[Closed] UVW get elements from face selection

Hi

Is there any fastest way to collect elements from face selection in Unwrap Modifier?
And store area info.

	fn getElements mod_uvw faces_array =
	(
		struct ELEMENTS (faces=#{}, area=0)
		local el = #()
		while faces_array.count != 0 do 
		(
			local next_face = faces_array[1]
			mod_uvw.selectFaces #{next_face}
			mod_uvw.selectElement()
			local el_faces = mod_uvw.getSelectedFaces()
			local areaUVW
		mod_uvw.getArea el_faces &x &y &width &height &areaUVW &areaGeom 
			el += #(ELEMENTS el_faces areaUVW) 
                                 --remove faces from array
			faces_array = (faces_array as bitarray - el_faces) as array 

		)
		return el
	)

any suggestion will be appreciated
