- [Instructor] Another extremely useful dimension feature
when you're trying to make parts for CNC fabrication
or you just have a lot of geometry on the screen
and you want to try to reduce the amount
of dimensions and the dimension stack up on the screen,
you can go to the Ordinate Dimension feature.
So if I go up again to where Smart Dimension is located
and click on the dropdown, you see
that we have three ordinate dimension operations available.
So there's regular Ordinate Dimension
which kind of goes automatically based
on your first two selections
choosing which direction it goes in
or you can decide ahead of time,
I'm going to make a horizontal set of dimensions
or a vertical set of dimensions
and that can be helpful,
especially when you're selecting a circle, for example
or a center point as your first reference in the ordinate.
Now, if I go up to ordinate,
and click on that, you'll see that my icon has changed
and there's the little ordinate dimension symbol.
I'm going to go ahead and zoom in on this first top view
and just click on this edge.
Now you can see automatically
it's trying to make a horizontal ordinate.
That's because it's staying in line
with the edge that I selected.
So if I hit Escape real quick
and try to make a new one,
I'm going to select this point instead
and you can see that it's trying
to make it horizontal,
but if I wanted to make it vertical,
I would have to hit escape,
go back and choose vertical ordinate,
select that same point and now it comes out
in the other direction so that we can go up and down.
I'm going to hit Escape one more time to leave that.
I'm going to down here to my menu
and go back to Ordinate Dimension.
I'm going to select this first edge
and drag down my zero
and that's saying that that's my first reference.
This is the zero that I'm starting from.
I'm going to move across the screen
and select my threaded holes.
So you can see as I click on each one,
it gives me another dimension down below
but they're all in the same line horizontal
across the screen and it's not a set of dimensions stacked
on top of each other.
So this can be a little bit cleaner on your screen,
a little bit nicer to manage
and you still get the same information
as if you're using a set of baseline dimensions.
It's a little bit more finicky if you want to go through
and change all your tolerances
on these dimensions
because they're all linked together
in some capacity so it can take a little bit longer
if you have to set custom tolerances
or you want to change leader options
or something like that
but I prefer this to doing baseline dimensions
for no other reason than it makes a nice clean drawing
and you still get all that information.
