In printreading, what does a legend provide?

A legend is a vital component of printreading as it serves to provide explanations for the various symbols and abbreviations used in architectural and engineering drawings. It acts as a key that helps viewers understand the notations that may not be immediately clear, ensuring that the information presented in the drawings can be accurately interpreted. For instance, it might clarify what specific symbols represent different types of materials, fixtures, or processes depicted in the plans.

In contrast, while detailed measurements of the building, color codes for materials, and identifications of proposed structures are important aspects of construction documents, they are not the primary function of a legend. Measurements and structure identifications are typically found directly within the drawings, whereas color coding may be used to visually represent different materials but might not be explicitly broken down in a legend. Therefore, the legend's main purpose is to enhance understanding by clarifying the symbols and terms used in the drawings.
