SHP files do not support circular arcs. During export, arcs, splines, and ellipses
are converted to segmented polylines. You can change the settings used for
segmentation in the mapexport.ini file.
You cannot map fields when you export to Shape Multiclass. If you need to
map fields, export your DWG data to SDF first, and then use
Migrating Data
(page 615) Bulk Copy to export the data to SHP.
Overwriting and Appending
If you export to an existing folder containing files with the same names as
those that will be generated by the export, you can choose to overwrite the
existing data or append the new data to it. Overwriting can destroy the existing
files when it creates new ones. Appending adds the data in the current export
operation to the existing data without deleting any existing data. If you append
and you are transforming the coordinate system for the data, the old data and
the new data must both use the same source and target coordinate systems.
You cannot use the append option to update existing data, but only to add
new data.
NOTE If your data meets these criteria but the export operation fails, try deleting
the relevant .prj files in the target folder and then retry the export operation.
Driver Options
When exporting to SHP files, you can select 2 Dimension Shape Files or 3
Dimension Shape Files from the driver options.

NOTE When you export from a map, only drawing objects are exported. Geospatial
features are ignored. To move geospatial feature data to another format, use
Migrating GIS Data (Bulk Copy) (page 617).
