W24SizeTolerance

W24SizeToleranceFitsizeISO

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

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.

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.

W24SizeToleranceMinimum

Some drawings indiate a minimal length for some measures.

Example:

    min. 20

In this case we will return a W24SizeToleranceMinimum.

W24SizeToleranceType.MINIMUM

W24SizeToleranceMaximum

Some drawings indiate a maximal length for some measures.

Example:

    max. 20

In this case we will return a W24SizeToleranceMaximum.

W24SizeToleranceApproximation

Some drawings indiate an approximate length for some measures.

Example:

    ~ 20

In this case we will return a W24SizeToleranceApproximation.
