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 be successful.
Adding Custom Tags
If you are familiar with the options for a driver, you can add custom tags. Use
the format:
