Filtering extension fields by sets (Attribute Object Filter)

Filtering extension fields by a set means that different objects can display different extension fields in their Extensions tab. What determines the display of extension fields? The sets that are assigned to extension fields must match the sets that are assigned to each object.

Assigning extension fields to sets is performed in the Attribute Object Filter dialog in the Symbol form. Using this dialog to classify extension fields is the best way to filter extension fields on objects depending on their purpose.
