g. * Approximate Ellipse*, (figure 34).

In this problem we have to draw an

approximate ellipse from the following given information: we have a major axis A-O-

B and a minor axis of X-O-Y (view A).

To construct this ellipse, perform the

following steps:

DRAWING AN APPROXIMATE

ELLIPSE.

Step 1.

Draw an arc of radius O-A, using point O as a center, such that it

intersects point A and an extension of line Y-O-X (view B).

Step 2.

Draw a straight line between points X and B (view B).

Step 3.

Draw arc X-2 as shown in view B.
