Importing MapInfo MIF/MID Files
MIF/MID is a file standard used by MapInfo, a desktop mapping system.
AutoCAD Map 3D supports MapInfo up to version 7 MIF/MID files.
About MapInfo MIF/MID Files
MapInfo MIF/MID format stores both geometry and attributes (data) for
features, and is a set of two physical files that work together:
■ .mif— Vector geometric data. A single .mif file can contain many different
types of geometry.
■ .mid— Attributes for the geometric data.
Importing
MapInfo MIF/MID files can only be imported (and exported). They cannot be
accessed using Data Connect. By default, AutoCAD Map 3D considers MapInfo
MIF/MID a multi-select, file-based format, that is, you select one or more
individual .mif files during a single import process. To change the default so
that AutoCAD Map 3D considers MIF/MID a folder-based format (all files in
the folder are included in the import) or a single-select format (only one file
can be selected for import), modify the settings in the mapimport.ini file.
When you import MapInfo MIF/MID files, it is important that you have both
the .mif and .mid files in the same folder.
Symbol types are similar to AutoCAD Map 3D point objects. You cannot
import MIF/MID symbol types directly. However, if you store the symbol type
information in a column in a MID file, you can map each symbol type to a
block in the current AutoCAD Map 3D drawing. To do this, prepare the MIF
file by putting the name of the symbol type into a field in the database. Prepare
the AutoCAD Map 3D drawing by creating similar symbols as blocks in the
AutoCAD Map 3D drawing. Then, during import, perform a point-block
mapping and select the check box to get the block name from data and select
the symbol type field you created.
