About
UFUNC (User Function) in NXOpen UFUNC (User Function) is a low-level programming interface in Siemens NX that allows developers to access and manipulate the underlying data structures of NX models. UFUNC predates NXOpen, and while NXOpen provides a more modern, object-oriented API, UFUNC is still used for certain advanced or legacy operations. Key Features: Low-level Access: UFUNC provides detailed access to NX's internal functionality, allowing developers to perform operations that may not be possible with higher-level APIs like NXOpen. Procedural Programming: Unlike NXOpen, which is object-oriented, UFUNC uses a procedural programming approach, closer to the C language. Flexibility: It supports a wide range of operations from geometry manipulation to data retrieval, making it useful for specific tasks in automation or customization. Backward Compatibility: UFUNC remains important for legacy code and projects that were built on earlier versions of NX. Use Cases: Automating repetitive tasks within NX. Customizing user workflows by creating new commands or modifying existing functionality. Accessing and modifying low-level geometric data. Legacy support for older NX implementations.
