I just upgraded to 7 from 5 a few days ago so I’m not sure if this is a bug but feels like it is-
the “what” command as well as “seltrimmedsrf” commands have always pointed out to me what was a untrimmed surface and what is not, however, I was using edge srf as usual which should have predictably gave me matching cvs along natural edges but it gave me a bunch of spans which I thought was very odd as I’ve never had this happen before unless it was a trimmed srf. Anyways, I checked my usual tools and it didn’t show any trimmed surfaces but I decided to hit “untrimall” anyways to see if anything would change and sure enough it “untrimmed 1 loops” and worked fine after that.
So my question is this a bug or are there situations where rhino won’t indicate a trimmed surface correctly? Only new command I’ve used (not sure if it was on this surface) was the “refit trim” command.
