Draw Geometric Objects
You can create a range of objects, from simple lines and circles to spline curves, and ellipses.
In general, you draw objects by specifying points with the pointing device or by entering
coordinate values at the Command prompt.
Draw Linear Objects
A line, the most basic object, can be one segment or a series of connected
segments.
Draw Lines
You can close a sequence of line segments so that the first and last segments
are joined.
You can assign properties to lines including color, linetype, and lineweight. For
more information about properties, see
Work with Object Properties on page
161.
You specify the locations that define the endpoints of each line with precision.
You can
■ Enter the coordinate values for an endpoint, using either absolute or relative
coordinates
■ Specify an object snap relative to an existing object. For example, you can
specify the center of a circle as one endpoint of the line
■ Turn grid snap on and snap to a location
There are other methods for creating precise lines. A highly efficient technique
is to offset a line from an existing line, and then trim or extend it to the desired
length.
