@ifc-lite/drawing-2d

2D architectural drawing generation from 3D IFC models. Produces section cuts, floor plans, and elevations as vector SVG with proper architectural conventions.

Installation

npm install @ifc-lite/drawing-2d

Quick Start

import { generateFloorPlan, exportToSVG } from '@ifc-lite/drawing-2d';

// Generate a floor plan (meshes, elevation, options?)
const drawing = await generateFloorPlan(meshData, 1.2);

// Export as SVG
const svg = exportToSVG(drawing, { showHatching: true });
