To Create and Edit Ellipses
Before creating an ellipse, keep the following in mind:
• Ellipses are drawn with a thick and thin line. The thick line always appears to the right of the creation line.
• To reverse the thick and thin lines, double click on the element or use the Switch Pens tool.
• When you apply a pen to the rectangle, it is applied to the entire rectangle (there will no longer be both thick and thin lines).
To Create an Ellipse
1. Click Ellipse. The Ellipse tool is selected.
2. Set the ellipse angle:
◦ Free angle — holding the CTRL key, define the major axis, and then the ellipse angle.
◦ Preset angle — in the Ellipse tool, select an angle from the list.
◦ Custom angle — click Ellipse > Custom. The Custom Ellipse dialog box opens. Type the ellipse angle, then click OK.
3. Define the major axis of the ellipse in one of the following ways:
◦ Click to drag the length and angle of the axis.
◦ Click to start the axis, and then click a second time to end the axis.
Once the major axis is defined, the ellipse is rendered at the present angle.
To Edit an Ellipse
Use the table below to edit an existing ellipse.
To...
Perform the following:
Edit an ellipse angle
In the Ellipse tool, select a new angle from the list or select Custom to set a custom angle.
Alternatively, press SHIFT + RMB and drag the ellipse to edit the angle.
Trim an ellipse
Click Trim to enable the trim tool.
Scale an ellipse
Drag one of the control handles towards the center point to reduce the size, and away from the center point to enlarge the size.
Rotate an ellipse
Drag one of the control handles in a clockwise or counterclockwise direction.
To Close an Open Ellipse
An ellipse with a section missing is called an “open ellipse”. You can perform all edits on open ellipses.
To close an open ellipse, select it and then click Close Ellipse. Alternatively, press SHIFT + E.
Grid Aligned Ellipses
When creating a new ellipse, the default is aligned to the grid. To create an ellipse without grid alignment, disable the grid or override grid alignment.
