Development of Cone
The document outlines the 7 step process for developing the cone of a 50mm diameter and 60mm height cone. The steps include: 1) Drawing the front and top views of the cone and dividing the top view into 8 equal segments. 2) Drawing line segments from the front view and arcs based on the radii. 3) Segmenting the main arc into 8 equal parts based on the top view distances. The development allows for the cone to be flattened into a 2D pattern.
