The two-dimensional structures are expanded into the third dimension, creating a three-dimensional line grid which serves as the base for the structures and surfaces. The three-dimensional movement and shape of the structures are defined by overlapping the already 3D vertical and horizontal line systems.

The three-dimensional surface study is a significant development of the two-dimensional structure study. The two-dimensional grid systems and structure bases are transformed into three-dimensional drawings.
