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

Caution:

This tool modifies the input data. See Tools with no outputs for more information and strategies to avoid undesired data changes.

• 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.

Syntax

FlipLine_edit (in_features)

Parameter	Explanation	Data Type
in_features	The input feature class or layer. This must be Polyline.	Feature Layer

Code Sample

FlipLine Example(stand-alone script)

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
