Introduction

The Geometry API supports specific Autodesk applications and APIs, including FDO (Feature Data Objects). This API consists of the following components:

a Geometry Type package (all through fully encapsulated interfaces)
an Abstract Geometry Factory
a Concrete Geometry Factory for FGF

You can work with the Geometry API in several different ways:
