The Post-Facto Explications diagram is a method of documenting and illustrating how various elements of a design relate to the overall building form after the design has been completed. It provides insights into the logic behind the final design choices.
This diagram is used to explain the relationships between different components and the thought process behind their integration into the final form of the building.
It does not focus on the sequence of steps or the sensory experiences during the design process, but rather the final arrangement and interrelationship of elements in the completed design.
