W24SizeTolerance

W24SizeToleranceFitsizeISO¶

Fitsize tolerances following the DIN EN ISO 286-1 system.

PAYLOAD DICT		EXAMPLE
blurb	`str` String representation of the item for human consumption	k7
toleration_type	`W24SizeToleranceType` W24SizeToleranceType for deserialization	`W24SizeToleranceType.FIT_SIZE_ISO`

W24SizeToleranceOffSize¶

PAYLOAD DICT		EXAMPLE
blurb	`str` String representation of the item for human consumption	0.5/-0.2
toleration_type	`W24SizeToleranceType` W24SizeToleranceType for deserialization	`W24SizeToleranceType.OFF_SIZE`
deviation_lower	`float` Lower deviation from the nominal size	0.5
deviation_upper	`float` Upper deviation from the nominal size	-0.2

W24SizeToleranceGeneral¶

Indicates that the General Tolerances apply. The General Tolerances are typically defined on the Title Block. At this stage, we do not extract the information from the title block. If this is relevant to you, let us know.

PAYLOAD DICT		EXAMPLE
blurb	`str` String representation of the item for human consumption	0.5/-0.2
toleration_type	`W24SizeToleranceType` W24SizeToleranceType for deserialization	`W24SizeToleranceType.OFF_SIZE`

W24SizeToleranceTheoreticallyExact¶

Theoretically Exact Measures after ISO 5458 must not be tolerated. They are indicated by a small rectangular frame.

Example:

    +------+
    |  15  |
    +------+

NOTE: In practice, we see Technical drawings contain tolerated, theoretically exact measures.

Example:

    +------------+
    | 15 +/- 0.2 |
    +------------+

In these situations the toleration takes priority.

PAYLOAD DICT		EXAMPLE
toleration_type	`W24SizeToleranceType` W24SizeToleranceType for deserialization	`W24SizeToleranceType.THEORETICALLY_EXACT`

W24SizeToleranceMinimum¶

Some drawings indiate a minimal length for some measures.

Example:

    min. 20

In this case we will return a W24SizeToleranceMinimum.

PAYLOAD DICT		EXAMPLE
toleration_type	`W24SizeToleranceType` W24SizeToleranceType for deserialization	`W24SizeToleranceType.MINIMUM`

W24SizeToleranceMaximum¶

Some drawings indiate a maximal length for some measures.

Example:

    max. 20

In this case we will return a W24SizeToleranceMaximum.

PAYLOAD DICT		EXAMPLE
toleration_type	`W24SizeToleranceType` W24SizeToleranceType for deserialization	`W24SizeToleranceType.MAXIMUM`

W24SizeToleranceApproximation¶

Some drawings indiate an approximate length for some measures.

Example:

    ~ 20

In this case we will return a W24SizeToleranceApproximation.

PAYLOAD DICT		EXAMPLE
toleration_type	`W24SizeToleranceType` W24SizeToleranceType for deserialization	`W24SizeToleranceType.APPROXIMATION`
