You can work with the Geometry API in several different ways:
Autodesk Geometry Format (AGF) is Autodesk's extended version of the Well Known Binary Format (WKB).
WKB is a memory layout used to store geometry used by GIS applications. This format was created by the OpenGIS organization to allow the efficient exchange of geometry data between different components in a GIS system. Most pieces of the original specification defining the WKB format are in the document, 99-050.pdf, the OpenGIS Simple feature specification for OLE/COM that can be found at www.opengis.org.
