Flip Line (Editing)
Summary
Reverses the from-to direction of line features.
You can view the orientation of line features by symbolizing line features with arrowheads.
Usage
-
Direction-dependent attributes, such as address ranges, are not flipped----only the geometry is flipped. For example, suppose a line feature has an LF-ADD attribute ('left from address') of 100 and an LT-ADD ('left-to address') of 198. These values will not change if the line is flipped.

This tool modifies the input data. See Tools with no outputs for more information and strategies to avoid undesired data changes.
Syntax
Parameter | Explanation | Data Type |

The input feature class or layer. This must be Polyline. | Feature Layer |
Code Sample
This example shows how to use Python stand-alone script to do in-place editing.
# Name: Flipline_Example.py # Description: Flip line features # Requirements: # Author: ESRI import arcpy from arcpy import env env.workspace="C:/data" inFeatures="harvestable.shp" try: arcpy.FlipLine_edit(inFeatures) except Exception, e: # If an error occurred, print line number and error message import traceback, sys tb = sys.exc_info()[2] print "Line %i" % tb.tb_lineno print e.message
Shows, within a Python interactive window, how to use Python command to flip line.
