Assistance Translating Feature Control Frame to Layman's Terms
(OP)
Hello All -
Within the attached drawing, there is a feature control frame highlighted in red. Can you please relay, in plain language, what this frame means?

Thanks for your time thus far!
Note: I have intentionally deleted some dimensions within the attached file as it is customer owned.

Envelope (tolerance zone) has got diameter 0.35 not 0.3 when the toleranced feature is at its minimum material condition.

To recap (just to be sure I'm understanding correctly), since there is an "M" (maximum material condition) in the feature control frame, this denotes that a bonus tolerance is permissible.
AT MMC: The tolerance window is simply as stated in the frame control frame. As stated above, at a 4.05 feature diameter there is a 0.25 dia tolerance window between the axis of the 6.18 feature and the 4.00 feature.
AT LMC: The bonus tolerance comes into play and at a 3.95 feature diameter, the tolerance window is 0.35 in dia. This 0.35 tolerance window is calculated by taking MMC-LMC (4.05-3.95 = 0.10) and adding it to the tolerance stated within the control frame (0.10 + 0.25 = 0.35).
Thanks, again!
