This question already has an answer here:

I am trying to merge several polygons in a feature dataset into one. Normally I would use a simple merge but the issue is that merge automatically dissolves. I on the other hand want to have them all represented by one single record, but maintain their existing boundaries.The top image is what happens. But the bottom image is what I want. As mentioned originally the left would represent by two separate selectable polygons and the right is the output being one record/one selectable polygon.

This is what happens when you merge. One record is created from two existing records.

This is what I want to happen. I want to merge the two together but maintain both polygons entire existing boundaries. Although now I want it to be one record

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • Topologically speaking, what you ask isn't possible. Parts can't overlap. Even if you could generate such a shape, it wouldn't render correctly, and attempting any sort of operation on it would cause spectacular failures, far worse than having a ring not wound in the correct direction. – Vince Sep 20 '15 at 3:18

    Reference: portal.opengeospatial.org/files/?artifact_id=25355 a) The interiors of 2 Polygons that are elements of a MultiPolygon may not intersect. You can express your geometry as GeometryCollection but I do not know if ArcGIS can handle those. Example: GEOMETRYCOLLECTION ( POLYGON (( 418 357, 418 359, 420 359, 420 357, 418 357 )), POLYGON (( 419 356, 419 358, 421 358, 421 356, 419 356 ))) – user30184 Sep 20 '15 at 12:08
