Object data allows you to create a simple database in a map and store text and numeric data in your maps directly attached to any object. It is far more powerful than block attributes because object data works with any object, not just blocks. Use object data tables to save any kind of information, run queries based on information in the tables and to create thematic maps. Object data can associate an object with documents from other applications. However, Autodesk Map works with object data created only in Autodesk Map and does not recognize object data from other applications, including AutoCAD®.

To use object data, define the format for the table, and then create records in the table to attach to selected objects.

When editing objects, keep these points in mind:
• When you edit an object with object data using the BREAK or TRIM command, and break the object into multiple segments, the object data remains with only the one segment that contains the start point of the original object.
• When you copy an object that has object data attached, the object data is also copied.
• If you place an object with object data inside a block, the object data remains attached to the object that is placed into the block. You can access the object data by selecting the Nested Data option in the Edit Object Data dialog box
