Sketchup 2020 is causing a bug splat when I multiple copy
Pretty much impossible to give you any help with so little information. Can you share the model file and tells us what you are copying and how many copies?
What is the graphics card? You entered “good enough” which unfortunately is good enough.
Have you been sending in the Bug Splats with your name an/or e-mail address attached so someone might be able to look them up?
I found ourt that this was a known fault and I have updated to latest version of sketchup and this cures it
