Building centerlines
By default, ellipses are constructed without centerlines.
To create an ellipse with centerlines, enable the option With Axes on the Parameter Panel.
Centerlines are a systemic macro-element – center mark. The center mark is not connected with ellipse and is not rebuilt during its further editing (changing parameters or position).
You can also add axes to the ellipse using the Center mark.

While working in parametric mode The center mark is created associated with the ellipse. |
Line Style Selection
The current line style is displayed in the field of the same name in the Parameter Toolbar. To change the style, expand the list Style and select the desired line. More about selecting line style...
Remembering parameters
When sequentially building ellipses that have a number of identical parameters, the values of these parameters (common center, same semi-axis length, etc.) can be remembered until the command is completed. To do this, specify the parameter values common for the objects, click the 
Remember Status, after which continue constructing. More information about remembering parameters...
Example 1. Construction of several ellipses with a common center.
1.Call the Ellipse command.
2.Specify the center of the ellipse.
3.Click the button Remember Status.
4.Sequentially set the end points of the semiaxes of the ellipses to be created.
Example 2. Construction of multiple ellipses which are tangent to the same object.
1.Call the Ellipse tangent to 2 curves command.
2.Pick the curve that the ellipses should touch.
3.Click Remember Status button.
4.Consistently specify the second curves and points to build ellipses.
