Hi!
I’m new to Rhino.
I created a surface with two-rail simple sweep tool. This surface is very strangely triangulated (1st screenshot) but it exports properly as quads to OBJ. The bigger problem (these two may have something in common) is shown in the second screenshot. I cannot smooth these surfaces. Tried to play with sweep settings and then ApplyEdgeSoftening, nothing. I’m not in FlatShade mode.

Created another topic. Ignore this one. Sorry, I don’t know if it’s possible to delete a post. May admin do this. I changed my question in the other post.
