Old timer at the union hall changed how I read a blueprint

I was killing time before a shift in Gary last Tuesday when this retired boilermaker named Walt pointed at my layout sheet and said I was chasing dimensions instead of the weld joint itself. He showed me how he marks the sequence on the drawing before touching steel, working the fit-up order backward from the hardest access point. It sounds simple but after 14 years I'd never thought of it that way, and it saved me about 3 hours on a feedwater tank mockup. Anyone else got a veteran trick that flipped their process upside down?

There was a thread on the weldingweb forum years back where an old pipe fitter said pretty much the same thing. He called it reading the part instead of the print. His whole point was that the drawing tells you what the thing looks like when it's done, but it doesn't tell you how to get there, and that's the part that actually costs you hours. He said he always starts with the joint he can barely reach or see, then builds out from that, because if you save the worst one for last you end up tearing stuff apart. I tried it on a small skid job after reading that and it felt backwards the whole time right up until it didn't. Never went back to the old way after that.
