Wiring harness design in CATIA V5 - 3D modeling Week 5 & 6 Challenge

Aim :

Route the Wiring harness layout in Electrical Workbench with given connectors according to the given instructions from the image below

• After routing, Check the bundle continuity.
• Add annotations to all the connectors with given numbering.
• If bundle warnings arise, resolve them as per instructions.
• Generate CAT.part of harness assembly and convert it to igs format.

Methodology

Procedure:

• First Download and import all the connectors from Harness A and Harness B in Catia.
• Define them geometrically and electrically as connectors and define bundle connection point, connector connection point

• Now import all the connectors of harness A and harness B in two seperate product files and arrange them as per instructions with help of snap, smart move and manipulation
• Open Electrical Harness Assembly and define them as geometrical bundles, Next by using Multi-branchable create bundle segments as per instructions

• Copy both the product files of Harness A and Harness B . After that create new product file, in that paste both of these under the product
• Arrange both of them in such way that they dont clash with each other by using manipulation
• Then open Electrical Harness Assembly and by using Connect electrical devices command, connect connector 5 and 6 and click update.
• If there are any bundle segments errors, resolve them. But in this case there were no errors so proceed further.
• After this step check for bundle segments connection- whether it is fully connected or not.

• From this we can see that all the bundle segments are fully connected
• Next step is to create annotations
• For this first we have to select a plane for annotations representations, so i have selected a face on the connecter as its plane of representation
• Next add flag note with ledger annotations to all the connectors with numbers

• Next step is to create a catpart from product file and save as igs file
• For this we have to select generate CAT part from product from tools in assembl workbench na dselect the product

• So after creating the CATpart, while saving click save as and select igs type in file format and save
• With this we have igs file of the assembly

Conclusion:

• Routing of the harness assembly of both Harness A and Harness B is completed.
• Connected both Harness A and Harness B in new product file with Connect electrical device command
• Checked for bundle segments errors and connectivity of bundle segments
• Added Annotations to all the connecters
• Created IGS file of the CATpart of the product file.
