I previously had a bad problem of seeing lines and curves through shapes and surfaces . Essentially I could see all linework through my 3D objects. I couldn’t figure out what it was so I unsinstalled and reinstalled rhino 5. This fixed the problem, but came with other a few bugs that required the update. I figured it would be fine so I updated Rhino again and of course I can now see line-work through 3D objects again. This is especially true when I have a lot of lines in my scene.
I have the latest update for my TitanX graphics card and have tried installing older and newer drivers as well. If I draw a few lines and then create a box the issue doesn’t happen, but none of my work is that simple.
If someone could help me figure this out it would help me out a ton. I have spent waaay too much time troubleshooting this in the dark.
