Which statement best describes a spline?

• A. A viewport display setting that shows objects as a wire mesh.
• B. A collection of vertices and connecting segments that form a line or curve.
• C. Contains information about the scene and the active command.
• D. A subset of an object's geometry.

Answer: (B)

In 3D modeling, a spline is a curve defined by points connected by a sequence of segments, forming a continuous line or smooth curve. This means it consists of a collection of vertices and the connecting segments that link them, allowing you to shape the curve by moving those points and adjusting the segments. Splines are foundational for creating outlines, paths, and shapes that can later be turned into surfaces or extruded, beveled, or swept along a path. The other statements describe unrelated concepts: a viewport display setting is about how objects are drawn on screen, information about the scene and active command relates to UI/state data, and a subset of an object's geometry refers to subobjects or partial geometry, not the curve itself.
