Nestpact is free online DXF nesting that runs entirely in your browser. Upload a sheet and your parts as DXF, let the optimizer pack them with true-shape collision detection, and download the nested DXF ready for your CAM or cutter. No install, no four-figure license.
It started from a simple frustration: nesting software was either an expensive desktop license or a toy that only packed rectangles. We wanted the thing every job shop actually needs, so we built it for the browser.
What you can do
- DXF upload for sheets and parts, with arcs, splines, and blocks handled properly.
- True-shape nesting with configurable rotation, gap, and edge offsets.
- Hole filling: small parts nest inside the cutouts of bigger ones.
- Multi-sheet overflow when one sheet is not enough, and a live preview while the optimizer runs.
- Nested DXF download, ready for your CAM software.
Everything since, the G-code generator, 3D model import, the NFP true-shape engine and the part library, builds on that foundation. Read how the no-fit-polygon engine interlocks concave parts, or start nesting your own DXF now.
