Photo · Sketch · Scan → DXF

Turn drawings into editable CAD.

Drop in a part photo, hand sketch, or scanned drawing and get native line, arc, and circle entities you can open in AutoCAD, Fusion 360, or LibreCAD. Correct perspective, calibrate real dimensions, and export DXF or SVG — preview is free, everything runs on your device.

Why CAD Trace

A raster image becomes a CAD drawing.

Not a picture embedded in a DXF — actual editable geometry with layers, scale, and clean endpoints.

Native line, arc, circle entities

A purpose-built contour engine traces the linework, then fits straight lines, arcs, and full circles with endpoint snapping and corner detection. Freeform remnants stay as polylines.

Calibrated real-world dimensions

Click any edge, type its real length in mm, cm, m, or inches, and every entity, measurement, and exported coordinate is scaled accordingly — the DXF lands in your units.

Four-point perspective correction

Shot a drawing at an angle? Drag four corners onto the sheet and the keystone is rectified before tracing, so sides come out horizontal and vertical.

Preview free, export when ready

Trace, tune, and inspect as many drawings as you like at no cost. A DXF/SVG export costs one of three monthly free credits — Pro is unlimited. No uploads, ever.

How it works

From paper or photo to CAD in three steps.

  1. 01

    Add the drawing

    Drag in a part photo, a phone picture of a whiteboard sketch, or a scanned plan. Pick the matching mode: sketch, scan, or photo.

  2. 02

    Trace and tune

    Linework is binarized, contoured, and fitted into CAD entities locally. Optionally fix perspective, then adjust simplification and arc recognition live.

  3. 03

    Calibrate and export

    Set one known dimension for true scale, toggle layers, then download DXF (R12/AC1009) for CAD software or SVG for vector apps.

FAQ

Answers about CAD Trace

A DXF in the R12 (AC1009) format, which opens in AutoCAD, Fusion 360, LibreCAD, Inkscape, and virtually every CAD package, plus an SVG for Illustrator, Figma, and the web. Entities are real LINE, ARC, CIRCLE, and POLYLINE records on three layers — not a traced bitmap.
