In really extreme cases, you may need to delete all of your hdf files (that can sometimes get corrupted) and re-run your plans.In extreme cases, you may need to restart your computer.In most cases, you can solve the problem by closing HEC-RAS and re-opening it.YouвЂ™re welcome! вЂ¦butвЂ¦if it still doesnвЂ™t work вЂ“ the elusive 1 out of 10 times вЂ“ you may need to follow the same troubleshooting steps as with some of the other more pesky HEC-RAS runtime exception errors (such as those that can sometimes occur in RAS Mapper even when the plans have run through error-free): If any of the terrain features that you see in RAS Mapper are still missing in the Geometric Data Editor, try toggling the terrain off and on again using the вЂњSelect Layers to ViewвЂќ icon in the geometry viewer. Zoom or pan in the geometry editor (use CTRL left-click to pan)Д© out of 10 times, these steps will bring back your terrain with the current elevation ranges, contour intervals, hillshade values, etc.:.

Open the geometry editor (leaving RAS Mapper open).Save geometry and close the geometry editor window.If that happens to you, here are the steps to get it back:

Sometimes even when youвЂ™ve got your associations and view options set correctly, however, the terrain that you can readily see in RAS Mapper will be missing in the Geometric Data Editor, like in this screen shot: The steps IвЂ™ll list below assume that:ДЎ) your geometry file has already been associated with the terrain you want to view (Right-click on Geometries in RAS Mapper and then left-click on вЂњManage Geometry AssociationsвЂќ, select the current terrain file, and click вЂњCloseвЂќ)Дў) you have toggled on вЂњPlot TerrainвЂќ when you click on the вЂњSelect layers to view in backgroundвЂќ icon

There might be a simpler way to get around this little glitch (IвЂ™m open to any suggestions!), but IвЂ™ll go ahead and post the method I use to get my terrain to re-appear (or to refresh with the latest changes youвЂ™ve made in RAS Mapper). It happens to most attendees of the courses I teach, so I always write the workaround steps on the whiteboard before we even start a class. After you've downloaded the new version, make sure to give the release notes a. HEC has just released HEC-RAS Version 5.0.6. Chances are, if youвЂ™ve been using HEC-RAS for a while, youвЂ™ve had your background terrain disappear in the Geometric Data Editor.
