RHINO 6 BUG , deletes all geometry, can't control-z to get it back

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?

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 :slight_smile:
