Definition

Synchronous Technology (ST) operates on solid geometry through face-level commands: Move Face, Pull Face, Resize Face, Make Coplanar, Make Perpendicular, Modify with Rules. It works on both native parametric geometry (where it adds a Synchronous feature step to the timeline) and imported direct geometry (where there's no parametric history to disturb).

ST infers design intent through rules (e.g., 'this face was perpendicular to that face — preserve that') and applies the edit while respecting inferred constraints.

Why it matters

ST is NX's competitive moat. Mixing parametric and direct in one platform without losing data is uniquely NX. For imported geometry, ST is the only practical way to make significant edits.

Common pitfalls

  • Heavy ST use on parts with long parametric history — history becomes misleading.
  • Relying on rule inference for edits that should be explicit dimensional changes.
  • Mixing ST and pure parametric features without a discipline for which is which.

Relevant Siemens NX FAQs

Direct answers from our technical editorial desk concerning related workflows.

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.

What is the difference between NX and Solid Edge?

Both Siemens products. NX is high-end, used by automotive OEMs and tier-1s, with Teamcenter PLM. Solid Edge is mid-market, similar tier to SOLIDWORKS, mainstream machinery and consumer products. Both share Synchronous Technology heritage.

Can NX open SOLIDWORKS files?

Yes — NX has direct read for SOLIDWORKS, CATIA, Creo, and Inventor native files via the Multi-CAD Translator. The imported geometry can be used in NX assemblies and modified via Synchronous Technology.
