Rhino surface object is not valid

Does anyone know what this specific error denotes? It happened when I joined surfaces into polysurface. Looking at the naked edges, there were no actual edges, just a point at a joint. Typically this point was at a tiny edge (usually a tiny surface created by FilletEdge) but not always.

rhino check error

It’s not quite the same error message as this one: Rhino surface object is not valid

Thanks,

Any luck?

Thanks @John_Brock for the McNeel Wiki reference page. It had some commands I did not know exist which will help in the future to find bad objects.

Before I posted this check error message, I had already gone back in my file, exploded the polysurfaces, found which ones were bad, and through various means, usually with un-trimming, fixed everything. The post here was an “after the fix” question to try to learn how to prevent those same issues in the future.

Thanks!
