Welcome to using existing geometry to create new so in this video we're going to use an existing face
to create a new face.
We're going to separate that immediately creating a new object.
And this basically allows us to match up parts of our model even when they're not exact sizes.
So if you had a face that was to blend the units across a quarter you could just create another a start
with a plane.
Let's say you have a square top of a cube you could have a square and just make it the exact size that's
absolutely fine.
In fact you could scale it to match the right size but sometimes you're not going to have these nice
shapes to work with or exact sizes.
So in this case we're going to use an existing face separate immediately and match and that will automatically
match up anyway.
So let's hop straight on over in a blender.
So we have the base we've been working on here and this face in the middle is the one we're going to
work on.
But instead of playing around with this let's learn the techniques we need to do in a new blender fast
from going to go and open up a new file now and will simply work on the default cube.
So we're going to copy this face that's on top is relatively straightforward you've probably already
got it in your mind's eye.
What we're going to do first of all we're going to hop all over into edit mode then select face select
and select this top face.
Now there are loads of ways of duplicating that face.
And all I'm going to do in this case I don't need a link to duplicate.
I just need duplicate.
And if you remember AB That is shift endi will duplicate the face.
Brilliant.
That's now done.
But immediately straightaway after going shift and the end duplicating I'm just going to press enter
to set it where it is so I've not moved it left and right.
If you do need to duplicate.
Otherwise it is under the mesh menu and we've got Where is it on here and duplicate just there.
Put the mesh and move out.
If we don't get any linked duplicates whilst we're in edit mode.
Now once that's there we need to separate it so we still got that face selected so we can hit P and
we can separate by selection.
And now if we just have a look I'm going to turn off the cube itself over here in the outlines.
Hop on over into object men are going to turn it off and so that is the face that we've just copied.
And the cube itself is still there and we should see it with the cube selected.
We can see that it has its Let's go through here six faces.
Yes that's absolutely fine.
We've not duplicated anything within the model itself and we can look up there.
There are eight vertices around there and it's still got eight.
We hop over here.
We should have four vertices.
If we hop into edit mode.
Because I've hidden it I've hidden it guys and I've not noticed that I've hidden Okay so now that that's
there.
We hop over to edit mode in with just that essentially a plane on top.
We've got an exact duplicate and from that of course we can extrude and do things from.
And that's now a completely separate model.
Okay brilliant.
Let's go apply that knowledge over in our lamp base and we're going to do that with a challenge.
Okay so I'd like you to create a stem for the lamp using the face at the bottom of the hole the one
that showed you a few minutes ago and we're going to generate the need geometry and build the stem up
from there.
I do suggest scaling the stem in ever so slightly to create a slight gap around the top of the hole.
So pause a video now and give that a go.
Welcome back.
Let's go complete this challenge over in blender.
So this is where we left off.
And let's hop straight on over and open up our animated lamp.
And here we go we've got the base in front of us and it's these faces here that we want to duplicates
of this area in the middle.
So I'm going to use the circle select tool to do that.
I'm going to clear the selection first.
So there we go.
Press for serpell Select and I can just draw rant and it looks like I don't have face select selected
at the moment so again let's clear that selection face select should have had a bit of a clue with the
dots there.
But see draw around there.
Brilliant So that's all of those faces selected shifta will provide us with a duplicate.
Once we've exited with the right mouse button from CIRCLE select shift the that's produced a duplicate
press enter to set it in place P to separate it and I'm immediately going to rename it over here into
STEM will do for the moment.
Hop on over into edit mode.
Select all of those faces and we can extrude them upwards on the z axis.
Were there a go.
I'm not sure how tall that is at the moment.
In a bit far.
That's absolutely fine.
So the final thing we can do here is literally just scale in ever so slightly.
I'm not going to do it initially.
I'm going to literally draw our border.
Let's hop on over into object Marish draw a border around here and render it so we can see what's going
on.
In fact we need lights on we've got our lights turned off at the moment.
So where is it's in our let's turn our back drop on the lamp on somewhere else.
Minimize this here.
I really ought to put all of my lighting in one area so can find it.
So I've turned the plane on and there seems to be a bit of triangulation going on here.
We can sort that out later on.
Now at the moment if we go to this base area here.
Zoom out a little and there we can see that it's pretty much flush.
Now that's not going to happen in reality.
So with the stem selected I'm just going to grab this top and literally just scale it in.
Now going to be a bit silly here.
So show you what I want to do in fact we may bevel the edge on the edge to make it a little neater and
we want a gap around there but we only want a small gap so let's scale it in by maybe points 9 7.
Let's see.
Yep that's left a nice gap down there and whilst we're talking about just bevelling that edge ramps
it's a little bit smoother.
Let's hop over to our lamp base.
Pop into edit mode.
I'm just going to stop the rendering so I can see what's going on.
Unconfessed selects that edgerley round there.
I'm going to bevell it of course that would be silly.
Owning needs to be a little.
Perhaps something like VAT's hop straight over into rended mode see how that looks much better.
Brilliant.
How did you guys get on.
I'd love to see what you did when you got your stem put in.
Did you have any challenges.
Share in the discussions and I will see you in the next lecture.
