Steve, I understand where you're coming from, but I've found that beginners often have a harder time visualizing what you and I may take for granted. I present finished plans to demonstrate what is possible within the modeler's parameters; it's no different from thumbing through a book of track plans, except that mine are a better fit for their specific needs. They don't have to build what I offer, but giving them a more concrete starting point helps them get their feet wet more quickly. Although it can, a modeler's first layout doesn't necessarily have to be a lesson in layout design, IMO. As they grow and progress, they'll come to learn track planning fundamentals--assuming they want to.
