On-canvas measurements for no-go zones, shareable layouts, smarter exports
Draw a defect zone and see its dimensions live, click any zone for size and area, share a read-only layout link, and get self-describing DXF filenames.

What's new in Nestpact
Feature releases, nesting engine upgrades, and notes from building a DXF nesting tool for laser, plasma, waterjet, and CNC router shops. Every major feature lands here with the date it shipped.
The genetic optimizer learned true-shape geometry
The genetic preset now runs NFP candidates at full strength, scores layouts on trapped voids, and is guaranteed to never pack fewer parts than simpler strategies.
Read more →NFP: true-shape nesting that interlocks concave parts
A new top-tier preset built on No-Fit Polygon geometry. L-brackets, jigsaw profiles, and other concave parts now lock together instead of wasting their bounding box.
Read more →Stop conditions: tell the optimizer when good enough is good enough
Stop the nest the moment every part is placed, when scrap drops below a target percentage, or after a time budget you set.
Read more →Photograph your sheet, trace its defects
Scan a QR code with your phone, photograph the actual sheet, and the photo appears under the canvas so you can trace knots, rust, and damage as no-go zones.
Read more →Saved presets, part labels in DXF, and BOM import
Save your machine setups as one-click presets, engrave part names into the exported DXF, and load a cut list straight from a CSV.
Read more →Your parts, on file: the per-user part library
Save parts you cut repeatedly into a personal library and drop them into any future job without re-uploading the DXF.
Read more →Sample gallery, shop-floor PDF report, offcut library, and job costing
Try the nester with one click, print a placement report for the floor, bank your leftover sheet as a reusable offcut, and put a price on every nest.
Read more →Plans, subscriptions, and verified accounts
Nestpact grows up: subscription plans with feature tiers, secure checkout, and email-verified accounts.
Read more →Tabs, router mode, and a 3D toolpath viewer
Uncut tab bridges hold parts in the sheet, router mode adds real Z motion with stepdown passes, and the NC viewer goes 3D.
Read more →Drop in a 3D model: STL, OBJ, PLY, and 3MF import
Upload a 3D solid and Nestpact finds its largest flat face, projects the silhouette, and nests it like any DXF part, with thickness detected automatically.
Read more →From nest to machine: G-code export with lead-ins and layer routing
Generate machine-ready NC code for laser, plasma, and waterjet straight from the nested layout, with lead-in/out, per-layer operations, and a built-in simulator.
Read more →The free DXF health checker
Open contours, duplicate entities, and stray geometry break nests and cuts. The checker finds the problems and fixes most of them automatically.
Read more →Hello, Nestpact: free online DXF nesting
Upload a sheet and your parts, get an optimized true-shape layout, download the nested DXF. The story of why we built a nesting engine for the browser.
