Is anyone having a screen glitch within the model ? I am having large planes of textures interfere with my modeling view, within my updated SU2017
Can’t easily see what the problem is in your still image, but it’s common to have glitches if you have two surfaces that are the same distance away, and have different textures.
To me this looks like distance artifacts - is your model very far from the SketchUp model origin? Did yo use an imported AutoCad map file as an aid to building your model?
