When I am adding inline structure in HEC RAS geometry, the editor is not showing the upstream cross-section after providing the station number. When I tried to give weir details and save the geometry, it shows an “error determining the interpolated cut line”. The added structure disappears. I am not able to add any inline structure across the river.
What is the reason for such an error? How do I rectify the same?
That means your station number does not fall in line with the upstream and downstream cross section ID’s. The number selected must be in between. i.e. US XS = 50 DS XS =49 Inline Structure must be something like 49.5 or any number between the two
Thank you, Luis. I figured out that the error was caused due to the lateral structures. I tried to add an inline structure in between the cross-sections already connected using lateral weirs. When I removed those lateral structures, the error got suppressed.
