GeneralTolerances

GeneralTolerances captures the default tolerance regime declared in a drawing, such as ISO 2768 classes or company-specific tables. The model records the standard referenced, the tolerance class, unit system, and any notes about applicability. This information governs dimensions that do not have explicit tolerances, so surfacing it programmatically is critical for downstream planning. Use the object to set baseline inspection limits, calculate fit scenarios, or flag when a drawing relies on outdated standards. When combined with individual dimensions, the model allows automated systems to derive complete tolerance bounds without manual lookup, and it supports quality audits by documenting which global assumptions applied to each revision.

Bases: Reference

Model representing general tolerances for a part or drawing.

General tolerances are applied to dimensions where specific tolerances are not explicitly defined. These tolerances are governed by recognized standards and principles.

PARAMETER	DESCRIPTION
`reference_id`	Reference ID to identify the object. TYPE: `int`
`tolerance_standard`	The standard used for general tolerance definitions, e.g., DIN 7168 or ISO 2768. TYPE: `GeneralTolerancesStandard`
`tolerance_class`	The tolerance class or grade, defined as a short string such as 'm', 'f', or 'c'. TYPE: `str \| None`
`principle`	The principle governing the tolerance application, such as independence or envelope. TYPE: `GeneralTolerancesPrinciple \| None`
