I have a polysurface which came from a topography, when I look at it in Rhino, its all smooth. When I try and export it, the stl is jaggered and don’t resembled the object as displayed in Rhino. I’ve tried rebuilding the surface and modifying the export parameters for stl, I just can’t get it to be smooth.
This is what it looks like in Rhino
How do I improve the resolution of the export so that it resembles the polysurface?
