Give the glass some thickness or set the refraction to 1.0. Best,

Thank you, Anton! I used an old plugin by Rick Wilson "fixAspectRatio.rb", but it does not seem to work in SketchUp 2017. The problem is, my original scene has no gray bars. After using your line there are dramatically changes in FOV and focal length. But there are no gray surfaces in the exported 2D-image - a first success! Edit: One possible solution is to restore the old FOV values in the menu Camera Advanced (plugin tt_camera) after entering your code line into the Ruby Console.

It's a completely rebuilt plugin. There are very few similarities from 2 to 3. I'm not sure if this is the best way to learn. Any reason for not just using 2 for now to learn and then upgrade to 3 when you are comfortable with the features.

TIG is right of course but With Dynamic Components you can do almost everything you want to do. Try opening the Dynamic Components toolbar, (view > toolbars > dynamic components) select the hand (interact tool) and click on the guy that shows up when you open Sketchup 2013 (Derrick). Then go activate view > hidden geometry and click with the interact tool again and see what happens. Insert some more Dynamic Components from the component browser. Insert some more DC's from the Google Warehouse. Search about DC's here or at Sketchup website. Try a lot, fail a lot and you'll succeed! Best regards, JQL
