GD&T Composite vs. Multiple Single-Segment Lesson 14 - NO MATH

My most advanced GD&T lesson yet! When someone asks about composite position vs. multiple single-segment I usually reach for the standard to refresh my memory. From now on I'll just watch this video at 2x speed!

If you're here because you're looking at a print with THREE or more segments, relax. With composite, every segment after the first one follows the same rules. The position tolerance value is the zone for the features relative to each other. If any datums are specified, they control rotation.
For multiple single-segment, you probably already guessed, additional segments are like another "little brother". They have their own "room" (symbol) and can be evaluated as if they live by themselves. I believe that's why the latest edition of the Y14.5 standard states PLTZF and FRTZF don't apply to multiple single segment, because the rules are technically the same regardless of if there are multiple segments or a SINGLE segment. But either way I don't think it helps most peoples' understanding of the concept so I just threw it in at the end of the video.
If anyone happens to have insider knowledge of why the standards committee made a change here, please enlighten us all in the comments. I'd love to hear from you!
