Triangulation development
Triangulation is a geometric development process used to create patterns of conical and transition shapes. Triangulation allows you to determine the true length of a line or surface on a drawing by creating a right angled triangle
You will now watch a video that explains how the development of "a square to square transition piece" is constructed by triangulation method.
Next is the development of "a rectangular to round transition piece.
3. "Rectangle to circle
You need to practice with some drawings of your own. Try and follow the instructions by the tutors in the clips.
