- We're staying in our ground floor plan dot DWG file.
And you can see it's still zoomed in
on the table that we created previously.
I'm just going to roll back on the wheel, a couple of notches
and pan across a little bit to this space, to the left.
So there's our new table.
We're going to go into this space to the left now.
We're going to create a similar table in this space here.
Now we're going to create a table of the same size
but we're going to use some different tools to do it.
So now we're going to have a look at Polar and Ortho.
Ortho stands for orthogonal.
And what it does is it basically restrains you
to the X and Y axis.
So basically it means that you can only draw horizontally
or vertically if you're drawing lines and things.
So we're going to take a look at those now.
Now you'll remember we've already touched
on polar a little bit.
So we're going to use polar first.
I'm going to come down here to polar, like so, there it is
it's on, make sure it's on.
Click on the little arrow next to it
and just make sure that's set to 90 degrees.
That way you're using 90 degree increment.
You'll also notice that it's just done an automatic save
on my little command line there at the bottom of the screen.
It does do that sometimes.
So be aware of that,
it does cancel the command sometimes
when it does an automatic save.
So this time we're going to draw the table
using a different drafting method.
So we're just going to use lines this time
because I want to use the polar tracking
and then I'll show you how to do it orthogonally as well.
So we're going to go to basically up to here
to the line command here on the draw panels.
So click on line, come into the drawing area.
And we're in this area this time, to the left
of where we created the other table.
So I'm going to click once, drag horizontally
and can you see my polar track kicks in?
So what I need to do now is drag across to the right.
And this is where polar tracking is incredibly useful.
It's allowing me now to type in a distance
three, five, zero, zero.
I just press enter now
and that distance is basically created at the right angle
'cause the polar tracking is looking after it for me.
So as I come vertically upwards, it's the same process.
Get the polar tracking line kicking in that's at 90 degrees.
I type in 2000 and enter and you can see there
that I've drawn a vertical line.
Horizontally to the left now drag the mouse again
three, five, zero, zero in the box, press enter.
And as you can see, I've got one more line segment to do.
Now normally I would encourage you to right click and close.
What I'd like you to do this time,
utilize your object snaps, come down to the endpoint snap
when it highlights like that, just left click once
and then enter to close your line command.
So that's using polar tracking, which we have already
touched on a little bit during this course already.
Now, let's do something different.
Let's remove these lines.
one, two, three and four, just click on them like that
right click and erase them like we've done previously.
This time we're going to use the orthogonal tool
and what the orthogonal tool does is like I said
it ties you into the X and Y axis, but you can still
type in distances using direct distance entry.
So if you come down to the status bar
there's polar tracking there
to the left of it is Ortho mode, orthogonal
and it restrict the cursor orthogonally.
Now, if you switch it on you'll notice polar turns
off you can't have both on at the same time.
So now I'm tied into the orthogonal setting or Ortho.
Let's go back up to that line command,
click on it in the draw panel
and come into the drawing area.
So if I click once now and no matter which way I go
I can only go horizontally or vertically,
notice I cannot go diagonally
no matter how hard I try and move the mouse
can you see that?
So I'm going to drag to the right,
now you'll notice the polar tracking kind of still kicks in.
It still gives me the angles there
but I'm not actually using the polar tracking line
because Ortho is locking me down to horizontal or vertical.
So I can still do the three, five, zero, zero, enter.
And now I just move upwards, 2000 again, enter,
drag this way to the left three, five, zero, zero again
and enter and again, make sure you use your object snaps.
Come down to the endpoint snap,
left click on the endpoint snap
and then enter to finish your line command.
Notice there, just before I press enter though
I can't go off diagonally anywhere.
I can only go vertically or horizontally.
If I go diagonally, there's no line.
I'll just press enter
to finish the line command anyway now.
So you see how Polar and Ortho tie you in
to different constraints.
The Ortho is very rigid,
you can't get out of it,
it's vertical or horizontal lines only.
That's it.
What you can do though, is if you go back to Polar
which is the one that I suggest you use
this one polar tracking, you can change the increments
of the angles to recognize values.
So instead of increments of 90 degrees
I could use 45 degrees and so on.
These are recognized settings.
If I go to tracking settings at the bottom
I can also switch polar tracking on or off.
I can change the increment angle there as well.
There's the angles there.
And I can also add additional specific angles if I wanted to
in this by box here by clicking on new, as you can see
I can create another angle there if I want to.
So polar tracking can also be set in the dialogue box
like that as well If you want to.
You can also change things like the tracking settings
and the polar angle measurement.
Leave those as they are for now because you don't want to
kind of change settings
and then get a little bit lost later on.
So click on okay.
And that's using polar and ortho in your AutoCAD drawings.
