Struct Profile2D 

pub struct Profile2D {
    pub outer: Vec<Point2<f64>>,
    pub holes: Vec<Vec<Point2<f64>>>,
}

2D Profile with optional holes

Fields

outer: Vec<Point2<f64>>

Outer boundary (counter-clockwise)

holes: Vec<Vec<Point2<f64>>>

Holes (clockwise)

Implementations

impl Profile2D

pub fn new(outer: Vec<Point2<f64>>) -> Self

Create a new profile

pub fn add_hole(&mut self, hole: Vec<Point2<f64>>)

Add a hole to the profile

pub fn center_on_bbox(&mut self)

Translate the profile so the centre of its outer bounding box sits at the origin.

IFC parameterised profiles (I/U/L/T/C/Z/…) are defined centred on their bounding box, and the swept-area Position placement is applied relative to that centred origin. Some per-shape builders are easier to read when written from a corner; centring them here in one place keeps every parametric profile consistent with the spec. Holes are shifted by the same offset so they stay aligned with the outer boundary. No-op for profiles that are already centred.

pub fn make_outer_ccw(&mut self)

Reverse outer when it winds clockwise, so the counter-clockwise contract on outer holds however a builder listed its points. Holes are untouched (their contract is clockwise and the hollow builders emit them that way). The extrusion and earcut paths each re-derive orientation and were right either way; the 2D drawing path emits outer verbatim, and that is where a clockwise T or Z showed.

pub fn triangulate(&self) -> Result<TriangulationOf<f64>>

Triangulate the profile using earcutr Returns triangle indices into the flattened vertex array
