@file-viewer/renderer-cad

Standalone CAD renderer package for Flyfish File Viewer. It is powered by @flyfish-dev/cad-viewer, previews DWG, DXF, DWF, DWFx, and XPS in the browser, and resolves wasm / worker URLs through the File Viewer asset manifest for offline enterprise deployments.

Usage

import FileViewer from '@file-viewer/vue3'
import { cadRenderer } from '@file-viewer/renderer-cad'

const options = {
  rendererMode: 'replace',
  renderers: cadRenderer,
}

You can also compose it with other renderer packages:

import { cadRenderer } from '@file-viewer/renderer-cad'
import { pdfRenderer } from '@file-viewer/renderer-pdf'

const options = {
  rendererMode: 'replace',
  renderers: [pdfRenderer, cadRenderer],
}

Capabilities

• Supports .dwg, .dxf, .dwf, .dwfx, and .xps.
• DWG is parsed on demand with a worker and LibreDWG WASM to keep the main thread responsive.
• DXF is parsed in JavaScript and normalized into the common CAD document model.
• DWF / DWFx / XPS use the native renderer with dwfv-render.wasm for performant raster / WebGL fallback.
• Includes layer toggling, structure stats, fit-to-view, zoom controls, global toolbar zoom provider, and resize handling.

Offline Assets

The default asset paths are:

• wasm/cad/
• wasm/cad/dwg-worker.js
• wasm/cad/dwfv-render.wasm

For private deployments, override them with options.cad.wasmPath, options.cad.workerUrl, and options.cad.dwfWasmUrl.

Migration Note

CAD preview has moved completely out of @file-viewer/core. Core now only keeps the asset manifest, shared types, and a compatibility error message, and it no longer installs @flyfish-dev/cad-viewer by default. Install this package and pass it through renderers, or use @file-viewer/preset-all for the complete CAD experience.
