For a new object data table name, AutoCAD Map 3D creates a new object
data table with fields that match the fields you're importing. To change
these defaults, click Select Fields.
For an existing object data table, incoming fields are imported into object
data fields with the same name by default. If no object data field exists with
the same name, the incoming field is not imported. To change these defaults,
click Select Fields.
When the data is imported, it will be converted to the following object data
types:
■ Integer32, Integer16, and Boolean data types are converted to the Integer
data type. For Boolean data, false is converted to 0 and true is converted
to 1.
■ Float, Double, and Decimal data types are converted to the Real data
type.
■ Char and Date data types are converted to the Character data type.
Incoming data is converted to the data type of the matching object data
field. If this conversion fails, AutoCAD Map 3D uses 0 for integers, 0.0 for
real numbers, and "" for characters.
Select Fields
Select the fields to import and specify names for the object data fields.
Add Unique Key Field
Automatically create a field with a unique entry for each imported object.
You can edit the field name.
The unique ID numbers increment within a single AutoCAD Map 3D session,
but restart when you restart AutoCAD Map 3D. To extend the unique key
across multiple imported files, import them all during the same AutoCAD
Map 3D session.
Add To Database Table
Append data attached to the objects in the source to an external database
table. The links to the data are imported with the objects. Select the link
template to use. Optionally, import only the link data.
If no link templates are defined in the current drawing, the option is not
available.
Link Template
Select a link template from the list.
