Struct SeamTolerance 

#[non_exhaustive]
pub struct SeamTolerance { /* private fields */ }

The tolerance a vertical profile’s seams are checked against.

Build it from the model with SeamTolerance::for_model, from a known precision with SeamTolerance::from_precision, or use SeamTolerance::strict for the floating-point rounding term alone.

Implementations

impl SeamTolerance

pub const MAX_PRECISION: f64 = 1e-3

The coarsest precision honoured, in metres.

A file declaring a coarser Precision is checked at 1 mm instead: a step a surveyor could see is never joined on the file’s say-so.

pub fn strict() -> Self

Only the floating-point rounding term: 1e-9 * max(|a|, |b|, 1).

pub fn from_precision(precision_metres: f64) -> AlignmentResult<Self>

Accept length seams within precision_metres, capped at Self::MAX_PRECISION.

Errors

Refuses a negative or non-finite precision with AlignmentError::InvalidUnits.

pub fn for_model(model: &Model, units: AlignmentUnits) -> AlignmentResult<Self>

The tolerance the model itself declares.

Reads Precision from every IfcGeometricRepresentationContext whose CoordinateSpaceDimension is 3 and takes the coarsest, converted from the project length unit with units.length_to_metres. No declared precision gives Self::strict.

Errors

Refuses invalid units, and a declared Precision that is not a finite, positive number (InvalidAttribute naming the context).

pub fn length(&self) -> f64

The absolute length tolerance in metres, after the cap.
