How can edges and their respective faces live on separate layers? That's just crazy.
If you heed Google's directions for using Layers, faces and edges are supposed to be on the same layer, Layer 0. It's only components and groups that get other layer associations.
True. But it's just not an intuitive tool, unline pretty much everything else in SU.
The whole Outliner/Layers metaphor in SU is odd.
The Outliner actually works more like the Layers palette as found in apps like Photoshop. But otherwise works well.
The Layers palette just annoys me. Why no sub menu to see what each layer contains?

There really should be something like a wiki to organize and show examples for ALL the plugins living here.

It fixes a rare potential 'PI' glitch if you don't have certain other scripts installed...
Thanks!

It allows you to make 2D Perspective views. Vertical lines in the model will be shown as vertical while horizontal lines will recede toward vanishing points.
So it's more for making printouts/presentations than for modeling?

I haven't found a non-destructive way of achieving this effect.
If both the objects are groups/components - select them both and choose Intersect > With Selection. The edges are then created in the current context and not inside the groups.
Not the result I would have expected from that command! Thanks!

Is there any way to have a line show where to components intersect each other (as indicated in first photo)? Sometimes it would add a little visual interest to a project.
Like this?

Very clever Jeff.
Much appreciation for all the hard work here.
I don't really have a practical need to get this level of precision/accuracy but problems like this totally consume me.
I figured the faster I could figure it out it the sooner I could move on to more important things! (or not)
SketchUp is an amazing piece of software and maybe one day I'll have a more concrete use for it. 
Not that anyone cares anymore but here's a my proper 2D method...
Thanks Tig. You're a genius. 
Hey what happened to all those steps you wrote out Tig? 
Anyway I guess the circle approximation is the best we can do...
Thanks everyone
Thanks for the detailed reply Tig.
Unfortunately I'm having trouble figuring out the proper sequence of steps to follow your instructions. 
I can easily create a version of this by rotating the top face of a cube by 45° and tweaking a few lines.
However the resulting triangles are not equilateral, which is what I'm after.
Any ideas?
Thanks
*PS
Anyone know a way to construct polygons in SketchUp starting only with their "Nets".
Without knowing the specific folding angle I haven't been able to do this precisely.
