Undo Toposolid geometry change hangs Revit 2025

[norman2KMXQ]

This has happened to me a couple times now when modifying a fairly complex Toposolid:

I deleted a Toposolid point that i decide I want to bring back so I hit "Undo" and this results in Revit 2025 hanging (no error message just "Not Responding").

The first time it happened I left Revit running over my lunch break thinking maybe it just needed extra time. When i came back it still was "Not responding" so I had to force quit and restart.

Anyway, just wondering if anyone else has had this problem.

Did you ever find a resoluton or workaround? Mines doing this and it extraordinarily unproductive.

No - i just muddled through, saved often and tried not to use Undo. I haven't had to do much toposolid editing recently so I was hoping maybe it was fixed in a recent update - also I'm using a new computer with upgraded specs as of yesterday so maybe that will make a difference (for me).

Also having this issue, haven't found a reasonable solution/workaround. Very frustrating, can't get any work done.

I've had this happen a few times now, while I was adjusting the elevations. Very frustrating to say the least. It just happened to me as I was cutting a section through the toposolid. I'm using 2024 at the moment.
