Which of the following is a 3D shape created from a 2D sketch using modeling features?

• A. Body
• B. Solid
• C. Shape
• D. Profile

Answer: (A)

A body is a 3D shape that is generated from a 2D sketch by utilizing various modeling features in CAD software. When you create a body, you begin with a 2D profile or sketch, which is then transformed into a three-dimensional object through operations such as extrusion, revolution, or lofting. This transformation enables designers to visualize and create complex geometries effectively, functioning as the foundational element in 3D modeling. Other choices such as solid and shape may refer to 3D objects but do not specifically denote the process of being derived from a 2D sketch. A profile typically describes just the 2D outline or contour before it is transformed into a 3D body. Thus, the term body signifies the completed 3D form that results from applying modeling operations on a 2D sketch.
