checkInnerWires: Checks what wires are inner ones by taking a set of prisms created with every wire.

The prisms are cut from each other. If the moment of inertia thereby changes, the prism wire is an inner wire. Inner wires can have nested inner wires that are then in fact outer wires. Therefore checkInnerWires is called recursively until all wires are checked.

◆ createTaperedPrismOffset()

void ExtrusionHelper::createTaperedPrismOffset	(	TopoDS_Wire	sourceWire,
		const gp_Vec &	translation,
		double	offset,
		bool	isSecond,
		TopoDS_Wire &	result
	)

static

createTaperedPrismOffset: creates an offset wire from the sourceWire in the specified translation.

isSecond determines if the wire is used for the 2nd extrusion direction.
