DXF writer for CNC.
Add rectangles and circles, set their sizes (mm), and export one DXF where every shape is packed side-by-side — never overlapping. Preview before you export, or import each list from CSV.

CSV format
Each table imports its own CSV, sizes in millimetres. Lines starting with # are ignored, and a non-numeric header row is skipped automatically.
Rectangles — width,height
100,60 80,80 120,40
Circles — radius
30 20 45
Output is an AutoCAD R12 DXF (layer CUT) that opens in LibreCAD, AutoCAD, Fusion 360, and any CNC / laser CAM software. Shapes are packed into a roughly square block with the gap you set — none overlap.
