Aha. Didn't know about the boundary thing either. I typicall re-add a boundary at least a dozen times before I can finish a surface. Good to know...
I'm so glad that the OOPS command is still active and someone actually uses it!! Let's hope it never get retired.
Yes, it would be nice if there were a way to force boundaries to always be at the bottom of the list. This is a suggestion I've made to Autodesk, but it hasn't happened yet (I keep hoping). Adding breaklines after adding a boundary can lead to some very bizarre behavior in your Surface, until you sort out the order of operations.
My breakline operation was at the bottom of the list. Moving it to the top solved my problem. This is one good piece of info I was not aware of and may solve many of the problems I've had with surfaces.
