Downspout Connection
Place a downspout connection object where a roof downpipe ties into the site drainage, and set its diameter in the Inspector.
Downspout ConnectionA Downspout Connection marks a gutter downpipe connection in a drainage plan. Its diameter and notes describe the intended fitting; the symbol does not calculate roof runoff.
Place the object
Open the Water Add panel and expand Surface Collection. Choose Downspout Connection, then click its position on the plan. The tool guide also provides Name and Position entry. Press Esc to stop placement.
Edit its properties
Open Downspout Connection, enter Diameter and add Notes. Diameter is a unit-aware length field, not a fixed millimeter-only text box. Use the displayed metric or imperial units, or enter an explicit unit.
Position and identify it
Use General → Name to identify the object and Location for its position. Length fields follow metric or imperial project settings. Locked objects cannot be edited until unlocked. Changes use drawing history.
Document the route
Draw the appropriate irrigation or drainage pipe route to show the intended arrangement. A nearby symbol alone is not proof of a working connection or a hydraulic calculation. The water tools document a schematic plan; they do not simulate real pressure or flow.
