Isometric Ellipse (4-center method)
1. Draw an isometric equilateral parallelogram with sides equal to diameter of circle.
2. Join the mid-point of each side to the nearer end-point of the opposite side.
3. Draw arcs of radius r and radius R.

True Length line and Point View
• True Length:– Place an auxiliary view
parallel to the line– Project line on to the auxiliary
view.
• Point View:– Find true length first– Place auxiliary view
perpendicular to true length line
– Project line on to 2nd auxiliary view.

Edge View and True Shape Plane
• Edge View– Draw a line in the plane
parallel to a “folding line”– Project this line into the
adjacent view.– Find a point view of the this
line and project the other points of the plane.
• True Shape– Place an auxiliary view
parallel to the edge view– Project the plane into
auxiliary viewAF
