Consider the design of a ship's transverse bulkhead. Several horizontal and vertical stiffeners must intersect a thick outer plate perfectly to create a watertight seal. Using the Nibbling activity allows the designer to take the "StrPlates" and "StrMembers" and automatically cut them to fit the exact curvature of the hull or the intersecting beams, a process that would take hours of manual surface trimming if done using traditional methods.
Run the File > Desk > Right-click > CATDUA V5 utility regularly on your NIP components to eliminate ghost links and structural errors. : Use the Pad icon to extrude your 2D sketch into a 3D solid
CATIA’s Cache System works excellently with NIP. Set non-critical parts to NIP during initial loading. This loads their visual representation (CGR - Visualization mode) without loading their full geometric data. : For standard nuts, bolts, and small brackets in a master assembly, set them to NIP by default. Activate them only when detailed design work is required.
Set a dedicated local SSD path for the cgr (CATIA Graphical Representation) files. Using the Nibbling activity allows the designer to
Manually clear your local cache directory before activating a new NIP.
Apply NIP activities conservatively: automate data extraction, validation, and reporting while avoiding direct edits to production models. Use copies, APIs, robust logging, and PLM integration to keep processes safe, repeatable, and auditable.
The quality of your nibble is directly reliant on the quality of the inputs. Before you run the Nibbling tool, ensure your base parts and limiting surfaces are free of small gaps, duplicate geometry, or self-intersections. As a general rule for robust CATIA modeling, using simple, fully-constrained sketches as the foundation for geometry ensures ease of modification and reduces the risk of update failures later in the design cycle.
