Every pipe you've ever walked past, behind a wall, under a street, running the length of a plant ceiling, existed first as a drawing. Someone understood exactly what needed to connect to what, and turned an engineer's intent into instructions precise enough to build from. That person is a pipe drafter. If you're reading this, there's a good chance that role already sits somewhere in your future. Maybe it's a CAD job posting that keeps saying "piping experience preferred," and you're not sure how you'd ever get there. Maybe you're a junior CAD operator who was handed piping work last month with no real training, quietly falling behind while hoping it doesn't show. Maybe you're a student whose program explains the software but skips the fundamentals that actually get someone hired. Wherever you're starting from, the distance between where you are now and a confident, employable understanding of piping design is smaller than it feels. It's a sequence: read a drawing before you draw one, understand fittings before flanges, plans before isometrics. This book lays out that exact sequence, in the same order a new hire encounters it on the job, with a diagram on nearly every page and a hands-on exercise closing every chapter. What it won't do is let the fundamentals stay theoretical. By the last chapter, you're not just able to name a valve symbol; you can read a real piping arrangement, build a complete isometric, and produce a bill of materials from it: the same core skills expected on day one of an entry-level role. The only real question left is how much longer you want to put that off.
