For Paul Lewis, Marc Tsurumaki and David J. Lewis, the section ?is often understood as a reductive drawing type, produced at the end of the design process to depict structural and material conditions in service of the construction contract.? A definition that will be familiar to most of those who have studied or worked in architecture at some point. We often think primarily of the plan, for it allows us to embrace the programmatic expectations of a project and provide a summary of the various functions required. In the modern age, digital modelling software programs offer ever more possibilities when it comes to creating complex three dimensional objects, making the section even more of an afterthought.
