Create and assign roof types

00:03

Looking at the model,

00:04

we'll create a new roof type for the main pitched roof on the building

00:09

will also swap the flat roof at the front

00:11

for an existing type that's already been created.

00:15

So we'll start by creating a new roof type.

00:18

So first, I'll select the main roof.

00:21

Now, looking at the type selector at the top of the properties pallet,

00:24

we can see that this is the generic 12 inch roof type

00:28

and to create a new roof type, we'll click the edit type button

00:32

to access the type parameters of this generic 12 inch roof.

00:37

And now at the top of the type parameters box,

00:39

we'll click duplicate to create the new type

00:43

and we'll name this one

00:44

wood rafter 10 inch slate tiles.

00:51

Then we'll click OK to save that name and a new type will be created.

00:56

Now, we need to edit the layers of the roof type.

00:59

So from the type parameters on the construction panel here,

01:02

we'll click the edit button next to the structure parameter

01:05

to access the edit assembly settings.

01:09

So in here, we can see we have the existing layer,

01:11

the 1 ft thick layer that makes up our generic 12 inch wall.

01:15

Before we make any changes,

01:17

we'll click on the preview button at the bottom left here as this will

01:20

make it easier for us to see those extra layers being added in.

01:25

First, we'll edit the existing layer

01:27

so we'll change its material. It's currently set to be by category.

01:31

So we'll click on here.

01:33

And now from the button that appears,

01:35

we'll click this to open up the material browser

01:39

at the top of the material browser here, we'll search for the term rafter

01:44

and then from the materials in the search results,

01:47

we'll select the structure with Joyce rafter with bat insulation.

01:52

Then we'll click. OK.

01:54

And then this will be assigned onto our first layer.

01:58

Next, we'll change the thickness.

01:59

So in the thickness column here, we'll change this to be 10 inches.

02:04

And now we're ready to add in the extra layers.

02:07

So we'll add two layers and at the bottom of the layer box here,

02:10

we'll click the insert button twice to add those two layers in.

02:15

And now we'll move those into the right position.

02:17

So I'll select the core boundary at layer one

02:20

and then we'll click the down button twice so that the two

02:23

new layers that we've added are now above the core boundary.

02:28

Now we need to edit our two new layers

02:30

to assign them the correct material and thickness.

02:33

So we'll start with layer one and we'll assign on the material.

02:36

So again, we'll click by category

02:38

and then open the material browser from the button that appears

02:43

in the search box at the top. We'll search for a roof

02:48

and then from the search results here,

02:49

we may need to scroll down a little bit but we can see the roof in slate material.

02:54

So we'll select this.

02:56

And now looking at its properties here on the graphics tab,

02:59

we can see that it doesn't have a foreground surface pattern applied.

03:04

So we'll apply one.

03:05

We'll click on where it says none.

03:08

And this will open up the fill patterns, dialer box.

03:11

And at the top here in the pattern type panel, we'll change it from draft into model.

03:16

And now we search for slate

03:20

and we can see now that we have this slate tiles fill pattern.

03:22

So we'll select this and say, OK to assign this on to the

03:26

foreground surface pattern.

03:29

And then we'll click OK again to assign this material onto the layer.

03:35

The next we change the thickness of the roofing slate layer

03:38

to be an inch and a half thick.

03:43

And now we can see that layer in the preview.

03:47

So we'll apply the material to the layer below.

03:49

And this is gonna be for the timber buttons that support the slates. So

03:54

we'll click on by category again

03:56

and then open up the material browser from the button that appears.

04:01

And now actually just beneath the roof and slate material that we've got selected,

04:05

we can see, we have softwood lumber.

04:06

So we'll select this one.

04:09

And now looking at its graphic properties here,

04:12

we want to add in a foreground cut pattern.

04:15

As we can see, there is none applied.

04:17

So we'll select none next to the pattern.

04:20

And then once the fill patterns opens up, we'll come and search for wood

04:25

and then we'll choose the wood one fill pattern

04:28

and then click OK

04:30

to assign this onto the foreground, cut fill pattern.

04:35

So now we'll click, OK to assign this material onto our layer.

04:40

And next, we'll change the thickness to be an inch and a quarter.

04:43

And then we can see that layer up here in the preview. Now,

04:47

now, finally, we just need to change the function.

04:49

So we'll set the timber patterns here to be a substrate

04:54

and then we'll set the slate tiles to be the finish four function.

04:60

And that's what we need to do in here.

05:01

So we'll click, OK to save the changes to the assembly

05:04

and then we'll click, OK again, to save the changes to the roof type.

05:08

And now we can see that that's been applied to

05:10

the roof that we had selected when we started the process

05:14

and zooming in a little here,

05:15

we can see the foreground surface pattern that we apply to the slate material.

05:21

Now, we just need to change the flat roof. So first, I'll select this

05:27

and now looking at the top of the properties palette,

05:29

we can see it's the generic nine inch roof here

05:32

and clicking on the type selector.

05:34

We can see we have various roofs available to us, including the one we just created.

05:39

We'll select the wood joist eight inch epdm membrane insulated type

05:45

and we can see that update in the model

05:47

and that completes the work we need to do to our roots.
