You can import Vector
Product Format (VPF) files into AutoCAD Map 3D. You cannot
export to this format.
VPF is a standard format,
structure, and organization for large geographic databases that
are based on a georelational data model. It is commonly used by
military departments and defense agencies.
The VPF specification
is available on the National Imaging and Mapping Agency (NIMA)
By default, AutoCAD Map 3D considers Vector
Product Format (VPF) a multi-select, file-based format,
that is, you select one or more individual files during a single
import process. You can edit the mapimport.ini file
to specify that all files in the folder are included in the import
or that only one file can be selected for import.
data sets can be very large. You can use a spatial filter to limit
the size of the DWG you create from VPF data. See Specifying an Area to Import
VPF has no import driver
