Insert two pins [they become the two focal points] vertically into a piece of paper or two nails into the ground. Fasten two ends of a thread or string, making sure that when you are finished the loop of string will easily loop around the pins. Loop the string around the pins. Now take a pencil or marker and mark the ellipse out on your surface keeping the string taught.
It depends what ellipse you will draw :P
No. Both foci are always inside the ellipse, otherwise you don't have an ellipse.

No.
"Ellipse" is a noun.

To draw ellipse or circle shapes and paths.
isn't it an arty word, like when you draw an ellipse-- so when you see/draw something with an ellipse you call it an elliptical drawing
write a program draw circle and ellipse by using oval methods in java
One can create a perfect ellipse using two pins on a piece of string and a pencil. Place the pins at opposite sides and then loop the string around them. Finally place the pencil in the loops and pull it around the pins to draw the ellipse.
To draw an ellipse passing through points A, B, and C, you can use the property that the sum of the distances from any point on the ellipse to the two foci (A and B) is constant. Since points A and B are 100 mm apart, they will be the foci of the ellipse. Point C being 75 mm from A and 60 mm from B means it lies on the ellipse. Using this information, you can construct the ellipse by finding points that satisfy the distance property.
The major axis is the line that joins the two foci (focuses) of the ellipse. If all you have is a picture of an ellipse and you don't know where the foci are, you can still find the major axis in a few seconds: It's the longest possible line that you can draw completely inside the ellipse, and it's the line straight across the ellipse between the two opposite "points of the egg".
Circular segment
A circle is perfectly round, and has one center. An ellipse is like a circle with TWO "centers", and each "center" is called a "focus". The plural of "focus" is "foci". Take a piece of string and tie a loop in each end. Put a pin through the loops, and hold it still in the center of the circle. Place the tip of your pencil at the center of the string, and you can draw a circle by keeping the string taut. Now take TWO pins, and put one pin at each end of the string; place the pins at some short distance apart, and hold them there. Place your pencil and draw, and the shape you draw will be an ellipse. The two pinpoints are the focuses, or foci, of the ellipse. Eccentricity is a measure of how far the ellipse varies from a circle. An ellipse with an eccentricity of zero _IS_ a circle, while an eccentricity of 1.0 is a straight line, with that string stretched out straight. In astronomy, every natural orbit is an ellipse.
use the rhombus method....one of the methods my prof told me hehehe...
Choose Ellipse tool from toolbox, hold down Shift key, click and drag.
