Any mesh repair likely for this?

I’m looking to salvage many hours of care for a project that’s gone buh-bye. Cannot believe the corner I’m painted into, so if the symptoms look like something you’ve faced, please advise how to fix. Can anyone tell me how to resolve the t-splines file gone to heck? Looked this way last night:

now smoothing is dysfunctional:

Hi Steve- TS has a smoothness setting in the heads-up display - I don’t have it loaded here, so no more details, but look for that.

You may have some issue with the polygons, try using _tsLayout to fix it.
