What is a dieline?
A dieline is a 2-dimensional graphic design of the outline of a packaging box, which shows the box cut line and the fold line. Usually the cut line is represented by the solid line and the fold line by the dotted line in another color.
How to create the dieline?
Adobe Illustrator is widely used in the creating of the box dieline. However, AutoCAD seems much more powerful when the box has a complex design and structure. AutoCAD makes the design more accurate and easy when the complicated flip, rotate, and mirror are involved. Personally, I prefer AutoCAD when I need create a dieline.
