"I have pretty much mastered the technique of hierarchial layers and the rare use of deliberate cross layering. They are fundimental in every drawing I now make. I have no "organizational mess" with ALL geometry on layer0, and ONLY outer groups and comps on other layers. Far from that, it is a far simpler way to make organizationl/ hierarchial layer changes than any other way I've encountered."
Which is probably right. At first glance it looks like a solid organisation.
In abundance, here's another way of organizing things for a particular use. Not quite the way I use it, although there are a number of similarities. Maybe this is usefull for "full solid" 3D modeling, where you don't only model the outer skin.
