Surface morph problem

Hi, I’m new to grasshopper and rhino. I am just wondering if it any possible to use surface morph to trimmed surface? I used surface morph and it did not work at all. Can anyone give some advice on how do I do it? Thanks.

It looks to me like it’s working perfectly in R6, which is a pretty far cry from “did not work at all”.

Do you understand why? When you figure that out, you’ll answer your own questions. I lose interest when the goal posts are moved.
