CAT.KBL KBL - Electrical Harness Interface for CATIA V5

Version 4.7.6.1 | 12.03.2026

 Videos | Test license [30 days]  | Purchase

CAT.KBL is an interface between electrical and mechanical harness design solutions. CAT.KBL synchronizes the CAD wire harness with the ECAD electrical schematic. Supported CAD solutions are CATIA V5, 3DExperience and NX. Preferred ECAD systems are ENGINERING BASE by Aucotec, ARCADIA by CADONIX and PREEvision by Vector.

The The wiring diagram from the ECAD system can be imported and compared with the harness designed in CAD. Both CAD and ECAD KBL information are displayed in diagrams, enhanced by color-coded visualizations for better clarity. This enables the mechanical designer to identify, filter out discrepancies, and eliminate gaps effectively. Connectors, splices, protections, or supports can be automatically assembled or replaced based on the KBL information from ECAD if needed.
When the electrical design is completed in CAD, the electrical topology can be exported in KBL format. Using this information, ECAD systems can generate wire routing and 2D layouts for documentation purposes. CAT.KBL is a bi-directional interface, facilitating easy design modifications. For instance, if bundle diameters or lengths are adjusted, or connectors, splices, or protective devices are added, modified, or deleted, these changes can be synchronized with a few clicks to ensure identical data models in CAD and documentation.
