    pub field_key: String,
    pub point_a: [f64; 3],
    pub point_b: [f64; 3],
    pub value: f64,
    pub label: String,

}
Expand description

One editable dimension annotation.

LINEAR: a leader from world point_a → point_b whose length is the (resolved) value of param field_key; dragging projects the pointer onto the a → b axis.

ANGULAR: a screen-constant-radius ARC swept value degrees about axis (unit), starting from ref_dir (unit, in the plane ⟂ axis), centered at center; dragging maps the pointer to a swept angle. The point_a/point_b / midpoint() linear surface is unused for an angular annotation (both are set to center); the app anchors an angular chip at the arc’s mid-sweep, which is camera-dependent and computed engine-side.

Fields§

§field_key: String

The inputParams key this annotation edits (e.g. sizeX, radius, arc).

§point_a: [f64; 3]

LINEAR: the dimension’s start point in WORLD space (the leader anchor / drag base). ANGULAR: center.

§point_b: [f64; 3]

LINEAR: the dimension’s end point in WORLD space (the value-1 handle). ANGULAR: center.

§value: f64

The current (resolved) numeric value of field_key (a length for LINEAR, DEGREES for ANGULAR).

§label: String

The short display prefix (X, R, H, A, Arc, …).

§kind: FeatureDimKind

The annotation kind.

§center: [f64; 3]

ANGULAR only: the arc center (the axis-plane vertex) in WORLD space. [0;3] for a linear annotation.

§axis: [f64; 3]

ANGULAR only: the rotation AXIS (unit) the arc sweeps about. [0;3] for a linear annotation.

§ref_dir: [f64; 3]

ANGULAR only: the sweep’s ZERO reference (unit, in the plane ⟂ axis). [0;3] for a linear annotation.

Implementations§

Source§

impl FeatureDimAnnotation

Source

pub fn midpoint(&self) -> [f64; 3]

The world-space midpoint of the leader — where the app anchors a LINEAR label. (Angular chips anchor at the arc mid-sweep, computed engine-side with the camera’s world_per_pixel.)
