Final answer:
A Multi Sections Solid is the 3D feature that uses a reference plane and a curve to extrude a profile along a path, ideal for creating complex shapes in 3D modeling.
Step-by-step explanation:
The 3D feature that uses a reference plane and a curve to extrude a profile along a curve is known as a Multi Sections Solid. This feature is beneficial in creating complex shapes by sweeping a profile along a guide curve, which is defined by two or more section curves that the shape must pass through at specific locations along the guide curve. The other options, such as Drafted Filleted Pad, Rib, and Shaft, are different types of features that serve other specific purposes in 3D modeling software.
