Nip Activity Catia Best Patched (2025)
What is NIP Activity in CATIA?
NIP stands for Neutral Input Point.
A NIP Activity refers to the process of inserting, positioning, and managing neutral (non-parametric) geometry—such as imported IGES, STEP, or STP files—within an active CATIA part or product. This is critical when working with legacy data, supplier models, or multi-CAD collaborations.
: For complex items, define user parameters at the top of the tree so that major dimensions can be changed without diving into individual sketches. 3. Data Integrity and Handover Since NIP is often a proposal for others to follow: Publish Key Elements nip activity catia best
- Do not nip three surfaces at the same vertex. Trim surfaces in sequence (Surface A, then B, then C).
- Use Conic Fillet instead of standard
BiTangent Filletfor the best curvature flow.

1. Low NIP Count = High Quality
Unlike polygon modeling, more points is not better in CATIA. A Class A surface for a car door might use only 6x6 NIPs. Start with the minimum number required to define the shape, then subdivide only if necessary.
