Wiring harness design in CATIA V5 - 3D modeling Week 7 Challenge
The wiring harness is added into the harness flatening work bench and flattened. In order to represent the wiring harness for manufacturer we use 2d so in 2d we need flat patter to represent the details of the harness so we uses the flatening opetion as follows

And after flatening the details canbe drafted as the final output
Here I've used different representation for the bundle and the CoT tubes.
The zip file of the CAD part and drawing is attached with the challenge
