Breaking External References in Creo 4.0 and Creo 5.0 

Why did no one show me this before! Its a total game changer. Usually my models are a fragile disaster of external references and I never understood how people did any design without them. This makes so much more sense.

Very good explanation, thx a lot!

Great video, helps a lot

Thank you!

I am not able to find the backup refernece option here in my creo. Could you please help ?
