i see that the 3D continuity and PLM were separated in the I4.0 slide. My initial understanding was PLM helps to provide 3D continuity. In team center there is an MPP offering which fits the bill on virtualization. My question: Are there any standards or consortium like (MESA) which governs on what set of functions a PLM should and should not perform. Please elaborate on what is deciding and driving the best practices in PLM world to realize digital twin concepts.

One more comment here.... In case of the flight door, and the animation that I saw here, this design has been in use in many passenger aircrafts for many years. A big metal lever that is physically worked to release open the door and the door lifts open, and as designed, the door is part of aircraft body design. So, just to voice my design idea, can this door section be a feature that slides into the body, instead of flinging open...? The direction of the slide when closed, is in line with the direction of the flight of the plane so that the sealing on the door has added air pressure acting on the door to keep it shut during flight. The mechanism to open or close it form the inside of the aircraft is managed by physically operated levers, the aesthetic value of the design on the inside of the aircraft is much neater and might use less space and less intrusion in the cabin. Again, this is just my comment....
