NestMaxx

NestMaxx is free, online true-shape nesting software for laser, plasma and CNC router cutting. It packs parts by their real outlines using the No Fit Polygon method, so curved and irregular parts interlock instead of sitting in bounding boxes. Import DXF or SVG files, pick from over 40 parametric shapes, or draw a part in the built-in CAD editor. Nest across multiple sheets, drop small parts into holes, then export the layout as DXF or SVG. It runs entirely on your device, with no sign-up.

NestMaxx arranges 2D parts on sheets of material using their real outlines, rather than their bounding boxes. Its No Fit Polygon method finds placements where parts can sit against their neighbours without overlapping. The software is designed to help users fit more parts on each sheet, reduce scrap, and create layouts for cut-to-shape work such as sheet metal, woodworking, and laser cutting. It runs online and is completely free to use. Users add parts by importing DXF or SVG files, choosing from more than 40 parametric shapes, or drawing in the built-in 2D editor. They set sheet size and spacing, then press Nest to generate a layout. Parts can rotate freely, follow a locked grain axis, or use fixed angles. NestMaxx can fill multiple sheets, flag parts that do not fit, and crop a reusable offcut. Users can export the nested layout as DXF R12 or SVG. NestMaxx is for shops and makers that cut flat material into parts, including sheet-metal fabricators, woodworking shops, and laser-cutting users. The page describes use with plasma, laser, waterjet, CNC routers, and panel saws. It runs online on Windows, macOS, Linux, and Android tablets, with nothing to install. Its free use includes unlimited nesting, a 2D editor, and a library of more than 40 parametric shapes.
