DaveR, do you not read my posts? There is nothing wrong with the file itself. The problem is the way Sketchup looks. So any file on my pc with my graphics card looks like this, and it looked normal in older version.
I found a thread (SketchUp 2017 Resolution - #7 by pvkarch) that “explains” this problem but I can’t believe that there is nothing I can do. Sketchup was supposed to be a userfriendly program and should be able to run on “weaker” graphic cards as well as on the monster ones. I’m using Autocad 2017 and if Autocad’s AA can look ok, why cant SU’s!!! Dissappointment…
