Which element is defined as the portion of a spline between two vertices?

• A. Vertex
• B. Segment
• C. ViewCube
• D. Viewport

Answer: (B)

Think of a spline as a chain of curved pieces. Each piece runs from one vertex to the next, and that piece is called a segment. The vertex is just the endpoint that defines where the segment starts or ends, not the actual curve portion itself. UI tools like the ViewCube and the Viewport aren’t part of the spline’s geometry. So the portion of the spline between two vertices is a segment. In a spline with N vertices, there are N-1 segments, and the shape of each segment is influenced by the tangents or handles at its endpoints.
