Creo Parametric Tip: A Design Consideration When Creating a Flat Pattern for a Complex Harness

This question was originally asked by a former student who attend the Creo Parametric Cable and Harness Design course and was answered by the class instructor. 

 

Student's Question:

What is the best method of creating a flat pattern for a complex harness? Even when I try manual, there is still a branch that won’t let me select it for a start point.

 

Instructor's Answer:

A possible solution to creating your flat harness linked to a complex assembly is to use a sub-harness.

In your harness part, you can create a sub-harness or sub-harnesses. A sub-harness is a portion of a harness (and not a separate part file); It is visible in the model tree in the harness Footer area. Using this you can possibly break up the wire features in “groups” that can be managed a little easier in the flattened harness model.

You can use all of the entities available for harnesses when working with sub-harnesses, but Creo allows you to also work with sub-harnesses separately in Harness Manufacturing mode.

(SIDENOTE: Harness-MFG module is used to create flattened harnesses from 3D harness parts).

To set the default sub-harness, use the MODIFY HARNESS icon located in the Harness group in Cabling mode. Then select the harness that includes the sub-harness you wish to set as the default. You can then click on Set Default and select the desired sub-harness.
