Using ArcGIS Desktop, 10.5.1, I need to "explode" a singlepart polygon FGDB Feature Class into separate FCs.

For example, if the input FC contains 3 polygons, the output will be 3 separate FCs, each containing a single polygon.

I am using the Split By Attributes tool.

How do I split by the input FC's Objectid field?

When I open the tool, it does not include the Objectid as an allowed Split Field:

One solution would be to create a new field named ID or something similar. Then Calculate Field and set it equal to OBJECTID, which does show up in the field calculator. Then you can use the new ID field as the Split Field in the Split By Attributes tool.

  • This works! FWIW, I find it odd that OBJECTID isn't available "out of the box"...

  • Yeah, me too. I've run into this same problem for a few other tools too. Creating a second ID column always seems to do the trick.

Create a new field and populate with your OBJECTID values, then split by that field
