Drawing Entities

You can use drawing tools to create new entities such as Lines, PolyLines, Arcs, Circles, Ellipses, and Splines.

You can use InfiniteLines, Rays, and Points as constructing tools.

As you sketch, you might be prompted to specify points such as the center point of a Circle, or the start and end point of a Line. You can enter coordinate values at the command prompt or in the graphics area. To use the sketching tools efficiently, use the coordinate input methods and EntitySnap options.
