And maybe another drawing we had.
We went through the same process, but it was only concentrating on this room.
Well, then we might have that at, say, 1 to 50.
Or 1 to 40.
Okay.
And what we can do with these these viewports, this window, it doesn't have to go to fill this whole
frame.
We can use grips on it and we can bring it in like this.
So.
Let's bring it in.
And when you get a view of just that room on this drawing.
But what's important to remember, we're not changing anything about.
We've still only got one model in model space.
If I was to insert a circle that's a table in that room and go back to paper space, you can see the
table in the room.
You can see it in this view.
However many views we had, we could have 100 title blocks and different scales and everything, but
we haven't.
We're only viewing into model space to see what's in model space.
And in model space there's only one drawing.
So
that's how they use.
And you could have you could have as many as you want.
You could maybe have this at 1 to 100.
Have something.
Like that.
Okay, let's move that into the middle.
And you could have lots of these.
So a drawing.
It's fairly usual to see a drawing with multiple viewports.
But remember, you've only got one model.
You've just got lots of different layouts and that will then allow you to print this model or a portion
of it or whatever you want, any view you want on a normal piece of paper to scale without having to
change the model.
Okay, So I appreciate it can be a complicated thing.
A lot of people struggle with this.
A lot of people have been using CAD for many years, still struggle with this, by the way.
So if you haven't grasped it, if it seems a bit complicated, it will do.
It's perfectly understandable.
It's probably the one thing in AutoCAD that's hardest to teach and that's why I use this window example.
People can kind of see it that way.
You might need to watch this again.
You might need to create some of yourself and mess about with it.
That's why I've included this reference drawing.
But once you grasp it, it just becomes second nature.
For now, what I do see people doing.
If I take this.
Drawing frame or title block, which is a proper name.
And I use a clipboard, so I do a copy.
Okay.
And in model space, I paste it.
This is how I see a lot of people getting around it.
Now remember, everything's drawn actual size.
So when I've brought this in, this is.
This is the actual size.
A piece of A4 paper would be the size of that building.
So people then go, okay, well, I'm going to scale that up.
And I'm going to put it.
The okay.
And that's how people get around it.
But you can see you've messed up nothing.
Your building is still actual size, but now your title block is whatever size it needed to be.
And that's always going to be if you were doing another drawing of this building, this room, you would
make it smaller and your text would be different.
It's just that's how people get around it.
But it's not a good way of doing it.
The other way people get around it, which is even worse, is to take a copy of a building.
Okay, if I undo that?
So they would copy the building.
And scale the building down.
Now you can see that is asking for trouble because
now you're building is no longer actual size and you can't measure anything now.
You've basically lost all that information.
If someone comes along and says, Right, how long is that wall?
Oh, um, I'll need to work that out because I've changed the size.
It's just a nightmare.
And AutoCAD has this facility for a reason.
The main thing to remember is everything is drawn actual size and kept actual size.
And the way of doing that is by having a model space, which is your model of a building, the creation,
the engineering component, whatever, but the model and paper space, which is your paper.
Okay.
So yeah, try and get your head around that again.
In the projects we're going to use these.
There's lots of powerful things you can do with viewport controls, turning layers on and off and things.
We're going to look at those later in your different courses.
This is kind of an overall concept.
So if it isn't quite 100% in your mind, don't worry.
Just by using it and seeing a use case for it, it will it will kind of become concrete.
If it's really gone above your head, just rewatch this video and try and try and remember the window
analogy of looking for a window and that everything is actual size.
Okay.
Now, in paper space, you can do all the same things you can do in model space.
So I'm in paper space now, okay.
I can create objects, rectangle circles, whatever.
I can create text, I can create dimensions.
Okay.
So I can put a dimension somewhere.
The thing to remember is your units are different because you're on a different scale.
So whereas in here.
If I was to put some multiline text.
Okay.
It's going to be tiny.
A height for that is probably going to be 250, 250 units.
Okay.
In paper space, a height is only 2.5 because you've got this scaled down happening.
It's a lot smaller.
And what I tend to do and what I prefer is to have all my text and dimensions in paper space.
The way to look at it is paper space is the things you want to print out on the paper model space is
anything related to the model?
Dimensions are something you want to print out on the paper because you're going to use this same model.
So in this example, for instance, you want overall dimensions here of a building.
In this example.
You probably want dimensions.
Let me put linear dimensions.
Of the room.
Okay.
Maybe you want one to the window.
And the size of a window, because this this view you've created here is relative to just this room.
This view is relative to the whole building.
If we were to start putting dimensions in the model,
if we were to dimension the room here, and I'm not going to worry about the scale and have a look.
If we were to put dimensions here and then dimensions on the outside.
Okay, then you will see them in every view so you can see.
We've got this dimension.
It's in the model space.
I can't get rid of it in paper space because it's in the model space.
Okay, so they're shown in every view, whereas things like dimensions and text tend to be view specific.
You want them in some views, some not.
So by doing them in paper space, you can choose what you have and also the scale of them.
If you have room numbers in your plan.
If you are zoomed in here, that room number is going to be a lot bigger because you've zoomed in.
Okay.
If this was.
Let's say we had a full view in this plant and this was going to be 1 to 40.
Of that room.
Okay.
You can see if if that room.
Oh two.
Symbol was there in model space.
It would be huge in this view, but by keeping them in paper space.
You can keep them the same size relative to the rest of your drawing sheets.
So it makes sense to put it in paper space to me.
Now, you're going to get different opinion on this because it's it's an argument that's ongoing.
Some people think it should all be in model space.
Um, again, I don't, but that's just my opinion.
If you use AutoCAD yourself, do whatever you feel comfortable with.
I will say it's easier to control different views when you're doing it in paper space.
If you're going into a company, you're just going to have to do it how they do it.
Okay.
Don't go in and say I did an online course and someone told me I should do it.
Like you're probably not going to win any friends.
So just do what they're doing.
Make your life easy.
But I prefer to do all text and dimensions like that in paper space.
Now the other thing is on your drawing frame, okay, you've got text that you can change in here and
it is just normal text change.
Just double click it.
It's exactly the same.
These drawing frames are drawn.
See, it's a block.
AutoCAD works exactly the same in paper space as it does in model space.
It's just two different, um.
Kind of zones, if you like.
Now the title blocks.
They are in your resources folder for this course and you'll see ones in inches, ones in millimeters
if I just open.
And you'll see now.
We've got quite a few tabs in this drawing.
You can have as many paper spaces as you want in any drawing file.
You can only have one model space because in theory that should be where your model is.
But you might want many, many title blocks in many different things and you can separate that in layouts
a bit like you do for other things, other types of software.
And what we've got in this title block drawing, we've got the largest title block is A0, which is
the large sheets of paper.
And then we've got different sizes of paper until you get down to A4, which is the type you would have
in a normal home printer.
And for this one you could have horizontal or vertical.
So basically landscape or portrait depending what you were wanting to show.
And you can then you can change what's in the drawing frame just by double clicking the text and doing
the text edit on it.
Okay.
You can select the whole thing.
So if you wanted to use this in a future project, you can select the whole thing.
Go to your clipboard, copy.
And if we go to Building zero one and just click paste, you can see we can bring it in here.
Okay.
And now we can go back to our layout.
The rectangular viewport.
Create that and then we can give it a scale.
And it's exactly the same principle.
You have a drawing on a drawing frame to scale.
Okay.
And this is something we'll do in the project courses, in the project part of your course.
Again, this is just an overview, overview of the theory and how that works.
So hopefully you've grasped that if you do grasp that, you know more than a lot of people I've worked
with in the industry, people who've been doing CAD for many, many years never grasp this, mainly
because they don't sit down and try and get their head into it.
So if you have.
Well done.
If you haven't, please watch it again.
If it's only kind of 7,580% there, you just need to put it into practice, which you'll do in the project
part of the course.
But but that is an overview of paper space and model space, the differences between the two and why
we need two different types of spaces so that everything can be drawn 1 to 1.
