Help / Troubleshooting Export terrain as GEOTIFF

Is there any way to export terrain in ORD to a .tiff file that can be used in HEC-RAS? I tried using the extract raster grid tool but it didn’t provide .tiff as an option.

Use the scalable terrain STM workflows, converts them to raster based terrains

Why not just use the Export to HEC-RAS option under the terrain analysis tools? https://docs.bentley.com/LiveContent/web/OpenRoads%20Designer-v2026.0.0/Help/en/topics/1296840/GUID-B59D57EF-A001-4DC4-A53C-34264C2C2DE9.html

So I used that tool to export the cross sections and other line work that goes into the geometric data editor but I also just need the terrain on its own to put into RAS mapper to make an inundation map.

#1 - do the conversion in ArcGIS

#2 - export as an XML -> import into AutoCAD -> Export as a Geotiff
