The objective of this tutorial is to draw several different entities such as LINES,

CIRCLES, POLYGONS, etc..., and use several different modifying commands such as

MOVE and COPY.

AutoCAD$$ allows you to draw many predefined entities or shapes. Some entities

can be defined in many different ways. For example, a circle can be defined by a center

point coordinate and a radius, or by two tangent points and a radius. During each

command, look at the command prompt and make note of the different options. Also,

notice the commands enclosed in angled brackets $<>.$ They are the default values or

options and are selected by pressing the Enter or Space key.
