Set Flow Direction (Trace Network Tools)

Summary

Sets the flow direction of line features in a version 1 trace network.

Usage

  • Flow direction can only be set with Set Flow Direction tool for line features that participate in a version 1 trace network.

    Legacy:

    The Set Flow Direction tool is not supported with Trace Network Version 2 or later. Use the FLOWDIRECTION network attribute field to set or modify the flow direction of a line feature in the network.

  • The network topology must be enabled.

  • Flow direction can be specified at the feature level with digitized direction, against digitized direction, or as indeterminate. When a selection of features exists on the map, the flow direction will be set for only those features.

Parameters

Label Explanation Data type

Input Trace Network

The trace network that contains the line feature class on which the flow direction will be set.

Note:

This parameter requires a Trace Network Version 1 as input.

Trace Network; Trace Network Layer

Feature Layers

The polyline features that participate in the input trace network.

Feature Layer

Flow Direction

Specifies the flow direction of the edges.

  • With digitized direction—Flow direction will be along the digitized direction of the edges.

  • Against digitized direction—Flow direction will be against the digitized direction of the edges.

  • Indeterminate direction—Flow direction will be indeterminate.
