How to Use Modification Command - Offset & Mirror

Hello friends.

Welcome to Learn Vern.

 I am Harsh. Welcome you all to today’s video.

In the last video, we learned about the introduction to modification tools.

In today’s video, we will learn about 2 more modification tools. Where the first one is offset and the second is mirror.

So come let’s start with today’s video.

As you all know, we are learning about the modification tools right now. So today, we will gain some more information about 2 other tools, where I will explain about two more tools, which are offset first of all, and then the mirror.

So first of all let's start with offset.

So let's get to know what is offset? Suppose, I have a line here, and I want to draw the same line, at some specific distance… So I can draw it, with the line command, with that specific distance, but that is a very time-consuming process.

 For this, I have a command available, where I can easily draw the same object, with any specific distance, such as, this line or this circle. Suppose I have a circle available here, and I want to draw many other circles, but the center of the circle, for all the circles, should be the same, at that time I will select a circle, and use the offset command. That way I can just click where I want the circle, and my circles are drawn.

One more, suppose, I have a rectangle shape available here, so with this shape, I want to draw 3 more rectangles… For this, I will go to the offset command, and I will select this rectangle, then I will select the distance, that I want from this rectangle to another one, and that distance is offset. Okay.

Here also, I can enter the distance between this circle and this circle and draw this object, as per my requirement… Same way here also, between this line and this line here as per my requirement, I can specify the distance that I want. 

So come let us look at the line first.

To draw a line… Here my ortho is on, and because of that, the line that I am drawing is exactly vertical. Then I want to offset this line. So here I will type O, and enter, which is the shortcut key for offset… Now I have to specify a distance, till the point that I want my offset. For example, my requirement right now is, 0.3, so I will type 0.3 and press enter. Next, what object do I want to offset? So here, the option that is available, I have this line, I will go on this line, and select it. As soon as I select it, here, I have 2 more options available.

I can either offset on the right side or the left side, so I will click on the side where I want to offset or copy my line. As I clicked here, the line is available to us. If I want to do it again, I will select again, and then again, and again. On this side too, when I select the line and click multiple times, the line will get copied, that many times. Okay.

We have one more option… (Pause 4 sec, clicking) Suppose, I have a line here, and I want to offset this line, and this time also, we will specify the distance as, 0.3. First I will click O, and enter and then insert 0.30, and enter. But this time, here, I have an option available, at the bottom, that is multiple. So I will click on multiple, and after selecting multiple… the lines will be drawn multiple times, as I keep clicking here… Along with that, the distance will also be visible, here, as this is the distance in between the first object to the last object. Same way, as I keep clicking on this side, the line will keep on drawing… Okay… (pause 5 sec)

We will understand this once more with a circle.

So here, I have a circle and I want to offset this circle. So, I can directly select and click on offset here, then I have to specify the distance… so I am taking it 0.4, and enter. So this is offset. I want to do it again, I will select and offset, then select and click, select and click. In this manner, I can draw multiple circles with an offset, that has the same center. Or… I will select this… and click on offset…. and the distance is 0.4 and enter. but here, I want to select multiple, so I will click on multiple or type M and press enter. As soon as I click on M and enter, and click here multiple times, my circle will be drawn that many times, and the distance between the first and the last circle is also available to us… Okay.

(07/00)

Let's practice the same thing with a rectangle… (pause 4 sec)

I have prepared a rectangle here, now I want more rectangles in it… So I will select this and click on offset… The distance I am taking here is, 0.2 and enter. Okay, here also it shows me 2 options, whether I want to draw a rectangle outside of this rectangle, or inside. So I am preparing one rectangle here, and one more rectangle outside. So as you can see here, my rectangle is drawn inside as well as outside… But I have one more option available here. Where if I select this rectangle, and click on offset, and then I specify the distance as 0.3 and select multiple or I can type M and press enter. The rectangle keeps drawing till I keep on clicking here. The distance from the first rectangle to the last rectangle is visible to us here. In this way, we can use the offset command… Okay…

Now let's have a look at one more command which is the mirror…

So to use the mirror command, here I can type MI. Okay. As I type MI, and enter, as you can see this mirror option here. I can either click on the option or just press enter. So I am in the mirror command now… Here I have to select some object that I want to mirror, and then I have to Input the reference that I want to take to mirror the object...

First of all, let's have a look at what a mirror is. Suppose, I have an object here, and I want to draw that same object here. Think of it like you are standing in front of a mirror, and we stand at some distance from the mirror, okay. So that distance we can draw here. Suppose this is a mirror and there is an object in front of it, so how is the object visible to us on the opposite side or how we can draw it? So this is a mirror command…

So let us draw an object here… For that, I will click on the rectangle and draw it here… now if I want to draw a rectangle again… I will simply press enter. So again a rectangle, so I will press enter and another rectangle here, again enter and a rectangle… There is one more thing, if I right-click here, there is an option available which is repeat rectangle. Okay… (pause 5 sec) so I can draw a rectangle from here as well.

So now I want to prepare a mirror object exactly on the opposite side here… So for that… I will go on the first option here, that is, if I have a mirror available here, or a reference line that is available. And I want an object, at the same distance as here, on this side. So I will go in this selection… Or… I can select like this here, from left to right or right to left… And then I will click on the mirror, I can select the mirror from here, or I can simply type MI and press enter.

So now I have to specify the first point, that is here… And the second point here, and then I will press enter. As soon as I click on enter, as you can see here, the object is drawn exactly on the opposite side with the same distance. This was our first option…

We have one more option. Suppose there is an object, but we do not have any reference, meaning we do not have a mirror. But I still want to use the mirror command, how can I use it? So I will type MI and enter, or I will select mirror from here, and press enter. Here we do not have any specific line, for that, I will select a point here from where I want some distance and the other point here. Our mirror is ready here, but to make the mirror command available. I have to press enter again. If I don’t press enter, the mirror command won't complete... For example… I will select this and click on the mirror, this is my first point, and this is my second point, and I don’t press enter again, and instead press escape, the mirror command will not get completed. So to complete the mirror command, it is necessary to specify 2 points, and press enter after that. Okay.

So in this video today we saw how and where we can use offset, and mirror commands. For all these objects here, we have easily understood them. So we learned where and how to use the offset and the mirror command. Okay. So, where to use it and how to use it. We learned it today.

If you have any queries or comments, click the discussion button below the video and post there. This way, you will be able to connect to fellow learners and discuss the course. Also, Our Team will try to solve your queries.

So in today's video, we learned how we can use the modification tools offset and mirror in our drawing.

I hope you all will practice this. During your practice, if you have any difficulty or queries you can reach out to us on forums.learnvern.com. We will try to answer your queries as soon as possible.

In the next video, we will learn about one 3 more tools which are trim, extend and align.

Thank you.
