I realized about as much after talking to TreeDimensional about it for a while on the phone. He was explaining all the stuff Sean Freeman had shown in the pictures. Thanks to all of you, for the info.
It was nice to see all the information getting thrown at it, good too! The hammering helps to drive the point home. At least I'm not afraid to show what I've done, even if I didn't get it right. I imagine there are several here who'd only post the best of their works, and definitely not their mistakes; but I hope this makes good learning material for other people who see the site. I certainly learn from it.
