I am developing a Trapezoidal Canal for a college homework, but I’m having problem to export my assembly to hec-ras. When I click on Export to Hec-Ras it asks me to select the river banks, but when I select my geometry it says that there is no polyline.
What am I doing wrong?
How should I proceed?
Hi Igor. You need to create sample lines and sample the surface of your channel. Only then you can export it to hec ras. As for selecting bank lines it is optional you dont have to define it to export geometry.
