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

AIM

• To flatten the wire harness assembly and place the flattened view on a drawing sheet.

OBJECTIVE

• 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.

HARNESS ASSEMBLY

FLATTENING HARNESS ASSEMBLY

• 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 line is selected for bundle segment and double line is selected for protective coverings in order to differentiate between the wire bundle and cot tubes in drafting.
• 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.
• 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'.
• Save the product file using 'Save management' option so that all the related product files and part files are stored in single directory.

DRAFTING THE FLATTENING HARNESS ASSEMBLY

• Create a new drawing file and save the file in the same location.
• Add the front view of the harness assembly by selecting any one of the flat faces of the connector and orient the view as per the requirement.
