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

Aim- To create a flatten view of previously created harness assembly.

Objective- The objective of this project is to create a flattened-view for a harness and then place it on the drawing sheet.It is desired that the bundles with protective coverings are represented with different visuals on the drawing sheet.

Above figure shows that the routed wiring harness according to given data specified on the diagram which is on the right side of it.

Step 1-Defining harness flattening parameters.

Above figure shows that the product file which we created seperately for flattening.After creating the product file we have to rename the product file as flattening product.

We have to keep that in mind that the type of representation for the bundle segment and protective covering should be different from each other.Also for devices ,"3D PROJECTION" can be used if the connectors are added to the electrical drawing catalog.

Step 2- Bring the harness assembly into the newly created flattening product by using the "Extract" feature.

It should be noted that our geometrical bundle assembly file is now changed to an "EHF" file which stands for "Electrical Harness Flattening".

Step 3-Flattening of the harness.

In order to flatten the harness we should select the plane or face of any connector and then select all the branches present in the harness assembly as shown below-

Above figure shows the flattening view of the wiring harness along the selected face that is along YZ-plane.

Step 4-Rotate the bundle segments.

Above figures shows that the branches are rotated along YZ-plane.

Step 5-Streamline the flattened harness.

For better representation ,we can use some other features like Bend,Roll to streamline the harness.At this stage,fake scaling can be done for few bundle segments if needed.For the current given wiring harness both "BLEND" AND "ROLL" features are used to bend and orient the bundle segments in the desired position.

Step 6-Making flattening-view drawing.

As per the objective of this project,we should make sure that the bundle segments and protective covering are represented differently.

"SINGLE LINE-Bundle segment.

"DOUBLE LINE-Protective covering.

Above figure shows the final drawing of the flatten-view of the wiring harness.

Final Flatten-view of the given wiring harness is shown below-
