[Instructor] We're staying in our annotation dot DWG file
and you can see that we've got our notes
and our bolting plate plan tax there.
And what we did in the previous video
was set up a dimension style,
to allow us to start adding dimensions to our bolting plate,
to communicate our design intent.
Now there's a couple of little settings
that I want you to set up first,
before you start dimensioning.
So in your layers panel
in the home tab, on the ribbon,
make sure that you place your dimensions
on the dimensions layer.
So always good to make sure
that the relevant objects are on the relevant layer.
Now have a look at the status bar
at the bottom of the screen.
Can you see, it says one to one there
and if you click on that little fly out arrow
there's all these different scales available to you.
Now, this particular scale that we're looking at
is your annotation scale in the model space.
I want you to leave it set as one to one.
Now there's a reason for that
and you'll find out more about that in the next chapter.
The chapter that talks about setting up things like
title blocks and scaled viewpoints and so on.
Now the reason,
that I'm deliberately leaving the annotation scale
at one to one is so that you can see
why the annotation scale is there.
So let's start dimensioning now.
Now you can dimension off of the annotation panel here
on the home tab on the ribbon
or you can go to the annotate tab on the ribbon like so
and there's our dimensions panel there.
Now I prefer to dimension
off of the annotate tab on the ribbon.
The reason being
there's a really nice little layer override.
Can you see, it says, use current layer.
So if you've forgotten in the home tab
just go to dimensions here
and the annotate tab you can go,
Hey, I want the dimensions layer.
So you can override the current layer
even if it isn't the dimensions layer very useful.
Also, you can select your style, which is training
like so as well.
Now, dimensioning is very simple off of the annotate tab.
You've got all your dimensions here on this fly out here.
So you've got linear aligned angular
arc length radius, diameter, jogged and ordinate.
And if I just had a scape, they'd still lose that menu.
I've also got this thing here called automatic dimensioning.
It's just called the dim command, the dimension command.
And that allows me to automatically dimension objects
in Auto card.
We do cover that a little bit later in the course though.
So we're just gonna use this little fly out here.
Now I'm gonna go for a linear dimension initially
make sure that your object snaps are on.
Otherwise you will not dimension accurately.
So I'm gonna go end point snap there
as an origin end point snap there as an origin.
When I drag upwards, now you'll see the dimension appear
drag it up a little bit to about there and click.
Now, You'll notice everything looks remarkably small
but if you zoom in real close,
you'll see there that there's my 1402.1.
So it's 1,402 millimeters point one.
Now you can see there that point one,
if you work in a millimeter is kind of inconsequential.
So what we can do there is actually edit our dimension style
on the file.
I'll click on the arrow here.
There's training there I'll go to modify.
I'll go to fit or units.
Either one will work.
I'm gonna change the precision there to that one.
If I go to fit
what I could have done is placed the text manually.
I could have rounded up the scale.
I could have scaled the dimensions to the layout.
There's lots of different settings there as well
but allow me to tidy up the dimension.
So I'll okay that, and then I'll close it
and you'll see that updates to just 1402, like so.
So if I now zoom out,
you'll see that the arrowheads there as well,
they're right on the end,
but they're all just very, very small.
And the reason they're very small
is our annotation scale here
is set to one to one,
which means that these arrowheads and the text and the lines
are all one-to-one
they're full size in the model tab down here.
Now don't worry about that at the moment
that will become a lot more apparent in the next chapter.
What I'd like you to do now is place a radius, a diameter
and an angular dimension.
So let's do that.
Let's go here.
We'll go radius.
We'll select the left hand circle,
drag the radius up to about there and click
we'll then do a diameter.
So let the middle circle drag that up.
Now you can line it in with that one.
If you want to, or you can bring it to a different position
it's entirely up to you like, so, and then we'll do angular
which is just here and we'll pick two lines.
I'll go for that line
and that line and just drag the angle out like that.
So like see we've dimensioned up the drawing,
but we've dimensioned it in a way where our annotation scale
is left at that one to one down on the status bar.
