You add plumbing lines using the plumbing line tool palette, ribbon, or the Styles Browser palette. You can search, import, and add plumbing lines using the Styles Browser palette. Use the Properties palette to set other properties of the plumbing line.
Note: As you draw plumbing runs in plan view and change the elevation, the software inserts an elbow down drop symbol when needed to represent the vertical segments in the run. You can manually insert an elbow up plumbing fitting if needed at the end of the plumbing line.
