- [Instructor] We're starting a new chapter now
in our AutoCAD essential training course.
So we're going to be taking a look
at how we work with viewports and annotation
and a little bit of annotative scaling as well.
So the new drawing is called NewMetalPlate.twg
and you'll see that it looks remarkably similar
to a metal plate drawing that we've used previously.
Now, one of the things that's really important
when you're working with viewports, annotative scaling,
annotation scales and viewport scales,
is you need to make sure that your viewports are locked.
Really important.
So right now, when you open up the drawing
you are in your model tab.
Let's go and have a look at our layout tabs
and make sure that our viewports are locked.
I'm going to come down to the plan view layout tab here,
like so,
and I'm just going to click on the edge of my viewport.
And you'll notice down here on the status bar
it's set to a scale of 1 to 2,
and you'll notice as well, that the viewport is not locked.
So the sort of mistake that I can make is I can double click
in my viewport, like that,
activate the viewport, roll back on the wheel,
and that's now totally at the wrong scale.
You can see the value down there on the status bar.
Now, one of the things that you can do in AutoCAD 2023
is this really neat little little icon on here.
So it's now come on and said viewport scale
is not equal to annotational scale.
If I click to synchronize, watch what happens.
It'll now synchronize the scale
and I can just pan without zooming.
And that is now all scaled up exactly, like so.
So I can then double click outside the viewport,
select my viewport like that,
and just click on that little padlock,
and lock it on the status bar.
It escaped deselect the viewport a moment
and if I double click inside the viewport now
and try and zoom,
it doesn't actually zoom inside the viewport anymore.
It zooms the actual layout.
So I'll double click outside the viewport there,
just to make sure that my viewport is deactivated.
So that's all locked and at right scale.
Now that's how you do it in AutoCAD 2023.
Let's jump to the sections and elevations layout.
And again, I'll click on the edge of the viewport
and you'll notice it is also unlocked.
So ideally it should be locked to maintain
that 1 to 2 scale.
Now, one of the things that might happen in AutoCAD,
in older versions of AutoCAD,
is when I double click inside the viewport,
and the viewport is unlocked, and I zoom like that.
Obviously it's now completely at the wrong scale.
You'll find in older versions of AutoCAD,
anything that is annotative will disappear.
So those dimensions will actually disappear
if you are using an older version of AutoCAD
because you don't actually have this here.
You don't have the synchronized option.
So what we'll do here is we'll do it the old way.
So if it's all like this and looking a bit wrong,
and the dimensions have all disappeared,
you need to update your scale on your status bar.
Now we know it's 1 to 2 so I'm going to make sure
that that is set to 1 to 2.
And then what we're going to do is just pan only,
no zooming now, cause we've got the right scale.
You want to get your section view and your side view
in the middle of the viewport, like that.
That's all working. Check its 1 to 2. It is.
Double click outside the viewport to deactivate.
Now another way that you can lock your viewport
is you can select the viewport and right click,
and display locked, and yes, will also lock your viewport.
So you'll notice now when you select the viewport,
it's now padlocked as well.
So you can do it on the status bar
or on the right click shortcut.
I'll just hit escape to deselect the viewport now.
So our two viewports are now locked
at that 1 to 2 viewport scale.
That's the important bit. They need to be locked.
Let's go back to the model tab
and we'll get ready to move into the next video.
