The example block was copy pasted verbatim from ExtractPropertiesToSQLite, so it named the wrong recipe and wrote a .sqlite file. These docstrings are what ifcpatch surfaces as CLI and UI help, so anyone following the example for AGS2IFC got a recipe name that does not match the one they selected. Also state that the input file is not read and that a new IFC4X3 model is built, since that is not obvious from the signature and the recipe creates its own project rather than patching the one passed in. Generated with the assistance of an AI coding tool.
IfcPatch
Utility for applying modification recipes to IFC files. IfcPatch enables programmatic editing and correction of IFC models through a collection of patches that can fix common issues, migrate data, or transform models.
