		+	In most cases reciprocal lamella structures will be made up of elements which are twice the length of each grid unit, so that the next member is supported at the midpoint of the previous. This type of structure allows each member to be made up of relatively thin two dimensional linear beams or plates, in more complex structures these might be cut into certain shapes that interlink or slot together creating three dimensional structures or gridshells. A technique that expanded in popularity with the availability of CNC cutters or 2D routing in the 1970's and 80's.
