We are accustomed to viewing architecture in two successive stages, planning and execution, which define the domain of two separate professions, architects and builders. The communication of visual ideas between these two parties relies on and is carried out through the medium of architectural drawing, which not only allows for a projection of imagined buildings but also provides the principal device for creating architectural forms. As described by professionals, the reconciliation of the two three-dimensional variable components-interior and exterior-depends on continuous mutual assessment through the medium of an architectural drawing.
