Undo undo - Preserve selected geometry from Undo

Rhino Rhino for Windows

Is there a way to preserve some objects from being undone on Undo?

It’s very typical - you try an approach, which turns out to be a false lead but, you realize that some objects on the false lead would actually be useful for another better approach if you back a few stepos and try the new approach. But Undo will do away with those useful objects (usually some marker or helper lines etc which would be useful in next attampt).

So, is there any command that can preserve some (selected) objects from being affected by Undo - or is there any workaround that has proven to be useful (quick and dirty would be good enough).

If no such command exist, then I suggest adding it to R6, because it’s a “ten times a day” thing. Really.

Hi Rolf - Copy > Undo > Paste… does that do what you need?

Ah, I always tend to think that I must persist geometry for reuse since I do not trust my memory if I get interrupted… :slight_smile:

Hi Rolf - I suppose you could make a dummy file someplace called temp.3dm or something, and make macros to export to & import this specific file.

! _-Export _Pause "C:\Users\pascal\Desktop\temp.3dm"

! _-Import "C:\Users\pascal\Desktop\temp.3dm" _Enter

Will that export only selected geometry?
