Exporting to ArcView Shape Files
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 type (point/line/polyline/text).
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 5 degrees.
You can change SegmentationDegrees and FME_ARC_DEGREES_PER_EDGE
to be larger or smaller.
Exporting to MicroStation DGN Files
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 (page 405).
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.
