The shape to slice: faces come from its solids, wires from its solids, shells and faces.
One plane per frame, through the frame's origin and square to its normal; the frame's direction does not matter.
OptionalmakeWhen true, each slice holds the faces where its plane passes through the solids, holes included; when false, it holds the section wires.
OptionaltoleranceHow close the ends of two section edges must lie to be joined into one wire, in model units.
A shape, the frames whose planes slice it and what each slice keeps for
operations.sliceByFrames, which gives one slice per frame.
