NOTE To make selections in the Object Class column, first define object
classes in the AutoCAD Map 3D drawing. If there are no object classes defined,
the fields in the Object Class column are grayed-out. For more information,
see
Setting Up Object Classification (page 116).
3 For each layer in the incoming file, click in the Object Class field.
4 Select an object class.
5 Click
to map incoming attribute data to the AutoCAD Map 3D object
class definition.
6 In the Object Class Attribute Mapping dialog box (page 1710), verify that
the object class you just selected is highlighted in the Select An Object
Class list.
7 On the right, review the Input Fields list, which displays the incoming
attribute data fields that are available to be mapped to Target Fields in
the object class definition.
8 For each Input Field to map, click the down-arrow under Target Fields,
and select a target field in the object class definition. The syntax used for
the target field is:
CATEGORY:TABLE:FIELD
■ CATEGORY — Type of data, for example "OD" for object data, or "LT"
for link template (linked external database).
■ TABLE — Object data table name or database table name.
■ FIELD — Data field name.
After you map a target field, it no longer appears in the Target Fields list.
This ensures that each target field is mapped to only one incoming data
field.
9 Map as many of the Target Fields as needed. If there are no more target
fields in the Target Fields list, you've mapped them all. If you do not map
a target field, the default object class value is used.
10 Click OK to close the Object Class Attribute Mapping dialog box.
11 To use object class default values for incoming data values that are not
within the specified object class range, select Use Class Defaults For Out
Of Range Values. Properties such as Layer and Color are also enforced.
