12d Model

following my previous question about catchments I have two more question I will appreciate any one shed some light on. 1- How one should define the downstream boundary conditions such as downstream flood level for entire reticulation. In other words where in 12d we are able to define all the network...

all sweet
thank you very much

thanks for reply
how should I create a *.catchment file?

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

Thanks mate for tour help.
I sent you my project. I think I successfully modelled my car park but there is some issues which you may see if you open the project. it is mainly that there is discontinuity through the super Tin (Tin Design) which consist of my Tin nat and Tin carpark.

Hi all
I am modeling a carpark which is a flat/semi flat platform. How can I model it using Super Alignment?

Thanks
