Hello,
I’ve developed a river reach in ArcGIS with about 52 cross sections. I’m using the HEC-GeoRAS tool to create a hydraulic model. Following the user’s manual I created an import file of the format .sdf. When I open HEC-RAS and try to import this file, I get an error message.
A few more notes on the process – I open HEC-RAS, create a project name, and then attempt to add the GIS Import file (**.RASImport.sdf) into the Geometric Data editor. The Import Geometry Data window opens up and then when selecting the import options, under River and Reach Stream Lines tab I click a check box to select the river. I noticed that “# Points” is zero. Next I click the Cross Sections and IB Nodes tab, which instantly returns the message “Run-time error 9: Subscript out of range.” Clicking Okay to this message immediately closes the entire program.
Any thoughts?
