A few other things I’ve found useful. Set up your scenes in SketchUp to show the camera positions you need in your LO document. Avoid doing anything that modifies the Camera settings in LO (results in a dark gray background in the Camera section of the SketchUp Model panel).
Keep your SketchUp models clean. Purge unused stuff from it.
Create layers in your LayOut template based on the type of content. Keep dimensions, labels and other text on layers different from and higher in the Layers list than the layers for your viewports.
These are the layers for one of my LO templates.
Art text is for labels and such. Break lines, Dashed lines, and Hatches are for drawing entities created in LO.
The Model layers are for SketchUp viewports. Multiple layers for them because I frequently stack viewports. The Model layer is set to be active by default so when I send to LO from SketchUp and choose this template, the first viewport will be on this layer.
This template prints on Arch E paper and my client supplies the printed copies folded up so I added fold lines to help me figure out where to avoid putting important details. It gets turned off before export.
The last three layers are for title block and border elements.
