Wiring harness design in CATIA V5 - 3D modeling Week 7 Challenge
Objective:
- Flatten the harness assembly completed in the “ week 4 challenge”.
- Place the flattened view on the drawing sheet.
- Ensure bundles with protective coverings has different visuals on the drawing view.
Process:
Defining the cad files:
- Open the igs files and create a midpoint on the face using point type as between.
- Now we can create an axis system to the point we have created by using the command axis system
- definition.
- Make sure the x-axis is pointing towards the locking mechanism of the clip and the y-axis is pointing
- towards the face of the connector.
- We can create a midpoint on the entry using point type as between.
- Now we can switch to electric part design.
- Select the command bundle connection point.
- Enter the number of terminals required.




Harness assembly:
- Now we can open the electrical harness design workbench.
- Select the parent part and copy, and paste all the connectors we have defined.
- Now using line command in the assembly design.
- We assign the lines in the required dimensions.
- After creating the lines we can use the snap command to snap the connectors on the lines.
- Now we can select branch definition.
- We can select the branch and enter the dimensions.
- Now click on the protective covering command and set the end extremity value as 30mm.


Flattening:
- Open electrical harness flattening workbench.
- Select the flattening parameters command.
- Fill in the required parameters and click ok.
- Select the tile vertically command.
- Now Click on the extract option.
- click on flatten option.
- Select any face of the harness assembly and select all electrical bundles.




Drawing:
- Open a new drawing file.
- Click on the front view option.
- Now open the flatten assembly and select the face we have selected for flattening.
- Right-click on the red box around the drawing.
- Now enable the 3D wireframe option and is always visible option.
- Select the text option and name all the parts.
- To insert the Bill of materials, click on insert- Generate- Bill of material.
- We can also save the drawing in pdf format.

Result:
We have created the flattened view and flattened drawing of the harness assembly.
