Amazed, sorry you were so disappointed. The article was not intended to be all incusive of all the capabilities of various products and processes, but only to provide food for thought.
As one can imagine, the article would get a bit long.

I agree with the need for downstream use and yes, many systems using 3D GD&T are "only" annotation that limits the value. None the less, there is value in "annotation only" detailing on the 3D model versus the 2D drawing. 3D visualization and global collaboration is enhanced and is faster then creating a 2D translation of the design intent. After all, 2D annotations on a drawing do not flow down through downstream processes to well either.

Thanks for you mention on Tecnomatix; you are right. It's another technology that can take advantage of "smart" 3D GD&T. Did I mention AIMS also? Which btw interfaces with Catia as well.
