Line Weight
Line Weight is the thickness or darkness of a drawn line and in technical drawing, it helps show which parts of a design are closer, farther, or more important. Different line weights can help people read a drawing faster by making outlines, hidden edges, and details easy to spot. A very useful fact is that in many technical drawing standards, the thickest lines are used for cutting planes or main outlines, while thin lines show things like dimension lines or hatching. Using the right line weight can help avoid confusion, especially when a drawing has many overlapping parts. Many designers use a simple rule: the closer or more important the object, the thicker the line.
