- [Instructor] Once again, we're staying
in our drawing accurately.dwg file.
And as you can see, I'm zoomed in on the rectangle
that we created in the previous video, this one here.
So it's these four lines here.
What I'd like you to do is select them all,
just click on each line like we've done previously,
and it's a right click after you've selected them
and erase on the short come menu.
That'll get rid of the rectangle that we created
in the last video.
We're going to recreate that rectangle one more time,
using a clever tool in AutoCAD called Direct Distance Entry
or DDE for short.
This time though we're going to utilize our drafting settings.
Now I've saved the best till last
because normally you'd have your drafting settings on
all the time anyway.
So we're going to go down to the status bar,
we're going to make sure that polar tracking is on,
this one here,
Looks like a little slice cut out of a pie,
and then click on the arrow next to it
and make sure that you are using 90 degree angle increments,
that one there.
So where it says 90, it should be tick next to the 90.
If it's next to the 45, like that,
you want to go up to the 90 and click on the 90, like that.
Moving along, you want to make sure that this one
that looks like a little angle, object, snap tracking is on
and then moving to the right again, you want this one on
which is your object snaps, really important.
So your object snaps need to go on.
And then you click on the arrow there next to object snaps.
You want to make sure that these five object snaps are on,
endpoint, midpoint, center, intersection and extension.
Make sure that those five are on all the time
when your object snaps are on.
You'll find that out later
when we start working with object snaps more,
but just make sure that they're on now,
ready to start drafting later.
And then we click on the little arrow
next to the object snaps icon again
and that obviously turns it off and closes the menu.
So we've got, grid on,
we've also got dynamic input on,
we've got polar tracking on at 90 degree,
object snap tracking is on
and we've also got our object snaps on.
Now, the reason we've got all of those on
is they are drafting settings
that allow us to draft and draw accurately.
So we're going to go back to the line command,
come into the drawing area,
and we're back to the specify first point prompt
on the dynamic input.
So I'm going to type in 2000 again, comma 2000 again like that
press enter,
and your line should start from that point there.
Now we are not going to use
the dynamic input way of entering the angles this time,
we're going to utilize our polar tracking.
So if I now draw egg horizontally to the right
with my mouse, can you see when I get the line flat,
it goes green, with that green dash line there
that's your polar tracking kicking in
an increment of 90 degrees.
In this case, you moving into the right,
so it's zero degrees.
So all I've got to worry about is the distance.
That's the dynamic distance entry,
that's it there, or direct distance entry.
It doesn't really matter cause you're using
dynamic input as well
so, it could be dynamic distance entry as well
but it's actually direct distance entry in this case.
So in the going to type in 500,
the angle is already sorted for me with the polar tracking,
so I just press enter.
And there's my first line, 500 long at zero degrees.
I then drag vertically upwards,
and can you see, I get a polar tracking line
going vertically upwards at 90 degrees
and it's telling me that with the little polar prompt
I then type in 250 and press enter.
Don't need to worry about the angle,
polar trackings got that for me.
And then I drag to the left same process, same workflow,
you can see I'm going across now to the left at 180
I type in 500 in the box,
the angle is covered by the polar tracking, press enter,
and then all I've got to do is a right click
close back to the point I started from.
Now obviously if you draw those line segments individually
at different times,
you might not be able to right click and close.
You might need to draw
another left hand vertical line segment.
But you can see how quick and easy it is
when you've got your drafting setting switched on.
So things like dynamic input, polar tracking,
object snap tracking, object snaps,
they all make for a much easier and much quicker
drafting and drawing experience in AutoCAD.
So from now on, down on the status bar, you want to make sure
that dynamic input is on, polar tracking is on,
object snap tracking is on, and your object snaps are on.
You'll find your drafting is so much easier that way.
Now we don't actually need the grid anymore
because we're not snapping to the grid.
So ideally you could turn the grid off if you wanted to
like so, and you can see there now
that you've got a plain background that you can work with
while you're drawing accurately in AutoCAD.
