NX¶
Siemens NX is a CAD/CAM/CAE software suite developed by Siemens PLM Software. It is used for design, engineering analysis, and manufacturing. Similar to CatiaV5, NX is a native format built for the Siemens NX software suite. It can store and contain all information relevant within NX workflows.
🔍 See 3D Data Concepts for details and definitions.
Extensions¶
.prt
Structure¶
NX files are binary files and can be monolithic or nested. A .prt-file can describe either a single part or an assembly. Both are supported by instant3Dhub.
Geometry¶
The geometry of a NX file can be described as a combination of B-Rep and Tesselation. The B-Rep is the underlying representation of the geometry, while the tesselation is used for visualization purposes. instant3Dhub supports both representations.
PMI & Model Views¶
PMIs and Modelviews contained in a NX file will be loaded and exposed by instant3Dhub.
Metadata¶
The metadata of a NX file can be described as a combination of attributes and properties. Attributes are used to store information about the geometry, while properties are used to store information about the part or assembly. instant3Dhub supports both representations.
Miscellaneous¶
As a native format, a multitude of different information of different concepts in the NX Modeler can be stored within the format.
Assembly Constraints¶
In Siemens NX, constraints (also called assembly constraints) are used to define relationships between components within an assembly, restricting their degrees of freedom and ensuring correct positioning. Typical constraints are: Touch/Align, Center, Distance, Angle, Fix, etc. While instant3Dhub does not read or expose constraints, the resulting transformation of parts within the assembly is reflected and loaded.
Layers¶
Similar to JT, layers are supported by instant3Dhub.
Reference Sets¶
Reference sets are a way to manage different representations of a part within an assembly. They allow users to create and switch between different views of the part within an assembly. A experimental implementation to support reference sets is available in instant3Dhub on request. ..
