Which term describes a grading object used to fill a void within a grading group?

• A. Delta
• B. Infill
• C. Compass
• D. Pad

Answer: (B)

In Civil 3D grading, a grading group defines an area using various grading objects, and any empty space within that area needs something to define its surface. The object used to fill that gap is called an infill. It serves as a filler so the surface has continuous elevation data, which is essential for accurate surface modeling and volume calculations. The other terms don’t describe a filler for a void: delta isn’t a standard grading object type in this context, compass is unrelated, and a pad is a flat area object but not the designated filler for a void within a grading group.
