You are awesome, thank you.
I'm just still unsure how those degenerate faces came to be. That's one of the things that I still find mystifying, both in MOI and a solid modeler like Alibre. For the Baton Rouge saucer, the big chunky part was made from a solid and then Booleaned down to shape. To make matters odder, MOI originally wanted to fillet the edges. But, I had to knock off work for the night so I undid the fillets and saved the file, wanting to do more work on the model the next day and reconsider the fillet radii. That next day is when, after opening the saved file, it wouldn't fillet. Again, odd as all I did was save the file with no other changes.
Oh well, no worries. You are the best and I thank you.
