Merge features into one feature

The Merge tool Merge combines two or more features on the same layer into one feature. You can modify selected features or preserve them and create a new feature. This tool is available in the Modify Features pane.

When you use this tool, consider the following:

  • Features that do not touch or overlap, merge as parts to a multipart feature.
  • The domain merge policy defined by the source geodatabase doesn't affect attributes constrained by attribute domains.
  • To combine features of the same data type from multiple layers, use the Merge geoprocessing tool.
