xeokit AutoCAD DXF Loader

Imports AutoCAD DXF documents — the open ASCII (or binary) sibling of DWG — as SceneModels. Strokes from LINE / LWPOLYLINE / CIRCLE / ARC, fills from 3DFACE, recursive INSERT block expansion, TEXT / MTEXT rasterised as textured quads.

DXF is open ASCII and the SDK parses it in-tree — no third-party library or adapter to wire. The parser lives in ./versions/v1_0/parse.ts; DXFLoader is a thin façade. Internally the parser builds a DWGDocument and hands it to the shared DWG emission pipeline (so DXF and DWG share their entire SceneModel-emit code path — only the parser differs).

Usage

import {Scene} from "@xeokit/sdk/model/scene";
import {DXFLoader} from "@xeokit/sdk/formats/dxf";

const scene = new Scene();
const sceneModel = scene.createModel({id: "plan"}).value!;

const dxfText = await fetch("/plan.dxf").then(r => r.text());
await new DXFLoader().load({fileData: dxfText, sceneModel});

Exporting a SceneModel as DXF

Pair-wise with the loader, DXFExporter writes a SceneModel back out as ASCII DXF (AutoCAD R2000-compatible). Triangle meshes become 3DFACE entities, line meshes become LINEs, point meshes become POINTs; one DXF LAYER per SceneObject. Per-mesh colour round-trips via DXF's true-colour group code 420.

import {DXFExporter} from "@xeokit/sdk/formats/dxf";

const dxfText = await new DXFExporter().write({sceneModel});
