Any way to fill irregular holes?

I don’t really care about surface quality here, I just want to hit g0 within joining tolerance, and g1 would be preferrable, but not necessary:

Note, the result cannot be a mesh! It needs to be a polysurface.

Is the result of the Patch command what you need?


otherwise perhaps BlendSrf using ChainEdges to join the segments for the top and bottom edges:

Awesome, thank you very much for both solutions!

use patch
lol too late

Have you tried using the Patch command? Seems to work. There is a problem joining the existing surfaces though, see image. You can fix it with JoinEdge if you don’t care to much about precision.

haha wow everyone is so quick on this forum

you can get that to join, play with lower stiffness 0.5 for instances and use 15 spans in each direction.
edit: ok you need something like 20 spans-
