The tool failed while processing geometry. Some of the input features may be invalid or there may be issues with the spatial reference being used for processing.
Verify that the spatial reference used for processing is using default properties for its coordinate system. If the xyResolution and xyTolerance properties of an input's spatial reference have changed from their default values, internal geometric calculations using the altered spatial reference properties may result in invalid output or failure.
After verifying that the spatial reference is valid, or fixing it if needed, use the Check Geometry tool to evaluate whether the input has invalid geometry. If any geometry problems are found, use the Repair Geometry tool to correct the problems and rerun the tool.
