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 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:
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.
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:
Modifying the bend angle and radius dimensions
Using FLATTEN > Move Segment
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. Creo Parametric uses this side to flatten the cables. Click Close Loop to close the leftover side after the cables are laid out.
