Process Flow Sheets with ControlDraw

Did you know that ControlDraw can produce Process Flow Sheets that show process flows and the material properties for equipment and lines. This is achieved by using Symbol Data - name value pairs that you can set for each symbol, or by a matrix.
An example and explanation is provided in the latest Sample Models.
And of coure, like pretty well everything in ControlDraw (and unlike say Visio) the data becomes available for use in Queries and even calculations.
