Vent: spent 4 hours redoing a roof line because I didn't check my scale first
I was working on this residential house over in Oakville last Thursday, drafting up the roof trusses for a new addition. Everything looked good on screen, angles were matching, loads seemed right, but when I printed my shop drawing and walked it over to the framing crew, the foreman just stared at me. He pointed out that my pitch was off by like 2 degrees because I had scaled the whole thing from a site photo without double checking the actual rise and run on site. So I had to go back, grab my tape, measure everything myself, and redo the whole thing from scratch. It was a brutal afternoon hunched over the board trying to fix my own mistake while the crew waited. Has anyone else gotten burned by trusting a photo scale over real measurements?
