The term 'criss-cross framework' refers to a structure composed of intersecting lines, often forming a LATTICE or GRID. A LATTICE is a structure made up of crossed strips of material, such as wood or metal, that form a regular pattern of squares or diamonds. A GRID is a network of lines that cross each other to form a series of squares or rectangles. Both lattices and grids are used in architecture, engineering, and other fields to provide support and structure.
