Q1. Flatten the harness assembly completed in “ week 4 challenge”. Place the flattened view on drawing sheet. Ensure bundles with protective coverings has different visuals on drawing view.

Answer:

1.DT06-2S

Create midpoint on the contact face which will be normal to wire bunddle insertion.

Craete Axis System with respect to the point which we have created and defining the axis direction.

Switch to 'Electric Part Design'

Define the part as connector in catia, give no. of termination as 2 because we have 2 entry points for wire.

Bundle connection point:

Connector connection point:

2. DT06-4S

Create midpoint on the contact face which will be normal to wire bunddle insertion.

Craete Axis System with respect to the point which we have created and defining the axis direction.

Switch to 'Electric Part Design'

Define the part as connector in catia, give no. of termination as 4 because we have 4 entry points for wire.
Define Bundle connection point

Define connector connection point

3.DT06-6S

Create midpoint on the contact face which will be normal to wire bunddle insertion.
Craete Axis System with respect to the point which we have created and defining the axis direction .

Switch to 'Electric Part Design'

Define the part as connector in catia, give no. of termination as 6 because we have 6 entry points for wire.
Define Bundle connection point:

Define connector connection point

4.DT06-08SA

Create midpoint on the contact face which will be normal to wire bunddle insertion.
Craete Axis System with respect to the point which we have created and defining the axis direction as shown below.

Switch to 'Electric Part Design'

Define the part as connector in catia, give no. of termination as 8 because we have 8 entry points for wire.

Define Bundle connection point:

Define connector connection point:

Product

Open a new product file and imported all the defined models into it.
Draw a sketch as required.
Using snap arranging the Connectors by following the Layout.

Creating Multi-Branching to the connectors

creating a protective covering

Harness Flattening Procedure:

Harness flattening can be created from the Electrical Harness Flattening Workbench in CATIA V5.
Create a new product file in the Electrical Harness Flattening workbench and rename it as of our requirement.
Select the product file and define Flattening parameters to it. And we can rename it as of our requirement.
Save the flattening product file in the save folder which is having all the other required documents.
Create vertical windows with Harness assembly product and flattening product files.
Using the Extract option, extract the harness assembly into the flattening product.
Convert the extracted harness assembly into the flattened harness assembly by using the Flatten commend.

Create a Drawing File for the flattened harness product.

First, we need to make sure that in the flatten parameter settings bundles and protective coverings have different graphical representation which are,

Bundle Segments – Single line representation

Protective coverings – Double line representation.
