Parametric CAD
for makers

Sketch, extrude, fillet and print – on your Mac, iPad and iPhone. Everything runs on your device: no account, no cloud, your files stay yours.

Coming soon to the App Store Source code

One app for Mac, iPad and iPhone. Your projects follow you through iCloud Drive.

A real CAD, built for the things you make

Brackets, enclosures, gears, replacement parts: design them precisely, change a number and watch the part follow.

Constraint sketches

Lines, arcs and circles with dimensions and constraints that hold your intent. Points snap to edges, centres and the grid.

Solid modelling

Extrude, revolve, fillet, chamfer, shell, ISO threads, patterns, mirror and booleans on a proven geometry kernel.

Fully parametric

Every step stays editable. Variables drive sizes, so a whole part adapts when you change one value.

Push and pull

Drag a face or an arrow to resize it directly. meerCAD writes the change back into the design history.

Made for touch and Pencil

On iPad, draw with the Pencil and navigate with your fingers. On the Mac, mouse and keyboard shortcuts you already know.

Print and cut

Export STL and 3MF for your 3D printer, DXF and SVG for laser cutting, STEP for other CAD tools.

Same projects everywhere

Projects are plain files in iCloud Drive, so they show up on your Mac, iPad and iPhone without a meerCAD account.

Works with AI assistants

Connect an assistant such as Claude through MCP and watch it model in the app, with a preview before anything changes.

Private by design

No account, no tracking, no analytics. meerCAD makes no network connections of its own.

Start from an example

Open one of the ready-made parts and change its variables: plates, boxes, flanges, gears, hinges and more.

  • Clear, human-readable .meercad files you can keep in git
  • English and German interface
  • Undo everything, rebuild in milliseconds
