Pro/HARNESS

About Pro/HARNESS
A flattened harness assembly is the 3D cabling harness after it has been laid out on a nail board in the manufacturing assembly. This flattened harness assembly is used to make drawings of the flat harness. It can only be retrieved by either retrieving the manufacturing model or a drawing that references the flattened harness assembly. The flattened harness contains: Three assembly datum planes used for layout and orientation. An assembly coordinate system. The cables are laid out in the XY-plane by default. You can twist the cable out of this plane using FLATTEN > Twist. Flattened harness featuresThese are assembly features created in the flattened harness assembly as you lay out the cables of the 3D harness. These features show the manufactured dimensions, for example, the cable length from one location to another, or the bend radius and bend angle around a pin on the nail board. ComponentsThe connectors at which cables terminate and splices and components, through which they pass, can be assembled to the flattened harness. Wires can be fanned out to the correct entry port on connectors. You can also specify components to be attached to the harness in the 3D assembly, in which case they appear in the flattened harness.
When you begin to manufacture a 3D harness assembly, you are prompted for three object names: Manufacturing model (.mfgnew file) Reference harness part (.prtexisting 3D harness) Note: If there are subharnesses, you can specify one. Flattened harness assembly name (.asmnew file)
The manufacturing model is the upper-level parent for the flattened data and consists of: The 3D harness part as a reference (you cannot see the entire assembly on the screen, but you can see the 3D harness part) The flattened harness assembly Manufacturing information
The flattened harness is automatically updated whenever you make changes in the shape or length of the 3D harness. This lets you create the flat harness at the same time that you route the 3D harness. This manufacturing model pulls in the entire 3D assembly, not just the simplified representation in which the 3D harness was routed for reference.

2. Click Model/Rep to display a different model or simplified representation to control a region. If you change the model associated with the repeat region, the repeat region is populated with the respective data. 3. Select a region. The Open dialog box opens. 4. Select a new part or assembly to be associated with the repeat region.
Tip: Using Subharnesses to Manage Large Designs
With the subharness functionality, you can create subgroups of cables, bundles, and so on in the harness. You can also flatten a harness where portions are not connected or are connected only by being routed to different pins of the same connector, although in different flat harnesses. You can click Add and Remove Cables from a subharness in the 3D assembly as needed to aid in the flattening process. This can be useful to flatten certain portions of a harness automatically without flattening the rest. If you have defined subharnesses for a harness selected in Pro/HARNESS, you are prompted to select a subharness to flatten or select the whole harness when choosing what to flatten. If a subharness is selected, only this subharness is displayed in the reference window, and only cables that belong to it are laid out in that manufacturing model. In general, it is a good idea to use subharnesses, the network of wires, and suppression of some cables to simplify the harness for most of the flattening process. After the main branches of the harness are flattened with the simplified harness, click Resume to move wires that are not flattened to the subharness you are working on to automatically flatten portions of cables that pass through those locations. Use the Fan command to fan the remaining portions of the wires.

Configuring Harness

About Configuring Harnesses
You can preset environment options and other global settings by specifying the required settings in a configuration file. To set configuration options, use the Options dialog box. This help module contains a list of configuration options, in alphabetical order. Each option contains the following information: Configuration option name. Default and available variables or values. The default values are in italics. Brief description and notes describing the configuration option.

Laying Out Cables

About Laying Out Cables
You can use either the Manual Fan or Auto Fan commands to lay out cables. The following commands are available when you click CABLE MFG > Flatten > Lay Out: Set Start PntSelects a location from which to lay out cables. Manual FanLets you decide the locations, bend angles, and bend radius between selected locations. This command is automatically highlighted when a start location has been selected. Auto FanFlattens the harness automatically from the current start point according to system parameters set in the cabling assembly. You can modify the automatically flattened harness as needed. If a loop exists in the reference harness while laying out cables using this command, you are prompted to pick a side of the loop. Pro/ENGINEER uses this side to flatten the cables. You can select this command at any time during the manual lay out procedure to flatten the remaining portions of the harness. Close LoopLets you flatten the open side of a loop, that is, close the loop. You must pick the two ends of the open side, either in the flat harness or in the reference harness. The open side is automatically flattened. The other sides of the loop are not affected. Note: o o You can close other loops till you quit the selection. If the two endpoints of the open side are far from each other, you may need to adjust the bend angle.

Flat OrientLets you select the orientation in which the flat locations of a flattened harness are packed. The orientation is with respect to the flattened harness plane and affects all flat locations in the flattened harness. When you select this command, the FLAT ORIENT menu appears with the following commands: o o HorizontalOrients all flat locations of the flattened harness in a horizontal fashion. VerticalOrients all flat locations of the flattened harness in a vertical fashion.
As you select locations using the Manual Fan and Auto Fan commands on the Lay Out menu, you are laying out the locations and any cables routed between them. If all but one wire is suppressed, and you lay out that wire between two locations, when you resume the other wires, portions routed between locations that have already been flattened are automatically laid out.
You can use this technique to your advantage in simplifying the harness while laying out the main trunk. You can then resume the rest of the wires, and use Auto Fan on the remaining segments. The Manual and Auto Fan commands cannot flatten loop type configurations. For a loop, one leg of the loop is not flattened, but you can still flatten the rest of the harness. Use Close Loop to flatten the remaining leg of the loop.
Tip: Improving Associativity Performance
To manage external references and improve the performance of the flat harness, use the skeleton functionality when routing your harness in 3D. Additionally, place each harness part in a separate subassembly with only the connectors to be used in manufacturing that harness.
To Lay Out Cables Using Manual Fan
1. Click CABLE MFG > Flatten > Lay Out > Set Start Pnt. 2. In the subwindow with the 3D harness, select the location at which you want to start. 3. Select the location to which you want to lay out. This location: o Must be a portion of the same cable selected in Step 3, or at the intersection with a new set of cables, such as where a bundle separates into its constituent cables. Does not have to be the very next location along the cable. You can skip locations, selecting only those that you deem necessary to the laying out of that cable. If you skip locations, you can delete the section and flatten it again to get the skipped locations back, if you want them in the future. 4. In the main window, type a bend radius and bend angle for every segment encountered between selected locations. Type these values in the units of your manufacturing model. The bend angle is in degrees. If you accept the default, the cable is laid out along a straight path. These values create dimensions that you can modify later. 5. Continue to lay out the cable by repeating the selection of a start point. When you reach the end of a cable, or reach the intersection of two cables, possibly where a bundle ends and individual cables start, you must select a new start point. Note: You cannot flatten a 3D cable that branches out from a location that you skipped during the flattening process.

To Lay Out Cables Using Auto Fan
1. Click CABLE MFG > Flatten > Lay Out.
2. Select a start point on an existing harness part location from the subwindow that displays the harness reference part. If this location is deleted in the 3D harness, you must flatten the flat harness again. 3. Select a stable location, marking it with a cabling cosmetic feature. 4. Click Auto Fan and type the minimum bend radius to be used in the flattened harness. It is good practice to specify the lowest number allowed by Pro/CABLING. This number is displayed at the prompt. The harness part is then flattened automatically. 5. Set the fan_significant_locations_only configuration option. If you set the value to yes, only significant locations on the cables are automatically flattened. If you set the value to no, all 3D locations on the cables are automatically flattened. The default is yes. The significant locations are: o o o o o Connector locations, that is, entry port of connecters. Transitional locations where the wire or bundles are not same on both the sides. Branch locations where the wires or bundles do not share the same adjacent location. Cosmetic feature locations where cosmetic features are created. Loom parent locations where branch bundles are located.
Note: The start location of the cable that you have selected using Set Start Pnt is always flattened. 6. Select how you want to orient a harness that has locations with flat grouping. Use the Flat Orient command in the Lay Out menu. The harness is automatically flattened using approximately the same angles that exist on the 3D harness. You can modify the resultant flattened cable segments by: o o Modifying the bend angle and radius dimensions Using FLATTEN > Move Segment
Note: If a loop exists in the reference harness while laying out cables using Auto Fan, you are prompted to pick a side of the loop. Pro/ENGINEER uses this side to flatten the cables. Click Close Loop to close the leftover side after the cables are laid out.
To Add a Twist to a Flattened Harness
1. Click CABLE MFG > Flatten > Twist. 2. Click Add and select the bend arc on the cable where you want to place the twist. If you typed 0 degrees for the bend angle, you cannot add a twist to that cable.
Therefore, modify the bend angle to get an arc segment and perform this procedure again. 3. Type the twist angle to bend the cable out of the XY-plane.
To Remove a Twist from a Flattened Harness
1. Click CABLE MFG > Flatten > Twist > Remove. 2. Select the cable segment that has the twist. After selection, the harness automatically regenerates to display the new geometry. See Also
To Insert a Bend to a Flattened Harness
1. Click CABLE MFG > Flatten > Bend > Insert and select a point on the cable. 2. Type the bend radius and bend angle at the prompt. Note: Bend angles are relative to the previous segment of cable, with positive angles going counterclockwise.

To Insert a Break to a Flattened Harness
1. Click CABLE MFG > Flatten > Break. 2. Click Insert and select the break point on the cable. 3. Type the amount of cable to remove (length of break). The two dimensions that are created are the location of the break with respect to a previous location and the length of the break.
Tip: Breaking Long Segments for Documentation
Long segments can be shortened for documentation purposes by adding a break to the cable. This places an X at the selected point and shortens the cable by a specified amount. Note: Breaks can be added only to the straight segments of a flattened harness.
To Modify the Bend Angle of a Flattened Cable
Click FLATTEN > Move Segment to dynamically modify the bend angle of a flattened cable segment.

Tip: Using Bends

Use a Bend feature to add a bend in the XY-plane to a flattened harness. Two new locations are inserted about the point defining the endpoints of the bend arc. This feature lets you lay out the flat harness on a nail board of a specific size. This feature creates additional locations that are not present in the 3D harness.
Tip: Deleting or Suppressing Cables
You can delete or resume flattened cables. You can suppress failed cables and resume them later if you have corrected the reason that they failed.
To Move a Segment in Manufacturing Mode
1. Click CABLE MFG > Flatten > Move Segment. 2. Select a flattened cable segment. The segment and all segments added after it rotate together dynamically. 3. Click to place the segment or segments at the new angle.
To Delete a Bend in a Flat Harness
1. Click CABLE MFG > Flatten > Bend > Delete. 2. Select the bend to delete. You cannot select a bend that was created by laying out the cable. To remove such a bend, modify the bend angle to 0 degrees. After selection, the harness automatically regenerates to display the new geometry.
To Delete a Flat Cable Segment
1. Click CABLE MFG > Flatten > Delete. 2. Select the cable segment that you want to delete. If this segment has child segments, the CHILD menu appears. You can also delete a flat cable segment using the FEATURE menu. 1. Click CABLE MFG > Feature. The FEATURE menu appears. 2. Click Delete. The DELETE/SUPP menu appears. 3. Select the cable segment that you want to delete. If this segment has child segments, the CHILD menu appears. 4. Click Delete All to delete the entire feature, including the child segments. 5. Click Done.

Using Components in MFG Mode
About Using Components in MFG Mode
Connectors, splices, and components that are marked as attached to a harness in the 3D assembly can be added to, removed from, or redefined in the flattened assembly. Splices and components attached to the harness in the 3D harness are automatically assembled to the flat harness when the cables that go through them are flattened. If these components are disassembled manually, they can be reassembled manually or automatically.
If a component is assembled into a flat harness, it appears in the flat harness assembly BOM. It does not appear in a wirelist unless it is the "from" or "to" for a cable. If cable portions show inside the component, they are not flattened, but show exactly the way they appear in Pro/CABLING. If you select a component to be attached to the harness with the Attach to Harn command in 3D, it is also automatically assembled. Note: Connectors are not automatically assembled when laying out cables. After a drawing of the flattened harness has been created, you can add notes that correspond to the flattened harness.
To Attach Wires to Their Entry Ports
1. Click CABLE MFG > Flatten > Components. The FLAT CONN menu appears. 2. Select either Fan Out or Fan Out All. If you select Fan Out, you are prompted to select an assembled connector whose unattached wires you want to fan out. If you select Fan Out All, all wires are attached to their respective entry ports if their lengths permit it. All the wires attached to this connector in the reference harness are laid out in the flat harness and are automatically routed to their corresponding entry ports.
Tip: Fanning Out Multiple Wires to Components
You can attach multiple wires to multiple entry ports of a component in the flat harness. The component must already be assembled to one wire in the flattened harness before you can use this functionality. Additional wires are attached to their entry ports only if their lengths permit it. Therefore, you must assemble a connector to the shortest wire portion first and then fan out remaining wires. The other types of components automatically assemble to the correct flattened segment that runs through it. Note: Make sure that you route all wires going to the component through a common location before you fan out to the connector in the 3D harness. If possible, route the shortest wire portion straight out from its entry port in the 3D harness. The connector orientation may need to be modified so that the wires can reach the entry ports.

Comparing Information on Flattened vs. 3D Harnesses
You can use Pro/HARNESS to find what has been flattened and what has not, and the correspondence between the flat and 3D harness segments and locations. This lets you find which locations should have connectors assembled. For a 3D harness location, the following information is available: The type of location The connector or component model name, Entry Port Csys, and reference designator (if available) if the type is Entry Port
For a flat harness location, the following information is available: The type of location and feature ID for the corresponding 3D location The connector or component model name, Entry Port Csys, and ref_des (if available) if type is Entry Port Whether the connector or component is currently attached to the entry port (if the type is Entry Port). Whether it was assembled to the location, or the location was fanned out to the entry port.
