ELLIPSE command
Creates an ellipse or elliptical arc.
Icon:
Alias: EL
描述(D)
Create an ellipse or elliptical arc from a combination of options including the center, axis endpoints, axis radius, rotation angle, and included angle.
Methods to create an ellipse
This command has 3 methods to begin creating an ellipse:
- First end of ellipse axis
- 圆弧(A)
- 中心(C)
If the PELLIPSE variable is set to 1, the Arc option is not available.
- First end of ellipse axis
- Begin creating an ellipse by specifying a point on the ellipse’s first axis then:
- 指定轴的另一端点
- Specify the end point of the ellipse’s first axis.
- Set other axis
- Specify the radius of the other axis.
- 圆弧(A)
- Begin creating an elliptical arc by specifying a point on the ellipse’s first axis then:
- 指定轴的另一端点
- Specify the end point of the ellipse’s first axis.
- Set other axis
- Specify the radius of the other axis.
- Set start angle of arc
- Specify the start angle to define the arc’s starting point. The angle is measured counter-clockwise from the positive x-axis.
- 终点角度
- Specify the end angle to define the arc’s endpoint.
- 中心(C)
- Begin creating an ellipse by specifying its center point then:
- 指定轴端点
- Specify an endpoint of the ellipse’s first axis, measured from the center.
- Set other axis
- Specify an endpoint of the other axis, measured from the center.
Additional options within the ELLIPSE command
After you begin creating an ellipse, the following options may be available:
- 夹角
- Specify the included angle, measured from the starting point.
- 参数
- Specify values for the parametric formula that defines the elliptical arc:
- 旋转(R)
- Specify 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.
