- [Instructor] Once Again,
we're staying in our ground floor plan
and you'll notice I've done a Zoom Extents,
and zoomed out to the extent of the visible draw objects
in this particular instance.
The reason I've done that is I want us to start working
on some sensible drafting tools
that are going to start helping us enhance our drawing.
These are going to be things like lines, arcs and circles.
Now we've touched on circles a little bit already.
What I want to do is make sure
that when we draw some lines, arcs and circles,
you're aware of the workflows that you need
to generate that geometry in your AutoCAD drawings.
Now, what we're going to do is lines first.
Now we're going to create a landscaped area over here
to the right of the building,
just using some lines in AutoCAD.
We want to make sure that we're on the right layer though.
Always get on the right layer first time,
it's just easier.
So we're going to go to the Layers panel
and click on the Layer fly out menu here like so.
And as you come down the list,
you'll notice there's one here
that ends with the word Site, S-I-T-E.
So if you slide up and down,
you can use the wheel to slide up and down,
come down towards the bottom,
and it's this one here, L-910 M_SITE.
Click there, that is going to be your drafting layer
for the next part of this particular video.
So we're staying in the round floor plan drawing
and we're adding to it as we go.
We're going to zoom in on this area here, so zoom in a bit,
and you want to be able to see these two grid lines.
That one there, that one there
with the door, sort of in the middle.
And then you need to be able to see the intersections
that you are going to be snapping to as well.
I'll show you how to zoom when you're doing that.
So we're going to use the Line command.
So we're in the home tab on the ribbon draw panel
and just click on the Line command like so.
And this will allow us now
to specify the first point of our line.
Now, if you need to zoom in you just zoom in
near the point you need to zoom in to.
So I get the cross here as near as I can, zoom in a bit,
and you can see there's an intersection of a grid line
and a wall there.
So you want that intersection snap there, left click.
As you come outwards, you're going to come out to the right,
make sure your polar trackings on,
and then just roll back on the whee a couple of notches,
maybe even hold down the wheel and pan a little like that.
And as you come out to the right,
you're using the polar tracking, like so,
you're going to type in 1500, 15,000 millimeters, Enter.
And there's your line there like so.
And then what you're going to do
is you're going to come down here like so,
now this is where you're going to utilize
a little bit of your object snap tracking and polar tracking
because you're going to hover
over the end of this grid line here, don't click on it,
and then just move along like this
and you'll get a vertical intersection.
Can you see that there?
As soon as you get that intersection, it's a left click.
And then you know that that is the intersection
of that top right corner
and the endpoint of the line you just placed.
And then we're going to come in here and again just zoom in,
pan up a little bit,
get to the intersection off the grid line
with the wall there, left click,
and then it's just an Enter to finish.
If you now double click on the wheel to Zoom Extents,
you'll see it's a slightly different orientation
because it's zooming to the extent
of the visible drawn objects.
And you've just placed your landscaped area here
out to the right of the building.
So that's our lines that we're working on.
We're going to look at arcs next.
So we're going to go back up to the Layer drop down
and you want to look for a layer that ends in FFE.
It's about halfway down here, there you go,
and you want A-700 M_FFE, that's the layer you need.
So just click on that one, that's our furniture layer.
We're going to zoom in on this table we created here,
the one with the four lines. So zoom in on that one.
Get yourself in nice and close like that.
We're going to look at arcs and how we place arcs in AutoCAD.
Now, we're going to go up to the draw panel
and click on the fly up for arc.
There's lots of different arcs available in AutoCAD
as you can see.
I'm not going to go into every single one of them,
I could probably do an entire course
on all the different types of arcs.
We're going to use this one here,
second one down, Start Center End,
but you can see they all follow a theme.
Start Center Angle, Start Center Length,
Start End Angle, Start End Direction and so on.
So what you're doing
is you're picking particular points of the arc
and then adding additional information.
So Start Center End is simply three object snaps.
So we're going to use Start Center End,
and come into the drawing area, start point of the arc
is going to be the top right endpoint snap, left click.
And then as I come down,
I'm going to go for the midpoint snap as the center,
left click, and then when I come down here,
you can see that the arc is going the wrong way,
I want it the other side.
So if I hold down the Ctrl key
before I click on that last point, it flips the arc for me.
So hold down the Ctrl key,
left click on that last endpoint snap,
and there's my arc in place.
Now, the reason it's done that
is I was placing that arc going from here around to here,
which is clockwise in a negative direction.
So I needed to flip the arc using the control key
to the other direction.
Very quick and easy to do.
Use that CTRL key, it's very handy.
I'm going to do another arc now.
Now I've just drawn one arc,
but if I write click now, I can repeat my arc if I want to.
So Repeat ARC, like so.
This time, the start point of the arc
is going to be up at the top end point here, left click.
Midpoint going halfway down, left click.
And as I come down again, there's no arc.
Why is that?
Because I'm not using the right arc method.
Just hit Escape there before you place the arc.
The reason being is what it does is when you right click
or repeat a command, it's actually using this arc here,
the 3 Point arc, that's the default.
So be aware when you're repeating the arc command,
it goes to that one not the one you may need,
which is Start Center End.
So I'm going to go to Start Center End off of the ribbon again
like we did for the first one.
And then I'm going to start at this end point here, left click,
midpoint here, left click,
and there's the end of my arc on the endpoint snap,
left click.
What we've done now is we've created a nice table
with curved ends with an arc at each end.
So what we're going to do now
is we're now going to remove these two lines,
we don't need them anymore.
Click on the lines, right click and erase.
And then what we're going to do
is a bit of object snap tracking to place a circle
like we did on the other table that we created.
So again, over to the draw panel, click on the Circle,
this time we're going to do a Center Diameter Circle.
So there's Center Diameter there.
There's other circles; 2 Point, 3 Point,
Ten Ten Radius and Ten Ten Ten.
I'll let you investigate those at your leisure.
We're going to use Center Diameter.
Now we need the center point for the circle.
Now it's not a closed boundary
because it's just two lines and two arcs.
So I cannot use geometric center in this case.
What I'm going to do
is I'm going to use a little bit of object snap tracking.
So I'm going to hover over that midpoint there of the arc,
I'm then going to hover over that midpoint there of the line.
And as I come down, my object snap tracking kicks in,
there we go, left click,
I want to see the two green dash lines intersect,
there's the center of the table.
Now it's asking for a diameter
and we're going to go for a 1300 diameter, like so,
Enter to finish,
and there's our nice inlay in the center of our table
using a circle.
So we've done lines and arcs and circles.
Let's do one more circle, let's zoom out slightly.
And what we're going to do
is we're going to use a Two Point circle.
So this is almost free hand.
It's quite clever how this works though,
I really like the way this works in AutoCAD.
So what I'm going to do
is I'm going to go up to the circle flyer again
on the draw panel, and select Two Point like so.
And as I come into the drawing area now,
it's asking for the first endpoint of the circle's diameter.
So I can literally click, and as I drag, can you see?
I'm getting an angle there and a distance.
Now I'm not worried about the actual angle,
what I'm worried about is the distance,
I want it to be 2000.
So I type in 2123, that's the diameter.
So it's basically placing a second point 200 units away
from the first point, at that 26.0893 angle.
I just press Enter and there's my circle there.
Now, how do I know that that is 2000?
I can select circle, I can right click,
on the shortcut menu, select Properties,
that'll bring up the properties pallet,
and there's the diameter of my circle right there, 2000.
I'll close the properties pallet by clicking on the cross,
hit Escape to deselect the circle.
So what we've got now, if we double click on the wheel,
is a group of objects that we've created
using lines, arcs and circles.
We're starting to add to the geometry of our floor plan.
So there's our layout there for the landscaping area,
with the green lines, that was our lines.
We've got some marks here, as you can see,
and we've also got some circles there as well
into the mix as well.
So we've got some furniture now
and what we're going to do is in the next video,
we're going to look at some other ways
of working with other geometry in AutoCAD.
