Hi brianafischer,
We do not provide any tutorials or examples using the pneumatic (PNEU_ISO125) libraries in AutoCAD Electrical 2006. The workflow for inserting pnuematic symbols is similar to that of the JIC demo.
From the Help: "The default symbol subdirectory, jic1, and a companion 0.125 uniform text height library, jic125, each contain hundreds of component symbols in standard AutoCAD ".dwg" file format. These are referenced by AutoCAD Electrical and its icon menuing system and are inserted as standard AutoCAD blocks with attributes."
You can follow the Getting Started guide to insert symbols in any of the symbol libraries you mentioned.
Thanks,
Heather Schwartz
