What Is It

Hello learners! In creating your drawing in AutoCAD, you need the right tools to create accurate and precise drawing. AutoCAD provides a whole range of modify tools such as Move, Copy, Rotate and Mirror that you can use to create the image you need.

Let us explore the different modifying commands.

[illustration: AutoCAD Modify toolbar icons with callout labels: Rotate, Trim, Erase, Move, Mirror, Explode, Copy, Chamfer/Follet, Stretch, Scale, Array, Offset]

[transcriber’s note: the toolbar label is printed as “Chamfer/Follet”]

1. Move

The Move command works in a similar way to the Copy command except that no copy is made, the selected object(s) is simply moved from one location to another

[illustration: hexagon labeled “Selected Object”, “Original Object”, and “Moved Object”]

Command: MOVE or M [enter]

2. Copy

The copy command can be used to create one or more duplicates of any drawing object or objects which you have previously created.

[illustration: hexagon labeled “Selected Object”, “Original Object”, and “Moved Object”]

Command Entry: Copy or CO [enter]

3. Rotate

The Rotate command allows an object or objects to be rotated about a point selected by the user.

[illustration: rectangle labeled “Original Object”, rotated rectangle labeled “Rotated Object”, and “Rotated base point”]

Command: ROTATE or RO [enter]

4. Trim

The Trim command can be used to trim a part of an object. In order to trim an object, you must draw a second object which forms the “cutting edge”. Cutting edges can be lines, xlines, rays, polylines, circles, arcs or ellipses. Blocks and text cannot be trimmed or used as cutting edges.

[illustration: circle labeled “Before Trim” with “Cutting Edge” and “Want to trim” marked, and circle labeled “After Trim”]

Command: TRIM or TR [enter]

5. Erase

The Erase command is one of the simplest AutoCAD commands and is one of the most used. The command erases (deletes) any selected object(s) from the drawing. Remember you can always get deleted objects back by typing U to undo, from the Standard toolbar or by using the OOPS command.

[illustration: grid of lines labeled “Original Object” and “Erased Object”]

Command: ERASE or E [enter]

6. Mirror

The Mirror command allows you to mirror selected objects in your drawing by picking them and then defining the position of an imaginary mirror line using two points.

[illustration: pentagon labeled “Original Object” and pentagon labeled “Mirrored Object”]

Command: MIRROR or MI [enter]

7. Offset

Offset is probably one of the most useful commands for constructing drawings. The Offset command creates a new object parallel to or concentric with a selected object.

[illustration: square labeled “Original Object”, square labeled “Single Object”, and nested squares labeled “Multiple offset option”]

Command: OFFSET or O [enter]

8. Array

Using the Array command, you can duplicate existing objects in a rectangle or circular (polar) pattern. You can select which type of array to use in the Array dialog box. Click the Rectangular or Polar options to see point, distance, and method requirements for each type.

[illustration: circle of small circles labeled “Polar Array”, grid of small squares labeled “Rectangular Array”, and curved row of small circles labeled “Path Array”]

Command: ARRAY or AR [enter]

9. Chamfer

The Chamfer command enables you to create a chamfer between any two non- parallel lines as in the illustration below or any two adjacent polyline segments. Usually, the Chamfer command is used to set the chamfer distances before drawing the chamfer. Follow the command sequence below where the chamfer distances are changed to 20 before the chamfer is made.

[illustration: corner labeled “Chamfer Distance 1 & 2 zero” and beveled corner labeled “Chamfer Distance 1 & 2 non zero”]

Command: CHAMFER or CHA [enter]

10. Fillet

The Fillet command is a very useful tool which allows you to draw an arc between two intersecting lines or adjacent polyline segments. You need first to use the command to set the required radius and then a second time to select the two lines.

[illustration: intersecting lines labeled “Original Object” and rounded corner labeled “Radius= 0.50”]

Command: FILLET or F [enter]

11. Stretch

The Stretch command can be used to move one or more vertices of an object while leaving the rest of the object unchanged. In the example below, a rectangle has been stretched by moving one vertex to create an irregular shape.

Command: STRETCH or S [enter]

12. Scale

The Scale command can be used to change the size of an object or group of objects. You are prompted for a pick point about which the selection set will be scaled.

Scaling can then be completed by picking a second point (not always easy because it can sometimes be difficult to precisely control the scaling) or by entering a scale factor at the keyboard. For example, a scale factor of 2 will double the size of the objects in the selection set and a factor of 0.5 will reduce them into half.

[illustration: octagons labeled “A. Selected Object”, “B. Selected Object”, “Scale factor= 0.50”, and “Scale factor= 2.0”]

Command: SCALE or SC [enter]

13. Explode

The explode command breaks the compound object into its component objects.

Command Entry: Explode [enter]
