Back when every boiler layout started with a pencil and paper

I learned to draft boiler plans by hand on huge rolls of paper when I first started. We used pencils and erasers, and every change meant redrawing whole sections. One time, a hand-sketched support bracket was off by an inch, and we had to cut and reweld on the spot. Now, with CAD software, we model everything in 3D and catch mistakes early. It's way faster and more precise, but I do miss the quiet focus of drawing by hand. My advice is to keep a tape measure handy even with digital plans, because real-world fits can surprise you. The tools evolve, but the need for careful work never goes away.

Saying it's an exaggeration shows you haven't had to fix a hand-drawn error on site. I've been there, and one small mistake in a sketch meant hours of rework. That's why I always double-check measurements with a physical tape, even with CAD models. Digital plans can lie about clearances, so you need to check in the real world. The quiet focus of drawing by hand is nice, but catching errors early saves so much trouble. Why risk a field fix when you can check it twice?

Mostly redraw whole sections? That's an exaggeration.

Have you ever seen one tiny mistake make you redo a whole drawing? It's not an exaggeration at all, especially with hand-drawn plans! A single wrong line can mess up everything that follows. That's why checking twice with a tape measure is so important, like jenny said. A little extra care early on stops big headaches later!
