A recent tech support call concerned defining Rise and Drop symbols with Revit pipe and ductwork, so I thought I would share the process.
Just a few steps are required:
Firstly, determine the ‘System Type’ used. Armed with this information, expand the ‘Families’ heading within the Project Browser, drill down until you find ‘Piping’ or ‘Duct’ Systems (whichever is appropriate) depress your mouse right button over the relevant system and select ‘Type Properties’.
Locate the Rise/Drop Heading and choose one of several predetermined symbols.
In use, any pipe or duct that extends above the views ‘View Range Top’ property will be shown with the Rise symbol, any pipe or duct located within the views ‘View Range Top and Bottom’ property will be shown with the Drop Symbol.
Presently, the Rise/Drop symbols are not user defined, so if any custom symbols are required, they will have to be defined as ‘Detail Components’ and placed in the view at the relevant location.
