NX, formerly known as “UG”. In 2000 Unigraphics purchased SDRC I-DEAS and began an effort to integrate aspects of both software packages into a single product when became Unigraphics NX or usually just NX, is an advanced high-end CAD/CAM/CAE, since 2007 owned by siemens PLM software.
It is used, among other tasks, for:
- Design (parametric and direct solid/surface modeling)
- Engineering Analysis (static; dynamic; electro magnetic 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 Topsolid, Catid, Creo, Autodesk Inventor, and Solidworks.
