select the Polygon object type and select Treat Closed Polylines As Polygons
on the Options tab.
All new SHP classes that contain text entities will have a property called
TEXTSTRING. To bring this information back into AutoCAD Map 3D,
select the import option to import points as text.
■ The
Shape Multiclass (page 1443) export option.
This is a separate option on the drop-down list in the Export dialog box
that exports multiple drawing objects to a set of SHP files in a folder you
specify. Each resulting SHP contains the geometry and attributes for a
single geometry type, and is stored in files that indicate that type, for
example, PARCELS_POLYGON.SHP.
You can specify that the resulting files use a single feature class or multiple
feature classes based on layer, object classification, object data, or link
templates.
You can also export object data or external database links to the corresponding
SHP database (DBF) file.
Export Restrictions
SHP files do not support color; in ArcView, each theme is assigned a color that
is used when an item is drawn.
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.
Overwriting or Appending
If you export to an existing file, or to a 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 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.
If you are using either the folder or the multi-file Shape option and you choose
to append, AutoCAD Map 3D checks the target folder for existing files that
