Sure Red.
I set up my scenes in SU to reflect typical layouts; Site Plan, Floor Plan, Elevations, Sections, etc...
SketchUp Setup
Each scene has layers that are specific to those scenes for such things as dimensions in plan.
My Floor Plan scene is the only scene that has the layer DIMS-FloorPlan active, all others this layer is hidden and so on.....
That way each scene has its own designated layers showing.....
Layout Setup
Another thing; my title sheet is just set up as follows:
Title sheet linework - locked
Title sheet text - locked and shared across all pages
Title sheet Project text - unlocked so i can copy from one page to another and alter to suit
Model import - I set up a layer called 'MODEL', it is located at the bottom of the layerset to ensure it is under all other linework [LO recognizes layers visually as they are sorted in the layer dialogue box]
Text / Arrows have their own layer as do drawing symbols such as section syms, title syms, etc...
I've also made a scrapbook file of the typical symbols I use for each job
That's pretty much it.
