Custom Features

Created:1/11/2001
Description:

The CASE tools allow you to create custom features that extend the data model of ArcInfo 8. Object-oriented design tools (OOA&D) can be used to create object models that represent the design of your custom features. These tools make use of the UML to create designs. Based on these models the CASE tools will help you create Component Object Model (COM) classes that implement the behavior of the custom features and database schemas in which custom feature properties are maintained.

The CASE tools consist of two major activities: code generation and schema generation. The former is used to create the behavior, while the latter is used to create schemas in geodatabases. In this tutorial you'll create an object model with custom features, create code adding custom behavior, and create a geodatabase schema.
