A 3D shape with one edge is known as a "curved surface" or more specifically, a "cylinder" with its top and bottom bases removed, resulting in a shape resembling a "circular loop" or "moebius strip." However, in strict geometric terms, conventional polyhedra cannot exist with just one edge. The concept of a 3D shape having only one edge typically refers to more abstract or non-Euclidean geometries.

An ellipsoid with a slice removed.
The edge of a 3D shape is called an "edge." It is the line segment where two faces of the shape meet. In geometric terms, an edge is one of the fundamental components that define the structure of polyhedra and other solid figures.

An edge.
A cone, a sliced ellipsoid (including sphere) are two possibilities. There are others.
