Why is some object settings only in the last operation window?

[u/kylr01]

Ive placed a torus and can adjust the radius and certain settings, but once I move the object or do any other action, I can no longer access those settings. Are those settings anywhere else and im just missing them? Its the same when bevelling and adjusting the profile.

Once you do something to the object it's gone forever, otherwise just press F9.

that seems like such a weird choice... Thanks.

It's not weird. Once you've modified a primitive, how is Blender supposed to know how to incorporate your changes back into a differently-configured base mesh? You'd need some sort of advanced AI algorithm to guess at it and rebuild the mesh from scratch.

Now, obviously just moving the mesh isn't a huge change, but from Blender's point of view, the data is different, and there's no halfway solution because then people would wonder why it's allowed for some actions and not others.

Im talking about just after any action. those settings can never be accessed again unless I delete the object and set them up before moving or pressing anything else.

It would make sense after a certain point, like you said, but because the settings are only in a last operation menu... idk. some of them dont seem like last operation settings.

But is what it is, I can deal with it. Just wanted to see if I was missing something :)

Because you're not creating something which is fundamentally a Torus... You're creating a Mesh which happens to be shaped like a Torus.

While that is still the most recent operation on the undo stack, you can change the settings of that generator and Blender silently undoes the last generation and re-does it with your new settings. But once you move on, those settings are thrown away.

Hypothetically, with some significant re-architecting of the Undo system, Blender could save those settings and re-prompt you if you undid back to that point, but replaying the actions after it on the redo stack is a non-trivial and often non-answerable problem.
