Warning: Spent 2 years drawing details on layer 0 before a senior drafter spotted it
I was about 6 months into my first drafting job at a small firm in Columbus. Every project, I'd just throw everything onto layer 0 because it was the default and I figured I'd sort it later. Never caused big issues until we had a client revision on a commercial HVAC plan. Senior drafter, Mike, needed to isolate the ductwork and everything stayed visible. He spent 20 minutes looking at my file, then just pointed at the screen and said "you know everything's on layer 0, right?" Had to redo the whole set from scratch. Felt like an idiot. Has anyone else had a habit that took way too long to break?
