Definition

NX parts contain features in the Part Navigator. Each feature can be edited (Edit Feature), suppressed, or rolled back. Features can be grouped under Feature Groups for organisation. Parameter expressions can drive multiple feature dimensions.

Why it matters

Parametric features are the design intent. Well-named, well-organised features make a part maintainable; chaotic features make it disposable.

Common pitfalls

  • All features at one level without grouping — Part Navigator is overwhelming.
  • Default-named features ('Extrude(2)') instead of intent-named.
  • Suppressing features as a quick fix accumulating technical debt.

Relevant Siemens NX FAQs

Direct answers from our technical editorial desk concerning related workflows.

What is the difference between NX and UG?

Same product, different name. UG (UniGraphics) is the legacy name from 1973 until 2002, when Siemens (then EDS) rebranded to NX. Veteran users still say 'UG.' The .prt file format is continuous across the rename — UG files can open in modern NX.

What is Synchronous Technology and why does NX have it?

ST is direct-face editing on a body without disturbing parametric history. NX has it because it solves two pain points: editing imported geometry without history, and editing native parts when parametric edits would be tedious. Mixing ST with parametric is uniquely NX's capability.

Does NX require Teamcenter?

Not technically — NX can run with the native filesystem. But production deployments almost always use Teamcenter (or NX X with Teamcenter X for cloud). Without it, large-assembly performance and revision control become unmanageable.
