PrefaceThe CATIA Version 5 Electrical Harness is a new generation product which is dedicated to thedesign of physical harnesses within the context of the 3D mock- up.Users benefit from electrical designs totally integrated into the mechanical assembly.This product provides a set of objects including both mechanical and electrical properties.

The CATIA - Electrical Harness product offers the following main functions:the bundle segment creation in Product documents (Electrical Harness Assemblyworkbench) the geometrical bundle creationthe bundle segments properties definitionan algorithm simulating the bundle segment shape and offering realistic bundle segmentrepresentations.

Thanks to the integration with mechanical assemblies, electrical harnesses can be connectedeither to mechanical parts, or to electrical devices.CATIA - Electrical Harness Installation enables users to reuse catalogs of electrical devices.

As a scalable product, CATIA Version 5 Electrical Harness Installation can be used incooperation with other current or future companion products of the next CATIA generation suchas CATIA - Electrical Wire Routing and CATIA - Electrical System Functional Definition.

bend radius The bend radius is the minimum bend radius allowed for the bundle segment.bundle A document containing wiresbundle segment Also called segment, a geometrical subdivision of a bundle.

It is the wire graphical representation in the digital mock-up. The bundle segment iscreated according to several rules:

the bend radius must be superior to half the diameterin slack mode, an extra-length is added to the bundle segment calculatedfrom a bend length percentage (Slack%).the bend mode calculates the minimum length through all the constraintpoints, with regard to the minimum bend radius.the length mode uses the length value: this value must be at least equal tothe distance between the points.

functional connector (from EFD application) and physical connector (from V4,Electrical Library and Catalog)
