@ifc-lite/ifcx

IFC5 (IFCX) parser for IFClite. Parses JSON-based IFCX files with ECS composition, USD geometry, and federated layer support.

Installation

npm install @ifc-lite/ifcx

Quick Start

import { parseIfcx, detectFormat } from '@ifc-lite/ifcx';

// Detect file format
const format = detectFormat(buffer); // 'ifcx' | 'ifc' | 'glb' | 'unknown'

// Parse IFCX file
const result = await parseIfcx(buffer, {
  onProgress: ({ phase, percent }) => console.log(`${phase}: ${percent}%`),
});

console.log(`${result.entityCount} entities, ${result.meshes.length} meshes`);

Features

Native IFC5 (IFCX) JSON parsing
ECS composition (Entity-Component-System)
Pre-tessellated USD geometry extraction
Federated layer support with property overlay
Compatible with existing ifc-lite data pipeline
Format auto-detection (IFC4 STEP vs IFC5 IFCX vs GLB)
IFCX export/write support

Federated Layers

import { parseFederatedIfcx } from '@ifc-lite/ifcx';

const result = await parseFederatedIfcx([
  { buffer: baseBuffer, name: 'base.ifcx' },
  { buffer: overlayBuffer, name: 'overlay.ifcx' },
]);
// Properties from overlay take precedence over base
