Short question:
What is the difference in interpretation of following two cases of composite positional tolerancing?
I know what Y14.5M standard says, but I am afraid I am not able to visualize this difference properly.
Again, sorry for the delay, but ... it's Summer finally.
I've added to the PowerPoint Show file that I posted earlier, to show a few more variations for further discussion. Before anyone comments, yes, a couple of animations are out of order and some of the animations don't keep the "child" zones absolutely within the "parent" zones; PowerPoint isn't my favorite tool for functionality.
Anyway, I think that the graphics mostly speak for themselves as to what the controls mean. Hopefully it helps.
