AutoCAD TUTORIAL: Chapter 2 Drawing tools > ellipse command

AutoCAD has a wide library of commands. There are many commands which used to drawing any type of drawing. Today i am going to tell you about various method to drawing ellipse in AutoCAD.

Ellipse:

Short key: EL
There are two method of draw ellipse.

1. Using the both axis length:

Method
Select ellipse tool by short key EL or by the drawing toolbar.
Specified first axis endpoint of the ellipse by mouse click or by actual coordinate system (x,y).
Now specified end point of first axis by absolute coordinate system (@length<angle or @x,y).
After it specified first point coordinate of second axis by assuming the origin at center @length<angle or @x,y).

Example:
Draw a ellipse of first axis length 10 which is parallel to X axis and other axis length is 5
Solution:
El enter
Select first point by mouse click.
@10<0
@2.5<90

2. Using the center point:

Method
Select ellipse tool by short key EL or by the drawing toolbar.
After it press C enter.
Now specified center point of the ellipse by mouse click or by actual coordinate system (x,y)
Then specified the coordinate of first axis first point by absolute coordinate system assume origin at center (@x,y) or by simply mouse click.
After it specified the coordinate of second axis first point by absolute coordinate system assume origin at center (@x,y) or by simply mouse click.

Example:
To draw a circle whose center lies at the center of a circle whose diameter is 5 and whose first axis length is 10 and second axis length is 16 which makes 20 degree angle with Y axis.
Solution:
C enter
select a point on drawing screen
D enter
5 enter
EL enter
C enter
select the center point of circle
@10<20 enter
@16<20 enter

Exercise:
Problem 1 : Draw the ellipse whose first axis length is 6 and it make 30 degree angle from X axis and second axis length is
10.
Problem 2 : Draw a circle by ellipse command of radius 10.
Problem 3 : Draw the following diagram
