Sketch > Ellipse and Elliptical Arc

In the ribbon, as well as in the automenu of the Sketch command, options of ellipses and elliptical arcs creation are grouped into a drop-down list. The presence of the drop-down list is indicated by the black triangle near an icon of an option displayed, when the list is folded. In order to unfold the list, either click a triangle in the ribbon, or click and hold on an icon of an option displayed, when the list is folded. This icon corresponds to an option used last in the current CAD session. When the Sketch command is launched, any option can be called via keyboard without unfolding the list.

Ellipse by Center and Point

This option allows you to create an ellipse by specifying consequently its center, a point defining the length of one semi-axis of the ellipse, and the value of the second semi-axis (radius or diameter).

As with other sketch elements, you can set the position of points by simply clicking in the drawing window or by specifying exact values in the parameters window.

Ellipse through Two Points

The option allows you to create an ellipse by specifying two points in succession - the ends of one of its axes, and then specifying the value of the second semi-axis (radius or diameter).

Elliptical Arc

After calling the option, you should specify four points: the center of the ellipse, the starting point of the arc, the end point of the arc, and the additional point on the arc of the ellipse defining its position. The position of the points can be set arbitrarily, using , or exactly, using the parameters window.

After specifying the center and boundary points, an arc of the ellipse appears. It follows the cursor. The cursor determines the position of the additional point of the arc.

Upon specifying first three points, a dynamic preview of the arc starts following the cursor in the drawing window. If a preview does not appear, then it is impossible to create an arc passing through the current position of the cursor. Alternatively the coordinates of the last point can be set in the parameters window. A warning is displayed in a special field of the parameters window, when you try to specify invalid coordinates of the point.
