Alias: EL

Description

Create an ellipse or elliptical arc from a combination of options including the center, axis endpoints, axis radius, rotation angle, and included angle.

  1. Center
  2. First end of ellipse axis
  3. Second end of ellipse axis
  4. End of other axis
  5. Major axis
  6. Minor axis

Method

This command has 3 methods to begin creating an ellipse:

  • First end of ellipse axis
  • Arc
  • Center

If the PELLIPSE system variable is set to 1, the Arc option is not available.

Options within the command

First end of ellipse axis
Allows you to begin creating an ellipse by specifying a point on the ellipse’s first axis.
Second end of axis
Specifies the end point of the ellipse’s first axis.
Set Other axis
Specifies the radius of the other axis.
Rotation
Specifies the angle of the ellipse around the major axis. The angle can vary between 0 and 89.9. An angle of 0 degrees draws a circle. An angle of 89.9 degrees draws a very thin ellipse.
Arc
Allows you to begin creating an elliptical arc by specifying the first and the second ends of ellipse axes, and the radius of the axis.
Set start angle of arc
Specifies the start angle to define the arc’s starting point. The angle is measured counter-clockwise from the positive x-axis.
Parameter
Specifies values for the parametric formula that defines the elliptical arc:
p(b) = c + a * cos(u ) = b * sin(u )

where:

  • a = major axis
  • b = minor axis
  • c = center of the ellipse
  • u = point along the arc
Included angle
Specifies the included angle, measured from the starting point.
End angle
Specifies the end angle to define the arc’s endpoint.
  1. Start angle
  2. End angle
  3. Included angle
Center
Allows you to begin creating an ellipse or elliptical arc by specifying its center point.
