GM ABSOLUTE 0,0,0
GM ABSOLUTE 0,0,0
(OP)
I work for a tier 1 supplier to GM. I am being asked to start designing our components with the absolute 0,0,0 at a given point on our component. I have always designed our components in vehicle position. The way I look at this, if I follow this request when GM drops my component into Team Center it’s position will be at the front, center of the vehicle and will have to be repositioned.
My thinking is that they are asking for a saved WCS to be at this given position on my component, but it still should be designed IVP.
What do you guys think?
Thanks,
Dave

I would interpret what GM wants as modeling the part at absolute 0,0,0. When your part goes into TcAE, there won't be a vehicle...it will just be your part/assembly by itself...GM will then add it as a component to the vehicle assembly later, if they desire.

Putting each part at its own 0,0,0 forces the assemblies to use mating conditions for all components. We had that in our UG standards.

In the past, GM designed all parts IVP and simply placed them at absolute 0,0,0 when adding them to an assembly. This created a lot of rework on assemblies. GM is trying to get the most out of it's assemblies and this is just another step in that direction.
Another reason is for part reuse. A part can be used in any vehicle where it has application. The Vehicle Assembly determines it's location.
I was involved in a lot of discussion regarding this topic during my 15 years at GM. The end users have been reluctant to use mating conditions because the old way has worked for so long. I believe that once they see the benefit of mating conditions they will have a change of heart.
