Dimension

The Dimension model captures a single dimensional annotation extracted from a drawing. It preserves the measured value, units, and tolerance scheme, along with the label as it appears on the drawing, the number of instances the callout applies to, and a confidence score. Through the tolerance details it records whether the dimension is theoretically exact, a reference value, or covered by a general tolerance. This normalized representation lets you run tolerance stack-ups, generate inspection plans, or compare revisions to see how sizing has changed without reinterpreting each drawing manually.

Bases: Feature

Represents a measurement cue in an engineering or technical drawing.

PARAMETER	DESCRIPTION
`reference_id`	Reference ID to identify the object. TYPE: `int`
`label`	A short description of the feature in a human-readable format. TYPE: `str`
`confidence`	Confidence in the feature extraction or interpretation. TYPE: `Confidence \| None`
`quantity`	The quantity or value associated with the measurement, must be non-negative. TYPE: `int`
`size`	Details about the size, including type, nominal value, tolerance, and unit. TYPE: `Size`
