- We're starting a new chapter now
and we're going to take a look
at some more dimensioning techniques
that you can use in your AutoCAD drawings.
For that reason, we've got a new drawing for you.
Nice and simple.
It's called ground floor plan dot DWG.
And when you open it up in the model tab,
you can see it is quite literally a ground floor plan
with some dimensions on the drawing.
Go to the home tab on the ribbon and in the layers panel
just make sure that you are using dimensions
as your current drafting layer
because this particular chapter
is all about dimensions, we'll be placing dimensions
in the drawing and editing dimensions in the drawing.
So what we're going to have a look at in this particular video
is some dimensioning overrides.
Now these are really, really useful tools
in your AutoCAD toolkit.
So what we're going to do
we're going to look at these two horizontal dimensions here
this one and this one here.
So we'll zoom in on the left hand one first.
And you can see at the moment,
that, that particular dimension,
when I get in close is 8342.
So what I can do there is I can work with this dimension
by just double clicking on it.
If I double click on it
that opens up the text editor on the ribbon.
You'll notice.
So what I'm doing here is I'm doing a dimension override.
Now you can see there that I've got some texts there
and it's basically a text override.
It's not just a dimension override.
I can double click on a piece of text
and also edit the text.
It doesn't have to be a piece of dimension text.
However, we do have a piece of dimension text in this case
and you can see now it's kind of highlighted
in a bit of a purple, and the cursor is there,
flashing just to the left of that number eight in the box.
You'll notice, like I said
you've got the text editor tab on the ribbon as well.
That's the contextual multi-line text editor tab
that you get whenever you edit a piece of multi-line text.
So using your arrow keys on your keyboard
use the right hand arrow key and just hit it once.
And you can see the cursor goes across
to the right of the digit two in the dimension text.
So what we're going to do here is we're just
going to add a really common abbreviation
that you will often see
on drawings that are created in AutoCAD.
I'm going to put a space and then I'm going to type U N O.
Now that means unless noted otherwise.
So I'm happy with that.
That's my text edit in place.
Like, so, and then what I'm going to do
I'm going to click on close text edits on the ribbon
and it adds that to the drawing.
Now you'll notice it's prompting me now to
select another annotation object.
That's what this particular command does.
It's now saying, do you want to go
and edit another piece of annotation elsewhere?
In this case I don't.
So just press enter to finish.
So that's by double clicking on my dimension text.
Let's just pan across
to the other horizontal dimension here, like so.
The 5 9 1 0
Now this is another really cool function as well
that I really like, I can select my dimension.
I can then right click and go
to properties on the shortcut menu, click on properties.
And that will bring up the properties palette.
Now there's a lot of information going on here
about this dimension, things like lines and arrows,
miscellaneous, it's annotative, et cetera, et cetera.
I'm going to click and slide down here
and come to the text part of the properties palette here.
So there's the text panel.
Now right at the bottom there.
Can you see, there is a text override box.
Now the measurement of the dimension actually physically
in the drawing, which is a metric millimeter drawing,
is the fact that it's 5 9 1 0.
I'm going to click there in the text override like so,
and what I can do there is I can,
if I want to put a text override in,
so I'm actually going to put a text override in there
which is measure on site.
I'll put that in there like so,
measure on site, press enter once
keep an eye on the selected dimension in the drawing.
And you'll see that that text goes in there like that.
Now that literally means that I've got rid of
the measurement text in the dimension.
I can put that 5 9 1 0 back in.
What I'm going to do is I'm just going to update this a little bit
and I'm going to put an approx like so
and then a dot and then I'm going to put a space
and then I'm going to put less than, greater than.
Now that less than, greater than
allows me to basically say to AutoCAD
put the measurement value back into the text.
Now you did see it kind of disappear off the end there,
that's 'cuz I went further than the boundary
of the properties palette.
Just use the left hand arrow to come back
along the text and you'll see, it appears again,
sometimes AutoCAD does that.
If I now press Enter this time,
can you see that I've got the 5 9 1 0 back.
So when I close the properties pallet
and hit escape a couple of times
there's my measure on site, approximately 5 9 1 0.
So you can add more
to your dimensions by utilizing these overrides.
It's quite clever.
So the dimension editing and the overrides
are really quite useful.
So this dimension here will be 8 3 4 2,
unless noted otherwise.
This dimension here is 5 9 1 0 approximately
but it needs to be measured on site.
So you can actually give instructions
by using these dimension text overrides.
They're really useful features in AutoCAD.
Utilize them effectively.
