Question

Harness drawing best practices (Help!)

I am very new to cabling and I'm in the process of creating my first flat harness drawing. Flattening the harness took a little time to figure out, but now that I'm creating the drawing I realize the flatten state is a bit of a mess and I'm probably not doing things the correct way. I have been unable to find tutorials or documentation to point me in the right direction, so I figured I would ask here.

 

Below is a screen shot from my drawing showing what is possibly the worst location of my harness. I have two connectors that plug into a controller and two bundles that go in different directions (one large bundle, one small bundle). I realize that this is nearly impossible to put any dimensions on:

What I would like to get to is something more like the image below where the two connectors split off and simple length dimension can be added. I know that I can change the cable from thick to centerline view, but I still have a mess of individual wires (which are driving my pin tables) and I don't see a simple way to make a simple centerline from the bundle to the connector.

What is the best way to clean this up so that a) my individual wires are still routed correctly and driving my pin tables and b) my harness will flatten with a simple/single centerline from the main branch to the connector?

    Hello TractorGuy,

     

    Thank you for posting this request.

    In order to help you, PTC proposes trainings and tutorials around cabling.

     

    For trainings requests you can access to: https://www.ptc.com/en/ptc-university/instructor-led-training/?utm_source=Learning_Connector&utm_medium=remarketing&utm_campaign=Training_General_Learning_Connector_CLC&utm_content=Training_General_Learning_Connector_CLC-remarketing-Ad_banners_for_Learning_Connector_site-43676&cl1=Training_General_Learning_Connector_CLC-remarketing-Ad_banners_for_Learning_Connector_site-43676&cmsrc=Learning_Connector&cid=7015A000001ULQdQAO&elqCampaignId=25434&product=creo&category=cabling

     

    For tutorials please visit: https://learningconnector.ptc.com/search/tutorials?product=Creo%20Parametric&category=Cabling

     

    Hope this will help you to get better result with HMX.

    "Take training" is not really an answer to my question.

    Hi TractorGuy

     

    What about the tutorials?

    Ok, 3 months later and I'm no closer to making a usable drawing for constructing a wiring harness. I can not understand how anyone keeps their sanity using this software to do anything productive. Here is a short list of the issues I can not resolve:

     

    • I can not keep the connectors in line with the harness. My connectors have even numbers of wires which means I have to flatten to one side or the other and can not keep it centered.
    • It is impossible to fan out all of the wires to a connector unless you want to spend an entire day adding bends and twists to the wires so they will reach.
    • Connectors do not stay with backshells. I have a 90° 64 pin connector that has a backshell which assembles correctly to the harness. I still have not determined how to get the connector to come in and assemble to the backhshell correctly and it is always angled in the wrong plane.

     

    Seriously, how the hell do people make wiring harness drawings with this garbage?

    Take a look at Harness manufacturing extension (hmx)

    But from Creo 3, I think...
