Which item represents a curve formed by control points?

• A. Move, Scale, and Rotate
• B. Box
• C. The G Key
• D. Spline

Answer: (D)

Splines are curves built from control points. Each control point (or vertex) influences the shape of the curve, and moving these points lets you sculpt the curve’s form with precise bumps, tangents, and smooth transitions. In 3DS Max, you work with a spline by creating a spline object and then editing its control points to define the desired curve. The other options don’t describe a curve: Move, Scale, and Rotate are transformation tools; Box is a box primitive; and the G key simply toggles grid visibility. So the item that represents a curve formed by control points is the spline.
