How to Draw Ellipse in AutoCAD 2018?

Drawing an Ellipse in AutoCAD 2025

Creating an ellipse in AutoCAD can be achieved through several methods, each allowing for precision and flexibility in design. Follow the steps below to master the art of drawing an ellipse in AutoCAD 2025.

Method 1: Using the Ellipse Command

1. Access the Ellipse Tool: Navigate to the Home tab on the toolbar. Find the Draw panel and click on the Ellipse drop-down menu. Select Axis, End from the options.

2. Define the Major Axis: Click to place the first endpoint for the major axis of the ellipse. This is the longest diameter. Next, click again to set the second endpoint of the major axis.

3. Specify the Minor Axis: After establishing the major axis, move your cursor to indicate the length of the minor axis. Click again to set this endpoint. The ellipse shape will be drawn according to the two axes specified.

Method 2: Drawing an Elliptical Arc

1. Initiate the Arc Tool: Click on the Home tab, then go to the Draw panel, and select Ellipse followed by Elliptical Arc.

2. Set the Major Axis Endpoints: Specify the endpoints for the major axis by clicking on two points in the drawing space.

3. Define the Minor Axis Length: Input the distance you want for half the length of the minor axis and press Enter.

4. Select Angles: Finally, specify the start and end angles for your elliptical arc. This will determine the extent of the arc in relation to the two axes you’ve defined.

Method 3: Drawing an Isometric Ellipse

1. Enable Isometric Snap: Go to the Tools menu and click on Drafting Settings. In the dialog box, select the Snap and Grid tab, and choose Isometric Snap.

2. Access the Isometric Ellipse Tool: Go back to the Home tab, navigate to the Draw panel, and select Ellipse. Choose the Axis, End option.

3. Create the Isocircle: Enter the command ‘i’ for Isocircle. Click to specify the center of the isometric circle, then define the radius or diameter as needed.

Filling an Ellipse

1. Choose the Hatch Command: Access the Hatch option from the Home tab in the Draw panel.

2. Select Hatch Type: On the Properties panel, choose from the Hatch Type list based on the desired filling pattern.

3. Specify Boundaries: Use the Boundaries panel to select how the hatch boundary will be defined. Click on an area or object within your drawing to apply the hatch.
