DXF viewer online — open drawings with layers & measure, no upload

• Opens ASCII DXF from AutoCAD, LibreCAD, QCAD, Fusion 360, SolidWorks and laser/CNC tools — lines, polylines with bulges, circles, arcs, ellipses, splines, text, blocks and dimensions.
• Layer panel with the drawing’s own colours: show or hide any layer, and hidden layers stay out of the SVG export too.
• Measure with endpoint snapping — click two points for the distance with X/Y deltas, in the drawing’s units or your override (mm, cm, m, inch).
• Crisp Canvas rendering with zoom-at-cursor, pan, pinch and double-click-to-fit; white “paper” or dark background, whichever reads better.
• Export a PNG snapshot or a true-scale millimetre SVG that opens in LightBurn, Illustrator or Inkscape.
• 100% in your browser — drawings are parsed locally in a background thread, never uploaded. No account, no watermark.

1. Drop the DXFDrag a .dxf file onto the viewer. Parsing runs in a background thread, so even large drawings keep the page responsive — and nothing is uploaded.
2. Browse layersToggle layers, switch paper/dark background, zoom to the details. The extents and entity counts appear in the panel.
3. Measure & exportSwitch to Measure and click two points — snapping lands on exact endpoints. Then export a PNG or a true-scale SVG.

DXF is the drawing exchange format every CAD, laser and CNC tool speaks — but opening one usually meant installing a viewer or uploading the drawing to someone’s server. Drop the file here instead: it is parsed in your browser, layers keep their colours, blocks and dimensions render, and you can measure a part or check a clearance before replying to a supplier. Sensitive fabrication drawings never leave your machine, which is the whole point.

DWG is AutoCAD’s closed binary format; DXF is its documented exchange twin. This viewer reads ASCII DXF (R12 through 2018) — if you have a DWG, use your CAD tool’s “save as DXF” once and every browser tool can read it forever. Geometry covered: lines, polylines (including arc bulges), circles, arcs, ellipses, splines, hatches’ boundary lines, text and MTEXT, blocks/inserts and pre-rendered dimensions. Paper-space layouts and a few exotic entities are skipped and reported, never silently.

• ASCII DXF only — DWG and binary DXF are closed formats; export ASCII DXF from your CAD tool first.
• Hatch fills, paper-space layouts and OLE objects are not rendered; skipped entities are counted and listed, never dropped silently.
• Text uses a standard sans font, so exotic SHX font spacing can differ slightly from AutoCAD.
• Measurements are between clicked points (with endpoint snapping) — angular and radial dimensioning tools are not included yet.
