section drawing
At any point on the plan of a building, the architect can describe a line through the drawing and represent a vertical cut through of the spaces. This representation drawing is called a section and it explains the volumes of the spaces and indicates the position of the walls, floors, roof and other structural elements. This type of drawing also allows the architect or designer to investigate such issues as the exploration of the structure, the admission of light, vertical interaction within the building and relationships between the interior and exterior.
