**Tolerance ID 107** **-- Diameter of 10 ±0.1:**

The Least Material Condition Local Size (LMLS), Maximum Material
Condition Local Size (MMLS), and since "(E)" is included adjacent to the
tolerance, the measured Mating Envelope (ME) size is also reported. In
this case the Mating Envelope is the maximum inscribed cylinder. The
summary value, 107, for each part is equal to the component value
furthest from nominal.

Note:

In many cases the data requirements will be reduced to only a single
value, since very short features of size will be measured at only one
location and (E) is not been shown. This is understood to be a common
case. The level of rigor for size reporting must be specified by the
controlling authority (design engineer, procurement engineer, etc).

1.  An example to illustrate the local sizes and the mating envelope
    will be added in the future.

**Tolerance ID 200 -- Flatness of 0.1:**

The flatness value for each part is reported. No component values are
reported.

**Tolerance ID 109 -- Perpendicularity with a Cylindrical Tolerance Zone
of diameter 0.1 referencing \[A\]:**

The perpendicularity value for each part is reported. No component
values are reported.

**Tolerance ID 108 -- Position with a Cylindrical Tolerance Zone of
diameter 0.2 referencing \[A,B,C\]:**

The Y\[A,B,C\], and Z\[A,B,C\] components are reported at each end of
the hole using a decimal number suffix (.01, .02) to identify the
location, and Y & Z appended to the end of each suffix to identify the
component direction. The summary, position value for this cylindrical
zone is the larger of the two values from each end of the hole,
calculated by multiplying the hypotenuse of the triangle formed by the Y
and Z components by two. The triangle is formed by the deviations of
each component from its nominal value (e.g. the deviation for 108.01Y is
-0.023). This calculated diameter represents the size of a Tolerance
Zone which would just contain the controlled component of the Feature.

[Note:]{.underline}

If the drawing does not include labeled axes of the Datum Reference
Frame, then view-dependent directions, X horizontal and Y vertical may
be used, but this does not yield an origin from which positive and
negative directions can be identified. This is therefore not a
recommended method.

**Tolerance ID 101 -- Position with a Slab-like Tolerance Zone of
thickness 0.8 referencing \[A,B,C\]****:**

The Y\[A,B,C\] components for each end of the hole are reported using
the same convention as #108# above. The summary value for #100# for each
part is equal to the absolute value of the largest deviation multiplied
by two. This represents the size of a Tolerance Zone which would just
contain the controlled component of the Feature.

**Tolerance ID 100 -- Surface Profile with a Skin-like Tolerance Zone of
thickness 0.08 referencing \[A,B,C\]:**

The surface deviation of each measured point is reported as component
("C") data. A positive value indicates a "plus material" (i.e. more
material than nominal) condition, a negative value indicates a "minus
material" (i.e. less material than nominal). For each component the
point number is indicated with a decimal suffix number appended to the
Tolerance ID (e.g. .01, .02, .03, etc). The profile value for each part,
reported using the assigned Tolerance ID, "100" is calculated from the
components for each part. The profile value equals the largest surface
deviation component's absolute value, multiplied by two.

**Tolerance ID 113 -- Position with a Slab-like Tolerance Zone of
thickness 0.2 referencing \[A,B,C\]:**

This data is reported just as for Tolerance ID 101, above, but with the
difference of the coordinate values being oriented to the datum
reference frame axis Y2\[A,B,C\].
