Coming from AutoCAD

  • Draw & dimension

    Lines, polylines, circles, hatches, text, leaders, and real dimensions — with the object snaps, ortho, and typed distances a drafter expects.

  • Layouts & print to scale

    Model space plus paper layouts with scaled viewports. Export a PDF that measures true on paper — 1:50 means 1:50.

  • Works with DXF & DWG

    Import and export both. Deliver to and receive from any CAD, with an honest account of what maps and what flattens.

  • Parametric blocks

    Blocks are small programs — typed parameters in, geometry out. Change a bolt count on a placed block and the drawing recomputes.

  • AI agents

    Let an agent draw, annotate, or write custom blocks for you — in the editor, in Claude, or in batch scripts.

  • Yours, offline

    Drawings are .linea files on your disk. The app installs as a PWA and keeps working without a network.
