- [Instructor] Now in the previous video
we focused on smart dimensioning,
which adds dimensions automatically by moving around a part.
Now we're going to look at horizontal, vertical,
and ordinate dimensioning.
All this does really is constrain us
into what direction we're adding our dimensions
and makes it a little bit easier if we have some
orthogonal normal dimensions going on.
So we find these under the smart dimension drop down,
horizontal and vertical dimension.
They essentially do the same thing.
When you click on them you select two items or two points
so I'm going to select this point and this point over here
and it gives me the horizontal dimension
between those items.
Go ahead and click accept.
I'm going to do that again, I'm going to click this item
and this item.
You can see no matter where I move on the screen
it doesn't change, I'm only given that horizontal dimension.
Hit green and hit accept.
If I go in now and click on vertical dimension
I can do the opposite.
I'm going to click on these two points,
oops I accidentally selected too many points there.
I'm going to go ahead and go back to vertical dimension,
I'm going to select this point and this point.
And you can see no matter where I move
it just gives me the vertical dimension
between those two points.
This can be really helpful when you're working on drawings
specifically, when you're working with circles
and things like that it doesn't necessarily
know what to do.
It's going to be between points or when center points,
or when looking between two different entities.
So for example if I just click on this one,
that'll give me the vertical dimension of that line.
Same with if I go to horizontal,
click on a line it'll just give me the horizontal component
of that dimension.
But I can't select an arc for example
and get like a horizontal dimension of the diameter.
So that's horizontal and vertical dimensioning.
The last thing we wanted to look at
was ordinate dimensioning.
Now in here you get the same options,
you can do it horizontal or vertical.
Sometimes that can be helpful.
But usually by selecting your first item,
it orients it.
So I'm going to just select ordinate dimensioning,
I'm going to select this line right here.
Now you can see because it's a flat level line
it automatically set that as my zero
and now as I click on any other entity in this sketch,
it gives me an ordinate in that direction.
Now I can do the same thing vertically
so if I drew a vertical line over here,
went back up and selected ordinate dimension,
selected that entity first, that's my zero in that direction
and now every entity that I click on
will give me an ordinate dimension.
If you don't like the leaders, you can go in
and turn off the ordinate chain.
Again, all of these features are also available
in the drawings which is probably where you're going to
use them more, but sometimes it's good to add
all of these dimensions in your model
and then use the drawing features to pull the dimensions
that you've added into your drawing directly
and show those dimensions.
So you don't have to add them all again in the drawing
for your fabricators.
Same thing with horizontal and vertical,
it's just going to fix which orientation you're using.
So let's say for example I wanted to choose this point
but it's not going to know to go vertical or horizontal.
By using the horizontal dimension,
it automatically goes down horizontal
and I can select various points on that ordinate.
Same thing with the vertical,
I select that point again it goes automatically vertical.
And I can dimension to various things on my screen.
So all in all the dimensioning is not very complex
when it comes to smart, horizontal, ordinate dimensioning.
The horizontal and vertical dimensioning
really just help you fix your orientation
when things are hard to select
or you've got a lot going on in your screen.
