Hi Chris
Thanks for your respond
Is it possible to change flow direction of the drainage? The flow direction is incorrect in my drainage.
I have created new profile and when I try to change the structure in the profile this error message comes every time. If I try to change it through edit / review > Apply...and update drainage profile the same error message comes again. If I delete the drainage network from the profile and redraw it, it comes with changes included.
regards
Sigfus
