Which of the following is a linear object that has been defined using survey data?

• A. Survey Figure
• B. Profiles
• C. Contours
• D. Surface

Answer: (A)

In Civil 3D, a linear object defined using survey data is a survey figure. A survey figure is created directly from field measurements, connecting survey points with segments to form a linear representation of a surveyed feature such as a road or boundary. This makes it a true linear element built from survey data. Profiles are elevation-versus-distance representations along an alignment, not standalone linear features defined by survey data. Contours are lines of equal elevation on a surface, and a surface is a 3D representation of the terrain, not a single linear object. So the survey figure is the correct choice because it embodies a linear element defined from the survey data.
