Multiple Ring Buffer won't execute on stream layer created from DEM

Discussion created by smith984 on May 28, 2012
Hello,

I am attempting to apply a multiple ring buffer to a streams layer I created using Arc Hydro Tools 2.0. It will not execute over large or small areas and provides the following error message:

Executing: MultipleRingBuffer south_streams C:\Users\siu850727638\Documents\GIS_files\hydro_by_state\merging\south\south_streamsMRB.shp 1;5 Kilometers distance ALL FULL
Start Time: Sat May 26 02:11:21 2012
Running script MultipleRingBuffer...
ERROR 999999: Error executing function.
Invalid Topology [Topoengine error.]
Failed to execute (Union).

Completed script MultipleRingBuffer...
Failed to execute (MultipleRingBuffer).
Failed at Sat May 26 02:34:54 2012 (Elapsed Time: 23 minutes 33 seconds)

I attempted to repair the layer using the "Repair Geometry" tool and "Multipart to Singlepart" tool, but those did not work--as far as I can tell there are no errors in the geometry. I kept the DISSOLVE ALL option checked because I have not found a way to create the multiple ring buffer lines any other way that worked. I have Service Pack 4 installed.

Any ideas? Thank you!
