Hi Michael,

I was playing around with Nsided and modelled a test surface with a 5 sided hole (see attached) applied Nsided patch and it didn't come out to crash hot so I thought I'd uploaded it for you to test other solutions maybe.

Anyone else can have a go and see if you can get a nice tangent continuous surface from all 5 surface edges :)

BTW I have one solution however it's still not perfect.

Cheers
