What DXF Cleanup fixes

The problems that make a file look fine on screen but fail on the machine.

Splines & arcs → LINE

Flattens curves to simple LINE geometry that older and budget controllers accept without choking.

Duplicate & zero-length

Detects and removes doubled-up lines and zero-length entities that cause double cuts and burnt edges.

Open polylines & gaps

Closes sub-millimetre gaps so shapes fill and cut as continuous paths.

Unit mismatches

Fixes unit-conversion errors so your part imports at the right size the first time.

Cut order

Re-sequences moves to reduce unnecessary travel between cuts.

Clean R12 output

LINE-only R12 DXF designed for broad CNC, laser, plasma, plotter, and waterjet compatibility.

Deterministic geometry processing

No AI guesswork. The same file, the same clean result, every time.

Every entity in your DXF is read individually — lines, arcs, polylines, splines. Nothing is rasterized or approximated behind your back. What you approve in the free preview is exactly what you download.

Frequently asked questions

Why won’t my DXF import correctly into LightBurn?

Usually it’s splines, unclosed polylines, or duplicate lines. DXF Studio flattens splines and arcs to LINE geometry, closes gaps, and removes duplicates, then exports clean R12 DXF that imports cleanly.

What does the cleanup actually remove or fix?

It flattens splines and arcs to LINE entities, removes duplicate and zero-length geometry, closes open polylines, and fixes unit-conversion mismatches — in one pass.

What kind of DXF do I get back?

Clean, simple LINE-based geometry in optimized cutting order, designed for broad compatibility with CNC, laser, plasma, plotter, and waterjet controllers, including older and budget controllers.

Is it deterministic?

Yes. Processing uses fixed geometry rules, not AI, so the same input file always produces the same cleaned output.

Do I pay before I see the result?

No. The preview is always free — inspect the cleaned geometry and toolpath emulation before spending a token. Failed conversions never cost a token.
