I actually did search for Opensim(ulator).
Since I am using FreeCAD and OpenSimulator - and am preparing to utilize both in one project. Right now Blender is mostly used in the Opensimulator Ecosystem - but i believe there is huge potential for a FreeCAD dedicated 3D World/Project. I am looking for possible collaborators. Any opinion(s) about that?

Back in 2011 it was not necessary to create an account to be able to post. So he won't receive an email notification of this topic's activity. I would be very surprised if he still lurked on the forum after all these years.
No, i was not aware.

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 information (as parametric data.)

Examples of curved lines & surfaces in Wavefront OBJ: https://stackoverflow.com/questions/438 ... ile-format
Specification? of the format: https://www.loc.gov/preservation/digita ... 0507.shtml

I'll keep thinking about this/take a deeper look (in or around `Mod/Arch/importOBJ.py', then?
I saw your name plenty in the git history. Unless you guys are an army of Yorik :P)

Thank you
Kindest regards,

Post is 5 years old, @yorik is not gone, but some others could be not active anymore on the forum, so if you don't get answers, don't be upset.

this old post no longer has much value, the versions of Fc have evolved since then, if you have a real problem with a current version post a new one with all the information required

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.

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://forum.freecadweb.org/viewtopic. ... 79#p349379 but that's for Dxf that's a completely different codepath it looks. (I commented on the issue nonetheless.)

We can open a new thread or issue but I'm fine with this one. The title for one applies ;)
I'll keep looking/thinking about it. It might not be a lot of work for just what I want but yeah I share a similar worry as Yorik which is if I end up doing for each importer/exporter of .OBJ (the other ends would be Blender and the entry for our game) then I am afraid about doing it wrong on all.

That's why I had pointed to these two resources in my other message. These are more notes for self.

Thank you again!

Best,

I'm very happy to be wrong in this case.

But if the topic is old as said by @papyblaise it is better to open a new post maybe quoting the "very old post", even if some moderators do otherwise, but they are moderators, so they have a better knowledge of what is good and what is not good, and usually they "bump" old post if maybe there are some PR and similar things, to see if maybe someone has some "recent news".

But as there is no clear indication of what is a good practice, and recently many people came here as new users, it is better to be clear, and noting this sort of things. (as many new users are very susceptible :D).

Kind Regards.

(I know I started another topic, but the question got asked here)

I have found https://help.autodesk.com/view/ALIAS/20 ... AFE7E1A59D

I'll do more digging (and likely report on the new thread.)

So the other topic I had created: viewtopic.php?f=3&t=75373

And that is not all! From a similar [url=https://devtalk.blender.org/t/nurbs-imp ... _chapelain]thread[/url ]on Blender: https://ayam.sourceforge.net/

I've got so many questions! *Excited*
