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

Week 5&6 Wiring Harness Design Challenge-:

1. Introduction-: In this challenge we need to design & route wiring harnesses A&B as per the layout & check the bundle continuity, bundle warning, adding annotation sets & generate Cat.part & convert it in .igs file.

2. Wiring Harness B-:

Procedure-:

• First create a product assembly.
• Add the connectors & required components.
• Position the connectors as per layout.
• Then switch to Electrical Harness Assembly design workbench.
• Define the product assembly as a geometric bundle.
• Then create a multi brancheable part file in it.
• Define the routing between connectors as per layout using branch points.
• Now check the bundle continuity.
• For checking click on Edit<Search<Advanced<Electrical<Bundle<Segment<Fully Connected<True/False.
• Then click on search button for the results.
• If choosen true and it highlights all the branch that means your assembly is fuly connected.
• Now check the geometric bundle warning.
• If warning shown it will be mostly of bend radius.
• We can resolve that by defining stack in branches, changing tangent, changing bend radius, or by repositioning of connectors.
• Now to define annotations exit the multi-brancheable part file and switch to geomtric bundle.
• Switch to Assembly then choose the annotation style and define the each connector as per the desired properties to be highlighted.
• Now, to create geometric .Cat part from product assembly , open tools while in assembly workbench.
• Choose generate.Catpart option and define the part name click on, .Cat part will be generated.
• Save it & then change it to.igs format and save it again.

3. Wiring Harness A-:

Procedure-:

• First create a product assembly.
• Add the connectors & required components.
• Position the connectors as per layout.
• Then switch to Electrical Harness Assembly design workbench.
• Define the product assembly as a geometric bundle.
• Then create a multi brancheable part file in it.
• Define the routing between connectors as per layout using branch points.
• Now check the bundle continuity.
• For checking click on Edit<Search<Advanced<Electrical<Bundle<Segment<Fully Connected<True/False.

• Now to define annotations exit the multi-brancheable part file and switch to geomtric bundle.
• Switch to Assembly then choose the annotation style and define the each connector as per the desired properties to be highlighted.
• Now, to create geometric .Cat part from product assembly , open tools while in assembly workbench.
• Choose generate.Catpart option and define the part name click on, .Cat part will be generated.
• Save it & then change it to.igs format and save it again.

4. Final Assembly-:

Procedure-:

• Now Create a new product assembly.
• Copy the Harness Assembly A&B in the new product assembly.
• Position the assembly in desired orientation.
• Now switch to electrical assembly.
• Using the Connect Electrical devices tool, connect the required connectors in correct orientations.
• The constratints will get defined.
• Now save the assembly.
