That week I had to redo a whole set of foundation plans because of a single wrong layer setting
It was a rough few days, let me tell you. I was finishing a set of residential plans for a client in Phoenix, and I sent the PDFs over for review. They came back with a question about a footing detail that looked totally off. Turns out, I had a custom layer for 'existing grade' that was set to not plot, but it was still visible on my screen. I based all my new foundation elevations on that hidden line without realizing it. Had to go back through about 15 sheets, checking every spot elevation and dimension against the survey file. What made it worse was the deadline was tight, so I pulled two late nights in a row to fix it. The lesson was painfully simple: always do a full PDF plot review yourself before sending anything out, even if you're sure it's right. Has anyone else had a layer setting ghost them like that?
