Wiring harness design in CATIA V5 - 3D modeling Week 7 Challenge
Electrical Harness Flattening:
At starting i defined all the 3D connectors electrically
and created wiring Harness between connectors.

Then settled general electrical flattening parameters
and created product in electrical harness fattening workbench,
using extract command extracted electrical harness rounting into
Electrical harness flattening workbench.
Added protection covering on elctrical routing.
Using flatten command, flattened the elctrical rounting to screen.
Adjusted routing using rotate, bend, role commands.
Then created new drawing sheet of A0 size and added flattening view
using create view command.
And showed harness routing with single line and protection covering with double line.
