What defines a detailed plan of a building drawn orthographically?

The correct answer highlights that a "print" refers to a detailed plan of a building drawn orthographically. In architectural drawing and construction, orthographic projection is a method where three-dimensional objects are represented in two dimensions. This technique allows for different views of the building, such as the floor plan, elevation, and sections, displayed on a single sheet.

A print specifically denotes a graphical representation that conveys the dimensions, layout, and relationships between different elements of the building, providing precise information for construction. This level of detail is essential for contractors and builders to accurately interpret the design and execute it on site.

In contrast, while a blueprint also refers to a detailed plan and often serves the same function, it traditionally refers to a specific process of printing plans that results in white lines on a blue background. This historically significant method has largely been replaced by digital processes, making "print" a more appropriate and encompassing term for representing design documents regardless of the printing method used.

Other options like a diagram generally serve a more illustrative purpose and may not provide the depth of detail required for construction, while a model refers to a physical three-dimensional representation of the building and does not convey the specific dimensions and details in an orthographic format.
