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 that modify or update the input data 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.

• When input is a feature layer with a selection, only selected features will be modified.
