Loft features blend multiple profiles, called sections, and transition them into smooth shapes between profiles or part faces. The sections can be curves in 2D sketches or 3D sketches, model edges, or face loops. You can use rails, or a centerline and point mapping, to control the shape and prevent twisting. For open lofts, one or both end sections can be a sharp or tangent point. Loft can produce both solids or surface bodies.
