Importing Attribute Data
When you import data (as opposed to using
Data Connect (page 303)), the
imported material is converted to AutoCAD drawing objects. As you import
objects, you can import the attribute data attached to the objects.
You can import the data to one of the following:
■ Existing object data table — By default, incoming fields are imported into
object data fields with the same name. If no object data field exists with
the same name, the incoming field is not imported. If you don't want to
do this, use Object Data Mapping to map incoming fields manually to
object data fields with other names or to create new fields.
Incoming data is converted to the data type of the existing object data
field. If this conversion fails (for example, if you import characters to an
integer field), AutoCAD Map 3D uses 0 for integers, 0.0 for real numbers,
and "" for text.
■ New object data table — By default, the fields in the new object data table
match the fields you've chosen to import. If you do not want to do this,
use Object Data Mapping to select the fields to import or to change the
names of the object data 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.
Data is imported only if it is attached to an incoming object. If no objects
are found for an input layer, then the object data table will not be created.
