• When you report form characteristics, like Flatness, in
Calypso, the result is determined by the distance
between two perfect pieces of geometry, “squeezed” as close together as possible containing the actual
measured points of the feature.
• This is calculated by default using a special Evaluation
Method, called “Minimum Element”.
• Note that this result for Flatness (form) is different than
the FORM listed in the feature’s window of Calypso, as that is typically calculated using the LSQ Evaluation
Method.

• When reporting Parallelism of one plane to another in
Calypso, the result can be thought of as the distance
between two planes, parallel to the datum, that contains
all of the actual measured points of the feature being
evaluated.
• By default, the LSQ evaluation method is used to
determine the orientation of the Datum.
• Note that in the Parallelism Characteristic, secondary
datums are not necessary if you are evaluating two 3-
dimensional features, like planes.

• When you report “Profile” of a 3-D geometric feature in Calypso, the default result can be though of as the
thickness of a zone, centered on the nominal geometry of
the feature being reported, that contains all of the
measuring points of the feature.
• By its nature, “Profile” is a combination of size, form, orientation, and position errors.
• Calypso uses your Feature Nominals to determine the
“target” shape and location of the feature.
• *When reporting Profile, MAKE SURE ALL YOUR
FEATURE NOMINALS ARE CORRECT, including A1 and
A2 projection angles.

• The next several slides show the results for Flatness,
Parallelism, and Profile for five different point patterns on
the surface to be evaluated.
• Notice how position, orientation, and form errors in the
points that make up the evaluated surface affect the
results of Flatness, Parallelism, and Profile.
• Actual characteristic windows from Calypso are shown,
along with explanations of why each result is calculated
the way it is.
