Problems with Undo

Serengeti (Rhino WIP)
1

In couple of recent WIP versions, I am encountering Undo problems which I have never seen before.
File seen in the video is completely new and purged, so it’s super small. My Undo memory is set to 16 GB. As you can see I can Undo only once.

Dear @John_Brock,

This somewhat refers to another topic where you described the problem with long undo times.

There is something really confusing in the Properties.

In this tiny 20KB file, when I had Max memory used set to 4096 MB I had only 1 Undo.
When I lowered it to 256 MB I can Undo multiple times.

It depends on what the operation did.
Dragging a curve from one location to another requires a tiny bit of memory to record the step for Undo.
Attempting a MeshBoolean between two complicated meshes can use a huge amount of memory to record for Undo, and will likely push everything else off the Undo stack in the process.

All of what you wrote makes sense, of course.

Maybe I didn’t present the main issue clearly.

I did nothing in the file between two tests that I am showing in the videos, a file itself is new and almost empty.

If you can, please take a look one more time.

Action to perform: Multiple Undo of move Curve

Max memory used set to 4096 MB

  • I can Undo only 1 time

Max memory used set to 256 MB

  • I can Undo many times

With my Undo memory set to 256, I’m getting multiple undos in the list:

At 4096 set for Undo, I can repeat the problem you’re describing.
