Merge Network Features


Description:

The merge network features command merges network edge features allowing the transfer of attributes from one of the merged features to the other. The command is designed to be similar to Merge Features command available in the ArcMap Editor within ArcGIS Desktop. The command also supports merge domain constraints. For coded value fields, it will assign the default value to the new feature. For range domains, there are three choices: default value, sum and weighted average, it will assign the value based on the specific choice. For complex edge features, the command re-establishes connectivity at mid-span with junction features. Known Limitations: The command does not support the user of Group Layers. If group layers are present in the Map Document, the command will fail with an error message.
Products:
ArcEditor: VB6

Platforms: Windows

Requires: An edit session with network junction features

Minimum ArcGIS Release: 9.0

How to use:
  1. Double click on the _Install.BAT file.
  2. From the 'Developer Samples' commands category, add the 'Merge Network Features' command to the Editor toolbar.
  3. Load a geometric network and start an edit session.
  4. Set the Target Layer to an edge feature class, the 'Merge Network Features' command will create the merged feature in this feature class.
  5. Select two or more connected network edges from the same feature class.
  6. Click the 'Merge Network Features'.
