Harness manufacturing

Hi,

i'm new on CREO (3 month). new job new company.

i used to work on different software to create 3D harnesses.

i have an issue today regarding Harness Mfg. we just got the licence

i try to flatten simple harness. it work (sometime) but when i want to use a component

to route my harness sometime it will work and sometime i got the following message:

Unsupported Axial Topology

when i remove the component from the path it will be ok, but i use the same component 

somewhere else and it is working fine so i don't understand what is happening.

i think the part i use to route the wire is created properly as it is working fine somewhere else

if someone has an idea i will appreciate.

Thanks
