Define Parameters Wire Connector Cable
Pro/Cabling 3-D Harness Design
routed in assembly Logical Referencing
captures wire, spool and connector info defined in Pro/Diagram
Logical Data can also be imported from ASCII text files
Pro/Harness Manufacturing
Automatically flattens 3-D harness created in Pro/Cabling
Simulates harness layout on nailboard
Bends and twists can be added to optimize flat harness shape
Documentation Use flat harness in drawing
for manufacturing purposes Create customized wirelists
and BOM with Pro/Report Use 3-D harness for
assembly manuals and troubleshooting
Create and print drawing at full scale to use directly on the manufacturing nailboard
Terminology Component – An Electromechanical device that
sends/receives power and/or signals Connector – Connects wires/cables to
components or other wires/cables Node/Pin – Wire or cable attachment point to a
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 should
yield a useful footprint in mfg
Connectors should have at least 1 entry port (Csys). The Z-axis pointing out from body of connector.

Routing Without DiagramDefine Harness and Sub-HarnessDesignate and Define Connector
and Component ParametersDefine Wire, Cable and Bundle
Spools and ParametersDefine Wire, Cable and Bundle
NamesPhysical Routing
Define Harness and Sub-Harness
Based on chosen structure, create harness assemblies and assemble using default component placement
Create harness part within each harness assembly
Designate and Define Connector and Component Parameters
Specify component parametersSpecify entry port(s)Specify pins callout and signal name
Define Wire, Cable and Bundle Spools and Parameters
A spool is similar to a reel of wire or cable in which individual wires or cables are cut. It defines the parameters of the wires or cables (diameter, color, min. bend radius, etc.). Spools must be designated in a cable assembly before routing can begin.
A Sheath spool is used to specify sheathing for bundles. (Shrink, Tape, Tube Sheath, etc.)
Define Wire, Cable and Bundle Names
Create required wires, cables and bundles
Specify unique name for eachSelect appropriate spool for each
Physical Routing Options

Routing With a Diagram
Advantages of Logical References Allows wire list and connectivity info to
drive 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 (automatically
creates 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)
Pro/HARNESS MFG Techniques (cont.)
Flattening Process Set Start Point Choose Auto Fan Specify Bend Radius within range given Assemble all components Modify flattened model as desired (twist,
bend, break, reorient component, etc.)
Documentation Tables
Common Table Types Wire List Spool List BOM Connector / Pin Out Table
Create Pro/REPORT tables Define Table Add Repeat Regions (links system info to table) Enter Report Parameters Tweak the table
Save and Retrieve Finalized Tables for Future Use
Documentation (cont.)Views – Place Mfg Flattened Assembly
and 3-D Harness Model Views as needed
Advantages of Pro/E Provides an image of the physical routing and
the path of each wire and cable, preventing interference.
Able to determine accurate wire lengths without a prototype build, improving time to market.
Use 3-D models in assembly manuals Drawing can be created as full scale and used
directly on form board Logical Referencing saves time by eliminating
duplicate 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 between
Pro/CABLING and Pro/HARNESS MANUFACTURING
Changes in Pro/CABLING and Pro/HARNESS MANUFACTURING will be reflected in drawing
Associativity
