Introduction to Modify Tools
Unlock Audio Lesson
Today, we will begin with the MODIFY TOOLS section. These tools are essential for altering objects in CAD efficiently. Can anyone tell me why modifying existing objects is useful?
It saves time by allowing us to adjust designs without starting from scratch.
Exactly! Modifying tools optimize our workflow. Let's start with the **Erase Command**. What do you think it does?
I think it deletes things we've drawn.
Correct! The command syntax is `ERASE` or `e`. It's our go-to for removing unwanted objects. Now, who can think of a situation where we would use the erase command?
If we made a mistake while drawing?
Exactly! Mistakes are normal during drafting, and the erase command helps us rectify them. Let's move on to the **Copy Command**.
Copy and Mirror Commands
Unlock Audio Lesson
The **Copy Command** allows us to create duplicates of objects in our drawing. Its syntax is `COPY` or `co`. Why is copying a design element useful?
We can use the same shape multiple times without redrawing!
Right! It streamlines the drawing process. Now, moving on to the **Mirror Command**. Who can explain how the mirror command works?
It creates a mirror image of an object, usually for symmetrical designs.
Exactly! The syntax is `MIRROR` or `MI`. It’s very useful when our design has symmetry. Can anyone think of an example of where we might use this?
In architecture, like when we draw a building that looks the same on both sides!
Perfect example! Let’s summarize today. We discussed the Erase, Copy, and Mirror commands, all designed to simplify our workflow.
Offset and Array Commands
Unlock Audio Lesson
Let’s discuss the **Offset Command**. What does this command do?
It creates a new object that’s a certain distance from the original one.
Right! The syntax is `OFFSET` or `O`. We can set the distance we want. Now, what about the **Array Command**? Can anyone explain its purpose?
It creates multiple copies of an object in rows and columns!
Exactly! This is useful for repeating patterns. The syntax is `ARRAY` or `ar`. Let's think about a practical example of where we would use the array command.
Like placing chairs in a grid pattern in a room layout!
Great observation! Today we covered the Offset and Array Commands, emphasizing their usefulness in creating parallel or repeat objects efficiently.
Manipulation Commands
Unlock Audio Lesson
Now, let’s dive into the manipulation commands, starting with the **Move Command**. What does this command do?
It shifts selected objects from one place to another.
Correct! The syntax is `MOVE` or `M`. Next is the **Rotate Command**. How does it work?
It changes the angle of an object around a point!
Exactly! The command is `ROTATE` or `RO`. Students, can you think of when we might rotate an object in a design?
If we need to align it with another object at a specific angle!
Spot on! Now let’s summarize what we learned about Move and Rotate. Each command provides a powerful way to manipulate objects in your CAD drawing.
Scaling, Trimming, and Extending
Unlock Audio Lesson
As we conclude, let’s discuss the **Scale Command**. What does scaling do?
It enlarges or reduces the size of an object!
Correct! The syntax is `SCALE` or `SC`. Now, can anyone explain the **Trim and Extend Commands**?
Trim cuts an object at a boundary, and Extend makes it longer to meet another object.
Perfect! The syntax for Trim is `TRIM` or `TR` and for Extend is `EXTEND` or `EX`. Why are these commands important?
They help refine designs by making them neat and accurate!
Exactly! Great job today. We covered Scaling, Trimming, and Extending. Each command is vital in enhancing the overall quality of our drafts.

It creates a mirror image of the selected object in selected direction. It helps to complete drawing faster if the object is symmetrical about any axis.
COMMAND: MIRROR or MI
Select object; pick objects to mirror. First point of mirror line; pick a point. Second point; pick second point.
Delete old objects?
Detailed Explanation
The Mirror Command creates a flipped version of selected objects along a defined line, helping you quickly create symmetrical designs. After invoking the command with 'MIRROR' or 'MI', you select the object you wish to duplicate. You then define the mirror line by selecting two points. Finally, you get asked whether to delete the original object, giving you flexibility in your design process.
Examples & Analogies
Consider a painter using a stencil to create an identical design on either side of a canvas. The Mirror Command works similarly by allowing the user to create a symmetrical reflection without needing to redraw details.
Offset Command
