Selecting Features to Measure
When selecting the features for measurement, consider which feature
is better suited or required by design constraints to be the origin feature
(Measure From). Selection order
is especially important when you select Normal
to Origin Feature in the Analysis
Results PropertyManager under Analysis
Parameters.

In this example, you create a study to determine the minimum result
for the inside distance between the two vertical legs.
|
|
|
|
|
|
The only tolerances you apply are perpendicularity tolerances to the
base. |
|
|
|
|
|
These tolerances result in this worst case part. |

When you evaluate the measurement along the X-axis, the minimum distance
between the two sides is not dependent on the Measure
From feature, which results in a distance of 34. |

Select Normal to Origin Feature.
When you use the left leg for Measure
From, the result is 34.8.
Note how the dimension rotates to be perpendicular to the Measure
From feature. |

|
|
|
|
When you use the right leg for Measure
From, the result is 32.8. |
