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

INTENT:

To flatten the wire harness assembly completed in the week 4 assignment and place the flattened view on a drawing sheet.

OBJECTIVE:

• To flatten the wire harness assembly completed in the week 4 assignment.
• To orient the wire bundle as shown in the layout.
• Place the flattened view on a drawing sheet.
• To ensure bundles with protective coverings has different visuals on the drawing view

GIVEN:

SOLUTION METHODOLOGY:

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 line is selected for the bundle segment and a double line is 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 the '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.

Step - 4:

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

HARNESS ASSEMBLY:

HARNESS FLATTENING:

• We go to the harness flattening workbench and define the flattening parameters
• We use the extract command to bring the harness assembly to the flattening workbench here
• Choosing a suitable plane we flatten the harness assembly
• Bundle segments are rotated at the required angles the harness assembly is the drafted
• Flattening parameters are defined in order to make the bundle and the corrugated tubes visible in the 3d drawings.

Step - 5:

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

FOR DRAFTING REPRESENTATION:

Step - 1:

• Create a 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 flat faces of the connector and orienting the view as per the requirement.

Step - 4:

• Go to the properties of the view and select the '3D Wireframe' and ' Is always visible' options in order to see properly the Wire bundle, connectors, and protective coverings.

Step - 5:

• Show and name all the parts used in the wire harness assembly in the form of a table.

CONCLUSION:

• From the above assignment, we learned how to flatten a given wire harness assembly and how to place the flattened view on a drawing sheet and show all its components.
