Rhino polysurface object is valid.
Saw that no idea what it means And if its bad or good. Or how too make it go away,

Hello - use ExtractBadSrf to find the problem surface and then I would Untrim it, and re-trim with the surrounding surface edges. Feel free to export the bad object to a new file and post it here or send to tech@mcneel.com with a link back to this topic in your comments.
