Enum Representation 

pub enum Representation {
    ExtrudedAreaSolid {
        profile: Vec<[f64; 2]>,
        direction: [f64; 3],
        depth: f64,
    },
    TriangulatedFaceSet {
        vertices: Vec<[f64; 3]>,
        faces: Vec<[u32; 3]>,
    },
}

The geometry of one element, in its own local coordinate system.

Variants

ExtrudedAreaSolid

A closed profile swept along a direction.

Covers walls, slabs, columns, beams, openings, ducts, and pipes — the large majority of real building elements.

Fields

profile: Vec<[f64; 2]>

The profile in the local XY plane: counter-clockwise, with no repeated closing point. Invariants come from cadforge_geom::Profile.

direction: [f64; 3]

Sweep direction in local space.

depth: f64

Sweep distance. Always positive — a negative depth is normalised into the direction when the representation is built, because IFC requires IfcExtrudedAreaSolid.Depth to be positive.

TriangulatedFaceSet

Explicit triangles, for geometry no recipe can express.

Fields

vertices: Vec<[f64; 3]>

faces: Vec<[u32; 3]>

Implementations

impl Representation

pub fn extrusion( profile: Vec<[f64; 2]>, direction: [f64; 3], depth: f64, ) -> Self

Build a swept solid, normalising a negative depth into the direction.

pub fn is_native_parametric(&self) -> bool

Whether this survives export as editable parametric geometry.

pub fn ifc_representation_type(&self) -> &'static str

The IfcShapeRepresentation.RepresentationType this maps to.

pub fn ifc_item(&self) -> &'static str

The IFC entity name of the representation item.

pub fn is_valid(&self) -> bool

Structural check before export. A malformed representation must never reach a file.

Trait Implementations

impl Clone for Representation

fn clone(&self) -> Representation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Representation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Representation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Representation

fn eq(&self, other: &Representation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Representation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
