Orthographic projections-that is, plans and sections-are one of the most valuable representational tools architects have at their disposal. They are an indispensable communication and design device. They have also contributed to a prominent digital fabrication method. With computer modeling, deriving sections is no longer a necessarily two-dimensional drawing exercise. In fact, it is no longer an exercise in projection at all but a process of taking cuts through a formed three-dimensional object. As architects increasingly design with complex geometries, using sectioning as a method of taking numerous cross sections through a form has proven time and again an effective and.
