Orifice tool

Orifice tool

This tool, , is used to draw multiple outlets from detention basins, even when these are subject to tailwater influences. Like the weir tool, it is only available with the Full Unsteady hydraulic model.

These objects link a detention basin to a pit or node. The link can be bent to allow more than one weir or orifice to go between the same end points.
