NX is a solid modeling package based on the Parasolid kernel. The package contains many (mostly optional) modules, for example CAD, CAM, CAE, Sheet metal applications, knowledge bases, Quality control and Rapid prototyping. The file structure is binary.
The following table explains how common elements are called in both Alias and NX.

Supported NX geometry and data mapping
The following sections describe the mapping process used for geometry types and non-geometric data that can be transferred between Alias and NX.
Supported Alias geometry types
The following Alias geometry types can be exported to NX. Non-geometry entities such as Lights, Cameras, Textures, Windows, Animation are not supported by the translator. The numbers in the table entries refer to Notes for NX entities below.
