Version 1.1 Released 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.

01 · Fit check

Too big for the sheet? You hear before the run

No waiting for a nest that was never going to place that part.

When you press start, every part is measured against the usable area: the sheet less its border. A part that cannot fit is listed before anything runs, with what it needs and what the sheet allows.

The usual causes are named with it: a bigger sheet, a smaller border, or leaving the part out. Since 1.5 the same dialog fixes it in one click.

Fit check
A part too long for the sheet is caught before the run starts A long bar lies straight across the sheet and overhangs the usable area by 64 mm, shown in red. The Start button turns disabled, a note says 1 part does not fit, and the list names the bar: it needs 1064 mm and the sheet allows 1000 mm. The bar stays in the job. +64 mm Start Start 1 part doesn't fit Bar · needs 1064 mm — sheet allows 1000 mm
The bar needs 1064 mm and the sheet allows 1000. Start waits until you decide.

02 · Units

Inch files at the right size

A part drawn in inches does not come in 25.4 times too small.

When a DXF or SVG says what units it is in, Lapas uses them and scales the part for you.

When it does not say, Lapas makes an assumption from your metric or imperial setting and tells you: We assumed mm - switch if that's wrong. One click switches every file in the upload that did not declare its units, and a line stays on the part so you can switch back.

If reading a file in inches would make it bigger than any plate, the banner says that too.

Units
A DXF without units: assumed mm, switched to inches in one click A DXF file that declares no units is imported. Its parts come in tiny next to the sheet, because they were read as millimetres, and a banner says We assumed mm with the choices Keep mm and Switch to inches. Switch to inches is pressed, every part scales up by 25.4 together to a sensible size on the sheet, the banner goes, and a quiet line says Imported as inches. DXF · no units in file × 25.4 We assumed mm Keep mm Switch to inches Imported as inches
No units in the file, so mm was assumed. Switch to inches, and every part takes its real size.

03 · Layout check

Every layout checked before you get it

No overlapping parts and nothing hanging off the plate, on any result.

Every finished layout is checked again against the real part outlines, separately from the search that made it: no two parts overlapping, and no part past the sheet edge. A part sitting in another part's hole is allowed, as it should be.

A layout that fails the check is never delivered. Lapas tries another way, or the job fails with a clear message.

The live preview shows work in progress. Only the checked final layout reaches the result and the export.

Smaller changes

  • Fast, Optimized, Quality

    Choose how long Lapas searches for a better layout on a slider marked Fast, Optimized and Quality, instead of typing seconds. Big jobs get more time on their own.

  • Pan and zoom the result

    Every sheet sits side by side on one canvas: scroll to zoom at the cursor, drag to pan. The live preview uses the same view.

  • Better SVG and DXF text

    SVG files can hold several shapes, and can be kept as one rigid part. DXF text comes in with every letter.

  • Engrave layers ride along

    Decorative engrave or mark layers stay with their part.

  • Clearer import errors

    Files that fail to read say why.

  • Decimal commas

    Numbers typed with a comma are accepted, and the PDF report lists the parts next to each sheet.

  • Rate a result

    Tell us how a nest came out, straight from the result.
