Hi,
I am having an issue where I have swept these surfaces around a curve and I’m seeing double of them in all the different display modes? In the image below I have backfaces set to red in the shaded view, but the double surfaces are there in ghosted, rendered, arctic, wireframe etc. Anyone got any ideas whats causing this? I’m using Rhino 8.
The developers will want to see your system info.
Type _SystemInfo and copy paste the result in a new post…
Is everything miles from the origin? Is your OpenGl support horribly out of date or just crap? It’s one of those.
Are you able to update to Rhino 8.8? Or is there a problem? That is in addition to checking distance from origin.
Also, I’d suggest updating your driver (but I don’t think this is the issue here).
I think I would paste text instead of a screenshot…

All the geometry is based around the origin, same thing happens if i paste into a new document as well. Additionally - same thing is happening if i open file on other computers as well.
Your NVIDIA driver is from last year. I’d try to update.
Have you got a small part of the file to share that exemplifies this?
Can’t share it unfortunately - will try to update driver as per martin’s suggestion - hopefully that fixes it!
If this happens in all files, you should be able to create a small example file with similar geometry which you can then share…
Or copy and modify some of your delicate geometry and share it.
According to your SystemInfo, you’re on V8 SR0…. Try updating to the current SR 8.8.
