Attaching Data
You can link data to objects as you digitize. Although you can store data in
AutoCAD Map 3D as block attributes, you can perform more sophisticated
analysis of the data if you use one of the following methods:
■ Data linked to an object is stored as object data in the drawing.
■ Data linked to an object is stored in an external database.
