Hello Erik,

I believe the trim worked for me in Rhino 7.

Thank you,

Yes, no real crash , but Rhino is not responding for longer than i want to wait…

Thanks for looking at it. Are you using the latest service release?

Hello Erik,

You are welcome. I believe that I am : 7.5.21100.3001, 2021-04-10
The Trim occurred instantaneously as usual.

Thank you,


RH-63887 is fixed in the latest Rhino 7 Service Release Candidate
