Use flat harness indrawing for manufacturingpurposes
Create customized
wirelists and BOM withPro/Report
Use 3-D harness forassembly manuals and
troubleshooting Create and print drawing

Terminology
Component
An Electromechanical devicethat sends/receives power and/or signals
Connector Connects wires/cables tocomponents or other wires/cables
Node/Pin
Wire or cable attachment point toa connector
Spool similar to a reel of wire, cable, etc.
Wire
A single sheathed conductor Cable Two or more conductors contained in
the same Jacket
Bundle Group of cables, wires or other
bundles that are sheathed together

Before Routing
Level of Detail
Connectors shouldyield a useful
footprint in mfg
Connectors shouldhave at least 1 entryport (Csys). The Z-
axis pointing outfrom body ofconnector.

Define Wire, Cable and BundleSpools and Parameters
A spool is similar to a reel of wire or cable inwhich individual wires or cables are cut. Itdefines the parameters of the wires or cables
(diameter, color, min. bend radius, etc.).Spools must be designated in a cableassembly before routing can begin.
A Sheath spool is used to specify sheathingfor bundles. (Shrink, Tape, Tube Sheath, etc.)

Routing With a Diagram
Advantages of Logical References
Allows wire list and connectivity info todrive harness (route to the correct places)
Easily track progress

Pro/HARNESS
MANUFACTURING Techniques Allows us to create a flattened (2-D) version
of the harness in preparation for
manufacturing document Creating the Harness Manufacturing Model
Create Manufacturing Harness (automaticallycreates mr_name.mfg and mr_name.asm files)
Select the design harness to flatten
Select simplified rep., if desired
Enter flat harness name (creates fr_name.asm)

Specify Bend Radius within range given
Assemble all componentsModify flattened model as desired (twist,
bend, break, reorient component, etc.)

Advantages of Pro/E
Provides an image of the physical routing andthe path of each wire and cable, preventinginterference.
Able to determine accurate wire lengthswithout a prototype build, improving time tomarket.
Use 3-D models in assembly manuals
Drawing can be created as full scale andused directly on form board
Logical Referencing saves time by eliminatingduplicate data entry

Model Associativity
Parametric Behavior Geometry, location and references can be
changed without losing model definition
Associative Behavior Two-directional associativity between
Pro/DIAGRAM and Pro/CABLING
One-directional associativity betweenPro/CABLING and Pro/HARNESS
MANUFACTURING Changes in Pro/CABLING and Pro/HARNESS
MANUFACTURING will be reflected in drawing
