One model.Every trade.The whole plan set.

FrameMind Linework is a CAD for building and planning, native on the Mac. Buildings, roads, sewers and utilities take shape in one file, together with the drawings, schedules and calculations an office hands in. Duck, the built-in assistant, works with the same commands you do.

Version 0.19.2 from 13 November 2026, for Apple silicon. Windows is in preparation.

FrameMind Linework with the Bachhausen town hall: trade layers on the left, the 3D model with the square in the middle, the building’s key figures on the right, the sheet bar at the bottom.

The Bachhausen town hall in Linework: 3,570 objects, 58 sheets, one file. The bar beneath switches between the model and its sheets, as in the app. Bachhausen town hall

One ground floor, four trades.

These four sheets of the town hall show the same window onto the same model. Move a wall, and the next time they are drawn it stands in its new place on all four.

Plotted from rathaus.frame at 1:50. A click opens the whole sheet.

Duck draws with the same commands you do.

The assistant doesn’t click around the interface. It calls the commands you type too, and you see each one in the command line.

How Duck works


  • Every command is a tool.

    354 of the 365 commands are open to Duck, from wall to heatload. Opening, exporting and deleting files stays with you.

  • One undo for the whole run.

    Duck takes back only its own steps, never yours.

  • Agents in the open drawing.

    Claude Code and other agents work over MCP in the running app, locally on your machine, while you watch.

Together on one file.

Share with one click: a link to view and measure in the browser, another to draw along in the app. Plus versions, reserving and working on without a connection. The server for it is still in test operation.

Working together

Your files stay yours.

DWG and DXF in both directions, IFC, PDF and PDF/A, LandXML, ISYBAU, GAEB X31, Shapefile and GeoJSON, MVR. The native .frame format is readable JSON.

All formats

What is still missing.

  • Windows. The build is prepared but not finished. Today Linework runs on Macs with Apple silicon.
  • Experience from offices. The examples are made up; no office has handed in a real project with Linework yet.
  • Verification. Calculations are preliminary sizing from your input values. Tables from standards are not built in, and responsibility stays with the planner.
  • Apple’s notarization. On first start you have to allow the app in System Settings.
