to get there. (At least so it felt at the reading.) Another one is https://for...

The only real problem will be when exporting faces that contains curved border or even curved surfaces, since they will need to be tesselated. Hi Yorik! It's interesting you say this because the opposite led me to this thread: I am interested in exporting in OBJ (or Collada) with the curve informat...
