An overview of the Subtypes toolset

The Subtypes toolset contains tools that create and edit subtypes, which provide a method of dividing feature classes or tables into logical groupings based on an attribute value.

One advantage of using a geodatabase to store geographic data is that you can create subtypes for features and attributes. When working with subsets of features in a feature class, you can use subtypes to assign consistent attributes and behavior to the subsets.

Remove Subtype	Removes a subtype from the input table using its code.
