# Creating Ellipse

To display a command parameter to be executed, click / of command parameters, or press Tab key or / key on the keyboard.

1. Click [Ellipse] on [Shape] menu.
Then you will be able to create an ellipse.
2.  Supplemental ▪ You can enter into the ellipse creating status by clicking on [Shape] toolbar.
3. Click the center point of an ellipse on the drawing.
4. Specify the diameter 1 of an ellipse.
When specifying coordinates deciding the length of the diameter 1
Switch the parameter on Command Window to [Point to decide diameter 1] box, and click a point to decide the length of the diameter 1 on the drawing.
The distance between the clicked point and the center point will be the length of the diameter 1.
When specifying the length of the diameter 1
Input the length of the diameter 1 of an ellipse in [Diameter 1] box on Command Window.
5. Specify the diameter 2 of an ellipse.
When specifying coordinates deciding the length of the diameter 2
Switch the parameter on Command Window to [Point to decide diameter 2] box, and click a point to decide the length of the diameter 2 on the drawing.
The distance between the clicked point and the center point will be the length of the diameter 2.
When specifying the length of the diameter 2
Input the length of the diameter 2 of an ellipse in [Diameter 2] box on Command Window.
6.  Supplemental ▪ Among the diameters 1 and 2 specified, the longer one is used as the major radius, while the shorter as the minor radius.
7. Specify the rotation angle for an ellipse.
When specifying coordinates for the rotation angle
Switch the parameter on Command Window to [Point to decide rotation angle] box, and click a point to decide the rotation angle.
An ellipse will be created using the clicked point as the rotation angle.
When specifying a rotation angle
Input the rotation angle of an ellipse in [Rotation Angle] box on Command Window.
An ellipse will be created using the input rotation angle.
 Supplemental ▪ You can specify the center point, point to decide diameter 1, point to decide diameter 2 and point to decide rotation angle by inputting X and Y coordinates in [Center Point], [Point to decide diameter 1], [Point to decide diameter 2] and [Point to decide rotation angle] boxes, respectively.
