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

Aim: To create a flattened view of the previously prepared Electrical harness assembly in Catia V5.

Objective:

• Flatten the harness assembly prepared in the week 4 challenge.
• Place the flattened view on the drawing sheet.
• To add the protective covering and ensure that it is of different colour in the drawing

Procedure:

• Open the assembly model already created in Catia V5.
• Now open the new product file and select Electrical harness flattening workbench
• Give flattening parameters first.
• Bring the harness to assemble in the flattening product file using the extract option.
• After the assembly is extracted the file type is changed to.EHF (which stands for electrical harness assembly flattening) is shown in the below image.
• (Now we have to flatten the assembly) Select flatten option.
• Then select all the electrical bundles which have to be flattened as shown below.
• One can also select one main bundle branch and then click Select all branches in the flatten window.
• Open a new drawing file and set the following parameters as shown in the figure.
• First, save the drawing file as Assembly_Flattening.
• Adjust both the windows side by side for better understanding.
• Click the front view option in the drawing file and then select any one to flatten surface of the assembly.
• Enable the 3D wireframe option.

Conclusion:
The Flattened view and the flattened drawing of the Electrical harness assembly are created. The bundle protections are shown in different visuals compared to the bundle branches.
