Which of the following is a primary advantage of using a markup legend?

• A. Changes the measurement units
• B. Shows a key to the symbology of your markups
• C. Exports markups to CSV
• D. Automatically saves all markups to the cloud

Answer: (B)

A markup legend is a centralized reference that defines what every symbol, color, and label in your markup means. Its primary advantage is that it shows a key to the symbology of your markups, so anyone reviewing the document immediately understands what each mark represents. This clarity helps all stakeholders interpret measurements, comments, and proposed changes consistently, reducing confusion and back-and-forth.

Having a legend also supports project-wide standards: you can customize it to reflect your company’s symbols and color codes, making it easy to reuse across multiple sheets and drawings. While the legend itself doesn’t change measurement units, export markups to CSV, or auto-save to the cloud, those tasks are separate features—handled by the measurement tools, export functions, and the app’s save behavior.
