Guide: Free Alternatives to Scan2CAD

1. Understanding the Core Task

Scan2CAD specializes in raster-to-vector conversion (vectorization).
A free alternative must handle:

How to do it (Free):

  1. Download Inkscape (Free, Windows/Mac/Linux).
  2. Import your raster image (JPEG or PNG).
  3. Select the image, navigate to Path > Trace Bitmap.
  4. Switch the mode from Brightness to Autotrace.
  5. Use the "Centerline Tracing" option. This is critical. Scan2CAD excels at centerline tracing (reducing thick lines to single strokes). Most free tools only do edge tracing (outlining both sides of a line, creating double lines).
  1. Load your raster map image into QGIS.
  2. Use the "Georeferencer" tool to assign coordinates to the image.
  3. Use the "Digitizing" tools to trace over the raster lines, creating vector shapefiles or DXF outputs.

Limitations in the free version: The "Pro" features (advanced batch conversion, HPGL import) are locked, but the community version handles single-image conversions well.

3.7 OCR/Text extraction: Tesseract + manual anchoring
