- We're in a new drawing now
for this particular video in this particular chapter,
and it's called zero zero ground floor plan .dwg.
And what we've got is a floor plan in our model space.
And that's what I want to talk about.
I want to talk about model space and paper space.
Now model space is now commonly known as model,
and you can see the tab down here.
Paper space is now commonly known as the layout tabs.
And we have a layout tab in this drawing.
It's there, ISO A1 Landscape.
And you can see that we've got an A1 sheet set up
with a view port there, like so,
showing the view of the floor plan.
Let's go back to the model tab in the model space.
And what I want to get across here
is that model space is infinite.
You can have whatever you want in your model space.
You can set your model space up to show anything.
And what you do based on the units and things
that we've discussed previously in the course,
is you design everything real-life, full-size
to the units that you want to work with.
So when I'm working in the model tab,
and I'm working on my floor plan,
everything is real size.
So if I zoomed in on these chairs and tables
in the sort of central reception area here, for example,
we've got some sofas, and we've got some chairs.
So if I went to the home tab
on the AutoCAD ribbon, into the utilities panel,
clicked on the fly out here and did a distance measurement,
which we have discussed a little bit already.
And I use this endpoint object snap here
to this endpoint object snap here.
You can see that that distance is 1 8 2 8.80,
which is 1 8 2 8.80 millimeters in this case,
because it's a metric millimeters drawing.
But that could obviously be feet and inches.
It could be meters.
If the objects are big enough, it could be kilometers.
And so on and on it goes
with all the different units that AutoCAD supports.
I just click on exit there on the menu
to close the distance command.
And I'll double click on the wheel to zoom extents again.
So obviously this particular building is quite large.
If you look at the dimensions between the grid lines,
you can obviously see that.
We've got over here, we've got about 9.6 meters,
just over 10 meters, and then another 9.6 meters.
But obviously the dimensions are in millimeters,
so they're in their thousands.
So that's quite a big area to cover,
and that's not going to fit onto an ISO A1 sheet
in the layout tab in the paper space.
So this is why we use view ports.
So if I click on the ISO A1 Landscape layout tab,
that takes me into what is known
as my paper space or my layout tab.
You'll also notice down here on the status bar
that it changes to paper.
It tells me model or paper space there.
If I come back to the model tab,
you'll see that that says model, like so.
So it's just letting me know which one I'm in.
And also if I click on it,
it can allow me to toggle
between model space and paper space too.
So if I click on it,
you'll see there that it activates the model space,
and it activates the view port.
And I can work in the view port now.
That's a thing called floating model space.
So basically what I'm doing there
on this particular layout in the paper space,
is my view port is acting as like a frame
through a hole into the model space.
But the thing is this particular sheet
is only the size of an ISO A1 sheet,
which is actually 8 4 1 by 5 9 4 millimeters.
So how am I fitting that great big, huge floor plan,
which is approximately 30 meters by 30 meters,
which is 30 thousand millimeters
by 30 thousand millimeters onto that sheet?
Well what I'm doing is this view port, where it's active,
if you look down on the status bar,
is set to a known scale of one to 100.
And I can set differing scales there for my view ports.
So at the moment, it's one to 100,
which is what I want it to be.
It's a hundredth of its original size.
So that's why it fits on the sheet
in the paper space in the layout tab.
I'll just double click away from the view port
to deactivate it, like so.
So the whole idea is,
with model space and paper space,
is you've got two spaces to work in in AutoCAD.
Model space, you do all your designing full-size
to the units you want to use.
Paper space, or the layout tab,
is where you start communicating your design intent
by creating these scaled view ports.
In this case, one to a hundred,
where it's a hundredth of its original size,
so that it fits on the sheet,
and you can then send the sheet
to either a printer or a plotter,
or perhaps save it to an electronic file like a PDF
and send it onwards to people working on the project,
project stakeholders, clients, et cetera.
And that's the difference between model space
and paper space in AutoCAD at a very basic level.
Now, as we work through the course,
I'll explain that in more detail.
I'll show you how set up title blocks and view ports
so that you have a working drawing
that you can then send to other people,
so that they can obviously understand your design intent
and your design and your annotation around, in this case,
your floor plan in your AutoCAD drawing.
