AS4CAD was coded based on the AS4QGIS.model3. While the AS4CAD.lisp is the product of an LLM, AS4QGIS was built from scratch through meticulous manual work in the QGIS Model Designer.

Within a QGIS environment, AS4QGIS generates essentially the same final results as AS4CAD from identical input.

If you wish to generate and edit your spatial data within a GIS environment, AS4QGIS might be the right choice for you.
