Here is a quite short description: https://github.com/chbergmann/CurvedShapesWorkbench#-surface-cut Maybe the CrossSections function in the Part workbench is a better alternative for you. See https://wiki.freecad.org/Part_CrossSections I wrote the SurfaceCut because the CrossSections function cannot be used easily in Python scripts.
