What feature could be used to create a 3D representation of a baseball bat that was created on a wood lathe?

• A. Loft
• B. Revolve
• C. Sweep
• D. Fillet

Answer: (B)

Creating a 3D representation of a lathe-turned baseball bat is best done by revolving a 2D profile around a central axis. The bat is basically rotationally symmetric along its length, so sketching its profile (outlining how the diameter changes from handle to barrel) and spinning it around the axis produces the solid shape accurately. This mirrors the turning process where the wood is spun and shaped to form the smooth, rounded form. The other tools don’t fit as cleanly: loft would blend different profiles along the length, which isn’t necessary for a uniform, symmetric bat; sweep follows a path to create a shape along that path, better for curved, non-rotational forms; fillet only rounds edges and wouldn’t generate the overall bat geometry.
