Create a hip roof

00:04

We'll begin by opening an existing project from the recent files page

00:08

and we'll all bit the model using the wheel mouse and the shift key

00:13

to see the rear of the building.

00:18

We're going to create a roof over the extension here

00:21

using the roof by footprint method.

00:24

So from the project browser,

00:26

we'll double click on the floor plan level two to open it

00:33

using the wheel mouse will zoom and pan over the extension.

00:39

I think. So

00:40

within the architecture tab build panel,

00:43

we'll click on the roof, fly out

00:46

and click on the roof by footprint tool.

00:49

We are now in sketch mode.

00:51

We are currently as we can see within the draw panel using the pick walls tool.

00:56

And this will create a parametric relationship

00:59

between the walls and the roof itself

01:03

over here on the options bar within the overhang field,

01:06

we're going to change that value to two ft

01:11

and then we're going to click in an empty space within the graphics area.

01:15

Before we start adding boundary lines,

01:17

we're gonna go back up to the options bar

01:20

and check the check box for defined slopes.

01:24

We'll now hover our cursor over the left hand wall

01:27

until we see a blue dash line on the outside,

01:29

towards the left

01:30

and click.

01:32

And we'll do that for the upper wall, horizontal wall

01:35

and the right

01:36

hand vertical wall. Also,

01:39

we now need to close this loop

01:41

with a line,

01:43

but that line is not gonna have a slope.

01:45

So we go back up to the options bar. And this time uncheck the defined slopes check box

01:51

and within the draw panel

01:53

over here,

01:54

we'll click online

01:57

and connect the two ends of these vertical lines

01:60

so that we've now created

02:02

a closed loop

02:03

within the properties pallett dimensions section.

02:06

We're going to change the slope value

02:09

to be six

02:11

by 12 instead of nine by 12,

02:15

we'll now select the green tick to finish edit

02:18

mode within the mode panel on the contextual ribbon.

02:22

And we'll see that we've actually created the roof

02:25

and because of the view range clipping,

02:27

we're not actually seeing the top of the roof.

02:29

We're not going to change that.

02:31

If we now go to the 3D view,

02:34

we can see once again, the roof has indeed been created,

02:37

but it's actually embedded into this wall here

02:41

from the contextual ribbon

02:43

geometry panel.

02:45

We're now going to choose the join uno

02:47

roof to.

02:50

And the first thing we need to do

02:51

is select the front edge of the roof that's there

02:56

and then select the edge of the wall that we want to join it to.

03:00

And that has now completed that part of the task

03:04

when we create roofs, using the roof by footprint method.

03:07

When certain things are in place,

03:09

we will be asked if we want to attach the walls to the roof.

03:13

We weren't on this occasion.

03:14

So we will manually make this happen.

03:17

We'll begin by clicking these three walls, which are part of the extension.

03:21

So we'll select the first wall,

03:23

hold the control key down

03:25

and select the other two walls. So that wall there

03:29

and the fire wall,

03:31

and then we will go up to the contextual ribbon

03:34

and click on the attached top base tool within the modify panel

03:40

and click on the roof

03:42

and that will now join those walls to that roof.

03:46

We'll click in an empty space to deselect those walls

03:49

and then we will left click on the

03:52

roof

03:53

and within the properties pallet constraint section,

03:57

we change the base offset from level to two ft.

04:02

And when we move our cursor back into the graphics view,

04:05

we can see that the roof raised

04:08

and the walls heightened.

04:10

So if we undo that,

04:12

we'll see what it was

04:14

and if I redo it,

04:15

you'll see what it became.

04:17

So I'm gonna undo it once more

04:19

and leave it as it was.
