Okay, so in this part two of our
presentations on how to draw a roof plan I'll show you how to take the
plan view that we did before and turn it into our elevations
So let's have a quick look the rules again. Main rule that is going to worry us this time is that a ridge
always has to be level
another thing you need to remember is when we're doing these elevations. I've already put some base lines on these drawings
we're gonna assume that we're standing at this side of the Roof and
what we see on this side of the roof is what we're going to draw on our base line on this side and
Similarly here. we're gonna look this way and protect what we see from here up onto this base line, so
so with that out of the road I'll just make some room
and it will get started okay, so first thing we need to do
I'm gonna produce this elevation, just going to project all the main points of the roof
up onto the baseline, so the outside of the roof
the actual, where the hips meet the ridge
and the other side of the roof develop them all up
While I'm doing that I may as well so this direction as well
Okay, so we project them out onto our baselines so we know where they
where they line up the next thing we need to know is
the actual
pitch of our roof
plus we have to draw in that angle, so this is case I'm gonna use 30 degrees
so that lines at 30 degrees
and I'll start with this hip here it starts there, so I'm just going to put that angle in there and
So we go up the hip what we find we've got our ridge
up to there
we can draw in our ridge remembering all ridges are level and our ridge comes along and it ends on that line there and
pretty simple to see now that
all we have to do is now go from there back down to our
baseline and
fill it in on the other side and we've got every shape
For that elevation. It's a fairly simple
process
Let's just have a look at the other end down so remember looking from this side outside
we've got our ridge line with the other side, so
once again, we need our
Roof pitch
30 degrees in my case
They're lined up where the hip meets the baseline
So when hips going to come up from the base line to the Ridge
There and obviously it's going to go back down
on the other side
Okay, so there you go that's the basic
process of developing our
elevations from our Roof plan
Let's move over and have a look at their more complicated example
Exactly the same process
Remembering and if were going to do this one
Do this elevation we know we're looking from this side, so we want to make sure you get all the points
that we could see from this side, so
Let's do
Okay, so get that one you know ridge line there
Okay, pick up that ridge line or that intersection there. We've got outside of the wall there
Outside of that wall there
end of the Ridge there
Ridgeline there and the outside that wall there
Okay, so we need now Roof pitch
and I'll move that one over so I've got this ridge this hip coming up here, so
then if I look down the roof I've got a ridge line running back there, and then this one is heading down
to a valley okay, so that means I need to have my angle
Going the other way
so 30 degrees in that direction
move that over there, and I'll join that at the ridge in a section, so that's the region of section
30 degrees going back down there, so I get to here I've got a ridge running along there
So I can draw
from their level
Ridge running all the way across to that
point there
And then from there once again I've got a
hip running down
to a valley so I need
my 30 degree line again
running from that Ridge down to that ridge line there, so
I'm down to there and on this end I'm gonna see you hip running down and a Hip running down there, so
and that Hip runs down to that point there
and we're Gonna have
It running all the way through there back on this end we're gonna see
Hip running from there today another one back down
to there
Okay, so we got that hip end here
It's that one
That HIp end there is that on the roof in between
represented by that, great, alright, Let's go the other way
So I need that
need that ridge intersection
that Ridge that
Ridge
make sure get that wall as well, get that point
and
that as well fairly complicated in here remember we're looking from its direction
So let's start with this side. We're gonna end up with a
shape like that, so
We'll get our 30 degree line again
so that comes
up to the Ridge point there, and then it goes back
down
to this valley
which is going to be here, so
Let's get ourselves a 30-degree line going the other way
okay, so that's
It comes down till we hit that ridge there
Ridges goes level of course
It goes along to that point there, which is in line with that
you know we still line, so I need to put
another line in there
and then I can just draw that
Straight down to there
might as well fill this in while i'm at it, that one up to there that one up to there
Okay, so that gives us
The shape of this roof but because this side is bigger, and it extends a little bit further out here we're gonna see that as well, so
we need to then
skip this
30 degree line
It's gonna start on the baseline at this point
It comes up to where the Ridge meets
now we have a
Horizontal Line going
right across until we hit
That part there so that one there
Okay, and then the line actually goes back down
to the valley so it's gonna have back down at that point. So that's all we're gonna see
now you can fill this end in here as well
clean all this up, so that's what our elevations gonna look like at that one
They can see exactly the same process a little bit more confusing, but just follow the process remember the rules
Then the shape will coming out
Okay, so just to finish it off let's have a look at our last shape, the one with the oblique end on it
exactaly the same process just
develop their lines up
Okay, you know made that point there a point there. Need this one especially important
Okay, now with an oblique end because these angles won't end up being 30 degrees
Little bit hard to start with oh, so I'm going to start at this end
With a 30 degree line or our roof pitch, whatever
angle that happens to be
Okay, so start, remembering we are going for this Hip here put that under there
Okay, so it comes up
and hits
the Ridge there
and then it goes back down to
a valley so I made
the angle going the other way
Okay, so I'll put that on the ridge line
that comes back down to the Valley
and the Ridge starts at this point there
and it goes level across to that point there
Right so let's fill the rest of this end in
up to there, back down to there
Okay, now with our a oblique end and again. I forgot to put in a development line I need one there
Alright, This is where a heap in our Ridge ends and
our
Hip hit's the outside the wall here and the other one. It's here so all we have to do
It's from the end of our ridge draw a line down to that point
another line down to that point
And that'll give us the shape of your roof. I've also got a fill in
That one there
Alright, so let's clean that up
Okay, so let's do a quick check
Yeah, I can see that into the Roof I
Can see that part of the roof and I can see
an oblique end on that way so that one's okay
Alright, let's just go the other way
No major points make sure I get that
30 degree line to kick us off
Now once again I'm gonna start away from the oblique end of this hip down here. It'll go in there like that
and it meets the ridge there runs up till it hits the ridge
Then this goes back down to a valley
Ridge down
Okay, and then once again similar to what we did on
this side
What we're going to do from here is take these
down to our
baseline
and that'll give us a
true representation of
the Oblique end
Okay, so let's do a check again
Looking this way, I can see that there, I can see this side there
That's all I can see this so that's a oblique end done
So that's it, that's how we develop our
plan view and
our elevation, so you can see the position of our hips ridges broken hips and their valleys
