The essential idea here is understanding which drawing is used to guide putting the building together on site. An assembly drawing is the one that provides instructions for erection and shows how the building parts fit as a whole. It often includes how components connect, the order or sequence of assembly, fastening details, and critical clearances so the structure goes up correctly. Framing drawings focus on the structural members themselves—sizes, types, and connections—but not the step-by-step erection process. Floor plans show the layout of spaces and walls, not how to assemble the building. A reflected ceiling plan documents ceiling elements like lights and ducts as seen from above, not how to erect the structure. So the drawing that best communicates erection instructions and how to assemble is the assembly drawing.
