The directrix is a tangent to the arcs. 1. Draw the Line of Eccentricity at 45 degrees 2. Go back from the focus at 45 degrees and drop parallel to the axis 3. Label V. 4. Draw a line parallel to the Directrix through the focus. This is the Latus Rectum pick points every 10mm a long the axis (doesn't have to be ten just a simple choice) 5. Project these lines upwards parallel to the Directrix until they hit the Line of Eccentricity 6. Then project parallel to the axis to the Latus Rectum. 7. Rotate the intersection between these lines and the Latus Rectum back to their vertical ordinates. 8. Freehand sketch the curve For the tangent Join this Q to F. From F go 90 degrees to line QF until you hit the directrix and join back to Q. Draw the normal and label the normal and tangent
