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

WIRING HARNESS FLATTENING IN WEEK 7

CHALLENGE

AIM:

To flatten the wire harness assembly completed in week 4 assignment and place the

flattened view on a drawing sheet. To orient the flatten view as shown in layout below.

To ensure bundles with protective coverings has different visuals on drawing view.

Design METHODOLOG'

Step -1

• Create a product file and navigate to the Electrical Harness Flattening for wire harness

flattening option and save it in the same location where the wire harness or routing

assembly is stored.

• Define the Harness flattening parameters in order to flatten the required wire harness

assembly, while defining the harness flattening parameters in the drawing menu single

selected for bundle segment and double selected for protective coverings in order to differentiate between the wire bundle and cot tubes in drafting.

Step - 2:

Select the ‘Extract’ option from the Electrical Harness flattening workbench and select the

Geometric bundle product in the wire harness assembly product file.

Then wire harness assembly is imported to the Wire flattening product file with ‘EHF

extension added to the geometric bundle assembly name.

Step-3:

• Select the ‘Flatten’ 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.
• Use ‘Rotate’ and other commands to rotate the branches and bring them in proper orientation as per the given layout.

Step-4:

• Save the product file using ‘Save management option so that all the related product files and part files are stored in single directory.

Step-5:

FOR DRAFTING:

• Create a new drawing file and save the file in the same location.
• Insert the title block template and fill in the required details.
• ‘Add the front view of the harness assembly by selecting any one of the flat faces of the connector ‘And orienting the view as per the requirement. Adding the title block
• Finally, bill of materials is added.

Conclusion: - From this challenge we have learn how to use the wiring harness flattening workbench. Make familiar with its user interference and its command. we have successfully done the challenge and complect the drawing.
