NX was formerly known as "Unigraphics. NX is an advanced high-end CAD/CAM/CAE, which has been owned since 2007 by Siemens PLM Software. It is used, among other tasks, for:
● Design (parametric and direct solid/surface modeling)
● Engineering analysis (static; dynamic; electromagnetic; thermal, using the finite element method; and fluid, using the finite volume method).
● Manufacturing finished design by using included machining modules.
NX is a direct competitor to CATIA, Creo, Autodesk Inventor, and SolidWorks.
