Shell / history not working

in the Rhino 6 for Mac WIP, I wanted to try using the History feature on an object after using the Shell command, but it’s not working and the “Broke History” dialogue does not appear.

Move one of the points of the polyline (History works)
Then Shell (I remove the top surface)
Try moving another point of the Polyline (History does not work, no error)

shell history.3dm (3.1 MB)

I may be wrong, but I don’t think the _Shell command supports the history.

Ah, thanks for the list! I’m trying to get back into using Rhino more frequently and I’m exploring some of these newer features that I haven’t used before. Thanks again!

Hello - History does not support editing of the child object - the bug I see is that Shell does not give a ‘History broken’ warning - it should.
