Functional Descriptions

On the Piping tab, the Functional Descriptions group contains settings that define what kind of straight pipe parts, curves, and branch parts you use if you route a pipe. Each setting has a default type and optional types that the project administrator has specified in the piping specification. If you select one of the optional types, the setting text is displayed in red to indicate that the currently selected type is not the default type.

For more information on the administrative part, see Functional codes.
