Rhino 6 crashes when copying elements between files

Rhino 6 crashes when copying elements between files.
It also crashes when you try to revert changes instead of saving the file.
The files are probably v5 files to begin with but have since been saved as 6.
Any clues? I have gone back to using Rhino 5 in the meantime, as I find 6 too unstable… despite the improved make 2d
best wishes


Hi Clem - does Rhino crash when you start two new documents from factory-default Rhino 6 templates and copy an object from one to the other?
Are you sending in crash reports?
Could you run the Rhino SystemInfo command and post the result here?

Dear Wim,
So i tried what you suggested and made two drawings with the default small metres template and copied objects between both with no problems…

Should I put my models into a new drawing made with a default template and see if it works?
The only setting I usually change in the default template is the precision…I draw in metres but like my precision a like a millimetres template.

I also posted the sys info details.

best wishes

Hi Clem - Since it seems that this is something file-specific, please post the files that you are normally working with so that we can try to reproduce the issue. Thanks,

Hi I narrowed down to the blocks with the long tables and the loungers…
I am building models of urban beaches if you a wondering what an earth I am doing…
The blocks originally come from sketchup warehouse, but I imported them as trimmed planes and then modified them a bit.

Best wishes
