If you want to just divide a surface with a sketch, you can use the Boolean fragments tool. But it gets trickier in most cases where you want to partition the face of a solid using planes in FreeCAD.

I’ve never used the Part Cross Sections tool for partitioning because it’s rather specific and inconvenient. But it creates wires in a similar way to an intersection with a sketch plane and those wires could be used to partition the faces of the object.

Or e.g.: Part Cross sections → Draft Upgrade (create faces) → Part Union → Part Slice apart

There are many options for such cuts in FreeCAD, and they are all good as long as they create valid solids and the division into parts or faces is as required in the STEP file imported to PrePoMax.
