"After my clearance was granted, I moved into the main drafting room with about sixty other draftsmen, designers, and lofts men. (A loftsman develops full scale patterns, or drawings, of complex shapes.)"
What does "develop full scale patterns, or drawings, of complex shapes" mean in the context that this is different from drawing blueprints like the draftsmen?
- inetsee 7y agoI believe loftsmen prepare full size drawings or patterns at 1 to 1 scale, whereas a blueprint may be at a reduced scale. I.e. a blueprint fits on a drafting table; the pattern created by a loftsman would go on a factory floor.
