[Solved] Why do I get lines on my model when importing in sculpt ?

[3dn00b]

Hi all,

When I import an stl mesh for voxelization into sculpt mode, I get lines on all the curved surfaces. 
The only way to reduce them is to subdivide before applying, but it's not perfect and I still have to pass a smooth brush everywhere to try and get rid of those.
How can I avoid those lines? 
Could it be because of the stl export settings in Rhino3d? 
I attach an image to illustrate. 
Thanks in advance for your help.

Could you share the model to take a look ?

Yes please.
Thanks

 This topology makes it difficult to achieve a perfect smooth surface.

I imported it in surface mode, subdivided it 3 times before hitting apply, and then converted it to voxel mode. After which use the command smooth all once.

Hope this can help you

Thanks for trying. Question: how do you convert to voxel mode?
Without a shader it's hard to see the smoothness of the surface on your screenshot. 
When I follow your steps, it seems that in sculpt mode, the smooth brush doesn't smooth the sharp angle where the bezel connects to the shank, which is why I'm using 3dCoat in the first place. To smooth sharp angles. 
So there is no alternative to bringing it straight into sculpt mode and using the smooth brush everywhere.

when use any sculpting tool, pressing shift switch that tool to smooth mode.

Look this video about surface vs voxel

Hope it help

Thanks but earlier you said "and then converted it to voxel mode". How do you do that? 

[Carlosan]

To switch to surface mode press over letter V (voxel mode). The layer prefix change to S (surface mode)

To switch back press S again, layer becomes V.

-when switch back to V, you loose definition, be careful-

Problem solved. I needed to change a value in Rhino's stl export settings. ( Maximum distance, edge to surface)

Thanks to all
