Online DWG / DXF Viewer

About this Online CAD Viewer

Autodesk AutoCAD files (.dwg and .dxf) typically require expensive software to view. Our free Online CAD Viewer allows you to instantly open and view your 2D CAD drawings directly in your web browser. Whether you are an architect reviewing blueprints, an engineer checking mechanical parts, or a student learning CAD, this tool saves you time and money. All processing is done locally in your browser, ensuring your proprietary designs remain completely private and secure.

How to Use the DWG/DXF Viewer

1. Open your file in AutoCAD (or any CAD software).
2. Save or Export the file as a DXF format (AutoCAD R12 or 2000 version works best).
3. Click the upload box above and select your .dxf file.
4. The tool will instantly parse the coordinates and render the 2D geometry on the dark canvas.

Frequently Asked Questions (FAQ)

Can I open .dwg files directly?

The .dwg format is a closed, proprietary binary format owned by Autodesk, which makes it difficult for free web tools to read. However, .dxf (Drawing Exchange Format) is the open-standard text version of DWG. You can easily save your DWG as DXF in AutoCAD and upload it here.

What entities does this viewer support?

This lightweight parser supports the most common 2D drawing entities: LINES, CIRCLES, ARCS, and POLYLINES. It automatically calculates the bounding box of your drawing to scale and center it perfectly on the screen.
