Rhino 7 switching to Layout is extremely slow

Hi is anyone having the issue that when they switch to layout it really drags- I havent actually ever waited for it to be done switching because I’ve waited over 20 minutes before. I end up force quitting Rhino then I try and open it again and it won’t open- waiting again for another 20 minutes- then I have to hard reboot my computer. It’s really making work extremely difficult. Also if I try and open a new file it does the same thing. I just upgraded to Big Sur. Also upgraded my 2019 iMac Retina 5k 27inch to 40GB of data.

Hello - I have not heard of this before I don’t think - you open Rhino and click on ‘Layouts…’ and Rhino freezes for 20 minutes? Are you opening existing files or starting from an empty Rhino with a clean new file?


Pascal, I’m having that same issue now. I was detailing in a layout and noted Rhino was slowing. I saved and quit. Reopening the same file in model view was fine until I tried clicking on a Layout which freezes the app. I’ve had the same issue in other files. Could it be an annotation or display issue?
-To update, the freeze is for about 15-20 min in either Technical or Pen Display.

Please enter SystemInfo into the command line and post the results here.

ah Mojave, please send us a file so we can try and reproduce?

upload to McNeel


Also please try changing this setting in Preferences>OpenGL

That is the current setting. Changing it to…?

Hello - try 2x or even None, to see if that makes any difference.


The redraw between layouts is faster, but the zoom and scroll are still jumpy.
Sending the file now…

Bad object in the file buggering the render mesh creation.
