Moving drawing objects
CADD allows you to move drawing objects within a drawing in a convenient manner. Unlike on a drawing board,
you don’t need to first erase and then redraw in a new place. You can simply rearrange the existing drawing objects,
as you like. This is a very useful tool for analyzing design alternatives and making quick adjustments to drawings.

TIP

AutoCAD requires that objects be selected in order to be processed. The Select Objects prompt occurs after many
commands, including the SELECT command itself.
Copying drawing objects (Fig 3)

CADD allows you to make quick and easy copies of existing drawing objects. You can copy individual drawing
objects or the entire drawing all at once. You can even make multiple copies of drawing objects within seconds.
Using the copy function is quite similar to the way the move function is used. First, you need to select objects using
any of the methods described earlier. Then you need to indicate a base point and a relocation (or destination)
point. The copied objects are placed according to the relocation point.

Making multiple copies in a rectangular fashion
There are separate functions available in CADD that allow you to make multiple copies in a linear or rectangular
fashion (commonly known as a rectangular array). You can make hundreds of copies within seconds. You don’t
need to enter a base point and a destination point. You just need to select the objects, specify how many rows
and columns you need and the distance between them.
