How To: MERGE adjacent polygons in Edit Tools and control the attributes of the new feature

Summary

The MERGE tool in Edit Tools can be used in two different ways to combine adjacent coverage polygons into one new polygon and control the attributes for the new feature.

Procedure

  • Method 1
    Merge two polygons and maintain the attributes from the polygon that is selected last.

    1) Display the polygon coverage to edit in Edit Tools.

    2) On the Edit Polygons menu, click Merge.

    3) Select two adjacent polygons. The new polygon will have the attributes of the last polygon selected.
  • Method 2
    Merge two or more polygons and specify the input polygon attributes that will be maintained.

    1) Display the polygon coverage to edit in Edit Tools.

    2) Select the polygon from which the attributes are read; these attributes will be assigned to the new merged polygon. Click 9 on the keyboard to stop the feature selection task.

    3) On the Edit Tools menu, select ArcTools > Commands.

    4) In the Enter Command dialog box type NEW and click Enter on the keyboard. This command moves the selected polygon attributes to the attribute buffer.

    5) On the Feature Selection menu, select the Remove radio button and click All. This will clear the selected set of features.

    6) On the Feature Selection menu, select the New radio button and select the polygons to merge. Hit 9 on the keyboard to stop the selection task.

    7) Click Merge on the Editing Polygons menu. The new merged feature will be attributed with the values stored in the attribute buffer.
