Welcome to different selection methods.
So in this video we're going to learn some more ways to select your geometry using two features border
select and circle select.
So let's hop over into blender.
Now both of these features are located in the select menu on the 3d Ed header so under select We can
see you've got circle select and border select.
Now you may hear me refer to a box select which is exactly the same thing as border select.
You're essentially during a box or a border around the things you wish to select.
So you do need to be in edit mode if you're not already and you do need to choose what you're going
to select just like you would do if you're selecting things individually whether they be edges faces
or vertices.
So if we hit the big key.
Let's see what happens.
So we've got it on edge select and we're going to draw a box around here so selected.
Every edge that line came in contact with.
And if we spin round we'll see that it's not selected anything on the other side.
If you do want to select through an object say this the whole top of this pyramid I would suggest you
first move your view around so you can select the box orthographic view is best so there's no perspective
playing.
You want to d select.
You've already selected and you can just press a key which D selects as well as selecting all hit the
beaky for box select.
And before you do that.
You'll want to go in to wireframe mode.
Rotate it back down in wireframe mode when you use a selection tool.
It selects through your objet So I'm cautious now about how I'm selecting.
That should have selected everything on top.
Do you have to be careful if I drag the box round the actual too far out of selected all the top of
the pyramid as well.
Now in this view you'll notice if I finger and box select that edge it adds to the selection.
If you want to remove from the selection when you do in the box selecting you can middle click.
So a middle click and drag all d select.
A.
Just clicking and selecting more will add to your selection with no further impact.
So let's try out Circle select circle select produces a circle and you can change the size of that circle
with your scroll wheel.
So obviously if it's this big and we've got it on edge select as we go over.
Umm clicking now you can see I am selecting loads of edges as we go and as soon as we see this one here
soon as all four edges of a face or however many face edges the face has have been selected the face
highlights as well.
So if I select that edge there it adds to its And again middle clicking will select as you go so you
can select and select two using both of these selection tools.
Very powerful stuff especially since we can change the size of this circle.
Finally you can do anything.
Steve exited the circle so you do need a right click at some point to exit.
Whereas the box select automatically exits at the end of the selection.
I found a challenge.
Okay guys.
I'd like you to remove some of the pyramid using either border or circle select.
I'd like you to remove the parts of the pyramid covering the ramp that we've made ready for the stairs.
So a quick look here at the pyramid how it is at the moment and then using the various selection methods
we need to get to something that looks a bit more like this.
So here we go.
This is what we're aiming for those faces removed so we can see the ramp underneath.
Now there are various ways you're going to be able to accomplish this you could do it one at a time.
But I do suggest that you use one of the quick selection methods so you can highlight the lot and work
on it.
So examples of video now and give That's a go.
Welcome back.
Let's go and remove those parts of the pyramid.
So let's hop straight on over into blender.
Now we can see quite clearly.
Oh we can't actually because this pyramid's the same on both sides and I've rotated it round several
times so I can't see clearly one of these has got a ramp rep.
And one of them hasn't.
How do we tell that well we're going to hop over in to wireframe mode.
I'm going to move it back into perspective.
And I'm just going to remove all the rest of the orange so we can see there that there's no ramp on
this side and there is on here.
So now we know that we can come out of wireframe mode.
Now the ramp itself I'm being a bit forward thinking here the ramp itself stops on the edge so we don't
want to delete that edge.
Otherwise the ramp itself will disappear.
So we need to delete that hedge all the way down to that edge.
We could hold down Shift and select them all.
There's not a great number in this case.
I'm going to because I'm at an angle I could make it perfectly square and use board border select but
because I'm at an angle I'm going to hit see four circle select doesn't have to be terribly big.
I'm just drawing straight up here all the way to there.
Finally I'm.
I can even go through mesh punch can I hit the x key.
Ah.
So what the circle selected.
Remember to right click out of it.
Okay x how we're going to delete the edges.
Nothing else just the edges.
And there we go we can see our ramp underneath.
Brilliant.
How did you guys get on.
Remember to save your pyramid if you haven't done already.
And oh I've just had a thought a week or so.
I haven't named my cube.
Was not cube.
Oh dear.
So let's change that now.
So it says pyramid.
And of course that's the mesh object renamed rather than meshed data itself.
But don't worry we'll get to that a bit later in the course to understanding the differences.
But so if any of you have already named your mesh pyramid Congratulations you become a teacher to doing
it.
Make sure you do name your meshes otherwise later on when you have something more complex is going to
be a pain to find anything.
See you guys in the next lecture.
