All attributes you specify here are included in all the resulting features
you export to ESRI ArcSDE. For information on how the choices on this
tab determine the properties of the exported feature class, see Exporting
to Multiple Classes
(page 1439).
8 On the
Options tab (page 1704), specify whether to convert the coordinate
system during the export process and choose the coordinate system.
Specify whether to treat closed polylines as polygons when you export.
9 Click Save.
Exporting to ESRI SHP
AutoCAD Map 3D supports up to ArcView version 3.2 and 8.x.
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).
About SHP Files
ESRI SHP files store both geometry and attributes (data) for features. A single
shape can have as many as five physical files with the same filename, but
different file extensions:
■ .shp— Geometric data. Data for multiple points, polylines, and polygons
can be stored in one SHP file, but each SHP file can store only one type of
geometry. For example, a line SHP file can contain data for rivers, roads,
and pipes.
■ .shx — A geometric index to the map features, which can be used by some
applications to find features in disparate sections of a large map.
■ .dbf— Attribute data associated with the map features.
■ .prj—Projection and coordinate system data. This file is created only if your
map has an assigned coordinate system.
■ .idx—Identifies the index field for the related SHP file, which is the unique
identifier for each entity in the SHP file.
