I'll swap back to rev it now and we'll see how to do this live in the model.

00:09

First, I'll select the screen wall coming down from the top of the view

00:14

and then from the properties pallette,

00:16

we'll choose edit type to access its type properties.

00:20

Then we'll click edit next to the structure parameter to access the wall assembly.

00:26

Looking at the layer list.

00:28

We can see the core boundaries either side of the

00:30

air layers and incorporating in the metal stud layer.

00:34

The air layers need to be moved outside of the core boundary. So

00:38

I'll start by selecting the top air layer layer three

00:43

and then click the up button

00:44

to move it above the core boundary.

00:48

Then we'll select layer five, the lower air layer

00:51

and click the down button to move this one outside of the core boundary.

00:55

And we can see in the preview now the

00:57

green lines indicating the location of the core boundaries,

01:00

either side of the metal stud layer.

01:04

While we're in the world assembly,

01:06

let's change the function and priority of the air and metal stud layers.

01:10

We'll start by changing the upper air layer layer two from

01:14

substrate to thermal air layers with a priority of three.

01:18

We'll repeat this for layer six, the lower air layer.

01:22

And then for the metal stud layer which is layer four,

01:25

this is currently set to structure with a priority of one

01:28

and we'll change it to substrate which has a priority of two.

01:33

Now we'll click OK to save those changes

01:37

and OK once more to apply them to the walls in the model.

01:41

So now we can see that's changed the junction,

01:43

but we need to edit the installation in

01:46

the main external wall to complete the junction.

01:50

So we'll select this main wall.

01:52

And again,

01:52

we'll choose edit type from the properties palette to access its type properties

01:58

and then click edit next to the structure

01:60

parameter to access the assembly settings again.

02:03

So here we can see the insulation layer is outside of the core boundary

02:07

but needs to be within those core boundaries to give us the correct junction.

02:11

So this time I'll select the upper core boundary layer which is layer four

02:16

and click the up button to move it above the installation.

02:21

And now we can see it's within the core boundary along with the cmu layer.

02:25

So now we just need to change the function of the insulation layer

02:29

and we'll change this from being thermal layer layer or a priority of three

02:33

to a substrate with priority of two.

02:36

So this should now give us the junction that we need.

02:39

So we'll click, OK,

02:40

to save those changes and OK to apply them to the walls in the model.

02:45

And now we can see we had the junction that we wanted

02:47

with the metal stud layer of the screen wall meeting the insulation layer

02:52

and with the air layers of both walls having

02:54

emerged to be a continuous component around the junction.

02:58

An alternative scenario

02:60

would be if the screen wall was built after the external wall.

03:03

And therefore,

03:04

we didn't want the components in the core boundaries to interact

03:08

or to create any kind of joint between the walls.

03:11

And we just wanted the screen wall to finish

03:13

against the granite panel of the existing external wall.

03:18

So to achieve this,

03:19

we would need to stop the walls from creating a joint

03:23

to show how to do this. I'll select the current screen wall that's got the join

03:27

and we'll make a copy of it. So

03:30

from the modify ribbon tab, we'll choose copy

03:33

and then click to pick the wall up

03:35

and we'll move it across to the left here and then click to place it down.

03:40

I choose, modify to finish the copy command

03:42

and we can see that it created the same junction

03:45

as it had done previously.

03:48

So to stop this from happening,

03:50

we'll select the wall

03:52

and then hover over the grip at the bottom of the wall where the junction is made.

03:57

And then from the right click menu,

03:59

choose disallow join.

04:02

Now when we deselect the ball,

04:04

we can see that they no longer join

04:07

and the screen wall is just overlapping the existing external

04:10

wall with no attempt being made to create any junction.

04:14

If I reelect the screen wall,

04:16

we can see at the end of the wall,

04:19

we have the symbol here to indicate that the

04:20

joint is disallowed for this end of the wall.

04:23

And we could click this symbol to re allow the join.

04:27

However,

04:28

we just need to cut the screen back to meet the external wall.

04:32

So to do this from the modify ribbon tab and the modify panel,

04:36

I'll choose trim extends single element

04:39

and then select the edge of the external wall to be the boundary.

04:43

And then we'll choose the side of the screen wall that we want to keep.

04:47

And now we can see that we have that just butted

04:49

up to the external wall without any junction being made.

04:55

So there we can see how the core boundary

04:57

and the function and priority can affect the clean

04:60

up of walls and how different walls can meet

05:03

to create different detailed junctions.
