Sometimes yes; sometimes no. Not every logo design needs, or even benefits from a structured logo design grid, let alone a complex pattern of interweaving circles, lines and guides. However, when a logo design needs such structure, or it at least helps me create a sense of balance, then I will create a grid with circles, guides and other intersecting elements.
