Which of the following is not a way of displaying a structure?

• A. Outline icon
• B. Elevation marker
• C. 3D model
• D. COGO point

Answer: (D)

Displaying a structure involves visual representations that show its footprint, height, and shape in plan and 3D views. An outline icon gives a 2D footprint indication on a plan, an elevation marker shows the vertical position or height relative to a reference surface, and a 3D model presents the full geometry in three dimensions for visualization and analysis. A COGO point is a survey data point that stores coordinates for staking or design references; it does not render or visualize the structure itself. So, a COGO point is not a way to display a structure.
