Hi guys, I found a bug today.
Steps to reproduce:
add blockedit to the Options-general-“never repeat these commands” list
make a change to a block.
enter another block
run last command, which will be BlockEditApplyInPlaceEditItemChanges
exit block.
When you exit the block all geometry in the file will be deleted. Control-z will not bring it back.
Workaround: Add BlockEditApplyInPlaceEditItemChanges to the “never repeat these commands” list
Hello - yep, I see this here in the latest - thanks for the report.

This just happened to me in Rhino 7. Is this still not fixed in R7? I will try the workaround. I am still in shock.
Hello - as far as I can see this is fixed - can you please run the SystemInfo command in Rhino and copy/paste the results here?

Hello - That should certainly be fixed in that build - I cannot repeat the problem in 7.3, at least so far.
Are you doing exactly this?
add blockedit to the Options-general-“never repeat these commands” list
make a change to a block.
enter another block
run last command, which will be BlockEditApplyInPlaceEditItemChanges
exit block.
Just to make sure, can you repeat the problem if Rhino is started in Safe Mode?
Start Rhino in Safe Mode: Windows start menu, type in ‘Rhinoceros’ and look for the ‘Rhinoceros in Safe Mode’ entry.

Unfortunately, the problem still hasn’t been resolved in 7.5… Is there any way we could ask someone to look into that issue?
Hi -
Can you provide the exact steps that are need to reproduce this issue?
-wim
Hi Wim!
Thank you for your reply! Unfortunately I don’t think I can reproduce the issue right now but I remember the last command that ran before everything dissapeared was “BlockEditApplyInPlaceEditItemChanges” (that’s how I found the thread). Just like the author of the thread I was working within block inside a block and once I pressed “Exit” everything disappeared and I could not get the “Ctrl + Z” to bring back any of the geometry that I lost.
For now I added the "BlockEditApplyInPlaceEditItemChanges to “never repeat these command list” as Topsoil suggested 
Hi, the same happened to me twice this week. When I was finishing editing a block, closing the editor cause everything to disappear…

Hi this is still an issue in rhino 8 SR21. Happened to me twice and I can’t find a way to get geometry back 
Hi @Neva_Kocic1,
Can you help us by providing the steps need for us to repeat the issue here?
Thanks,
– Dale
Hi Dale,
I’m actually not sure how it disappeared.
I just noticed that undo didn’t work and I couldn’t get geometry back.
Next time it happens, I will look into command line and let you know.
Thank you for your attention and time.
Best,
Neva
I’ve had 2 users come across the same problem in the last month. It tends to happen when they are rapidly clicking inside of the block editor. Thankfully I was on a virtual call and could observe it first hand. I managed to capture this screenshot of the command history. After the highlighted command everything was gone.
I’ve come up with a way to replicate the event partially.
In repeating these steps a few different times I’ve noticed that if there is only a instance reference object in the world a popup comes up The block was not modified, it must contain at least one object but if there is other geometry in the world the popup does not appear. Curiously, the block definition that was originally open has been changed to include all geometry that was not inside of the block initially. It seems as though my users are experiencing this second option and upon seeing the model completely disappear their first instinct is to ctrl+z as quickly as possible. Reverting the instance definition back to its state prior to making any edits.
@Wade_Vollink if we had a customer of the month award I would nominate you right now, this is brilliant. I could easily reproduce
I also just experienced this bug today with the steps you described where I accidentally ran the command BlockEditApplyInPlaceEditItemChanges and was unable to restore all the geometry outside of the block definition
Michael I’ve found that adding _BlockEditApplyInPlaceEditItemChanges to the do not repeat list, as described above, mitigates this error. I’ve created a powershell script to set this in the settings xml on install and update for my users, but setting it for yourself is as simple as adding the command to the do not repeat list in Options > General.
RH-89760 is fixed in Rhino 8 Service Release 25
