8. Conclusion
   Free alternatives can reproduce much of Scan2CAD's functionality for moderate workloads with acceptable accuracy when combined into workflows using Inkscape, Potrace/Autotrace, OpenCV scripting, and DXF editors like LibreCAD. Choose a manual Inkscape-focused flow for occasional conversions; build an OpenCV+ezdxf pipeline for batch/complex tasks. Consider commercial options when automation, high accuracy, and advanced OCR/layering are essential.
