Which design phase progresses from diagrams to more detailed drawings?

The correct choice pertains to the Schematic Design phase, which is the initial stage in the design process. This phase focuses on the overall layout and general components of the project, represented through diagrams and basic sketches. As the project moves through this stage, designers begin to refine ideas by creating more detailed representations, which involve various factors such as dimensions, materials, and spatial relationships.

During this transitional period from schematic plans to actual drawings, the design team works on visualizing the project more precisely, incorporating feedback and adjustments to ensure it aligns with the project's goals and requirements.

By comparison, the Design Development phase follows Schematic Design and is where much of the detailed work occurs, transforming the broader concepts into more technical and comprehensive drawings, ensuring that the designs can be realized in construction. Pre-Construction is focused on planning the construction logistics, and Close-Out involves finalizing project details after completion. Thus, Schematic Design is distinctly characterized by its progression from conceptual diagrams to more detailed drawings, making it the right answer.
