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 flatten the wiring harness and the draft the wiring harness assembly.

. To place the flattened view on a drawing sheet.
. To ensure bundles with protective coverings has diffrent visuals on drawing view.
Harness assembly:
Step - 1:
. Create a product file and nevigate to the Electrical Harness Flattening for wire harness
flattening option and save it in the same location where the wire harness or routeing
assembly is stored.
. Define 'Harness flattening parameters' in order to flatten the required wire harness
assembly.
. While defining the harness flattening parameters in the drawing menu single line is
selected for bundle segment anf double line is selected for protective covering in order to
differentiate between the wire bundle and cot tubes in drafting.


Step 2:
. Selected the 'Extact' option from the Electrical Harness flattening workbench and select the
Geometric bundle product in the wire harness assembly product file.
. The wire harness assembly is imported to the Wire flattening product file with 'EHF'
extension added to the geometrical bundle assembly name.
Step -3:
. Select the 'Fletten' option to flatten the wire harness assembly.
. Then select the active plane, then select any one branch and then select the 'select all branches'.
. If there is no discontinuity in the bundle segment then all the branches will be selected and
by pressing 'ok' the wire harness assembly will be flattened.
Step-4:
Use 'Rotate' and other commands to rotate the branches and bring them in proper orientation
as per the given layout.
Step-5:
Save the product file using 'Save management' option so that all the related product files and
part files are stored in single directory.
For Drafting:
Step-1:
Create an new drawing file and save the file in the same location.
Step-2:
Insert the title block template and fill up the required details.
Step-3:
Add the front view of the harness assembly by selecting any one of the flate faces of the
connector and orient the view as per the requirement.
Step -4:
Go to the properties of the view and select the '3D Wireframe' on and ' is always visible option
in order to see properly the Wire bundle connector and the protection coverings
Step-5:
Show and name all the parts used in the wire harness assembly in the form of a table.
