JoAnn,
 KISS may not work for you on this one. For that matter KISMIF(keep it
simple make it fun) may not also.

First I am not familiar with your cad system to offer more than just a
thought process.

The cad system I have used for the past 15 years is dumb in this area. So
we had to make some decisions regarding what information needs to be
represented on the schematic. This is our approach :

  1. All inputs to the schematic sheet are located on the left edge and
represented by an arrow pointing in
  2. All outputs are located on the right edge and represented by an arrow
pointing out
  3. The source of the signal leaving the page will identify all pages of
destination
  4. The signals entering the page shall have the origin page represented
  5. All signals leaving or arriving on the sheet shall have their net name
visible
  6. Zone id's are optional and at the mercy of the engineer.

Our corporate sheet standard does not allow for zone ID. SO #6 usually is
not a main item.

Our main schematic sheet size is a small "E".  The schematic plot is done
on a "B" size laser,(HP4V). This yields a very readable print that can be
3-hole punched and fan-folded to fit in a standard 3-ring binder.

I hope this helps some.

As a note of interest, the next release of our current CAD software will
have a module that will do this notation automatically.  That should be
interesting.
