Use of inline Structure Outlet Rating Curve

[JEM]

I am trying to enter an inline structure in the new HECRAS 5.

My confusion is on the use of the outlet RC. Will the flow based on the outlet RC be additional to what flows (internally calulated) over the weir using the weir coeffcients and equations?

If so, what if i prefer using a rating curve instead of the weir equation. Can i just make the weir coefficient zero so only the RC is used? Will it work?

Or will the calculation just ignore the weir coefficients and instead use the RC when the RC is provided?

Ok, i found out that the RC is just additional outflow from the structure.
