HEC_RAS 3.0 Reverse XS direction
HEC_RAS 3.0 Reverse XS direction
(OP)
We produced sections for HEC ras from Geopak, which were reveresed as far as the convention that the sections should be oriented looking downstream. I understand that the orientation of the cross sections is unimportant, as long as they are all oriented the same way, but we will sumbit to the reviewer.
Is there an EZ way to flip the cross sections?

I think my EZ-ist way is to use Geopak's cut DTM profile on each xs section location (I kept them in the DGN file thank jeebus) as flipped, store ASCII and paste into the X xsetion editor...but then the GIS cut lines are still wrong

BTW this is an isolated bridge replacement. The end result of the HEC study is to show that the new bridge WSE is equal to or below the existing

If you maintain convention with regards to your x-section stationing, you will be much better off when you, the reviewer, or any other engineer revisits the model; particularly if you add to the model at a later stage. It might also save you some extreme confusion while trying to do your bridge contraction and expansion calculations.
Theoretically if you document your break from convention in your model development report, you are okay... but who reads the model development report when there are fun HEC-RAS files to dig straight into?
Please note that the latest version of HEC-RAS is 3.1.3, not 3.3, and similarly, previous version 3.1.2, not 3.2!
