Right.
So let's get started with our drawing.
And if you're on this blank screen that comes up when you first start AutoCAD, just go up here to New.
And select.
You can select this one.
Okay.
And click Open.
And now we've got our blank drawing here.
Try and make sure your AutoCAD is set up the way we set it up in the basic modules.
So your trim mode should be set to one and in your options you've got your right click, mouse setup,
that kind of thing.
So we're all working the same way and let's begin drawing our building.
So the first thing we're going to do.
It's just create this external thick wall here and kind of the outline of our building.
So it is just a rectangle which is 20m by ten meters.
Again, if you're working in feet, you can go by these dimensions.
If we go back and again, make sure your units are set up the way you want to work.
I'm going to check this.
Actually, this is inches.
So I'm going to set this up in millimeters and decimal, okay?
And I'm going to go up here and I'm going to click a rectangle.
So we're just going to the basic like we did in the Basic Objects chapter.
We're just going to create a rectangle and it's going to be this two corner rectangle.
Now I'm going to start I'm going to start down here.
This is our zero zero origin.
Okay?
So I'm just going to go somewhere near that.
You don't have to start there.
There's no reason why you'd need to start there.
Really.
I'm just going to go down here somewhere close and I'm going to left click.
And now I'm going to pull out a rectangle and I'm going to type in our dimension.
We're in millimeters, so it's 20,000.
And then the tab key to switch to the other dimension.
And you can see already we we're way out in terms of where we're zoomed.
So I'm just going to type in the 10,000 and press enter and now I can double click my middle wheel to
zoom extents and just zoom out a little bit with the wheel.
And there we have it.
So this is our building outline and it's pretty much at zero zero.
Not that it matters, but I'm just because this X and Y symbol can sometimes get in, I'm just going
to drag it out to about there.
Okay.
Just by using the move left, clicking right click and then drag.
And that's a nice position for our building layout to start in.
The external walls are 300mm thick, okay?
And that's all the way around.
So the easiest way to do that, to get a line 300mm inside this one would be to use our offset command.
So I'm just going to left click offset and now it's asking us a distance.
So 300 and and then select the object and click inside Simple.
So now we have our external wall, which is 20m by ten meters.
Again, if you were doing that in feet and inches, it would be exactly the same way, but you would
use the one foot thickness here.
Okay.
So depending whether you're working in all inches or feet and inches, it's 12in or 1ft.
But you just type that dimension in and then offset the same way.
Again, I don't want to show every single measurement as feet and millimeters or it's going to get a
bit long winded, but it is exactly the same.
Whether you've typed in 300 or 1ft, you would have got similar results.
And as long as you stick to the same thing, don't do one thing in millimeters and then start adding
feet or start joining feet and adding millimeters, just whichever you're using, use that throughout
and you'll be able to follow along Fine.
So from now on, I'm just going to work in millimeters.
But it should be obvious that if you're in feet, you just follow along with these measurements.
So that's our external wall.
We've got this 20m by ten metres and 300mm thick.
And in the next chapter, we're going to look at putting some internal walls in here.
But first, we want to save this drawing.
Okay, So if you click on save and then give it a name, save it somewhere on your computer, That way,
if AutoCAD crashes or something, you're not going to lose your work.
So save.
I mean, give it a name.
In this case, building layout.
Just click save.
Okay.
So I'll see you in the next chapter.
