Create a gabled roof

00:04

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

00:10

We're going to construct a gable roof over

00:13

the garage using the roof by footprint method.

00:16

So it's over this building here

00:18

that we're going to create this gable roof from the project browser.

00:23

Double click on the garage roof floor plan

00:27

and then within the view tab

00:30

windows panel, select tile views,

00:35

then using the wheel mouse zoom and pan into the garage in both views.

00:42

So we'll do that in the floor plan and the 3d view

00:46

and make sure that the garage roof floor plan is the focus for you

00:50

from the architecture tab up on the ribbon, click on there

00:54

and within the build panel, click on the roof, fly out

00:58

and click roof by footprint.

01:01

We will now be in sketch mode

01:03

by default. We are creating a boundary

01:06

as the boundary line icon is currently highlighted

01:11

using the pick walls tool. Within the draw panel,

01:14

we are going to draw a closed loop around the footprint of the building

01:18

offset by a distance of two ft.

01:22

So on the options bar within the overhang field, we'll type in two

01:28

and then moving the cursor into the graphics area will left mouse click

01:34

before we create our closed loop. Notice also up on the options bar

01:39

that the defined slope tick box is enabled.

01:44

We're halfway our cursor over one of the existing walls

01:47

until we see a dash line outside the garage building.

01:50

So if we hover our cursor here

01:53

and then hit the tab key once on the keyboard

01:56

and then left mouse click to add the closed loop.

01:59

The two shorter lines, one at the top, the other at the bottom

02:04

are going to form the gable for their roof.

02:07

So we need to remove that slope symbol.

02:09

So click, modify up on the ribbon

02:12

and with the help of the control key, choose the two short lines.

02:15

So we'll click the first one at the top, hold the control key down

02:20

and select the lower of the shorter lines

02:23

and then up on the options bar.

02:25

We will now remove the tick

02:28

within a defined slope check box

02:32

and now select modifier to deselect all lines.

02:36

We can now see two lines with a slope symbol adjacent to them

02:40

and two without,

02:43

we'll adjust the values allocated to the two with a slope symbol from nine inch,

02:50

to six inch by 12 inch.

02:53

So again, with the assistance of the control key,

02:56

we'll click one of those lines,

02:58

hold the control key down, select the other line

03:02

and within the properties pallet

03:04

change the slope value

03:06

to six inches. So we replace the nine with a six

03:11

click in an empty space within the garage roof. Floor plan to deselect the two lines

03:18

from the ribbon. We'll now click the green tick to finish edit mode.

03:24

And in response to the question,

03:26

would you like to attach the highlighted walls to the roof? We'll now click attach,

03:32

click in an empty space to deselect the roof.

03:35

Looking at both views, we can now see the roof has been successfully created

03:40

earlier. We used the pick walls tool to draw the closed loop.

03:44

What this achieved was to create a parametric

03:47

relationship between the roof and the walls.

03:50

If we go down to the view control bar, allocated to this view

03:55

and within the visual styles pop up menu,

03:57

choose wire frame

03:60

and now we can see the walls.

04:02

So if we click and drag any wall, we'll see

04:06

that the roof auto adjusts

04:08

to match the movement of the wall.

04:11

If you go up to the quick axis toolbar and click undo

04:15

and drag another wall, we can see

04:18

that the roof auto adjust

04:21

and once again, we'll click undo

04:23

up on the quick axis toolbar.

04:25

We will now set the visual style back on the view control bar

04:29

to back to hidden line.

04:32

We also constructed the roof within the garage roof floor plan

04:36

which constrained the roof to this level.

04:39

We now got over to the project browser and

04:42

opened the south elevation by double clicking on it

04:46

and make that south elevation of view, the main view.

04:50

And we do that by going up to the view tab up on the ribbon and click on there.

04:55

And within the windows panel, select tab views

04:59

and then zoom in to the garage. So using the wheel will zoom and pan into the garage.

05:06

This level here

05:07

is the garage roof level.

05:10

So if we click on that

05:12

and increase that by a foot, so if we change that to four ft,

05:17

when I hit, enter on the keyboard,

05:19

we can see that both the walls and the roof auto adjusted.

05:23

So if I click on that temporary dimension again

05:26

and change it back to three,

05:28

we can see it returns back to its original level.

05:33

We'll now open the 3D view by clicking on the tab at the top of the graphics view

05:39

and within the quick axis toolbar, we'll select the icon that closes inactive view.

05:44

So we click on close inactive views within the view.

05:48

We will now double click our wheel

05:51

to zoom to fit.
