How do I create HEC-RAS cross section with 0 sta at center
How do I create HEC-RAS cross section with 0 sta at center
(OP)
HEC-RAS newbie here.
I am trying to create a HEC-RAS cross-section with 0 station at the center of the stream.
I draw the cross-sections in Bentley Microstation and then use inroads to export to HEC-RAS.geo file.
How do i get the cross sections so that everything left of the stream has a negative distance and everything to the right has a positive distance?

so there is really no straight tool to do this other than manually entering the xsections stations yourself.
Also, in HEC-RAS Cross Section editor, what is the "Downstream Reach Lengths" meaning.
I imported my x-sections and some of those values are 0. I get error message when i try to run it that the LOB, ROB has to be greater than zero.

If you're getting zeros on downstream reach lengths, chances are good that you have to cut 3 profiles down the creek, not just 1. One for left overbank, one for right overbank, and one for centerline. You should spend some time reading what HEC-RAS actually does before going any further. It's a complicated piece of software, and there's a lot of nuance to it.
