## Overview

This DWG viewer renders AutoCAD drawings directly in your browser. DWG is the native drawing format of AutoCAD and the de facto standard for 2D/3D CAD in architecture, engineering and construction. Pick a sample drawing or choose your own .dwg file to preview it instantly, with no upload and no CAD software installed.

## When to use

- You received a .dwg file and want to view it without AutoCAD.
- You need a quick, private preview of a CAD drawing before opening it in design software.
- You want to check a drawing on a machine without CAD tools.

## How it works

- Select a built-in sample drawing or choose your own .dwg file.
- The viewer parses the drawing and renders it in your browser — nothing is uploaded.
- Pan and zoom to inspect the geometry, blocks and layout.

## Use cases

- Previewing architectural and engineering drawings.
- Checking CAD files received from contractors.
- Viewing DWG drawings on machines without AutoCAD.

## Frequently asked questions

### Does it support all AutoCAD versions?

DWG has evolved across many versions (R14, 2000, 2018, etc.). The viewer handles common DWG versions for in-browser preview; very old or newest-version-specific features may render with limitations.

### Are my DWG files uploaded?

No. Drawings you open from your device stay on your device and are parsed locally. Only the public sample drawing is requested from the server.

### Can it edit DWG files?

No, this is a viewer only. It renders the drawing for inspection without uploading; use dedicated CAD software for editing.
