NCIDQ Interior Design Professional Exam (IDPX) Practice Exam

A detail drawing is the most suitable choice for clarifying the finish transition from a poured concrete floor to a thin-set porcelain tile. Detail drawings provide a specific and precise representation of how different materials and finishes come together at junctions or transitions. They often include dimensions, material specifications, and installation techniques, making them invaluable for contractors and installers during construction.

In the context of a finish transition, a detail drawing can illustrate the exact edge treatment, height differences, and any necessary shimming or leveling methods required to properly install the porcelain tile adjacent to the concrete floor. This level of detail ensures that the finished product meets design intentions and functional requirements, such as water drainage and aesthetic continuity.

Other drawing types, while useful for different aspects of a project, do not provide the same level of specificity regarding junctions or material transitions. For example, a finish schedule lists finishes throughout the project but does not depict how they relate to one another spatially. A section drawing shows a slice through a space but may not detail the specific connection between differing surface materials. An elevation drawing depicts the vertical aspects of a space but doesn't convey depths or transitions clearly. Therefore, the detail drawing's focused nature makes it the best choice for this particular requirement.
