Solution for closed polysurface

[minhha2001]

Hi all, are there any solutions to smooth the geometry of a curved polysurface? I use enscape for rendering and the result is really disturbing.

Thank you all

Rebuilding the perimeter before extruding would be one way to do this…

Hi Martin, you mean rebuild curve? I tried even but the result ruined my straight corner

I’m that case split at the corners first and rebuild the individual segments

Hi @minhha2001
I think it’s just your render mesh settings - see this for details: Rhino Mesh Settings - Detailed Info [McNeel Wiki]
