Download the beta (.dmg) All releases and checksums

Requirements

System
macOS 15.6 or later, on Apple silicon (M1 or newer)
Download
About 30 MB. Signed and notarized by Apple, so it opens without a Gatekeeper warning.
Python
Bundled. No system Python or packages to install.
Network
None. No account, no telemetry, no update check. Your documents stay on your disk.

The download button always points at the newest release. Each release on GitHub lists its SHA-256.

What the beta does

  • Sketch and constrain — points, lines, arcs, circles, ellipses and splines, with geometric constraints, dimensions and shared variables. A badge shows when a sketch is fully constrained and which constraints conflict.
  • Build bodies — extrude, revolve, multi-section loft and sweep; booleans with an optional smooth or chamfered seam; edge rounding, draft and twist.
  • Compose assemblies — define a part once, instance it, and mate instances onto named anchor points.
  • Standard parts library — NEMA steppers, hobby servos, metric fasteners, bearings, gears, T-slot extrusion and more, inserted with a live preview.
  • Export — bodies to 3MF, STL, OBJ and glTF (.glb, .gltf), with per-body colours and finishes where the format carries them; sketches to DXF and SVG.
  • Bring your own AI — every document is ordinary Python, so any coding agent can write and refactor your models. See the AI page.

Known limits

  • No STEP export. FlywheelCAD builds meshes from signed distance fields — the same class of kernel as OpenSCAD — not boundary representations.
  • No 2D drawing sheets. Sketches export as DXF and SVG.
  • macOS on Apple silicon only.
  • It is a beta: report problems on GitHub.
