    So we are in the pipeline industry of course, and I have multiple clients who need to rotate line symbols for utilities crossings against their pipeline centerline.  I know I can rotate a symbol based on a DB field and against north straight up with the ESRI rotate option, however we need to rotate the symbols against the centerline itself.   I did find a utility tool that my client runs on a nightly basis, however this is extremely cumbersome sine the have 100’s of thousands of events.
