What did you discover?
You’ve learned how hard it is to give clear, step-by-step instructions. Your drawing computer draws exactly what you tell it to draw. If you leave something out or if your instructions are unclear, the copy won’t look anything like your original drawing.
This also happens when you’re programming a computer. If you leave out a programming step, or if your instructions are unclear or incomplete, the computer won’t do what you want it to. Precision is key in programming.
