Lines/facets on the model?

Hello,

 

When I import my .obj model from Rhino to 3d coat for Voxelation (for edge smoothing), I get some lines/facets on the ring model.

If I try to subdivide, the model cracks at the seams.

 

What am I doing wrong?

I checked my Rhino obj export settings and I don't see anything wrong.

 

Thanks for your help

A picture would be very helpful here.sounds to me like you are bringing it into surface mode and coming from rhino your model is probably not water tight and its splitting open when you try and smooth.

I'm going to suggest the opposite from Carlos an and make sure you import directly into the voxel room with a poly count at a million. Smooth should work just fine now.

Hi and thanks for the replies,

 

I tried to post an image but I'm apparently restricted ("You are not allowed to use that image extension on this community.")

 

I've tweaked the .obj export settings in Rhino and it looks like I have less of that faceting.

I still get some weird holes and dings, but I can use fill or smooth for those.

I scale my model times 3000 on import, and the poly count is about 3 million .

 

If I apply "smooth all" I can get some lines/facets on previously smooth surfaces, so I have to use the smooth tool even though I'd rather use the smooth all to have a more even smoothing.

Maybe my geometry isn't watertight out of Rhino, I'll have to check.

 

Is there a way to create an "area" to isolate when an effect like "smooth all" is applied?

 

Thanks
