Bad OBJs in Cinema 4D

[Jeff Klein]

Great, thanks again.

Ah crap, that’s a Rhino 5 file and I have Rhino 4. It won’t open.

[Jeff Klein]

Damn it. Thanks for trying and let me know if you have any other ideas.

I dl’d the currently free (because it’s a WIP missing features) Rhino for OSX and it says “Many bad objects were created while reading “Speedflex_Assembly/SPDFLX.3dm”” – I tried exporting as a Rhino 4 and it said some of it is Rhino 5 only — I can’t see any visual differences so here it is Just in case https://app.box.com/s/c3sgoxqzwqm1bkjm7y4u

So it looked just as messed up as in the screenshots I posted? Thanks again for trying.

I opened the file that Brian saved in Rhino 4 format and it is indeed supremely screwed up. I don’t know that’s how it is in Rhino 5 or if that’s an artifact of the conversion. In R4 none of the surfaces are welded, and they all seem to be doubled. Even if the surfaces weren’t doubled up I think it would be hard to join them together.

If you’re not careful in Rhino it’s very easy to create reasonable-looking objects that are technically unsound and in those cases it’s usually impossible to join the surfaces into water-tight objects. When that happens it can be a challenge converting the NURBS to polygons. I think that’s what happened here.

Very odd if they were using these models to create prototypes. I don’t know how they were able to do it.

Sorry for the non help.

Thanks for the response. I found someone with Rhino 5 and the model looked exactly the same as it did in Cinema 4D. They also mentioned it might be a nurb/poly thing. Anyway, thanks for everyone’s help!
