To determine which element of art is most evident in the drawing of buildings, we would typically consider aspects such as line, shape, form, space, color, value, and texture.
In architectural drawings, line is often the most prominent element, as it defines the structure, outlines, and details of the buildings. Shape and form also play significant roles in conveying the three-dimensional aspects of the buildings.
If you have a specific drawing in mind, you could analyze it by looking closely at these elements to identify which one stands out the most. If you provide more context or details about the drawing, I can help you pinpoint the dominant element of art.
