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

As per the image below, the wiring harness assembly is created according to the layout mentioned above with all the connectors electrically defined and corrugated tubes added to necessary bundles.

After that, the CAT product file of the harness assembly is extracted to the flattening workbench where all the flattening properties are defined and once the CAT product is extracted the file is saved.EHF(Electrical Harness Flattening Assembly) file and now the flattening file is saved in the location where the wiring harness assembly is saved. Now the harness assembly is flattened using the Flatten command as per the image shown below.

Once the flattened product is obtained make all the necessary changes like scaling, rolling, rotating, straightening etc. Now transfer the flattened assembly onto the 2D drawing sheet by creating a new drawing sheet and save the drawing sheet in the same location as all the files saved before.

Now select the front view option and select the plane of the flattened which was selected earlier in the flattening properties.

Now the 2D diagram of the flattened model is displayed on the drawing sheet, now to go the drawing properties and in the view section make sure the 3D wire frame is always visible which represents the bundles and make sure the graphic for a device is a 3D projection for better identification and understanding and single line for bundle and double line for protective coverings, and 3D colours can be added for a better look as per the image shown below.
