Routing: Biggest Potential for efficiency increase !
How to create routing paths efficiently ?
14. CREO CABLING
Manual Routing
• User creates the wires one by one
• Mainly for visualisations , manuals , manufacturing
information
• For small amount of wires
• User has fully control on the wire path
15. CREO CABLING
Auto routing
• User defines the possible paths for
wires as a 3d wire-frame object
• This ‘virtual channel’ also defines the
topology of the harness
• User creates connections from device
to device as ‘air-lines’
• Cabling automatically puts all ‘air-
lines’ into the ‘virtual channel’ by
finding the shortest path between
two points
• Mainly for large amount of wires
• Necessary for harness topology
16. CREO CABLING
E-CAD routing
• User defines the possible paths for
wires as a 3D wire-frame object
• This ‘virtuel channel’ also defines
the topology of the harness
• Cabling creates connections from
device to device as ‘air-lines’
automatically from the E-CAD
interface file
• Cabling automatically puts all ‘air-
lines’ into the ‘virtual channel’
• Necessary for harness topology
• Eliminates user errors
17. CREO CABLING
Electrical Library (CCF Format)
• Some components
already available in
“Cabling”, others can be
easily added into the
systems
• Powerful librarian for
fixture and pin definitions
• LISP driven fixture
elements like Clamps etc
18. CREO CABLING
Auto-Snap Functionality
Users can interactively
define components and their
counterparts
by defining mate faces on
both components and
counterparts.
Once selected, components
automatically “snap” to their
counterparts without user
interaction.

Cabling Manufacturing
• Create an accurate 2D representation of the 3D
harness.
• Add standard or “embedded” dimensions to
actual wire and bundle lengths.
• Annotate the drawing with pin, wire and
connector properties.
• Add other data needed for manufacturing like
wire run lists, bill of materials, connector
information etc.
• Move and rearrange the complete harness, each
cable segment independently.
• Create different reports about the manufacturing
process.
• Various design rule checks eliminate errors and
ensure that pre-defined rules are obeyed.
• One-to-one or scaled manufacturing drawing.
• Possibility to customize the manufacturing
drawing depending on the company standards.
• Export of length information back to the E-CAD
system.

Creo Cabling E-CAD Connection
• Cabling can read and write data
from/to any E-CAD system,
which is capable of preparing
wire-lists in a special ASCII
format.
• After cable and connector data is
read, devices are checked for
existence and an air-net cabling
connection is built automatically
from pin to pin.
With Cabling functionality users
can modify air-nets to 3D
Harnesses.
Wire List of an E-CAD System
...is converted into the Cabling E-CAD
Input format
33. CREO CABLING
Creo Cabling E-CAD Connection
• Cabling checks Creo model
space automatically and finds
out which devices are already
placed – and which ones user
must still load to the model
• By simply selecting from the
“Not Placed” list, users can
load and position connectors
within one menu.
34. CREO CABLING
Creo Cabling E-CAD Connection
• Loaded pkg-parts get
automatically new names
assigned
“Connector_Device

Detect problems at early stage: For example fiber cables has a problem with bend radius. The cable cable can not be bended to much as permitted. Bend radius: the minimum radius that a fiber optic cable can be bent without loss of light or impairment. The radius varies with different cable designs but follows a general rule that it can not be less than 15 times the cable diameter.The minimum bending radius will vary with different cable designs. The manufacturer should specify the minimum radius to which the cable may safely be bent during installation, and for the long term.
Cabling has 4 main functionalities- Cabling Design - E-CAD Interface- Electical Library- Cabling Manufacturing
Dynamic Cabling: Cables and wires are modified full dynamically similar to the Direct Modeling concept of Creo for any type of cables ...simply by dragging cable segments!
Routing Types- Manual Routing- Automatic Routing- E-CAD Routing (Routing via E-CAD Interface)Manual RoutingUser is manually routing a wire/cable as if he is creating a 3D curve through the space. From face to face (bend radius)On a single face (planar, cylindrical) From face to ‘space’ In 3D ‘spaceetcAutomatic Routing (Channel routing)Auto-routing through predefined channels.The base of this type of routing is a predefined "virtual" cable channel net.User only selects the start and end point of the wire/cable close to the channel end points and Cabling finds automatically the shortest way between the points - routing the wire automatically inside the channel.(User must create the virtual cable channel (path) prior to starting automatic routing using the [Create Cable Path] menu)E-CAD RoutingAll necessary connections are defined in a text file - coming from an external Electrical CAD Software (E-CAD).Cabling reads this file as input and creates all wire routings automatically.
Manual Routing ... to route multiple cables easy as single cable ...Bring single cores automatically together … …even flat cables can be easily splitted and bundled together!Simply click points on a face to define the cable route ...Move core end point to any point ...... and re-split anytime to route single cores seperately…and can be “splitted” or “bundled” anytime during modelling+ easy to understand+ what "beginners" think of "cabling"+ realistic look of wires+ good for small scale cabling processes (< 15-20 wires)+ more control of path (fillets, exactly on face ..)- every wire must be created one by one- limited/no drawings will be generated inside "Manufacturing" function(use reports generated)- modifications of existing wires are difficult - no connection to E-CAD
Automatic Routing + good for bigger scale cabling processes (> 15-20 wires)+ very easy when many wires are going parallel+ drawings will be generated inside "Manufacturing" function+ easier modification of existing wires via Un-Route/Re-Route+ connection to E-CAD+ automatic detection of "Splice" position+The shortest path between these pointson the channelis automaticallyfound and the objectis routed+Put several objects (wires,cables,bundles) into one channel of any complexity.Objects may havedifferent fillet radii.new approach - difficult to understand in the beginning in the demos- not realistic look - cables on top of eachother- rough path (no fillets)
CCF - Catalog Creation FileCCF is a simple macro-based ASCII file, which defines :- a hierarchical menu structure with unlimited sub-menus- menu pictures (in BMP format)- user definable menu sizes- 5 different operations(load PKG, run external program, call a "Creo E/D Modeling" dialog, call a LISP function, load from ModelManager, load from WorkManager )CCF Libraries ensure, that parts are stored in correct sub-assemblies and correct positioning-menus are pre-selected for the user.FeaturesCreation of user friendly menus Catalog creation with drag and drop Free definable fixed menus sizes Intelliplace functionalityCentral management of catalogs from serverOne secure vault for the whole Library partsThis vault could be only accesed from the authorised peopleDifferent action types for individual library fieldsSyntax checkerfor ensuring error free CCF'sDifferent levels of CCF’s are possible depending of the companys structure, for example “Designer Level”, “Department Level” or“Enterprise Level”CCF engine used in “Cabling" is the same library engine like used in SolidGenius“Cabling" comes with 3 pre-defined demo CCFs for :- Connectors- Terminals- Fixtures
Manufacturing functionalitygenerates 2D flat drawings from Cabling 3D harnesses (with the help of the Annotation module)The final drawing is not a scaled drawing and is a mixture of many different scales.( e.g. a 2 m segment will look e.g 30 cm or a 10 cm segment will look 5 cm on the same view)That's why it is not possible to dimension it with the standard "Creo E/D Modeling" dimensioning functions.The dimensions on the cablingmanufacturing drawings are embedded.The "real length" information is attached to the 2D geometry.The manufacturing drawings are including essential informations like pin, wire, splice and connector properties, wire run lists, bill of materials, connector informations which are used during cable manufacturing process.
Some users can take the E-CAD as base for Cabling, others can take M-CAD as the base for the Cabling generation, therefore we diffentiate between E-CAD centric and M-CAD centric based Harness Drawing creation
1. TopologyWhat is topology ? How is topology influenced ? Example data cables should not be routed together with power cables. But this can not be seen at E-CAD site and can be only differentiated at M-CAD side. 2. LengthTotal wire length and harness segment length3. FixturesThe necessity of special wiring fixtures can be only discovered in MCAD4. Space CalculationQuestion: Do I have enough space to go with those wires ? Analysis of heat transfer can be made in M-CAD only.THEREFORE IT IS NOT POSSIBLE TO MAKE COMPLETE CABLING IN E-CAD ONLY
For manufacturing the cable harness, the necessary data is a drawing, connection list and BOM
Standard solution: E-CAD -> M-CAD one direction. Cabling or E-CAD system can be customized independently. Traditional systemsUni-directional Interfaces are one-way interfaces which mean they can transfer information from a software or data source to another software. For example, a uni-directional interface may be used for directing telephone call costs information of a mobile phone provider to the billing system.
Bi-directional interfaces are two-way interfaces which can transfer data in both directions between the source and destination system.
E-CAD InterfaceConnectors are placed interactively or automaticallyAny wirelist data from E-CAD systems could be intelligently imported into Cabling ensuring an accurate transfer of electrical intent into the mechanical design. This interface is the bridge between E-CAD and M-CAD departments.The format of the file is simple and in ASCII FROM TO WIREdev1 CADModel1 pin1 dev2 CADModel2 pin2 Dia Colordev1 CADModel1 pin1 dev2 CADModel2 pin2 Dia Colordev1 CADModel1 pin1 dev2 CADModel2 pin2 Dia Colordev1 CADModel1 pin1 dev2 CADModel2 pin2 Dia Color+ can be generated by "any" E-CAD system on the market, which has a "customizable" wire list output+ even if the output is not customizable, any file can be "post-processed" to look like how we want+ in combination with the "automatic channel routing" it allows "full automatic error free 3D Harness design"+ no user interaction - no errors + no "forgotten" wiresDynamic comparison of the wirelist and the modelspace for missing and not yet placed components or cables.Recognition of connections in the modelspace, which are not listed in the wirelist.Automatic air-net cable connections for individual connections, cable groups or for the complete scheme at once.+100 % match between E-CAD & M-CAD design- needs tight connection between E-CAD & M-CAD departments concerning ECAD part numbers and CAD models
Cabling is an open package which allows customization and add-ons to be integrated into the system in LISP language or CCF Format
