I have often come up against a situation where ctrl+z stops working. I have both Ctrl+z and Alt+Backspace shortcuts attributed to undo, but sometimes they both stop working and not even going into the drop down menu works either. It appears to be very random when it stops.
Yup, me too, I’m not sure why but have given up trying to find the reason. I just save a whole lot now, often making a copy of certain portions and moving it to another location within the model (as a back-up / fail-safe) before doing complex changes (like with extensions).
This seems to be the biggest issue. Extensions allow you to push a button to do what appears to be one thing. However, behind the scenes, 30 steps are actually happening.
thanks @john_drivenupthewall … The last time it happened I wanted to undo the very last operation I had done, which was using the move tool to move a pretty simple face which had some auto folding related to it… Does that still come under what you mentioned above?
Understood and fair enough, however I’ve had times where a simple eraser delete of but a few faces / lines (seriously little) would undo only into random selection of what was erased or not at all. It isn’t limited to that function either though…
In SketchUp 2018 on Mac the setting migrated to the SharedPreferences.json file. This might also be true on Windows? @IanR your profile doesn’t say what version of SketchUp you are using.
