Definition

WAVE (What-if Alternative Value Engineering) creates linked geometry between two parts in an assembly. Source part publishes geometry (faces, edges, curves, datums); the linked part receives the geometry as a WAVE Link feature. Edits to the source propagate. Control Mode (Required, Optional, Frozen) controls how aggressively links update.

Why it matters

WAVE is the canonical top-down pattern in NX. For tightly coordinated mechanism design, mold design, and skin-and-stringer aerospace work, WAVE replaces ad-hoc inter-part references.

Common pitfalls

  • WAVE link sprawl — every part references every other part. Edits become unpredictable.
  • Frozen-mode WAVE links never updating — diverge from source.
  • Skipping publications — depending on source internal geometry that may change.

Relevant Siemens NX FAQs

Direct answers from our technical editorial desk concerning related workflows.

What is the equivalent of WAVE in other CAD systems?

Creo Copy Geometry, CATIA Contextual Design with publications, SOLIDWORKS in-context editing, Inventor adaptive parts. All address the same top-down-design problem with different mechanisms.

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.
