To Exchange Information Across ActiveX Object Models (ActiveX)

Other programs that support ActiveX can communicate with AutoCAD using the AutoCAD ActiveX API.

1. Reference the other applications' ActiveX Object Model.

   This will make your code aware of the names and relationships of the objects in the other Object Model.

2. Create an instance of the other application.

   This will create (instantiate) valid objects for the basic objects in the other Object Model.

3. Write your code utilizing both the AutoCAD Object Model and the other applications' Object Model.

   This is where the exchange of data takes place.
