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

AIM- To prepare a flattened-view of a previously created harness assembly

OBJECTIVE- The objective of this project is to create a flattened-view for a harness assembly and then place it on the drawing sheet. It is desired that the bundles with protective coverings are represented with different visuals on the drawing sheet.

Process -

1.) Define the Connector

• 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 bundle segment and 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 '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.

  • 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:

    • Create a new drawing file and save the file in the same location.
    • Insert the title block template and fill up the required details.

a) Download Connector 3D Part from www.te.com

• DT06-4S

b) Create a Required Geomtrical parameters- Point, Axis Systems

c) Define Part as a connector

Switch from part workbench to Electrical Part workbench, Using the Define connector command to define the connector as a Electrical component

Define the Bundle Connection point and Connector connection Point

Follow the same process for define the all connectors

• DT06-6S

• DT06-2S

• DT06-08SA

2.Now create a New Sketch in part workbench for Reference purpose

3. Now create a Context Assembly

a)Exit all components in that By using Exit component command

b) Switch from Part assembly to Electical Harness Assembly workbench

c) Using the Geometrical Bundle command Convert the product as Geomtrical Bundle

d) Using the Multi Branchble component Command to create the Bundles .

Next Create a Drawing 1

Next Create a Drawing 2

Next Create a Drawing 3

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.
