What is lofting definition?

Lofting is a process in shipbuilding and boatbuilding where plans, drawings, or computer-aided design (CAD) models of a vessel are scaled up and transferred to a full-sized work surface using measurements and calculations. This work surface, typically a large table or floor, is known as the loft floor. The lofting process involves laying out and marking the various frame lines, sections, and other details of a ship's hull and superstructure onto the loft floor using precision measuring tools such as a tape measure, dividers, plumb lines, and straightedges.

Lofting is an essential step in shipbuilding as it allows shipbuilders to visualize and fine-tune the design of a vessel prior to construction, ensuring that all the components and dimensions are accurately planned and laid out. It also helps to minimize errors and reduce waste during construction, as builders can refer to the loft floor throughout the building process to ensure that the final product matches the original plans. Lofting is still used extensively in traditional shipbuilding, but has been largely replaced by digital design software in modern shipyards.
