I'm wondering if you have an installation problem. I don't have SU/LO2015 on my Mac anymore so I can't compare behavior with LO2017. Still, as I wrote before, you really should be making style changes to your scenes in SketchUp, not in LayOut.

@unknownuser said: That would have taken us a long time to guess. Yeah, I think so too . However TIG put me on the right track somehow. Thank you all for your help and being such a fine community!
