The stencil library contains pre-built dynamic symbols for creating dynamic system graphics. Use the 32-bit version of Microsoft Visio Standard or Professional 2003, 2007, or 2010 software and the Advanced Graphics Application add-on to modify the symbols to suit the needs of the facility. Some of the dynamic symbols included in the stencil library are Temp Sensor, Supply Fan, Differential Pressure, and Water Pump. In addition to using the symbols included in the stencil library, you can create your own custom symbols and add them to your stencil library.
