ifc-lite 0.1.0

High-performance Python bindings for the ifc-lite IFC parser

ifc-lite

High-performance Python bindings for the ifc-lite IFC parser.

Installation

pip install ifc-lite

Quick Start

import ifc_lite

# Load an IFC file
model = ifc_lite.process_file("building.ifc")

# List all IFC types in the model
print(model.ifc_types)

# Get all reinforcing bars
bars = model.elements_by_type("IfcReinforcingBar")
for bar in bars:
    print(f"{bar.name}: {bar.vertex_count} vertices, {bar.triangle_count} triangles")
    print(f"  Properties: {bar.properties}")

# Access geometry (vertex positions, normals, triangle indices)
for mesh in model.meshes:
    positions = mesh.positions  # flat list of x,y,z triplets
    normals = mesh.normals      # flat list of nx,ny,nz triplets
    indices = mesh.indices      # triangle indices
    color = mesh.color          # RGBA tuple

API

Module-level functions

• ifc_lite.process_file(path) – Load and process an IFC file from disk
• ifc_lite.process_text(content) – Process IFC content from a string
• ifc_lite.version() – Get the native library version

IfcModel

• model.meshes – List of all MeshData elements
• model.ifc_types – All distinct IFC type names
• model.elements_by_type(type_name) – Filter elements by IFC type
• model.element_by_express_id(id) – Lookup by express ID
• model.element_by_global_id(gid) – Lookup by IFC GlobalId
• model.metadata – Schema version, entity counts, coordinate info
• model.stats – Processing timing statistics

MeshData

• mesh.express_id, mesh.ifc_type, mesh.global_id, mesh.name
• mesh.positions, mesh.normals, mesh.indices, mesh.color
• mesh.properties – IFC property set values (dict or None)
• mesh.vertex_count, mesh.triangle_count
