True-shape nesting engine
Irregular shapes are rotated and interlocked to squeeze the most out of every sheet — not just bounding boxes. The same class of algorithms that tops international packing research.
Upload your DXF files, set your sheet size, and let our research-grade engine pack your parts tighter — in seconds. Built for laser, plasma, waterjet, plotter and CNC cutting. Save material, save time.
No credit card required · 10 free nestings every month
A focused tool that does one thing extremely well: packing your parts as tightly as possible.
Irregular shapes are rotated and interlocked to squeeze the most out of every sheet — not just bounding boxes. The same class of algorithms that tops international packing research.
Nest across as many sheets as your job requires, mix sheet sizes, and know exactly how many sheets to load into the machine.
Set per-part quantities and allowed rotations — lock the grain direction when the material demands it.
Small parts are automatically nested inside larger cutouts, and every layout reports its reusable offcut so remnants go back to stock, not to the bin.
Your files are stored securely and visible only to you. The Pro plan adds zero-knowledge encryption, so even we cannot read your parts.
Download the nested layout as DXF for a single sheet, SVG for a preview, or a ZIP for the whole job — straight to your machine software.
The engine
Most online nesters hide their algorithm. Ours is built on published, peer-reviewed research — the same class of methods that tops international 2D packing studies.
NestorCut's engine is built on sparrow, the state-of-the-art strip-packing heuristic from KU Leuven, and a dedicated exact collision engine. Not a greedy first-fit — a modern separation-and-compaction optimizer.
After minimizing the used length, the whole layout is transposed 90° and re-optimized in a tight corridor — forcing parts into pockets other tools leave empty.
Small parts are nested inside the cutouts of larger ones as a first-class feature of the solver — often the single biggest source of savings on real-world jobs.
Thousands of placement orders are explored in parallel. You get several distinct alternative layouts — densest, largest remnant, balanced — and keep the final say.
Results keep improving the longer the engine runs, within your plan's compute budget. And identical jobs produce identical layouts — every single time.
Perfect nesting is NP-hard — no one can guarantee a provably optimal layout. We get remarkably close in seconds, and we show you the numbers so you can judge.
Drag and drop your DXF files. Each part is validated, rebuilt and previewed automatically.
Enter your material dimensions, part spacing (kerf) and rotation constraints.
Compare the best alternative layouts, pick one, and download a ready-to-cut DXF — with the material you saved, in black and white.
One saved sheet of material usually covers the month.

Nesting is the process of arranging 2D parts on a sheet of material so that as little as possible is wasted. A good nesting engine rotates and interlocks irregular shapes to minimize scrap — directly cutting your material bill on every job.
Yes. Every account gets 10 free nestings every month, no credit card required. If you nest more often, the Unlimited plan starts with a 7-day free trial: you are not charged until the trial ends, and you can cancel anytime before then.
NestorCut works with DXF files — the standard exchange format for laser, plasma, waterjet, plotter and CNC cutting. The output is a clean DXF per sheet (plus SVG previews and a ZIP of the whole job) that loads directly into your machine software.
Yes. Small parts are automatically placed inside the cutouts of larger ones, and a two-phase compaction pass pushes parts into remaining pockets. That is where the biggest material savings usually hide.
Your uploaded files and results are stored securely and are only visible to your account. For maximum confidentiality, the Pro plan adds zero-knowledge encryption: your files are encrypted with a key only you hold, so even we cannot read them.
Yes. If you only nest occasionally, credit packs are available — each nesting operation simply consumes credits from your balance. No recurring commitment.
You can cancel your subscription at any time — cancel during the 7-day trial and you will not be charged at all. And if a paid subscription does not meet your expectations, you can request a full refund within 30 days, no questions asked.
Perfect nesting is a computationally hard problem with no guaranteed optimal solution. NestorCut uses a modern separation-and-compaction engine with simulated annealing and a two-phase bi-axial pass to deliver dense, practical layouts — and shows you several alternatives so you keep the final say.
