2. • Use different selection methods to select objects in the drawing.
• Move objects in the drawing using object snaps, object tracking, and
coordinate entry for precise placement.
• Use the Copy command or grips to create new objects from existing
objects in the drawing.
• Change the angle of objects in the drawing by using the Rotate command
or with grips.
• Create mirrored images of objects in the drawing using the Mirror
command or with grips.
• Use the Array command to create rectangular and circular patterns of
objects in the drawing.
• Change the size of objects in the drawing.
• Use grips to edit objects and display geometric information.
Objectives

3. An object or group of objects that you select is also
called a selection set. There are a variety of methods for
selecting, adding, and removing objects within this
selection set.
If you want to select an individual object, you simply
click it. You can continue to select additional objects as
needed. As each new object is added to the selection
set, the object's appearance changes to dashed lines.
In response to the Select Objects prompt, there are
many methods you can use to select several objects at
the same time.
Select Objects in the Drawing

4. • Used to reposition an object or group of objects to a new
location
• Command: M
• Hint: Select base point either on the original object or on a
reference point to make the move points easier to locate
Modify Commands: Move

5. • Used to duplicate an object or group of objects
• Command: CP
• Hint: Select base point either on the original object or on a
reference point to make the copy easier to locate
Modify Commands: Copy

6. • Used to change the orientation of an object or group of objects
by identifying a base point and a rotation angle that completes
the new orientation
• Command: RO
Modify Commands: Rotate

7. • Used to create a mirrored copy of an object or group of
objects
• Command: MI
• Mirror line is created by selecting 2 points
Modify Commands: Mirror

8. • The ARRAY command allows you to arrange multiple copies of
an object or group of objects in a rectangular pattern
• Example of a rectangular array using 2 rows, 2 columns, and
spacing of 100
Modify Commands: Rectangular Arrays

9. • The ARRAY command allows you to arrange multiple copies of
an object or group of objects in a circular or polar pattern
• Example of a polar array with 4 items, 360 degree angle, and
rotated objects
Modify Commands: Polar Arrays

10. • Used to change the overall size of an object
• Command: SC
 Scale of 0.50 is 50% of original size
 Scale of 2 is 100% bigger than original size
Modify Commands: Scale

11. • Used to partially delete an object or group of objects based
on a cutting edge
• Command: TR
Modify Commands:Trim

12. • Used to extend objects to a specified boundary edge
• Command: EX
Modify Commands: Extend

13. • Used for creating one object parallel to another
• Copies objects at preset distances
• Use to layout centerlines and for beginning drawings
• Command: OF
Modify Commands: Offset

14. •Used to separate an “grouped” object back into its individual
parts
•Used on blocks or cut and paste objects to get them back to the
original entity configuration
•Command: X
