Which of the following best describes a rough sketch in architectural design?

A rough sketch in architectural design is best described as an initial outline used to explore ideas. This type of sketch serves as a preliminary step in the design process, allowing architects and designers to quickly visualize concepts, experiment with layouts, and communicate ideas without the constraints of precision. Rough sketches are typically informal and can be fluid, which encourages creativity and exploration during the early stages of design development. They focus on capturing the essence of a project rather than detailing every element or dimension, making them an essential tool for brainstorming and refining design intentions before progressing to more detailed and finalized drawings.
