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

WIRINING HARNESS FLATTENING:

First Step create New Product File

• Open catia V5 and opened a new product file and already created wiring harness assembly routing.
• Rename the product file into a 'Flattening Product file'.

Setting the flattening parameters:

• Switch to the Electrical Harness Flattening.
• Select the command called Harness Flattening Parameters.
• In general tab, change the minimum angle distance between them to 15 to 20 degree.
• Enable, keep existing tangent between bundle segment and connector during the flattening step.
• Also enable, Extract only the supports inside the geometrical bundle.
• Select the Radius of the bundle segment for the Roll radius for Quick roll.
• Keep the parameters default or change according to our requirement.
• Save this file as a Flattening product in the path where the required wiring harness assembly file is located.

Extract Harness Assembly:

• Opened the wiring harness assembly file and tile the window vertically.
• Select the Flattening product file in model tree and select the extract command in Electrical Harness Flattening workbench and select the wiring harness assembly file to fetch the required information.
• Now the wiring harness assembly file details are extracted into the flattening product.
• Now select the Flatten command in Electrical Harness Flattening Workbench.
• Select the active plane as a required surface or any other required planes.
• Keep default parameters in Algorithm mode and Angle mode.
• Select the branches and select ok to perform the Flatten operation.
• Use the other commands such as rotate, roll, straighten and synchronization for the alignment of Flattening product.

Creating 2D Harness Flattening Drawing File.

• Open the new drawing file and save as a Harness Drawing File.
• Keep ISO as a standard and A0 ISO as a sheet style.
• And select Landscape.
• Now select the Front view command in Drawing file and select the required surface or the plane for view in the flattening product file.
• Now the flatten product details are delivered into the drawing file in a 2D.
• Now go to the properties and select the view tab, under dress up section, enable the 3D colors (if needed) and also enable the 3D wireframe is always visible.
• Now the full details of flatten product details are obtained in a 2D form.
• Now the connectors are represented in a 2D. So we can change the representation into 3D by changing the flattening parameters in the flattening product file.
