AutoCAD2010/Draw Commands/Ellipse, Polygone and Spline commands

ELLIPSE
This command is used to draw ellipse and the abbreviation of this command is EL.

POLYGON
This command is used to draw a regular polygon and its abbreviation is POL.

SPLINE
The SPLINE command creates a particular type of spline known as a Non uniform rational B-spline (NURBS) curve. A NURBS curve produces a smooth curve between control points. This command is used to draw a curved line in which a set of points is specified where the line passes, and then we define the tangent slope at the starting point and then at the end point.

There are three ways to activate these commands:
1. From tools bar menu, choose Draw >> Command.
2. Click the Command icon from the ribbon.
3. Type Commands name in the command bar or its abbreviation.
