Frequently Asked Questions

Technically, you could ask an AI to analyze a DXF file, but it wouldn't produce reliable results. AI models work with probabilities, not exact geometry. They can't guarantee that every duplicate was found, that coordinates weren't shifted, or that the output is identical across runs. For a file that will drive a laser cutter or appear on a building permit, that level of uncertainty is unacceptable. Razoar uses deterministic algorithms that guarantee the same input always produces the same output. Read our full comparison.

Razoar offers 3 free cleanings to get started, no credit card required. It handles duplicate removal, micro-segment cleanup, collinear merging, and overlap detection — all running in your browser with no installation. For higher volumes, credit packs start at CHF 9.90 and Pro plans start at CHF 14.90/month.

Upload your DXF to Razoar, adjust the duplicate tolerance slider (the default works for most files), and export the cleaned file. Razoar finds exact duplicates, reversed duplicates, and near-duplicates within your chosen tolerance — instantly, with a real-time preview showing which segments will be removed.

Yes. Razoar reads standard DXF files regardless of which CAD software created them. It handles LINE, LWPOLYLINE, ARC, CIRCLE, and SPLINE entities. Files exported from AutoCAD, LibreCAD, FreeCAD, Revit, SolidWorks, and other tools all work.

No. Razoar runs entirely in your browser. Your DXF file never leaves your device — there's no upload, no cloud processing, and no data retention. This makes it safe for confidential architectural plans, proprietary industrial designs, and any file you wouldn't want on a third-party server.

Razoar fixes four common DXF problems: duplicate segments (exact, reversed, and near-duplicates), micro-segments (lines too short to be meaningful), collinear segments (touching lines on the same axis that should be merged), and overlapping segments (shorter lines fully contained within longer ones). You can enable or disable each operation independently and adjust tolerances with sliders.

Razoar cleans a 178,000-segment architectural plan in about 3 seconds. It runs directly in your browser using high-performance compiled code, so there's no server round-trip. Smaller files (under 10,000 segments) are cleaned in under a second.

No. Razoar never modifies your original file. It produces a new cleaned DXF that you download separately. Non-LINE entities (circles, arcs, text, dimensions) are preserved exactly as-is in the exported file.
