What type of drawings are used to showcase the vertical and horizontal sections of a building?

The correct answer focuses on cross-sections as they specifically represent vertical slices through a building, illustrating interior spaces, structural elements, and the arrangement of various components at different heights. This type of drawing allows one to visualize how different levels of a structure connect and the relationships between various rooms or areas, providing clarity on the vertical alignment and dimensions.

Cross-sections serve a unique purpose distinct from other types of architectural drawings. For example, floor plans offer a horizontal overview of a building's layout at a given level but do not convey vertical relationships. Elevation drawings depict the exterior facades of a building from various angles, concentrating on height and appearance rather than internal configuration. Detail drawings focus on specific architectural elements, providing more precise information but not the overall spatial arrangement. Hence, cross-sections stand out for their ability to clearly represent both vertical and horizontal aspects concurrently.
