Hi John,
I agree that cabling is not the easiest module.
Correcting mistakes in the design could have been a pain in Wildfire 4.0 and before. Plus it was easy to make mistakes. So experience made a real difference in this module.
The correction mechnisms may have not improved much in Creo, but the chance to make mistakes has been significantly reduced with the current workflow. Most pain points currently, are about dealing with legacy cabling assemblies.
But even with the old cersion, thinking of designing the flat harness alone gives me the creep!
I'd rather redo the complete cabling and start all over again with the flat harness, one hand tied to my back, than manually creating a flat harness based on the 3D cabling. I am really curious whether somebody tried this - well, someone without the cabling mode would probably have to...
I really recommend you take another look, because this is exactly what cabling/harness MFG are made for.
