Enum Measure 

pub enum Measure {
    Linear {
        a: P2,
        b: P2,
        along: P2,
    },
    Radial {
        center: P2,
        radius: f64,
        diameter: bool,
    },
    Angular {
        vertex: P2,
        from: P2,
        to: P2,
        sweep: f64,
    },
}

What a dimension measures, where it is in the plane.

Variants

Linear

From a to b, along the direction along: an aligned distance along b - a, a horizontal or a vertical one along an axis.

Fields

a: P2

b: P2

along: P2

Radial

The radius of a circle — or, diameter, its diameter.

Fields

center: P2

radius: f64

diameter: bool

Angular

The angle at vertex between its sides along the directions from and to, measured turning sweep radians counter-clockwise from from.

Fields

vertex: P2

from: P2

to: P2

sweep: f64

Implementations

impl Measure

pub fn lines(&self, label: P2) -> Vec<Vec<P2>>

The lines it is drawn with when its value is shown at label: for a linear one, extension lines from what it measures out to a dimension line through the label, along what it measures — and on to the label if it is beside them; for a radial one, a leader from the centre — a diameter’s from the far rim — across the circle, out to the label if it is beyond the rim; for an angle, an arc about its vertex through the label, and its sides out to the arc. None for what has no direction to be drawn along.

pub fn arrows(&self, label: P2) -> Vec<(P2, P2)>

Its arrowheads, as drafting draws them, with its value at label: each tip, and the unit direction it points in. A linear dimension’s point out from between its extension lines, a radius’ out at the rim — a diameter’s at both rims — and an angle’s along its arc, out at either end.
