Create a rounded cap following this blended curve

Hi, I would like to “cap” this organic tube/surface following this blended curve, more or less. When I do the “patch” command with surface tangency, it pancakes down too much/looks too flat. Any recommendations?

Rhino WIP V9 has a new command called _fillSrf
(WIP - Work in Progress)
test it.

you might split the *blended curve" and use _railrevolve or _networksrf

… or build the “cap” with more advanced techniques - combining 3 or more surfaces…

post you file to get more help !

and also give some background - what are you using the data for.

cheers - tom
