Batch Merge Feature Classes

EricStarn3 — Tue, 24 Jul 2018 19:45:31 GMT

Hello All,

I am trying to merge several feature classes together via model builder. All feature classes are stored in same work space GDB. What I want to do is iterate though that GDB, because number of feature classes in GDB are subject to change, and then merge all feature classes together. Any ideas how to handle this logic?

Respectfully,

Eric

This is what I was trying. I know I am missing something because it just overwrite the output feature class to the last feature class in the GDB

perhaps you need 'collect values'

Collect Values—Tools | ArcGIS Desktop

Examples of using ModelBuilder utilities—Tools | ArcGIS Desktop

From

Utilities—ArcGIS Pro | ArcGIS Desktop

The Collect Values tool is designed to collect output values of an iterator or to convert a list of multivalues into a single input. The output of Collect Values can be used as input to tools like Merge, Append, Mosaic, and Cell Statistics.

since you basically just need a list of the featureclasses to merge.

Hope the field mapping is identical as are the featureclass types, otherwise you are going to have issues.
