I just tried out SketchUp 2018 and it renders edges in quite ugly way in viewport (and in PNG export too), as if they were doubled. Here’s a comparison how it looks in SU17 and SU 18 (see fullscreen):
It’s not just that I’m over-aesthetic. Neat rendering of edges has utilitary purpose - it shows whether there’s an unprecisely duplicated edge or not. Very useful when importing stuff from CAD. Now I couldn’t see that.
Can you tell me how it looks at your computers? Is it just my graphic drivers or Trimble spoiled that.
