| Symbol |
Check: The software checks to ensure the
geometric characteristic and feature combination is valid. An error
occurs if the combination is invalid, for example, if you apply
Flatness when the toleranced
feature is a Boss. |
| Tolerance Zone Shape |
Filters: The
software filters the options based on the selected geometric
characteristic. For example, the options are enabled for Position tolerances and disabled for
Circularity tolerances. Check: The software checks to
ensure the tolerance zone and feature combination is valid. An error
occurs if the combination is invalid, for example, if you apply a
diameter symbol when the toleranced feature is a plane.
|
| Material Condition Modifier |
Filters: The
software filters the options based on the selected geometric
characteristic. For example, the options are enabled for Position and disabled for Runout. Checks:
- The software checks to ensure the maximum
material condition (MMC) and least material condition (LMC)
symbols are applied only when the toleranced feature is a
feature of size. An error occurs when the feature is not a
feature of size, for example, when the feature is a pocket.
- The software checks to ensure a size tolerance
is applied to the toleranced feature when you specify MMC or
LMC. An error occurs when a size tolerance does not exist.
|
| Projected Tolerance Zone |
Filters: The
software filters the options based on the selected geometric
characteristic. For example, the options are enabled for Position and disabled for Concentricity. Checks:
- The software checks to ensure the toleranced
feature supports a projected tolerance zone. An error occurs if
the feature does not. For example, if you apply a projected
tolerance zone when the feature is a plane (ISO).
- The software checks to ensure the toleranced
feature supports a projected tolerance zone. An error occurs if
the feature does not. For example, if you apply a projected
tolerance zone when the feature is a plane (ISO).
|
| Unit Basis Tolerance |
Check: The
software checks to ensure the format used for the per unit area or per
unit length criteria is valid. An error occurs when the format is not
recognized. |
| Tolerance 2 |
Check: The
software checks to ensure the format of the input, tolerance value
followed by “MAX”, is valid. An error occurs when the format is not
recognized. |
| Primary, Secondary, and Tertiary Datum |
Filters:
- The software filters the datum options based on
the selected geometric characteristic. For example, the options
are enabled for Position
and disabled for Flatness.
- The software filters the options for the
material condition modifiers based on the selected geometric
characteristic. For example, the options are enabled for
Position and disabled
for Runout.
Checks:
- The software checks to ensure the entered datum
label is the label of an existing datum. An error occurs when it
is not.
- The software checks to ensure MMC and LMC
symbols are only applied when the datum feature is a feature of
size. An error occurs when the feature is not a feature of size,
for example, when the feature is a plane.
- The software checks to ensure the datums define a valid datum reference frame based on the rules specified by ASME Y14.5.1M. An error occurs for nonconforming datum sets, for example, if the primary and secondary datums are two parallel planes.
|
| Composite Frame |
Check: When you specify datums, the
software checks to ensure the datums specified in the lower tier are
entered in the same order of precedence as the upper tier. An error
occurs if the datums do not repeat, for example, if the primary datum in
the upper tier is “A,” but “B” is entered as primary in the lower tier.
