Hey, what is up, nation?
In this session I'm gonna be teaching you
how you can cut a hole through a cylinder in Sketchup.
So I've modeled a cylinder here.
Pretty simple, just make a circle.
And then push-pull it up.
And I'm not exactly sure what you're trying to do here,
but I'm just gonna really quickly make a cylinder here.
So I chose the offset tool.
And then offset that edge.
Then I'm gonna push-pull this down.
So if you wanted to just make a tube,
that's how you would do that.
But I'm assuming that most of you probably want
to cut a hole through the side of the cylinder,
or any curved object.
And to do that, you need to make an additional cylinder.
That's gonna cut through this.
So what I just did, is I turned on the hidden geometry.
Just go to view -> hidden geometry,
and that's gonna allow you to see all these little lines.
So if you're not familiar with SketchUp,
everything is basically just a bunch of lines
that make up shape.
So the cylinder looks like a circle.
But is actually a faceted shape.
So whatever how many, I think 16 size is the default.
So whatever as 16-sided shape is called,
that's what that is.
You can see here, that these little segments here
are connected by these hidden lines.
And then the hidden line source are smooth.
To give the illusion of something spherical or curved.
And so in this particular case it's important
to just sort of understand that these are flat planes.
That are sort of masked.
Not look like flat planes.
So when you're making your circle,
it's helpful just to know that.
So if you do a circle that goes between these,
it's gonna make it hard.
And you can sort of get a circle,
that is parallel with this face.
By just drawing on that face.
So I'm gonna do that.
And you can see here, it understands.
This is being part of the shape, but not this guy.
Because they're separate.
So actually just gonna take this.
I'm gonna move it off.
We're gonna go. Hopefully in this direction.
Unfortunately, I can't get like gay.
Just have it.
There we go! There we go!
We want that perpendicular axis, there we go!
So just come out here.
I'm just gonna erase these guys.
So you can see it looks normal now.
Now this is no longer a shape.
So to make it a shape, you just take
one of those segments.
You can see here. Just finish it.
And it's gonna redraw that shape.
Now there's two ways that you can sort of go about this.
And I'm going to show you both ways.
Just because it may make a difference,
depending on what you're doing.
Most of the time I feel like it's a preference.
So the first way we're gonna do,
is we're gonna triple-click all of this.
And make it a group.
And then we're gonna double-click this,
and make that a group.
So you just double-click there.
And then right-click to bring up that little menu.
And then I'm gonna select this.
By just triple-clicking into this group.
Hit P for push-pull.
And go all the way through.
Okay, so we have two groups.
And they should be solid.
If for some reason this has like a bottom,
this next thing I'm going to show you won't work.
And it'll it could take you a while to fix it.
So that's all.
I'll show you the second way after this.
So what you want to pull up now,
is you just-right click in an open space.
It'll give you this menu. Of all the menus.
You wanna make sure that you have the solid tools selected.
It'll bring up this little menu here.
Solid tools there is something called "subtract".
So it says "Subtract first solid from second,
and keep only the result in the model".
So subtract the first from the second.
So we would want to select our tube, and this guy.
And if you're getting that, you see the cursor has a little two.
That sort of is saying "Yeah I understand that these are two solids".
And unless you perform that operation.
Now if I turn off hidden geometry,
you can see that I have a hole through that.
Now just to demonstrate.
If for some reason that wasn't there, well,
if I was to try to do this and do subtract,
it won't let you select that second shape.
So that's to be a completely closed off shape.
So for instance, let's say, that was the case.
What I would do, is I would probably explode this.
So that this is just sort of hanging out.
Alternatively, you could copy this group into that other group.
But what I'm going to do,
is I'm going to select all of this.
And then select this as well.
Right-click, and go to intersect faces with selection.
What that's going to do, is going to essentially
make these little lines, go-through.
Now if I delete that, you can see I have this little face here.
And if I select this, you can see that I get this.
So the hole in the middle here is, you can see it.
If you want sort of that center piece here,
what you would do is we're gonna explode this.
And then I'm gonna explode this as well.
Then just select that whole tube.
But I'm gonna reverse this face.
Now the reason that I'm reversing this face
is because it's essentially going to become the inside here.
So when you look at it from the side,
it'll be the correct way.
There's just sort of planning ahead here.
So I'm just gonna select everything, right-click.
Go to intersect faces with selection.
They can see there's some lines here now.
So what you need to do,
is you can actually just delete these extra things.
I'm just gonna delete those.
Select this.
And you can see that I have that inner,
which is a part of what the tube was before.
That's why we had to reverse that face.
So we would get this instead of this.
Just going a step ahead.
So yeah, a couple ways that you can make cuts in your cylinders.
Hopefully this helped.
