I have a problem displaying terrain in Lateral Struture Editor. After I added a new lateral structure with unique river stationing there is no plot of the cross-sections in the vicinity of the lateral structure. Does anyone know where I get wrong?
Make sure that your Lateral Structure is connected to your 1D area and that LS is long enough to cross 1D Sections.
This way you should view your XS in the Lateral Structure editor window.
It must be a lack of data.
If you want the HEC-RAS to display your 1D domain from Lateral Structure editor window, you also have to define the (station,elevation) table wich actually define the length of the Lateral Structure.
