Nick mentioned the same things I was thining of (1st time user, or some previous experience).
If 1st time, we can try to guide you through a few simple steps, which should get you somewhat comfortable with the basic "how-to's" and such.
If you have some experience (have at least drawn a Rectangle in AutoCAD), then things may be much easier on both sides.
Feel free to ask away. If you wish to contact me directly, feel free to do this also.
Would be nice to cover some basics (maybe a few advanced things too) in this thread - makes for interesting reading!
Glad you are offering asistance with CAD Q's!
With the two of us posting information, Bren should be able produce the Network Drawings really soon... and maybe with some tossed in AutoLISPs!...
