At a more advanced level maybe this series of books also could be useful: http://sketchucation.com/shop/books/30-intermediate/180-the-secrets-behind-car-modeling-in-sketchup-part-1-of-3

@dave r said: I was in the process of making a graphic example. I'll post it anyway. [attachment=1:3hulq9iz]<!-- ia1 -->Ovoid Perspective.png<!-- ia1 -->[/attachment:3hulq9iz] [attachment=0:3hulq9iz]<!-- ia0 -->Ovoid Parallel.png<!-- ia0 -->[/attachment:3hulq9iz] As you can see, it would be much easier to select all of the geometry for half of the shape or any other amount in the second view than in the first. Definitely. And I admit, that's part of what was originally giving me trouble when I initially tried this. Much appreciated.

I scrapped my original chassis and started over. I think this one is marginally better. At least, I'm getting used to making components and cutting them to fit. Here it is. I've no idea why the closest corner pieces show the blue side. I reversed faces and all kinds of things trying to fix it. Overall, I'm shooting for maximum torsional rigidity through the red axis, while keeping weight down.

It seemed to work fairly well, though it's tough to get a good view of it without being able to orbit around a bit. I used it on the front "forks" on either side of the cockpit.
