Some of the defaults
for import and export settings are stored in .ini (initialization)
files. When you use a new format with AutoCAD Map 3D, the information
about that format is added automatically to the .ini files.
However, in some instances, you may want to modify these files yourself.
In addition, you can set some formatting options in these files.
You can modify the following .ini files:
- mapexport.ini — Set options
to export a file-based format as a folder based format (which is
especially useful for Shapefiles); to specify how to segment arcs
and circles; to define the default seed file for exporting DGN files
(which determines defaults such as units of measure and 2D vs. 3D); and
to specify language encoding settings for exporting GML data in Asian
- mapimport.ini — Set options
to use for file or folder selection; to set default import options
for DGN; to import object colors to their RGB (True Color) equivalent;
and to specify language encoding settings for importing GML data
in Asian languages.
- mapforeignfileproperties.ini — Set
options to specify linetype, line weight, font, and justification.
Exporting to ArcView Shape
If you are exporting
to ArcView Shape files, you can treat
it as a folder-based format. To do this, you must modify the following
items in the MapExport.ini file:
- Specify that it requires a folder rather
than a file.
- Specify that it requires a prefix name.
- Specify that it no longer requires a
If you modify these items,
be sure to modify them only for a driver that supports this change.
Segmenting Certain Entity
Types When Exporting
When you export Splines
and polylines with bulges, they are broken into polyline segments.
The SegmentationDegrees option determines the number of degrees
used for segmentation. By default, SegmentationDegrees is 2 degrees.
In addition, when you
exporting to a file format that does not support arcs or ellipses,
such as Shape or Coverage, or does
not support ellipses that have axes at an angle, such as MIF/MID,
you can further modify the segmentation by changing the value for
FME_ARC_DEGREES_PER_EDGE. By default, FME_ARC_DEGREES_PER_EDGE is
You can change SegmentationDegrees
and FME_ARC_DEGREES_PER_EDGE to be larger or smaller.
Exporting to MicroStation
When exporting to DGN
files, AutoCAD Map 3D reads a seed file to determine default information,
such as whether the destination DGN file is be in imperial units
or metric and whether the file is 2D or 3D. There are separate seed
files for DGn version 7 and version 8. For more information about
seed files, see MicroStation Design (DGN) Versions 7 and 8.
To change the default
units of measure (or other defaults), you must change the default
seed files specified in the MapExport.ini file.
Specifying the File and
Folder Selection Options to Use for Import
By default, when you
import ArcView Shape files, MapInfo MIF/MID,
MapInfo TAB, or VPF files, you can select one or more files in a
folder to import. This is called multi-select.
If you want, you can
change the settings in the mapimport.ini file so that these
formats are considered folder-based formats (you select a folder
and all the files in the folder are imported) or single-select formats
(only one file can be selected for import). Note that VPF can be
folder-based or multi-select only.
Importing DGN Cells
When you import data
from a DGN file, you can specify many of the DGN import options
available in Driver Options.
Importing Object Colors
as RGB (True Color) Colors
By default, objects are
imported using the ACI (AutoCAD Color Index)
color. When you import from DGN or MIF/MID, you can specify that
objects maintain their RGB color values.
Even if you import using
RGB colors, white objects are always imported to the ACI White,
which displays white on a black background and black on a white
background. Black objects are assigned the ByLayer color.
If you want to export objects to MIF/MID as black, change the layer
color to black before exporting.
Note that if your Model
Tab Background color is something other than Black or White and
you import using RGB colors, you may not be able to see objects whose
color is close to the background color.
Language Encoding Settings
for Importing and Exporting GML Data
When exporting GML data
in Asian languages, you must verify that mapexport.ini contains
the language encoding settings needed to export valid GML data for
the language you want.
Using Fixed schema mode
when exporting is recommended, as it can recognize certain multi-byte
characters that can be problematic in Create mode.
When importing GML data
in Asian languages, you must verify that the language encoding settings
specified in AutoCAD Map 3D’s mapimport.ini file match the settings
in your incoming file. The settings must match for the import to
Adding Custom Tags
If you are familiar with
the options for a driver, you can add custom tags. Use the format:
Where XXX is
the code you want to send to the driver. Add the line to the appropriate
section of the MapExport.ini file. Incorrect
tags will have unpredictable results.
Location of the .ini File
When exporting, AutoCAD Map 3D looks
first for the .ini file in the current directory.
If no .ini file is there, it uses the .ini file
in the C:\Documents and Settings\All Users\Application Data\Autodesk\AutoCAD Map 3D 2010\R17.2 folder.
To always use the same settings, do not create additional .ini files.
Changing Font, Line Style,
Line Weight, or Justification
You can set several formatting
options in the mapforeignfileproperties.ini file. Use
the [DGN_V7_FieldMappping] or [DGN_V8_FieldMapping] section to enable
a particular formatting option:
Use the [DGN_V7_Font]
section or [DGN_V8_Font] section to map DGN font numbers to textstyles
that you've defined.
Use the [DGN_V7_LineStyle]
or [DGN_V8_LineStyle] section to map DGN line styles to line styles
loaded in the AutoCAD Map 3D drawing.
Use the [DGN_V7_LineWeight]
or [DGN_V8_LineWeight] section to map DGN lineweights to allowable AutoCAD Map 3D lineweight
The DGN line weight range
is 0-31. AutoCAD Map 3D line weights are in 100ths of a millimeter and
only the following values are supported: 0, 5, 9, 13, 15, 18, 20,
25, 30, 35, 40, 50, 53, 60, 70, 80, 90, 100, 106, 120, 140, 158, 200,
211, -1, -2 and -3. The AutoCAD Map 3D values -1, -2, and -3 indicate ByLayer,
ByBlock, and by line weight default respectively.
Use the [DGN_V7_Justification]
or [DGN_V8_Justification] section to map the DGN justification to
AutoCAD vertical and horizontal modes or AutoCAD attachment.
DGN justification values
range from 0-14:
0 is Left/Top, 8 is Center/Bottom,
1 is Left/Center, 9 is Right Margin/Top,
2 is Left/Bottom, 10 is Right Margin/Center,
3 is Left Margin/Top, 11 is Right Margin/Bottom,
4 is Left Margin/Center, 12 is Right/Top,
5 is Center/Bottom, 13 is Right/Center, 6 is Center/Top, 14 is Right/Bottom,
7 is Center/Center, Default is 5
The following values
are supported for AutoCAD Map 3D justifications:
TopLeft, TopCenter, TopRight,
MiddleLeft, MiddleCenter, MiddleRight, BottomLeft, BottomCenter,
BottomRight, BaseLeft, BaseCenter, BaseRight, BaseAlign, BottomAlign,
MiddleAlign, TopAlign, BaseFit, BottomFit, MiddleFit, TopFit, BaseMid,
BottomMid, MiddleMid, TopMid
Use the [MIF_Justification]
section to set justification for MIF. Allowed MIF Justifications
are left, center, and right.
When importing from MIF
to AutoCAD Map 3D, the last mapping in the table is used.
Arc/INFO and E00 Justification
Use the [ARCINFO_Justification]
and [E00_Justification] sections to set justification for Arc/INFO
When importing from Arc/INFO
or E00 to AutoCAD Map 3D, the last mapping in the table is used.
