Which vertex type is abbreviated as CV and is not constrained to lie on a surface with adjustable influence weight?

• A. Surface point
• B. Control Vertex
• C. Normal
• D. EM Face

Answer: (B)

In spline modeling, how a vertex behaves determines how you shape the geometry. The Control Vertex, abbreviated as CV, is the point you edit to define the spline’s form. It is not tied to any surface, so you can move it freely in 3D space and it carries an adjustable weight that changes how strongly that point pulls on the curve as you edit it. This free, weight-influenced control is what makes a CV the best fit for representing the option described. By contrast, a surface point must lie on the underlying surface, which constrains its position, and other terms like normal refer to directionality rather than a movable vertex type, while EM Face refers to polygonal faces in mesh editing rather than a vertex type used to shape curves.
