CAD File Viewing Without AutoCAD

CAD (Computer-Aided Design) files contain technical drawings, 3D models, and engineering specifications. These files typically require expensive specialized software like AutoCAD, SolidWorks, or Fusion 360. Our browser-based viewers render CAD files using JavaScript libraries, providing instant preview without software licenses or installations.

Supported CAD Formats

DXF (Drawing Exchange Format) is an open CAD format widely used for 2D and 3D drawings. Originally developed by Autodesk for AutoCAD interoperability, DXF files can be viewed and manipulated without proprietary software.

STL (Stereolithography) files represent 3D models as triangular meshes, commonly used for 3D printing. Our viewer renders STL files with rotation, zoom, and measurement tools.

Gerber / PCB Files

Gerber files define printed circuit board (PCB) layers for manufacturing. Our viewer renders copper traces, silkscreen, solder mask, and drill layers, allowing verification before sending to fabrication.

Common Use Cases

Client review: Share designs with clients who don't have CAD software installed
Cross-platform viewing: View CAD files on devices without Windows or specialized software
Quick inspection: Preview drawings received via email before downloading large CAD applications
3D print preparation: Verify STL model geometry before sending to 3D printer
