Hi guys,

Is there a difference in interpretation between the two scenarios?

So is it your belief that the use of the word "INDIVIDUALLY" in scenario #2 nullifies the requirement that the features be related to each other? In other words, the lower segment is no longer a FRTZ?

It is not FRTZ either way.

You have two separate requirements, as if you applied two FCFs "not touching" each other.

FRTZ only exists if you have compound FCF.

 
Hi All,

No difference.

I agree with CH that the special rules that go along with FRTZF's only apply in the context of composite FCF's. John's example has multiple single-segment FCF's.

I believe everything above is correct. There is no difference between the two. However, I do not see the need for the word INDIVIDUALLY in this case. It is superfluous in its meaning.

Is there a possibility this can mean something other than what it says without the word 'individually' being used?

I have six holes that when related to A and B, must be within a profile of .5 (like a positional tolerance). And each hole individually must be within a roundness of .1. Right?

My other question is - Is there a SIMULTANEOUS requirement for the .5 profile wrt A and B? Is that assumed because it refers to all six holes? I do not believe there is unless that is specified.

I would like to learn something now.
