curve in the end view is obtained by drawing a section through the cone and plotting the
position of points on the circumference where the cut face intersects with the circle. A
typical section is shown to establish points A and B.
At point 4 the radius of the circle is distance XY. Draw this circle as shown; it intersects
with the cut face on the plan at points A and B. Transfer width AB to the end view
and repeat the procedure. Join the points to give a polyline and use the FIT feature in
