Reveals are recessed or projecting features in a wall, often used with moldings to create depth and shadow lines. To convey the depth and profile of reveals, a vertical section is the best type of detail because it shows a cross-sectional view of the wall, illustrating the reveal’s depth, shape, and relationship to the moldings in a vertical plane. This provides contractors with the necessary information to construct the wall accurately. Option A (plan detail) shows a top-down view, which doesn’t convey depth. Option C (elevation detail) shows the wall’s appearance but not the internal profile or depth. Option D (horizontal section) shows a horizontal cut, which is less relevant for vertical features like reveals.
