@ifc-lite/sdk

The scripting SDK for ifc-lite: a single bim.* API for BIM automation. One context object exposes querying, properties, mutations, viewer control, exports (CSV, glTF, STEP, HBJSON), IDS validation, BCF collaboration, clash detection, 2D drawings, schedules, lists, lenses, and element creation. The same API runs embedded in the viewer, connected across tabs, in Node scripts via the CLI (ifc-lite eval / ifc-lite run), and inside the QuickJS sandbox.

Install

npm install @ifc-lite/sdk

Usage

import { createBimContext } from '@ifc-lite/sdk';

// Embedded mode (local backend)
const bim = createBimContext({ backend: myLocalBackend });

// Connected mode (cross-tab)
import { BroadcastTransport } from '@ifc-lite/sdk';
const transport = new BroadcastTransport('ifc-lite');
const remote = createBimContext({ transport });

// Use the API
const walls = bim.query().byType('IfcWall').toArray();
bim.viewer.colorize(walls.map(w => w.ref), '#ff0000');

Namespaces
