CenterHole

The CenterHole model records a center hole that the drawing specifies by a standard (for example DIN 332-A 2,5x5,3 or ISO 6411-A 2/4.25). It stores the standard and the form as written, the pilot and outer diameters where the drawing states them, whether the hole must, may or must not remain on the finished part, the quantity, the label as it appears on the drawing, and a confidence score.

requirement follows ISO 6411. A center hole marked "optional" on the drawing is PERMITTED: it may remain on the finished part but is not required.

Bases: Feature

Represents a center hole specified by a standard (e.g. DIN 332-A 2,5x5,3, ISO 6411-A 2/4.25).

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 number of center holes or instances. Must be at least 1. TYPE: `int`
`standard`	The standard the center hole is specified by, as written on the drawing. TYPE: `str`
`form`	The form defined by the standard (e.g. `A`, `B`, `R`), if stated. TYPE: `str \| None` DEFAULT: `None`
`pilot_diameter`	The diameter of the pilot hole (e.g. `2.5` in `A 2,5x5,3`), if stated. TYPE: `Size \| None` DEFAULT: `None`
`outer_diameter`	The outer diameter of the countersink (e.g. `5.3` in `A 2,5x5,3`), if stated. TYPE: `Size \| None` DEFAULT: `None`
`requirement`	Whether the center hole must, may or must not remain on the finished part, if stated. TYPE: `CenterHoleRequirement \| None` DEFAULT: `None`

Whether a center hole must remain on the finished part (ISO 6411).

REQUIRED: the center hole is required on the finished part.
PERMITTED: the center hole may remain, but is not required (often written as "optional").
NOT_PERMITTED: the center hole must not remain on the finished part.
