Catchment Polygon

Can some one guide me how to set a catchment polygon to be accepted in Drainage Network Editor? I created a CAD polygon which is a Super but when I am trying to pick it up as catchment it doesn't accept it.

Thanks

The catchment strings need to be in models specified in the Catchments file (DNE GLOBAL=>Utility Models tab). Each catchment set (1, 2 & 3) has its own model in this file. You cannot assign a polygon from the wrong set/model.

Click on the folder icon and select [Open]. This opens up an editor for the file. Fill in at least one catchment model and press the Write button to save the file.
