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

Q1. Flatten the harness assembly completed in “ week 4 challenge”. Place the flattened view on drawing sheet. Ensure bundles with protective coverings has different visuals on drawing view.

AIM:- To prepare the flattened view of a previously created harness assembly

OBJECTIVE:- This project's goal is to flatten a harness assembly's view and then insert it on the drawing sheet. On the drawing page, several images should be used to depict the bundles with protective coverings.

Figure 1: A previously routed harness assembly that requires the creation of a flattened view

The Electrical Harness Flattening workbench of CATIA V5 should be used to create a flattened view of any wiring harness. We must ensure that the flattening file is located in the same folder as the harness assembly's component elements.

CONTENT:-

The following steps are to be done to complete this project.

STEP:-1 Defining harness flatteing parameters

At the Electrical Harness Flattening workbench, we should first create a new product file. By clicking on its icon as displayed above, we should define the harness flattening setting next. We should select the parameters as indicated above in the general tab. We should define the parameters for the drawing tab as shown below once the general tab settings are finished.

It should be noted that the protective covering and bundle segment have different ways of representation. In the event that the connectors are included in the electrical drawing catalogue,"3D projection" can be used for devices as well.

STEP 2:- Rename the product file as flattening product.

STEP 3:- Bring the harness assembly into the newly created flattening product by using the "Extract" feature.

The flattening product and harness bundle tabs should be vertically aligned first. Now, as illustrated below, we should incorporate the harness assembly into the flattening product using the "EXTRACT" feature of the electrical harness flattening workbench.

It should be noted that the "EHF" file, which stands for "Electrical Harness Flattening," has replaced our geometrical bundle assembly or harness assembly file.

STEP 4:- Flattening of the harness

As illustrated below, after selecting the flatten plane, we should choose each branch that is part of the harness assembly.

The raw flattened view of the wiring harness along the chosen XY-Flattening plane is shown in the figure above.

STEP 5:- Rotate the bundle segments

Using the "Rotate" option on the flattening workbench, all bundle segments should, if necessary, be rotated in the appropriate direction. It should be noted that since the "XY-plane" serves as the flattening plane, we must ensure that the bundle segment is only rotated on the "XY-plane" direction.

Here are the solution of above question and image of drawing view
