Ellipse by center and two points

An ellipse with a given center and end points of two semi-axes is constructed by the Ellipse command.

Step-by-step instructions

1.Set the center of the ellipse.

2.Set the end point of the first semi-axis of the ellipse in one of the following ways:

•specify a point with the mouse or enter its coordinates in the corresponding fields of the Parameter Panel,

•set the length and slope angle of the axis in the corresponding fields of the Parameter Panel (the angle of inclination is measured from the abscissa axis of the current coordinate system).

3.Specify the end point of the second semi-axis of the ellipse. You can do this in two ways:

•specify a point with the mouse or enter its coordinates in the corresponding fields of the Parameter Panel,

•set the length in the field Minor Semi-Axis Length in the Parameter Panel.

The ellipse is automatically created after setting the end point of the minor semi-axis.

4.To complete operation of the command, click Finish .

Ellipse by Diagonal of Rectangle

An ellipse inscribed in a rectangle with the specified diagonal is built using the Ellipse by Diagonal of Rectangle command.

Step-by-step instructions

1.Specify the starting point of the diagonal of the rectangle described around the ellipse being created.

2.If you want to position the ellipse at an angle, enter the value of the angle of inclination of the first semi-axis of the ellipse in the corresponding field of the Parameter Panel. The angle is measured from the abscissa axis of the current coordinate system.

3.Set the end point of the diagonal of the rectangle described. The lengths of the semi-axes of the ellipse are determined automatically.
After setting the end point, the diagonal ellipse axis is automatically created.

4.To complete operation of the command, click Finish .

Ellipse by Centerpoint and Vertex of Bounding Rectangle

An ellipse inscribed in a rectangle with the specified center and vertex is built using the Ellipse by Centerpoint and Vertex of Bounding Rectangle .

Step-by-step instructions

1.Set the center of the rectangle described around the ellipse being created.

2.If you want to position the ellipse at an angle, enter the value of the angle of inclination of the first semi-axis of the ellipse in the corresponding field of the Parameter Panel. The angle is measured from the abscissa axis of the current coordinate system.

3.Set the vertex of the described rectangle. The lengths of the semi-axes of the ellipse are determined automatically.
The ellipse is automatically created after specifying the vertex of the rectangle.

4.To complete operation of the command, click Complete .

Ellipse by Centerpoint, Midpoint of Side and Vertex of Parallelogram

An ellipse inscribed in a parallelogram with the specified center, midpoint of side and vertex is built using the Ellipse by Centerpoint, Midpoint of Side and Vertex of Parallelogram command.

Step-by-step instructions

1.Specify the center of the parallelogram described around the ellipse being created.

2.Set the middle of one side of the parallelogram described.

3.Set the vertex of the parallelogram. The lengths of the semi-axes of the ellipse and the slope angle of its first semi-axis to the abscissa axis of the current coordinate system are automatically determined.
After specifying the vertex of the parallelogram, an ellipse is automatically created.

4.To complete operation of the command, click Complete .

Ellipse by 3 Parallelogram Vertices

An ellipse inscribed in a parallelogram with three specified vertices is built using the Ellipse by 3 Parallelogram Vertices command.

Step-by-step instructions

1.Specify the three parallelogram vertices described around the ellipse being created. The lengths of the semi-axes of the ellipse and the slope angle of its first semi-axis to the abscissa axis of the current coordinate system are automatically determined.
The ellipse is automatically created after specifying the third vertex of the parallelogram.

2.To complete operation of the command, click Finish .

Step-by-step instructions

1.Set the center of the ellipse and the three points through which it must pass.
An ellipse will be automatically created.

Ellipse tangent to 2 curves

An ellipse tangent to two specified curves is built using the Ellipse tangent to 2 curves command.

Step-by-step instructions

1.Specify two curves that the ellipse must touch. Curve names appear in the field Objects in the Parameter Panel, and the phantom of the created ellipse is in the graphic area of the document. The ellipse will touch the selected curves at the points of the indication.

2.Specify the point through which the ellipse should pass. It will be created automatically.
