I am encountering an error while using the Arc Hydro tutorial and on my own data.
Upon running the Build Walls tool, I receive the following error which appears to be failing on converting a string to a double somewhere in the VB code for Arc Hydro. I have turned off background geoprocessing and followed the recommended steps in the Arc Hydro Problem Solvers thread.
Any help would be appreciated.
The CreateFeatureClass command works. Then it runs
PolygonToRaster which also succeeds. The result looks like it creates a raster of the flowlines.
Then it fails on Build external walls.
