Hey, what is up, nation?
In this session I'm gonna be teaching you how to make
architectural sections using Sketchup
All right, so I imported this model from the 3D warehouse. There's a link to it
down in the description below. And the first thing that I want to do is just
make sure that my section planes are on. So go to "view" and make sure that section
planes is checked here, and then over here on the right side there's the
section plane tool. If you don't have this toolbar you can just white
right-click in a white space and just make sure that you have...its called large
tool toolset. You just make sure that's checked. And I like to dock mine over on
this left side here. But there's also another place to make a section tool in
the menu...yeah. So under tools, there's also section plane. If you don't want to
make this new toolbar. So just be right back. So a section plan I'm just gonna
click that. I've made some sections before in this model by default. It will
say "Section 1", and then have a symbol. So you can do that in...this is Sketchup 2018 pro.
So that's a feature in this. I don't remember this being in older versions. So
I'm not sure exactly when this was implemented. But it's really helpful. If
you're going to layout eventually. To start thinking about your sections and
how you're naming them. For now I'm just gonna leave this as section 3 symbol 3.
Because I don't want to make it interfere with anything. Now what's gonna
happen, is it's gonna give you the section plane. And you need to place that.
So you can see, it's sort of going all over the place, it's kind of confused.
What it's doing, is it's referencing the planes that I'm mousing over. As the
section plane. Like this green is perpendicular to this axis here, and the
green or the blue is a horizontal plane. And then
red is perpendicular to this axis as well. So this can be a hassle sometimes.
If you want to sort of like click in the middle here. But get it to be on...let's
say, the green axis. Right now it seems like it's doing it okay. Or actually it
just change to white. What you can do, is actually press the arrow keys on your
keyboard, so if you press up, it'll lock to the blue axis. Right - will lock to the
red, and green will lock to...or left well lock to the green axis. Really helpful
tip when you're doing sections, because they can go haywire really quickly. We
are gonna start making a red section through the middle of this. I'm just
gonna click the center point of here. And you can see, I get a really nice section
through the middle. Now I've opened up scenes here. You want to make sure that
if you're doing multiple sections it can get really confusing, really quickly. So I
would recommend opening scenes. So you go to window -> default tray, and then make
sure your scenes tab is selected. And then in your default tray you'll have
this little drop-down bar...hold on a second. Just lost everything. Scenes...there
we go. Let me just delete one of these and I'll make a new one. So let me turn
my section planes back on so I have this guy. I'm gonna hit the plus our arrow to
add a scene. Now you can see down here I have a bunch of stuff checked. The thing
that you want to make sure that is definitely checked for this, is an active
section planes. That's gonna allow you to switch back and forth between what
you're seeing. So right now this is actually deactivated. So I just want to
activate there, just right clicked on my plane. Went to "active cut", and then it
will change that to "inactive cut". So it's really helpful. And then, you know. Pick
your camera view. Maybe helpful, maybe you want to straight on view that I know
that's pretty popular. You just want a standard view. Let's try, right.? Yeah, looks
like it. So, and you can see everything sort of grayed out a little bit.That's
because of the section plane. So...there's a section plane and the
section cut. The cut is the literal cut and then the plane gives sort of like a
hue to everything. So what I like to do is turn off section planes. When I'm
doing this. And then just update my scene. That way I
can see right on and always, when you're doing scenes, just do the due diligence
of giving this a name. So we're gonna say "a short section through bedroom"
Okay, so that's a nice name for that. It's very descript. So, and we could even say
let's click on this again. A short section, maybe even wide 2D. Short 2d
section. Because we may like this, but then I want to add a scene, using this.
Same view. And then go to perspective. So it's very similar but it has more depth
now. And then I'm just gonna update that. So we have this guy. And then we have
this guy. So, you get two different sections. Now the other thing that I
wanted to show you with this, when I have section planes on, is that you can
right-click on your section plane, and go to create group from slice. Now what
that's gonna do, is make a really nice line drawing of the section. It can see
it's kind of wonky here because of the section plane. Actually, I'm not sure
exactly why it's so wonky. It's like strobing...but if you want to import this
into illustrator or CAD, or something, this is a really nice line. Work to
easily bring in. Before you do that, and whenever you do a section, you may want
to consider turning off some of the extra things that you have. Like this bed
is kind of weird to have in a section. To be cutting through
that as well. And the couch and things like that. So, that may be something you
want to put all of your accessories and furniture on a separate layer. Just for
clarity's sake. We just come back in here, rename this. I'm gonna change this to 3D.
Okay. So we have that. And then let's say, we
want to add another one. But we want to have a section plane going in a
different direction. So what I'm gonna do is I'm going to deactivate this cut,
select my section plane again. I'm using the arrow keys here. The left key to get
that green axis. So it's going this way. I don't really see much of the building, so
what I'm gonna do is right-click on this, and hit reverse. It'll change the
direction of my section cut. Again, turn off my section planes. I want a really
nice...I don't want this tree, I went back. I want a really nice perspective drawing.
So I'm just gonna hit back there, and you can say I'm off of the green axis.
Probably I should have set that down. So that it's a quadrant is here. Are part
of my model is actually on the ground plane. But it is what it is at this point.
So I'm gonna update my scene again. And now I can really easily...you can see
there's an animation going. The section is actually changing. This section cut
animates between these two. But I get a really nice section. Through that as well.
So, hopefully this helped. I guess the last thing you can see that animation is
going on between. And that can get really annoying if you're not planning on
actually doing an animation. And depending on how complex your model is
it can slow things down. So check the description below for a link to how to
stop the animation on a video that shows how to do that.
