Why do complex, multi-stage dies still trip me up?

You can design most dies now. That did not come from luck. It came from doing the work enough times that the simple cases became simple. The multi-stage ones are not a different skill. They are more parts, asked to work together, and your habit of designing the whole part at once stops helping you here. Be honest about what actually happens when you sit down with one of these jobs. You look at the whole progression and try to solve it in one pass. That is the mistake, not your ability. No one designs a ten-stage die by seeing all ten stages clearly at once. They see one stage, then the next, then how the two meet. This page will teach you a way to break a multi-stage die into pieces you can actually master, one at a time. Then it will push you to practice that way, on real work, until it becomes your normal method instead of something you have to remember to do.
