Thanks so much for sharing, very generous of you! I'm relatively new to SketchUp/Layout, and am trying to produce a RCP. I need to dimension the exact positions of light fixtures, switches etc, generally to centre of fitting. My question is, how do I position them in Layout in exact locations on my plan, since there is no tape measure tool in Layout? And I would not be able to use the Layout symbols on the SketchUp side first, the way you've created them, am I correct? Hope you can help, thanks very much!
