patch boundary question

Any thoughts on why when I make a circle, use that to trim a hole in a
surface and then use that edge as a patch boundary the function works,
but if I go back and change the circle to another shape, say by using
lines and arcs, the patch function fails? The error reads patch has
open boundary and the hole as well as the outer edges of the surface
highlight.

I want better control of the shape I use for creating the patch
boundary and this seems to be a bug, any thoughts?

Cheers,
Brad

 

You could try using right-click>'select loop' to select the edges, sometimes
there are little bits that you miss when selecting the edges by hand.
