Then I put these guides on a separate layer whose visibility you can turn off any time. Guides are handy for other reasons, too, as their visibility can be toggled on/off in the View menu globally as well as you can delete all construction geometry (when finished and they are not needed any more) in the whole model from the Edit menu (although keeping them on a separate layers can always be better as you may need to revise your model later)
That gives me an idea, I could add something (on a separate layer) to aid the layout process and turn off that layer later....

Still not sure if this is what you need however... [/quote]

Brilliant! The simplest things are always the best! The ovals are on their own layer for final presentation, etc. Check out the .skp, works best in Front View. Thank you!
It would be interesting to be able to prevent a surface from passing through another, make it literally solid. Perhaps in Version 12.
