Plumbing line styles and plumbing fitting styles, respectively, determine the appearance and function of plumbing lines and plumbing fittings. For example, a plumbing line style determines how a plumbing line is displayed when crossing other plumbing lines, its available nominal sizes, and its display properties.
This section provides information on styles specific to plumbing. For general information that is applicable to all building systems disciplines, including plumbing, see Styles.
