Which term is used to describe a curved transition between two surfaces?

• A. Fillet
• B. Inscribe
• C. Spline
• D. Revolve

Answer: (A)

A fillet is the curved transition where two surfaces meet. It creates a smooth, rounded corner instead of a sharp edge, helping to distribute stresses more evenly, improve manufacturability, and can influence the part’s appearance. The curvature is defined by a radius, which controls how pronounced the bend is. A spline is a flexible curve used to define shapes, but it’s not specifically a junction between surfaces. Inscribe refers to fitting one shape inside another boundary, and revolve means creating a solid by rotating a profile around an axis. So the curved transition between surfaces is a fillet.
