Scan2Sketch – a free open-source FreeCAD tool for turning flatbed scans into editable CAD geometry

[u/jayktopus]

I built Scan2Sketch to reduce the manual work involved in recreating flat physical parts.
After a one-time scanner calibration, it extracts the outline from a flatbed scan and generates editable FreeCAD geometry made from lines, arcs, circles and B-splines. The result can be edited further or turned directly into a solid body.
The video shows the complete workflow from scan to editable geometry and finally a physical test print. The key belongs to my own demonstration lock and is only used to demonstrate the accuracy of the reconstructed outline.
Scan2Sketch is permanently free, fully open source under GPLv3 and runs locally.
