Real jobs, real numbers
For reference: manual nesting typically runs 65–75% utilization.
Independently benchmarked
We ran Lapas Core v1.1 head to head against Deepnest on 37 nesting cases: same parts, same plates, same time budgets, then scored every result with an independent program that reads the output geometry. On the standard density tests Lapas left 13.9% of the plate as offcut against Deepnest's 26.7%, and on real jobs it fits the same parts on fewer plates. Fewer plates means lower material spend on every run.

How it works
If you can upload a file, you can use Lapas.
Drop in your DXF or SVG. Set how many of each part you need.
AutoCAD, SolidWorks, Fusion 360, FreeCAD: all supported.
Enter sheet dimensions, kerf width, and how long the optimizer may search.
Multiple sheets, rotation rules, and grain direction supported.
Download DXF or PDF report. Ready for the machine or your customer.
See sheets needed, utilization %, and part placement.
Lapas doesn't replace your CAM. It hands back a nested DXF. Lead-ins, kerf compensation, and cut sequencing stay in the tools you use today. If your machine reads DXF, it works with Lapas.

A real job at your volume
Steel fabrication, Spain put 180 parts on 4 plates instead of 6, using 92% of every plate, in 35 seconds.
Assumes optimized utilization reaches 85%, in line with the customer jobs shown above and in the panel. Actual savings depend on part complexity, material type, and operator method.
Shops using Lapas
Four real jobs, run by Lapas customers on their own parts. Every number below came off the job itself.
Steel fabrication · Spain
Lapas used 4 plates. The same parts laid out at 65% would take 6.
180 parts, 92% of every plate used, done in 35 seconds.
Design engineering
Lapas used 18 plates. The same parts laid out at 65% would take 22.
295 parts across 18 plates instead of 22, in under three minutes.
Sheet metal · Argentina
Lapas used 4 plates. The same parts laid out at 65% would take 5.
A full production run nested in under three minutes.
Toolmaking · United States
The kind of batch that takes an operator most of a morning by hand.
Plate comparisons take the same total part area laid out at 65% utilization, the low end of what hand nesting typically achieves. Your own result depends on your parts.

Features
Not a bloated CAM suite. Just a nesting engine that works.
Parts pack by their real shape, not bounding boxes. Curves, arcs, and irregular shapes fit tight.
Keep remnant sheets in inventory and Lapas fills them before it opens a fresh plate.
Watch parts drop onto the sheet in real time. See utilization climb as it runs.
Drag or rotate any part to clear a clamp or a flaw in the plate. The export matches what you moved.
Works with AutoCAD, SolidWorks, Fusion 360, FreeCAD - upload and nest in one step.
Machine-ready DXF output in one click. PDF reports for quoting customers.
No download. No IT. Windows, Mac, Linux, tablet - all work.
From the founder
"I build nesting algorithms for a living, and I kept hearing the same thing from small shops: the good nesting software costs more than the laser's monthly payment, and the free tools are abandoned. Lapas is my answer - a serious nesting engine at a price a three-person shop can justify. Try it on your own files and email me what's missing. I read every message."
How Lapas gets better
FAQ
Short answers to the things people ask most.
Nesting is free and unlimited - upload your DXF and see the full layout, no part cap, no credit card. The free plan includes 5 project exports a month (any format); re-exporting a project you already exported is free for a week. Pro removes the export cap - $49/month, or $39/month billed annually.
Only taking files out: downloading a project as DXF, SVG, G-code, PLT, or the PDF report. Nesting, re-nesting, changing spacing, swapping sheet sizes, and viewing the full layout never use one. Exporting a project uses one export, and re-exporting that same project is free for 7 days afterwards.
Between your CAD and your CAM. You export flat parts as DXF from CAD, Lapas arranges them on the sheet, and you take the nested DXF into your existing CAM software - which still handles lead-ins, kerf compensation, and cut sequencing exactly as it does today. Nothing about your machine setup changes.
They stay yours. Files are transferred over encrypted HTTPS, processed to compute the layout, and never shared with anyone or used for anything else. You can delete your files and your account at any time.
Almost certainly. Lapas reads DXF files from AutoCAD, SolidWorks, Fusion 360, FreeCAD, and all standard CAD tools. It handles LWPOLYLINE, CIRCLE, ARC, SPLINE, and nested INSERT/BLOCK entities. SVG is also supported.
No. Lapas runs in your browser. No download, no IT. Works on Windows, Mac, Linux, and shop-floor tablets.
Most shops see 15–30% better utilization vs. manual nesting. Typical results vary by job type and current method. Try the ROI calculator above to estimate your savings - or better, run one of your own jobs through the free plan and compare.
Compatible with most CNC cutters: fiber/CO₂/diode lasers, plasma, waterjet, CNC routers, knife cutters. Export your nested layout as DXF - compatible with virtually all CAM software and controllers.
Deepnest is a free desktop tool that hasn't been updated since 2021. Lapas is browser-based, actively maintained, handles DXF natively, has live preview, and exports to DXF and PDF - with real human support.
