Module analytic_export 

Optional analytic descriptions of authored geometry, keyed by product occurrence. This walks the same body-representation selection as the mesh router, but does not produce meshes. Source operands of booleans are identified as such.

Structs

AnalyticQuantitySources

Three analytic source views from one bounded representation walk. This is useful for quantity joins that need exact swept-disk world directrices and reusable disk/extrusion definitions with matching occurrence ordinals.

AnalyticSourceKey

Stable within and across reads of the same IFC bytes.

DirectrixMetrics

Measurements of a complete occurrence directrix in absolute IFC world space.

DirectrixSegmentMetrics

Per-segment measurements in metres and radians, in directrix order.

ExtrusionDefinition

One authored extrusion before product or representation-map placement. source retains raw IFC file units and separate profile/solid positions.

ExtrusionDefinitions

Bounded exact source/occurrence view; never substitutes tessellated loops.

ExtrusionNominalQuantities

Nominal source-solid quantities in raw IFC file-length units. A product’s occurrence transform, openings, and other boolean operations are excluded.

SweptDiskCheckError

A caller-supplied tolerance is invalid.

SweptDiskCheckFinding

One measured source-geometry finding. next_segment_index identifies the second side of a join and is absent for a finding on one segment.

SweptDiskCheckOptions

Tolerances in world metres and radians. All must be finite and nonnegative.

SweptDiskCheckReport

Diagnostic report for the authored source before any enclosing CSG change.

SweptDiskDefinition

Original IfcSweptDiskSolid geometry in IFC file length units.

SweptDiskDefinitions

Bounded source/instance view of authored swept disks.

SweptDiskDescriptions

Analytic swept disks in IFC Z-up, absolute-world metres.

SweptDiskInstance

One use of a source solid. Matrix is column-major f64 and maps raw IFC source coordinates directly to absolute IFC Z-up world metres. It includes model length units, object placement and every enclosing mapping transform.

SweptDiskNominalQuantities

Derived measurements in square and cubic metres for one uncut source solid. The volume and lateral areas are section × centreline estimates; they do not account for self-overlap, mitred joins, or later boolean operations.

SweptDiskOccurrence

One authored IfcSweptDiskSolid in an occurrence’s body representation.

Enums

AnalyticSourceContext

A context is a top-level representation for a direct solid, or the ordered IfcRepresentationMap IDs for a mapped solid. MappingTarget IDs are excluded so occurrences of one map share their source definition.

SweptDiskFindingCode

Stable machine-readable source-geometry finding codes.

Functions

check_swept_disk

Check an extracted world-space swept disk without decoding or tessellation. Findings concern source geometry only; they do not certify a bar for cutting, bending, material, or building-code compliance.

extract_analytic_quantity_sources

Extract all quantity source views in one canonical walk. Existing individual APIs keep their output and budget contracts unchanged.

extract_extrusion_definitions

Opt-in exact source/instance view of IfcExtrudedAreaSolid occurrences. Source profiles and depths retain IFC file units; each f64 occurrence matrix maps solid-local source coordinates to absolute IFC Z-up metres.

extract_swept_disk_definitions

Opt-in source/instance view. Definitions stay in raw IFC file units; occurrence matrices map those raw coordinates into absolute IFC Z-up metres.

extract_swept_disk_descriptions

Extract exact swept-disk definitions for product occurrences, optionally restricted to a set of product STEP IDs. An empty set returns no products. Unsupported directrices are reported in each record’s status; malformed representation walks are reported in diagnostics and omitted atomically for the affected product.

extract_swept_disk_views

Return both world descriptions and reusable raw source definitions in one bounded representation walk. Both views share the same decoded source cache.

extrusion_nominal_quantities

Derive source quantities only when the profile and extrusion are complete. The projected height accounts for an oblique ExtrudedDirection: IFC Depth measures along that unit direction, rather than along the profile normal.

Type Aliases

ExtrusionInstance

A use of an extrusion source. world_from_source maps its solid-local raw coordinates to absolute IFC Z-up metres. Apply the source’s profile and solid Position matrices before this matrix for a profile boundary point.

SweptDiskSourceContext

Compatible name for source contexts returned by swept-disk APIs.

SweptDiskSourceKey

Compatible name for source keys returned by swept-disk APIs.
