Working with Basic AutoCAD Commands
to Create Objects
You use basic AutoCAD drawing tools to create lines, polylines, curved
objects, hatched areas, and text.
Key Concepts
■
In general, each basic drawing tool displays prompts for specifying
a start point and an endpoint. You can specify these points with
the pointing device or by entering coordinate values on the
command line.
■
As you use the drawing tools, it is important that you pay attention
to the command line. Many commands prompt for more options.
■
You can use basic objects for reference. For example, polylines can
define boundaries, and construction lines can define limits.
Lines
The most basic and functional drawing object is the line. You can
draw a line as a single segment or multiple segments, and line
segments can contain arcs. You can draw multiple parallel lines and
freehand sketch lines. You can draw lines in a variety of styles by
using different linetypes and colors. Each line segment is a single
object. To draw a series of line segments as a single object, use a
polyline. For more information, see “Polylines” in this chapter.
Key Concepts
■
Draw a line segment by specifying a start point and an endpoint. A
line can be composed of one segment or a series of connected line
segments. One option in the LINE command is to close the line
segments: the start point of the first line segment joins the
endpoint of the last segment.
■
You can draw lines accurately by entering coordinate values on the
command line.
