Okay.
So we're getting through it now, getting through these basics, and we're just going to look in more
detail at lines now.
So I'm going to draw a window.
Window Select.
Remember left, click left, click again, press delete.
And let's look at a basic line.
So we left, click the line and you'll see it's asking us to specify the first point.
Again, if you don't have this these boxes and this text, it's f 12 to turn it on and off.
So you can see it's asking for a point and we're going to look at coordinates a bit later.
For now, just left click anywhere in the screen and the options here.
We're confronted with these boxes again and you'll see.
It's asking you for two things.
Okay, so the highlighted box in this case is the length.
Let's say we wanted to draw a line which was 1000mm and it was drawn at 45 degrees.
So it was kind of like that.
Okay, so we type in a thousand and then again, not don't press enter.
If we press the tab key, we've now switched to the other box and you can see this is locked.
Now we've told it the line is 1000mm long, so it's not going to let us change that.
What it does need to know is the angle.
Okay.
With that there being zero.
So we can type in here 45 and then press return and it's created our line 1000mm long at 45 degrees
and it's continuing the command.
It will continue the line command until we say different.
So if our next line wants to be 500, we type that in tab and maybe this is zero degrees.
Okay, press enter and there we go.
And we can carry on doing that.
Until we've finished.
Maybe we just want to draw a line by eye.
You can just do that.
You don't need to type anything in.
Okay.
Maybe we knew the length.
The length of this line was going to be a thousand.
You can press tab, but we don't know the angle.
We can put any angle we want.
We can just and it will tell you what the angle is, but you don't have to type it in.
So maybe we just want to do it by eye there.
Okay.
And you can carry on going like that until you're finished.
Or you can go back to the start and do right click.
Now, one thing you may notice here, if I go back to the start, when I get near the end of this line
here, I get this little kind of green box and it'll come up with a piece of text and end point.
Okay.
And that's called a no snap.
We're going to look at that in a in a chapter coming up.
So don't worry about that for now.
I'm just going to end it there by right clicking.
And there we have a line.
But as I said before, if we select any points on this line now, they're going to be individual.
So I'm going to left click and draw a window all around that and delete it.
And we're going to do the same with polyline.
So left click, polyline again, exactly the same.
We're just going to start anywhere and it's exactly the same.
You can see it's asking us for a length and an angle and we could type in those if we want this one.
Maybe a thousand tab.
45, enter.
Okay.
And you'll see.
Before when I typed in 45.
In fact, let me show you this again.
If I type in a thousand for the length and then I do tab.
Okay.
As well as actually typing in the angle.
You can you can you can tell AutoCAD which side you want to go.
So obviously, with 45 degrees, we could be 45 degrees up here or we could be 45 degrees here.
Okay.
Now what I can do, I can move my mouse and I could kind of do it by eye like that.
You can see it's telling me that's 45.
I could left click there.
Okay.
If I go 1000 tab, I could do it down here.
I can.
I can do it anywhere.
So I could do 45 down here.
Okay.
But you'll see 45 that way and 45 that way.
It's basically seeing it as the same.
So you can do that as a kind of a mixture of your of by doing it by eye and typing it in.
Let's say I knew, I knew it was 47 degrees.
I didn't want to kind of try and be exact like this.
I'm going to type in 47.
Okay.
With my mouse up here.
It's locked it to that.
And you can see if I press tab, it's locked it now if I delete that.
Okay if I do that again, type in 1000 and then tab.
If I move my mouse down this way, as long as it's in the on the correct side and type in 45 tab, it's
gone 45.
So it depends which side your mouse is.
You can just move your mouse.
Okay.
And that goes with length as well.
If.
So if I wanted my line, say 3000mm in this direction, I just move my mouse over here.
Again, I'm not trying to.
I'm not trying to get it to free.
I'm just moving it in this direction.
Letting go of the mouse, leaving it there.
Type in 3000 tab and it knows that you want three files in that direction because it's moving it towards
your mouse cursor.
Okay.
Now if I wanted it 40 kind of 45 degrees out there, I'd have to put in 135 because it is still taking
it from the same zero point.
Okay.
So you have 45 degrees that way, 45 that way.
But over here, it would be the kind of one, three, five either direction because there is zero.
So you would put you would move your mouse up here generally in that direction, type in one, three,
five and may go into and you can carry on doing that again.
You can just do it by eye.
If you wanted.
And I'm going to right click to finish.
And now when I click that, I actually did it in two different stages.
So we've ended up with two polylines.
Okay, now the thing with Polylines, we don't need to be straight lines at all.
So if I left click Polyline again and I'm just going to click anywhere, you will see this bit of text
next to my cursor.
It actually says Specify next point or and then it's got a pull down arrow.
And what that's saying is there are other options.
You don't have to just specify the next point and the other options are down here.
So we can do an arc half width length.
On the width.
Now the main thing you do here is the arc.
Okay, so if you wanted a curved line, you could select Arc.
And when you get these options down here, you might notice one letter.
It's usually the first letter, but not always.
But one of them is in blue and it's a higher case.
That's giving you a clue to the shortcut, the keyboard shortcut.
So if you want to do Arc, it's a return.
If you wanted to do length, it's l return.
Okay.
So I'm going to do that again.
I'm going to click Polyline.
I'm going to left click anywhere, and this time I'm going to click with the left button arc.
And now.
We get the option to draw a curved line and it will carry on doing arcs until we tell it either to end
the command or we can go back down here.
And quit lying and go about two straight lines.
Okay.
And then and you can carry on swapping between the two as much as possible.
Now with Axe, polyline, Axe.
When you draw them, generally you draw the end point of the arc.
You'll see it puts its own kind of curving based on the previous one.
Just click to the endpoint and then right click to finish and what you can do, you can edit these later,
but that's grips.
We're going to look at grips in another chapter basically.
For now.
I wanted to show you again when we click on that, it selects the whole thing.
We can delete that.
So Polylines come with this a line.
You cannot just say a line.
There is no other options.
With polyline.
You get these options for arcs and things like that.
Okay?
And you can click left, click that, or you can just type in a return and that will do the same thing.
It depends whether you prefer clicking or keyboard shortcuts.
In this course.
We're not going to use keyboard shortcuts much just because it's harder for me to show them to you.
Sometimes you do a course and people are using shortcuts and you don't understand how they've done a
command because you missed the shortcut.
Or you you see as a command change because you can't see the mouse.
That can sometimes confuse people.
So.
Okay, so we're not going to use that many keyboard shortcuts in this course just for that reason you
wouldn't see what I'm doing.
Okay, so with Polylines, you can do polyline, edits and more advanced things.
We'll look at those later.
But that's a basic overview of the lines, the line and the polyline.
We also have this line here, which is arc.
So.
Whereas with a polyline we had the option to do lines and arcs within the same line if you were doing
it separately.
So let's just say you drew a random line like that and you wanted a curve without being a polyline for
whatever reason.
You can do an arc and an arc.
As it hints to here, it's going to ask you for three points.
So.
Start a middle and an end, and that's the best way to get used to these.
That, we've just learned, is to just click them, play about them, Just start creating some basic
shapes.
With or without dimensions and just get used to using them again.
Because we set up our mouse with the left click and the right click to finish the command is right click.
Okay.
But what we can also do if we now wanted to draw that line again.
So let me show you if we selected polyline, okay, And we left click left, click left, click right
click to end.
And now I want another polyline.
We can right click and it will repeat the last command.
So anytime whatever command we use, whether it's move copy, any of these rectangle, if you then want
to do it again, all you need to do is right click mouse and it will repeat the last command.
That's one of the reasons we set it up that way and it really does speed things up.
But you'll see me doing that in this course.
And so I'll do a command and then I'll do it again.
And you might think, Well, mine's not repeating.
It needs me to click up here.
What I'm.
All I'm doing is right clicking the mouse to repeat the last command.
Okay.
So if you see me doing that, that's why.
Okay.
In the next chapter, we're going to look at.
Oh, snaps and object snaps.
