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

AIM

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

OBJECTIVE

To flatten the wire harness assembly completed in week 4 assignment..

To place the flattened view on a drawing sheet.

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

PROCEDURES

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.

In below image show tools in flattern commands and these function shown below.

1.Flatteren Parameters

2.Extract

3.Flattern

While defining the harness flattening parameters,first in the general menu, to check Name, Active plan, and minimum angle between two branches and in the drawing menu double line is selected for bundle segment and protective coverings in order to 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'.
• 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.

This is the flattened the harness in proper orientation.

DRAFTING:

• Create a new drawing file and save the file in the same location.
• Insert the title block template and fill up the required details.
• dd 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.
• 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, connectors and the protection coverings.
• Show and name all the parts used in the wire harness assembly in form of a table.

CONCLUSION:

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