Hey, what is up nation?
In this session I'm gonna be teaching you how to make an oval dome in Sketchup.
Alright, so there's a question on one of our videos that was
asking: "How to make an oval dome", because we show in a few different videos how to
make domes, so this is actually how to make an oval dome and I started, and I
was like "Yeah, actually this is a is a difficult thing!", so I'm gonna show you
two different ways to do it, the first is kind of like rough way that you can just
get a dome, and then the second is how you get the literal shape of the dome,
but it just takes a little bit more time, so let's say this is our building, right.
And we want to put a dome roof on it. I'm gonna make that a group, and then what
I'm gonna do here is make a sore another circle, and then draw this is like in our
other video, draw some lines here, hit A for arc, choose my two end points, hit
this corner here and hit shift to lock, so that I'm in that axis and if you want
to have a cabal G, sort of dome, you can certainly do that, this would be a little
bulge here I want it to be more round, so I'm just gonna try to eyeball this. Looks
pretty good. Delete this inner circle, select my path,
choose the follow me tool and select the shape.
Okay, I'm gonna reverse the faces here,
I'm gonna also make this a group. Now, place this here, it asks for scale, then
I'm just gonna scale it until it looks generally correct, right, so this this is
what I'm saying it's not exact, but it kind of gets the job done. This back part
is maybe not the best, but you know, you you could then put a parapet or
something around this and it would hide the dome, cuz you're not gonna have a
dome that actually goes right to the edge in most cases, so like maybe it
looks something like that, and that for your purposes might be fine so there's
just making us a regular dome and then stretching it to become an oval and if
you wanted to flatten it out, you can certainly do that. I'm just gonna copy
that over to the side, so we have both versions, and then I'm gonna select that
click into the shape, hit ctrl+C for copy, and then copy this, so now I have that
exact shape. Now I'm going to draw a line through the middle here, I'm just gonna
draw a bunch of lines that connect across this point. Start in the middle
that connect with the midpoint that go through the midpoint, right, these
starting to see what's going on here, a bunch of lines, this is pretty much, this is
pretty much for me, just so that I can see
what is going on, and I don't get too confused. So I have a bunch of these
lines, and then how tall do I want it, let's say this talk, and then you just
start to draw your arcs, so you can see it's in the red axis here so I'm just
gonna hit the up arrow on my keyboard to lock to the blue axis, I get that guy and
then you just do that for all of these. I'm just gonna speed this up and
and then we'll come back after I finished.
Okay, so now we have a bunch of those shapes and I'm gonna delete the inner
portion, I'm just gonna try to select these, not too carefully, but carefully
enough, I just want the inner portions of these shapes gone, okay. So I have a bunch
of these, now I'm gonna select all these lines, go to draw, sandbox from contours
and I now have that shape. And it makes a group automatically, so I can just smooth
this, you can see that I have a shape here that fits right on my building.
And if you wanted to be less or more dome-like, then you can do that. My
thoughts on this dome is that it might not be round enough for you and so I'm
gonna show you a third way that you can do a dome, so we're in three ways out of
this. What I'm gonna do here, is just copy this off to the side, it's actually just
control+C, edit paste in place, and then push pull this up, so that I have another
shape on here, hit M, select that face and then hit M to move, then move it all
the way down, and then hit the forward slash, we're going to do five, so now I
have five instances of that shape through here. Now I'm going to select
this, hit S for scale and then select one of these corners and I'm holding the
ctrl key, so that it scales uniformly in all directions, and then just sort of
massage this, so that it begins to look like what I want. So obviously with an
arc at the very top is the smallest
let's do something like that maybe, and then move this down. So hit the up-arrow,
so that's more dome-like. Now you have these lines here, so if you get easy for
the eraser tool and then ctrl click on each of them, it'll smooth out that line
and hide it, so now I have a dome here, and obviously you can see the facets
that go around, the more lines that you do so I did five in this case, but the
more that you do, the smoother it will look, so hopefully this helped, if you
