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.
