Is SilentCAD free to use in the browser?

Yes. Open silentcad.com/app and model: no account and no install. The desktop builds are optional and add offline work and local project files.

Do I need CAD experience?

No. The loop is place, cut, combine, finish, export. Fusion history and isolation are there when the sketch becomes a real part, not before.

Which files can I export?

STL for printing, 3MF for multi-object prints, DXF for 1:1 drawings, SVG for an outline, CSV for the parts list, and the project file with full history.

Are the units millimetres?

Yes, internally and in every export. The interface can display inches, but the geometry stays in millimetres and DXF is 1:1.

Does it work offline?

The browser app works once loaded; the Linux, macOS and Windows builds run locally and keep projects in the Documents folder. Linux auto-updates; macOS and Windows are manual downloads.
