Which term describes a curved or straight line defined by connected vertices?

• A. Wireframe
• B. Segment
• C. Spline
• D. Workflow

Answer: (C)

A spline is the line type that describes a curved or straight path defined by connected vertices. In 3D modeling, you place a sequence of control points (vertices), and the software interpolates a smooth curve that follows those points, producing a continuous line that can bend smoothly. If the points line up, the spline behaves like a straight segment; if they’re offset, the curve smoothly bends between them. This makes splines the go-to concept for creating paths, outlines, and curved geometry. A wireframe is simply the display of a mesh’s edges, not a single line defined by connected points. A segment is just one straight piece between two points, not the full connected path. A workflow is unrelated to the geometric concept.
