Does the style used for the viewport have Dashes enabled? Does the component containing the geometry actually have the "Snuggler" tag? Is the geometry tagged (it should not be). If you share the LayOut file so we can see exactly how you've set it up, we can certainly identify what's going on. If you don't want to make it public, snd it to me via a PM and I will help without sharing the file with the world.

Are you running LayOut from the .dmg file or did you actually install it in Applications? The second option I gave you should force LayOut to rewrite the location of the SketchUp Model panel next time you open LayOut and save a project. If LayOut was properly installed, that is.

Text created in SketchUp won't scale with the geometry. You could create the symbols in SketchUp using 3D Text (it can be created without extrusion) so the text is geometry as is the circle or other shape. Then you can set the scale for the resulting viewports in LayOut when you create the scrapbook page. Either leave them as viewports linked to the SketchUp file or render then as Vector and explode them to create scaled drawing entities.
