View on Flathub ↗

Musa CAD is a 2D drafting application for technical, architectural and engineering drawings. It follows AutoCAD's ribbon, command line, prompts and shortcuts, so a drafter's habits carry over, and its multi-threaded, GPU-accelerated core keeps even large drawings smooth to pan, zoom and edit.

Features:

  • Lines, polylines with widths, arcs, circles, ellipses, splines, hatches and gradients
  • Move, copy, rotate, scale, stretch, trim, extend, fillet, offset and arrays, with grips
  • Object snaps, polar and object snap tracking, and dynamic input at the cursor
  • Dimensions, leaders, text, tables and geometric tolerancing
  • Layers, linetypes, lineweights, blocks with attributes and external references
  • Layouts with viewports, and plotting to PDF or a printer
  • DXF read and write; DWG through the free ODA File Converter
  • Several drawings open at once in tabs
