Models - Top down or Bottom up?

I smell a false dichotomy....

Michael - it shouldn't matter, it all depends on your own preferances. I like top down 'cos it is more intuitive to me. I first establish UCS's for front, left, right, back, top and bottom. For complex models I start from the front (!) because that's the most common viewing point. Just remember to save your UCS's. For instance, I call my front one "ff" and call it up using a "ff" AutoLisp command. I further save views by number, and call them up using that number, ie '1' for view 1. Such fast shifting of views does away with any concerns about where to start. Kerry.
