CAD-N 0.4.0 — first public release

First public release of CAD-N, an open-source 2D true-shape nesting tool for DXF parts on rectangular sheet stock (laser / plasma / router / CNC).

Highlights

• DXF import with layer selection, annotation filtering, hole detection, and robust geometry cleaning (welds loose segments into closed loops)
• Nesting with spacing + kerf clearance, rotations, multi-seed search — every layout is validated overlap-free and in-bounds
• Two stock sizes: define Sheet A + B and get the mix with the least total stock area
• Common-line cutting (opt-in): butting parts share one cut line instead of doubled edges
• Clean DXF export behind a validation gate that refuses to write a bad cut file
• Self-contained JSON jobs, CSV reports, Windows exe

Download

CAD-N.exe below is a self-contained Windows build — no Python needed. Unsigned, so SmartScreen may ask once (More info → Run anyway).

To run from source: see the README.

Licensing

CAD-N is MIT. The exe bundles Qt/PySide6 (LGPL-3.0) and GEOS (LGPL-2.1) as replaceable DLLs — see NOTICE and THIRD_PARTY_LICENSES.md.
