AutoCAD Circles and Ellipse Commands

AutoCAD is a drafting and design software that is primarily used for creating 2D and 3D drawings. The software has various tools and commands that allow designers and programmers to create complex geometries with ease. In this article, we will focus on two of these commands: Circles and Ellipse.

Circles

Circles are a fundamental geometric shape that are frequently used in design and drafting. In AutoCAD, the Circle tool is used to create circles of various sizes and styles. To create a circle, simply enter the "Circle" command from the "Draw" panel, or type "C" in the command line.

Circle

Once the Circle tool is active, you can specify the center point of the circle by either clicking in the drawing area or by typing in the coordinates. Next, you will be asked to specify the radius of the circle. Again, you can click in the drawing area or type in the value of the radius. You can also specify the diameter of the circle by typing "D" instead of "R" in the command line.

Circle
Center point: CROSSING
Specify radius: 10

Ellipse

An ellipse is an oval shape that is created by connecting two points, called the foci, with a curve. In AutoCAD, the Ellipse tool is used to create ellipses and oval shapes. To activate the Ellipse tool, enter the "Ellipse" command from the "Draw" panel or type "EL" in the command line.

Ellipse

Once the Ellipse tool is active, you can specify the center point by clicking in the drawing area or by typing in the coordinates. Next, you will be asked to specify the major axis of the ellipse. You can click in the drawing area to specify the endpoint of the major axis, or you can type in the length of the major axis. Afterward, you will be asked to specify the minor axis, which is perpendicular to the major axis.

Ellipse
Center point: CROSSING
End point for major axis: 10
End point for minor axis: 4

In conclusion, both the Circle and Ellipse tools are essential commands in AutoCAD that allow designers and programmers to create complex geometries with ease. By mastering these commands, you can create precise and accurate circles and ellipses for your designs.
