Drafting
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.

Step 4. Define the intersection of arc (X-2) and line X-B as point 3 (figure 34, view B, on the previous page).

Step 5. Bisect line 3-B and draw the bisect line so that it intersects an extension of the line X-O-Y. Define this intersection as point 5 (view C).

Step 6. Define the intersection of the bisect line and line O-B as point 4 (view C).

Step 7. Using point 5 as center, draw an arc of radius 5-X as shown in view C. Also draw an arc of radius 4-B as shown in view C. These two arcs will generate half of the ellipse. Draw the other half by symmetry (view D).

### 4. Conclusion

In this task, we covered drafting instruments and the fundamentals of geometric construction. In the next task, we will discuss the theory and fundamentals of pictorial drawings: oblique and isometric projection.
