Nip-activity - Catia [updated] Jun 2026

Link the parameter nodes to functional actions using input and output pins. 4. Bridging Systems Engineering and Physical 3D CAD

Frequent Small Propagations: Instead of working for eight hours and saving once, propagate your changes every hour. This keeps the transaction logs manageable.

For large-scale deployments, developers use C++ (CAA V5) to create dedicated NIP executables. These programs load a CATIA document, apply a series of transformations (extrudes, fillets, lofts) via the geometric kernel (CGM), and save the result. This is how companies automate CAE mesh preparation or CAD translation.

On the 3DEXPERIENCE platform, NIP-Activity is often executed via or Exchange Server processes . A user can submit a "Batch NIP Request" from a web browser. The 3DEXPERIENCE server allocates a worker node (a CATIA engine without a screen), runs the NIP script, handles PLM revision rules, and notifies the user upon completion.

: This feature allows users to model and simulate various development processes, helping to identify potential bottlenecks and areas for improvement.

A macro can traverse an assembly, extract all part numbers, materials, and quantities, and write them to an Excel sheet via OLE automation—all without a user touching the mouse.

For advanced users, a "Deep Review" of a NIP-Activity might involve: 3DEXPERIENCE CATIA - Dassault Systèmes Link the parameter nodes to functional actions using

Typically involves moving from conceptual sketching to fully constrained 3D models . 2. Activity Reviews in PLM

Note: A full coding tutorial requires CAA licensing, but the logic flow is universal.

A furniture manufacturer has a base chair model with 10,000 potential variants (wood type, armrest style, cushion density). Interactive modeling is impossible. Using NIP-Activity coupled with Excel parameters, CATIA regenerates the 3D model for each variant in seconds. The process defines the specification, runs the NIP-Activity, and exports the STEP file. This keeps the transaction logs manageable

Writing a macro for NIP-Activity requires a different mindset than writing one for interactive use. You cannot rely on user input, screen selections, or standard pop-up messages.
