2. IEEE Std 315 for symbols and reference designators.
3. Zen feng shui a la Tufte.
4. For multi-sheet schematics, provide a list of every reference designator and applicable sheet(s). Use sheet/zone references for all labels that span multiple sheets.
5. In general, functional left-to-right flow tends to be optimal for interpretation. Keep the application intent in mind.
6. Sideways text is never acceptable.
7. Q0O5S2Z1IX...if these characters aren't distinct, your typeface is busted.
8. Minimize net crossings. If you feel cross-eyed looking at any sheet, your schematics are likely busted.
9. Assume black/white printing. If you need colors to disambiguate, your schematics are certainly busted.
10. Electrical schematics convey eletrical intent, mechanical drawings convey mechanical intent. Sometimes it's useful to convey elements of the latter in the former.
