Version 1.4 Released August 2026
Fewer sheets, diagonal parts and kits
Repeated parts pack onto fewer sheets, long parts that only fit at an angle now nest, kits stay whole on one sheet, and a short result tells you what is missing with a one-click fix.
- Fewer sheets on many copies. One sheet solved with the most copies, then repeated.
- Long parts nest on the diagonal. A part longer than the sheet is seated on the tilt.
- Kits kept whole. Kit parts fill the gaps, always on one sheet.
- Missing parts, with a fix. What was not placed and why, and Place remaining parts.
01 · Repeated parts
Many copies, fewer sheets
Orders of one part in the hundreds come out on fewer sheets, and on the same count every run.
When a job is many copies of the same part, Lapas Core solves one sheet first: it adds copies until one more no longer fits. Then it repeats that sheet for the rest of the order, instead of packing every sheet from scratch.
Identical rectangles go on an exact grid. Long, thin copies are lined up at one shared angle, so they stack like planks rather than lying every which way. On mixed jobs, whole solved sheets are reused wherever the same set of parts comes round again.
Measured on one job: 400 copies of one bracket on a 4000 x 2000 mm sheet, 10 mm apart. Before, 20 to 22 sheets depending on the run; after, 20 on every run. A job with many different parts gains less.
02 · Diagonal fit
Longer than the sheet, and it still nests
A long bar that only fits on the tilt is nested, not refused.
A part longer than the usable sheet in both directions used to be turned away before the run. Now the check turns the part through every angle the job allows and finds the tilt where it fits.
That needs rotation set to Any angle for that part. With 90° steps a part too long for the sheet is still too long, and the job tells you so before it starts.
A part exactly as large as the usable sheet is no longer dropped from the result.
03 · Kits
A kit comes off one sheet, whole
Every sheet gives you complete sets, and the rest of the job still fills the gaps.
Group parts into a Kit, and the whole kit is nested together, so one sheet gives you a complete set. A kit is never split across sheets.
The kit's parts are nested as free parts, each finding its own gap, instead of being welded into one rigid block. Loose parts from the same job pack in around them.
When the job also pins parts to particular sheets, kits are nested as fixed groups instead, which can pack more loosely.
04 · Missing parts
Short of parts? It says so, with the fix
You see what did not make it before you export, not at the machine.
A result that could not place everything now leads with it: how many parts were placed, which were not, and why, for example that the declared stock ran out.
The alert sits right above the export, with Place remaining parts in the same place. It fills free space on your sheets; the parts already placed do not move.
The result also shows the sheets saved against a simple rectangle layout of the same parts.

Smaller changes
-
Inch DXF
With Imperial units set, the DXF export is written and declared in inches, and true arcs and circles survive the change.
-
Your own machine posts
Clone a built-in machine post and edit it for your own controller.
-
Machine files you can read
G-code comments name each part and say whether a contour is a hole or an outline. Each part is cut holes first, then its outline.
-
Doubled exports
A file with every line drawn twice no longer produces an extra part with no holes.
-
Outlines across two layers
An outline drawn across two colour layers is joined instead of dropped.
-
Group all, ungroup all
One click for files with several shapes.
-
Upload progress per file
Each file shows Queued, Uploading, Reading geometry, Ready or Failed.
-
Reopened jobs stay honest
A reopened job keeps the parts that could not be placed, instead of saying all were placed.
-
Lengths in your unit
Every length is shown in your unit and keeps what you typed. Imperial accounts enter density in lb/ft³.
-
Free plan
Nesting is unlimited on the free plan, with 5 project exports a month.

- 1.4 August 2026 Fewer sheets, diagonal parts and kits Repeated parts pack onto fewer sheets, long parts that only fit at an angle now nest, kits stay whole on one sheet, and a short result tells you what is missing with a one-click fix.
- 1.3 July 2026 Fine-tune the nest, keep the real curves Adjust a finished nest by hand with exact moves, measuring and snapping, pack curved parts into each other, lose half-empty last sheets, and get DXF files that keep your real arcs and layers.
- 1.2 June 2026 Your stock, your angles, your layers Nest one job across several sheet sizes, allow your own rotation angles, and sort cut and engrave layers with rules saved on your account.
- 1.1 May 2026 Clearer results, safer imports A warning before the run when a part will not fit the sheet, inch files at the right size, every layout checked before you get it, and a Fast to Quality speed slider.
- 1.0 Feb–Apr 2026 Lapas launches: true-shape nesting in the browser Upload DXF or SVG parts, watch them nest live by their real outline with small parts inside holes, and take the layout out as DXF, SVG, PLT, G-code or a PDF report.
Don't take our word for it.
Upload one of your own DXF files and see the layout yourself. It's free and takes about two minutes.
