Transform real objects into true-scale outlines.
Quick tips
- Print our A4 distortion-correction Markers and keep it visible. ShapeScan uses it to correct lens warp and rectify robustly.
- Using US Letter? Print the US Letter distortion-correction Markers instead.
- Keep the sheet flat (clipboard/glass) and use soft, diffused light.
- Works without the Markers, but detection is less robust.
What Makers & Engineers Scan with ShapeScan
Laser Cutting Templates
Digitize hand‑drawn designs, existing parts, or organic shapes into cut‑ready DXF files. Perfect for acrylic, wood, leather fabrication.
CNC & Router Workholding
Create custom foam inserts, tool holders, or vacuum fixtures by scanning physical objects directly. Export to DXF for CAD software.
3D Modeling Reference
Convert real‑world objects into scale‑accurate SVG/STL for Fusion 360, SolidWorks, or Blender reference. Perfect for reverse engineering.
Gridfinity & Organization
Scan tools, electronics, or kitchen items to design perfect‑fit organizers for 3D printing. Create custom Gridfinity bases in minutes.
How ShapeScan Creates True-Scale Outlines
1
Marker‑Based Calibration
Four ArUco corners establish scale and correct perspective. For the cleanest geometry, use the phone's normal lens and keep the camera parallel to the sheet.
2
AI‑Assisted Segmentation
BiRefNet-assisted segmentation separates the object from the sheet. Difficult shadows, reflections or transparent materials may still need a better photo or editor refinement.
3
Edge‑Snap Refinement
Contour points can snap to visible edges, and the built-in editor lets you inspect and refine the result before manufacturing.
4
Multi‑Format Export
Export SVG, Fusion SVG, DXF, PNG, STL or STEP. Always verify critical dimensions, tolerances and fit before cutting or printing.

Frequently Asked Questions
What accuracy can I expect from ShapeScan?
With a flat, correctly printed marker sheet and a sharp photo, ±1 mm is a typical target. Results vary with capture quality, material, scale, machine calibration and kerf, so verify critical dimensions before manufacturing.
Do I need special equipment or a good camera?
No special rig is required. A modern smartphone, a correctly printed marker sheet and soft light are enough. Use the normal lens, keep the full sheet visible and avoid blur or strong perspective.
Can I scan objects with holes or cutouts?
Yes. Enable "Keep internal holes" in advanced settings. ShapeScan will detect openings like scissors handles, wrench holes, or decorative cutouts and preserve them as separate paths in the SVG/DXF. The editor also lets you manually add or remove holes.
What's the difference between SVG and DXF output?
SVG is best for laser cutters, vinyl cutters, and web use. DXF is the industry standard for CAD software (Fusion 360, AutoCAD, SolidWorks). ShapeScan generates both with identical geometry. For CNC machining, use DXF. For laser cutters, SVG often works directly.
Is my data private? Where are photos processed?
Processing happens on ShapeScan's servers. Anonymous jobs are temporary; account jobs can remain saved up to the limit of the selected plan. We do not sell uploaded images. See our Privacy Policy for retention and service-provider details.
Can I use ShapeScan for commercial projects?
Yes. Files you generate may be used in personal and commercial projects, subject to the Terms of Service. Free use has queue, batch and storage limits; optional Premium plans add capacity and priority processing.
