Square grips on a feature line can be moved in which direction(s)?

• A. In any (3 dimensional) direction
• B. Only along the line
• C. Only horizontally
• D. Only vertically

Answer: (A)

Grips on a feature line are 3D control points, and moving a square grip changes the vertex’s coordinates in all three dimensions. Because a feature line stores X, Y, and Z for each point, you can drag a grip in any direction—along the line, across plan view, or up and down to adjust elevation—and Civil 3D updates the coordinates accordingly. This 3D freedom lets you shape the feature line to match terrain or design targets in all directions, not just horizontally or vertically or only along the line.
