Now you can see we've got it's 100, but it's shown as 100 point and it's four decimal places.
Sometimes you might want to be that exact.
Most of the time you wouldn't.
So that is controlled under primary units.
Okay, but we've got another one here fit.
So let's look.
Let's look at them in order.
So.
Underfoot.
You can have an overall scale of your dimension, so you could scale the whole thing up uniformly.
Okay.
If you wanted, you can have your dim lines inside.
Now.
Okay.
Now, most of these options, as I said, you're not you're not really going to alter that much.
Best thing you can do is so this chapter isn't an hour long.
Click them and see what they do.
But the ones you will use most is this 100.
If you want to move out and you want more control.
We've already looked here where you could put it.
So above.
Or below.
But even even then, you've not got that much control if you click on that text.
The whole thing moves as one object.
So what I like to do under this, the one option I do like to change here, you see you've got text
movement.
Keep dim line with text.
So I like to put it on move, text.
Now what that will do if you click on Move text No leader, you get a grip on your text.
You can now move that.
Okay.
And we'll turn off o off.
You can now have much more control about where you put that without the line moving as well.
And that's good.
When you've got a cluttered drawing, maybe there's a wall above there or a symbol.
You just want to move your text to the side of it.
It gives you much more control.
The other option was to add a leader.
Now this one, when you do move it, it's going to put an arrow on that can get very cluttered.
I tend to use this no leader and just adjust it myself.
And that's you see, if you get close to the line, it'll break it for you.
That's generally all I use on this one.
Now let's look at these primary units.
Precision.
This is where we've got our four decimal places.
We can knock that down to no decimal places.
Or if you want a bit of precision, one decimal place.
So let's say this line was I'm going to add another line here.
Okay.
And it's going to be nine units.
And I'm going to put a dimension.
Onto the end there.
So now we've got it says it's 109.
We don't want it to say 109.
If someone was manufacturing this, they're not going to make it 109.
Maybe it's not that precise if you're talking precision.
Yes.
But if it's just something you're cutting out of wood, they'll just laugh with 109mm.
So we want 110.
You don't need to change all the lines to be exact lengths.
You can just say, let me collapse some of these.
Under this primary unit, you can just say, well, round it off, round it off to the nearest five,
okay.
And it will automatically kind of round that off to the nearest and you can be as exact as you want.
You could round that off to the nearest 500 if you want and it will be zero.
But that's probably asking a bit too much.
So round off can come in handy just to neaten up those dimensions, especially when you start getting
decimal places.
So if if this had said 109.975 or something and you wanted to keep the decimal place but you didn't
want it to be point nine, you can just round it up to the nearest one and it will automatically do
that.
Okay.
So that's primary units.
You can put a prefix and a suffix.
So you could type in in millimeters and it will automatically put millimeters on.
So you don't need to type that in or you could put inches.
Okay.
Um.
Or you could just put in the.
Inches, Mark.
Sorry.
That's feet.
Inches.
Okay.
So you can do that and that will automatically add this onto all your text.
And again, you can do that as a prefix as well.
So maybe you wanted it to say length.
You can put that as a prefix.
So it will add that automatically.
And now if this dimension changes, it's going to change the value, but it's still going to leave the
length of the inches.
So prefixes and suffixes.
Okay, dim units we've got.
Different notation, different ways.
So if you've got your engineering maps giving you a eight foot four inches, sometimes you want it as
a decimal, even in inches.
I know sometimes they use decimals, sometimes you want it in feet and inches.
You can change all that.
And this is again, have a play about see what it does with your precision alternate units.
Can't say I ever use that tolerances.
And you can add things so you can add symbols and tolerance.
Again, that's very advanced.
That's more of an engineering course.
This is just an AutoCAD course.
So that's the basics.
One thing I will say is if you wanted this to actually say something completely different, sometimes
it's just indicative.
Okay.
So it might this line might measure 100 units, but you want it to say.
Six miles, for instance.
I don't know.
So you can just double click it and it comes up.
It's just MDX.
So you could write six miles long and then delete what was there a day and you'll get that and it'll
act just like your dimension text.
But now and if you go under text, you'll see it's actually got a text override which is here, so you
can change it there.
But I tend to just double click it and that's dimension.
