Overview: NIP activity in CATIA refers to non-intrusive processes and practices for integrating, monitoring, or automating tasks within CATIA environments while minimizing disruption to existing models, assemblies, and workflows. Following best practices ensures model integrity, repeatability, performance, and collaboration.
This is the most critical action.
To use NIP geometry in a CATPart:
Before diving into the "how," let's define the acronym. NIP stands for NURBS Intersection Point. NURBS (Non-Uniform Rational B-Splines) are the mathematical foundation of CATIA surfaces. An Intersection Point is where a curve or surface boundary interacts with the internal knot vectors of a NURBS patch. nip activity catia best
NIP Activity refers to the dynamic visualization and analysis of how these internal control points align or misalign across adjacent surfaces. When you activate NIP display, CATIA shows you the internal "tessellation" or the "skeleton" of the surface—specifically, the isoparametric curves at the knot locations.

The best designers use NIP activity as a reflection simulator. The NIP grid acts as a stand-in for light reflection lines (Highlight lines). To use NIP geometry in a CATPart: Before
Here is the definitive workflow to maximize your nip quality in CATIA V5 or V6 (3DEXPERIENCE).
