Wiring harness design in CATIA V5 - 3D modeling Week 7 Challenge

Downloading all the components required for the challenge. Namely,

• DT06-4S

• DT06-6S

• DT06-2S

• DT06-08SA

STEPS FOR HARNESS ROUTING.

1. Next step is defining all the connectors and Bundles in Electrical Part Design [EPD] using points and Axis for connector.
2. Generate branches according to the dimensions given in the question and save it as CATPart.
3. Import Branch file into the product file in Electrical Assembly Design [EAD].
4. Use Snap option from Move Toolbar available in the Assembly Design Workbench [general] to align the components according to the question.
5. Use compass to define the orientation of the components according to the diagram given in the question.

Alignment in Assembly Design Workbench.

6.Create Multibranch Routing in Electrical Harness Installation with protective coverings. Here I made use of 15mm COT TUBE [available in the catalog] since the wire diameter for routing is 10mm.

30mm gap is given for every COT Tube covering in both start and end points.

Harness Assembly was flattened using Electrical Harness Flattening [EHF] Workbench.

Electrically component is defined in Electrical Part Workbench [EPW] and harness is generated using Electrical Harness Assembly and Electrical Harness Installation Workbenches and final component is shown below with its tree structure.

Harness parameters are set before proceeding to the EHF Workbench.

The Assembly Harness is extracted in the Flattening workbench using Extract option and flattened using Flatten tool as shown below. The file is saved with extension .ehf file

Drawing Workbench is used to generate 2D drawings and it is opened using Files option available in main toolbar. The 2D drawing is generated using front view option and annotated is added using Text Tool with Title and Frame box and Bill of Materials [BOM] as shown below.
