HiI am doing a wiring harness in Inventor 2011.Is there a limit to the number of segments you can add? Inventor is not letting me rout cable through more than 3 segments. Is this right? 

Dosent sound right, being limited by that...
 
Then again I have yet to produce 3D cables...But I am interested in what you find out, if anything.
 
Good luck!
 
And the aircraft question, arent they all custom and different anyway? What do you mean by a 'workflow' to create them?
