If the box is not selected, the object will have two values assigned for the
data fields in the table.
Select the box when you want only one set of values attached to the object,
as when specifying a pipe diameter or a desk height. Clear the box when
the object can have multiple sets of values assigned to it, as when specifying
software installed on a computer or types of plants in a landscape section.
Define
Display the Define Object Data dialog box, where you can create new tables
or modify existing tables.
To attach data to an object, select a table and review or change the default
values. Click Attach To Objects. When you finish selecting objects in your
drawing, AutoCAD Map 3D creates a record for each object and attaches the
records to the objects.
If you selected Overwrite, the new record replaces any existing record from
this table. If you don't select Overwrite, the object can have more than one
record from the table.
To detach data, select a table. Click Detach From Objects. When you return
to your map, select all the objects you want to detach the data from.
