To use data from an external
data source, attach the data source to the drawing. When you attach
a data source, it appears in the Map Explorer tab
of the Task Pane along with the tables
and database queries associated with it.
For the following data
sources, AutoCAD Map 3D automatically creates the files it needs to
communicate with the data source:
- .xls (must have at least one named range)
For other data sources,
you must manually
create the files before you can attach
the data source.
You can set
an option to have AutoCAD Map 3D prompt you
for the database version each time you attach a data source or you
can specify a default version.
AutoCAD Map 3D stores the UDL (Universal Data Link) files
in a specific directory. If it does not find a UDL file in this
directory, it creates a new UDL file. You can change the directory
used for UDL files.
