(WORKAROUND: Fortunately this is another easy fix scroll to the “paperspace” paragraph here for the steps.)

View snaps to origin. The geometry file can jump to the origin if you save before adding features.

(WORKAROUND: If saving, closing, and re-opening doesn’t do the trick, the only way I’ve found around it is to delete the hdf files associated with the geometry and results and re-run the plan.) RAS Mapper can freeze with an unhandled exception error when plotting time series, which sometimes occurs due to corrupted hdf files. By far the #1 complaint in our courses is when the background terrain disappears in the Geometric Data Editor. (WORKAROUND: Luckily it’s a fairly easy fix here are the steps.)

Some of these items have already been addressed in more recent versions, so this list is currently outdated – I will replace it with a new list once I have finished testing the new beta Version 6.0. The idea behind this list is to provide workarounds or updates on fixes for course attendees wherever possible rather than serving as a complaint board so if you have figured out a way around one of the listed issues, please let me know how you’ve managed, and I’ll update this post.

Sure, I’m just one user, but these are ranked by level of supplication or frustration based on input from hundreds of course attendees, so this particular list comes quite a bit of group consensus weight behind it! The RAS Solution Forum has existing threads for HEC-RAS bugs and suggestions, so there’s no need to post a comprehensive list of proposed fixes here, but I thought I’d list some of the items that come up most frequently during our HEC-RAS courses. Course attendees are consistently impressed with the user friendly functionality and how quickly they are able to create and animate a model from scratch that said, however, certain glitches and limitations are repeatedly mentioned as potential improvements for future releases. We’ve had a tremendous response to the new features in HEC-RAS 5.0 in the courses we’ve held across Australia and New Zealand over the last year or two.
