We usually model closed gates as sluices, as they are the ones that can easily be closed (by setting the height to zero). The downside of this is that it can only be a rectangle (and it usually closes off a round pipe). An orifice now has the nice option to set it at either circular or rectangular, but closing it is not possible (setting the flow limit to zero would make sense here, but doesn’t work). Is it possible to do something about that? In WSPro you have the nice checkbox Close Pipe for all objects, that would come in handy in ICM as well.
