Updating Worksession disables undo!

Rhino Rhino for Windows
1

Every time I update an attached file in a Worksession (and possibly with other worksession related commands), it removes the ability to undo, saying ‘Nothing to undo’ and I cannot then use undo until Rhino is restarted. Quite annoying!

I have VisualArq and Vray installed. Any potential fixes possible?

What do you mean by “update an attached file”?

If I Attach an additional file to an open Worksession then update continues to work.

If I change the active file Workession then update history is lost. This is the same as when I close a file.

I am working in File A which is the active model in a Worksession I have opened.

I update File B in a separate window and save it.

Then when I update the File B worksession reference in File A (see image below) all of my undos are lost and the ability to undo going forward is also lost. The active file never changes and so I expect my undos not to be affected.

When I say undo, I am referring to ALL Ctrl + Z undo commands.

Hope this clarifies things.

I see the same behavior. Worksession appears to flush the undo history whenever a file is dettached. Update is equivalent to detaching a file and then attaching the updated version.

Thanks for confirming - do you then also experience not being able to undo anything after this?

Its one thing losing undo history before the reference update (which I could probably live with), but not being able to undo afterwards makes this feature essentially unusable. Restarting Rhino with every update makes this bit pointless.

Hi Ben, thanks, I’ll check this.
@Ben_B - so far, at least with small models in a simple test, I see what David sees - Undo os cleared but subsequent operations can be undone.

Hi,
Has there been any progress on this issue ?

Still seeing the same behaviour. Also using VisualARQ.

This issue maybe caused by VisualARQ,

Thank you - yes that makes sense.

Hopefully this will be fixed with the next VisualArq update as they suggest.
