 Loftsmen at the mould lofts of shipyards were responsible for taking the dimensions and details from drawings and plans, and translating this information into templates, battens, ordinates, cutting sketches, profiles, margins and other data.From the early 1970s onward computer-aided design (CAD) became normal for the shipbuilding design and lofting process.Lofting was also commonly used in aircraft design before the widespread adoption of computer-generated shaping programs.
