INSTRUCTOR: Customizing wall geometry
00:09
is as simple as applying or defining a new wall type.
00:14
The Type Properties dialog contains many settings
00:16
that can be customized to create nearly any imaginable wall
00:19
design.
00:21
Now, currently our model uses only generic walls.
00:24
Now, generic walls just have a single component
00:27
of a designated thickness.
00:29
But by choosing alternate types, we
00:31
can express the construction of the walls
00:34
and their internal materials a little bit more accurately.
00:37
Now, I'm going to do this work in a 3D view.
00:40
So I'm going to go to the Default 3D View icon here.
00:43
I'll roll my wheel a couple clicks just to zoom in a touch,
00:46
and I will highlight this exterior wall here.
00:49
And notice that it's a basic wall, generic 12-inch wall.
00:53
I'm going to select that wall, go to Edit Type,
00:56
and then here in the Type Properties dialog,
00:58
there's an Edit Structure button at the top,
01:01
and I'll edit one more time.
01:02
Notice that there's just the single layer here, layer number
01:05
two, that's set to By Category, which essentially means that it
01:08
doesn't have its own material.
01:10
And its total thickness is 1 foot.
01:14
So that's what we mean by a generic wall.
01:17
So now what we're going to do is we're
01:18
going to select the exterior perimeter of the walls
01:21
and change them to a different wall assembly instead.
01:24
So let's highlight that same exterior wall.
01:27
But this time, before you click, I
01:29
want you to press the Tab key.
01:31
Now, notice that when you press Tab,
01:34
it goes down the lengths of the walls
01:37
and looks at the endpoints of the walls,
01:39
and if those endpoints are connected
01:41
to the endpoint of another wall, it'll
01:43
continue highlighting them in a chain.
01:46
So we call this chain selection.
01:48
Before you click, I want you to move your mouse
01:51
slightly just a little bit.
01:53
And notice that the chain in this case
01:55
can actually do an inner chain or an outer chain.
01:59
Now, either way, we're getting the tall walls
02:01
in the middle of the building.
02:02
But notice that we either get the two short walls
02:06
on the interior or, if we move slightly,
02:09
we get the four exterior walls that
02:12
are short in the upper portion of the building.
02:15
So what we want to do is make sure we're highlighting
02:18
the perimeter walls, what we see on my screen
02:20
now, not those two interior ones.
02:23
And that's when you want to click to make that selection.
02:26
Now, over here on the Properties palette,
02:28
it'll say, walls eight.
02:30
So if it doesn't say eight walls,
02:32
then click anywhere in white space and try again.
02:35
So now that we have the perimeter selected,
02:36
let's make a simple modification.
02:38
Open up the type selector.
02:40
Scroll through the list of available wall types.
02:43
And notice that up here toward the top
02:45
there are several exterior brick walls.
02:47
Let's choose Brick on Metal Stud.
02:50
Now, after you choose that, click an empty white space
02:53
to deselect the walls, and it will
02:55
appear like the exterior surface of the walls is shaded in gray.
02:59
While in reality, if you zoom in using the wheel on your mouse,
03:03
what you'll actually see is that gray shading is really
03:06
a hatch pattern that's applied to the surface of those walls.
03:10
So we're now seeing the bricklayer
03:12
that's on the exterior outermost face of the wall.
03:16
Now, you can see that in floor plan as well.
03:19
So if you come back over here and click the Level 1 floor
03:22
plan view--
03:23
and let's roll the wheel to zoom in on one of the exterior
03:27
locations of the building.
03:29
At the moment, you're not seeing any brick.
03:32
But that's simply because each view in Revit
03:35
has its own settings.
03:37
And one of the settings that's available
03:39
is the level of detail setting.
03:42
And there are three possibilities-- coarse, medium,
03:44
and fine.
03:45
When you're set to coarse, as we are here,
03:47
it only shows the outer thickness and none
03:50
of the interior layers.
03:52
So we can change the level of detail
03:55
using the small little pop-up here on the View control
03:58
bar at the base of the screen.
03:60
So we're currently set to coarse.
04:02
If you choose either medium or fine,
04:05
the brick will display, as will all
04:07
of the other internal layers, within the thickness
04:10
of the wall.
04:12
Now, just what exactly are those other internal layers?
04:15
Well, let's take a look.
04:16
So let's go ahead and select any one of those exterior walls.
04:20
And then go to the Properties palette
04:22
and click the Edit Type button.
04:24
Now, we were just here a moment ago looking
04:26
at the generic wall.
04:28
Now, if we click Edit Structure, notice the difference.
04:31
Now, here, it's a little difficult
04:32
to read because it's so compressed.
04:35
So you can actually stretch this window
04:38
and make it a little bit larger so that the scroll bars go away
04:42
and you can read all of the entries.
04:44
And notice what we have here is that previously we only had
04:47
that one layer inside the core.
04:49
Well, now, we actually have several layers
04:52
on the exterior side of the wall and several layers
04:56
on the interior side of the wall.
04:58
Each layer has its own thickness.
05:00
Each layer has its own material.
05:03
So that accounts for the extra line work and detail
05:07
that you're seeing within the thickness of the wall
05:09
here in the floor plan, and it also
05:11
accounts for why we're seeing the brick hatch
05:13
pattern in the 3D view.
05:15
So that's coming from this finished layer
05:18
here and the brick common material that's
05:20
applied to that layer.
05:22
Now, let's say that we wanted the thickness of this wall
05:26
to not change when we made it into a brick wall.
05:29
So notice here that the total thickness is currently 1 foot
05:35
It actually grew in thickness by nearly 2 inches
05:38
when we switched from the generic wall
05:40
to the non-generic wall.
05:42
Now, what I don't want you to do is start making changes
05:44
right away, because if you do, those changes will actually
05:47
immediately apply everywhere throughout the building.
05:50
So what we're going to do instead is cancel one time.
05:53
That takes us back to the Type Properties window.
05:56
And it's usually considered a best practice
05:58
to duplicate the type first before you make changes.
06:02
So right here, we can click Duplicate.
06:04
I'll remove the number two that it suggests in the name
06:08
and then click my mouse right in front of the word "Metal,"
06:11
and I'll type in 4 inch metal stud instead.
06:16
So now I've created this new type called Exterior Brick
06:19
on 4 inch Metal Stud.
06:21
Now, if you go back to the Edit Structure button,
06:25
widen the window again so you can read everything,
06:27
notice that that does not actually
06:29
change the thickness of the metal stud layer.
06:33
You still have to do that.
06:35
But now we can put in 4 inches here.
06:39
Now, make sure you're doing inches and not feet.
06:41
So either put 0 space 4 or 4 in the inch symbol.
06:44
And notice that the total thickness now
06:47
has adjusted to 11 and 7/8 of an inch.
06:49
Now, again, my goal was to get to 12.
06:52
So that means I now need to add an 1/8 of an inch
06:54
back in somewhere.
06:55
Let's consider the finished layer here.
06:58
It's currently set Gypsum Wall Board,
07:00
but it's only a 1/2 inch thick.
07:02
Now, it would be unusual to use 1/2 inch
07:05
drywall in a commercial building,
07:07
so I think we can easily add that extra 1/8 of an inch here,
07:11
and that will take care of what we need to accomplish.
07:14
So what I'm going to do is select the 1/2,
07:18
change that to
07:20
I click outside of that field, the math will be recalculated.
07:24
Notice that my total thickness is now 1.
07:27
So if I click OK and then OK again,
07:30
watch the thickness of this wall that we have selected
07:33
change when we click OK.
07:35
So you see how it got slightly thinner
07:37
and it went back to being flushed up
07:39
against this existing interior wall.
07:42
The rest of these walls are still using the original type.
07:46
So I'm going to select one of the other walls,
07:49
any other wall, not the one that I
07:51
had selected when I duplicated.
07:53
Right click and choose Select All Instances,
07:57
Visible in the View.
07:59
Now, you might need to zoom out in order to see what that does.
08:03
But notice that that selects every exterior wall
08:06
except the one that we were just working on because that one
08:10
is a different type.
08:11
So when you say Select All Instances,
08:13
it selects all of the walls of the same type.
08:17
So now that those are selected, I can come over here
08:20
to the type selector.
08:21
And instead of Brick on Metal Stud,
08:23
I'll change them 4 inch Brick on Metal Stud.
08:27
Now, if we click back to our 3D view,
08:29
we're not really going to see much difference here,
08:32
but what I wanted to point out to you here in the 3D view
08:35
is there's still one more thing that I'd like
08:37
to do with this new wall type.
08:39
Notice here that this wall stops right here and this one
08:42
stops right there and we have this large gap
08:45
open on the second floor.
08:47
So let's double click the Level 2 floor plan
08:50
to open up the second floor.
08:52
Let me put my mouse right about here and kind of
08:54
roll in so that I can see the end of this wall
08:57
and the end of that wall.
08:59
And what I want to do is close in that corner there
09:02
using this new wall type that we just created.
09:06
So to do that, I'll go to the Wall command or type WA.
09:10
I'll go to the type selector, scroll to the top of the list,
09:14
and there's my Brick on 4 inch Metal Stud.
09:17
So I'll choose that.
09:18
Before you go and start clicking points on screen,
09:22
pay attention to the rest of the properties on the Properties
09:25
palette because it remembers the settings you used previously.
09:28
And when I created the ribbon curtain wall down
09:32
at the bottom, I changed some of these other settings,
09:35
and it remembers that now.
09:36
So the base constraint is defaulting to level 2.
09:39
I'm going to accept that.
09:41
But the base offset I want to be 0.
09:44
And then for the top constraint, it defaults to unconnected.
09:47
Well, I want to change that to roof instead.
09:50
And then, finally, I want to add a 3 foot top offset
09:54
for the parapet height so that these walls that I'm
09:57
about to draw will match the heights of the ones that
09:60
are already there.
10:01
So now that I've got those settings in place,
10:04
I can start drawing this new wall at the end of the existing
10:08
one, pull it straight up until it finds the end
10:13
point near the other wall.
10:15
And you might need to zoom sometimes.
10:17
There it is right there.
10:18
Sometimes if you zoom the wheel, it'll
10:20
force it to sense where that other wall is.
10:23
So you can see that dashed line shows up.
10:25
I'm going to click.
10:26
And then I'll turn the corner and click again right here.
10:31
Let's click the Modify tool to cancel.
10:33
Let's go back to the 3D view tab.
10:35
We just added this wall and this wall.
10:38
Let's hold the Shift key down, rotate the view
10:42
around by dragging the wheel, and zoom in just a touch.
10:46
You can see that we now have those two new brick walls here
10:48
and here, and they match the heights of the existing
10:51
ones that were already there.
10:53
Now, the final thing you might want to do
10:55
is locate one of the interior walls.
10:57
And notice, they're still set to generic walls.
10:60
So I can use that same right-click method that we did
11:03
before, select all instances visible in the view--
11:06
I can do this right here in 3D--
11:09
and then open up my type selector
11:11
and choose a more appropriate type.
11:14
So just like we have several exterior walls,
11:16
we also have several interior walls here.
11:19
So I'm going to choose the 4 and 7/8 inch one.
11:22
And as you can see, by assigning different wall types,
11:25
you can begin to articulate what the actual material
11:28
construction of the wall assemblies are.

INSTRUCTOR: Customizing wall geometry
00:09
is as simple as applying or defining a new wall type.
00:14
The Type Properties dialog contains many settings
00:16
that can be customized to create nearly any imaginable wall
00:19
design.
00:21
Now, currently our model uses only generic walls.
00:24
Now, generic walls just have a single component
00:27
of a designated thickness.
00:29
But by choosing alternate types, we
00:31
can express the construction of the walls
00:34
and their internal materials a little bit more accurately.
00:37
Now, I'm going to do this work in a 3D view.
00:40
So I'm going to go to the Default 3D View icon here.
00:43
I'll roll my wheel a couple clicks just to zoom in a touch,
00:46
and I will highlight this exterior wall here.
00:49
And notice that it's a basic wall, generic 12-inch wall.
00:53
I'm going to select that wall, go to Edit Type,
00:56
and then here in the Type Properties dialog,
00:58
there's an Edit Structure button at the top,
01:01
and I'll edit one more time.
01:02
Notice that there's just the single layer here, layer number
01:05
two, that's set to By Category, which essentially means that it
01:08
doesn't have its own material.
01:10
And its total thickness is 1 foot.
01:14
So that's what we mean by a generic wall.
01:17
So now what we're going to do is we're
01:18
going to select the exterior perimeter of the walls
01:21
and change them to a different wall assembly instead.
01:24
So let's highlight that same exterior wall.
01:27
But this time, before you click, I
01:29
want you to press the Tab key.
01:31
Now, notice that when you press Tab,
01:34
it goes down the lengths of the walls
01:37
and looks at the endpoints of the walls,
01:39
and if those endpoints are connected
01:41
to the endpoint of another wall, it'll
01:43
continue highlighting them in a chain.
01:46
So we call this chain selection.
01:48
Before you click, I want you to move your mouse
01:51
slightly just a little bit.
01:53
And notice that the chain in this case
01:55
can actually do an inner chain or an outer chain.
01:59
Now, either way, we're getting the tall walls
02:01
in the middle of the building.
02:02
But notice that we either get the two short walls
02:06
on the interior or, if we move slightly,
02:09
we get the four exterior walls that
02:12
are short in the upper portion of the building.
02:15
So what we want to do is make sure we're highlighting
02:18
the perimeter walls, what we see on my screen
02:20
now, not those two interior ones.
02:23
And that's when you want to click to make that selection.
02:26
Now, over here on the Properties palette,
02:28
it'll say, walls eight.
02:30
So if it doesn't say eight walls,
02:32
then click anywhere in white space and try again.
02:35
So now that we have the perimeter selected,
02:36
let's make a simple modification.
02:38
Open up the type selector.
02:40
Scroll through the list of available wall types.
02:43
And notice that up here toward the top
02:45
there are several exterior brick walls.
02:47
Let's choose Brick on Metal Stud.
02:50
Now, after you choose that, click an empty white space
02:53
to deselect the walls, and it will
02:55
appear like the exterior surface of the walls is shaded in gray.
02:59
While in reality, if you zoom in using the wheel on your mouse,
03:03
what you'll actually see is that gray shading is really
03:06
a hatch pattern that's applied to the surface of those walls.
03:10
So we're now seeing the bricklayer
03:12
that's on the exterior outermost face of the wall.
03:16
Now, you can see that in floor plan as well.
03:19
So if you come back over here and click the Level 1 floor
03:22
plan view--
03:23
and let's roll the wheel to zoom in on one of the exterior
03:27
locations of the building.
03:29
At the moment, you're not seeing any brick.
03:32
But that's simply because each view in Revit
03:35
has its own settings.
03:37
And one of the settings that's available
03:39
is the level of detail setting.
03:42
And there are three possibilities-- coarse, medium,
03:44
and fine.
03:45
When you're set to coarse, as we are here,
03:47
it only shows the outer thickness and none
03:50
of the interior layers.
03:52
So we can change the level of detail
03:55
using the small little pop-up here on the View control
03:58
bar at the base of the screen.
03:60
So we're currently set to coarse.
04:02
If you choose either medium or fine,
04:05
the brick will display, as will all
04:07
of the other internal layers, within the thickness
04:10
of the wall.
04:12
Now, just what exactly are those other internal layers?
04:15
Well, let's take a look.
04:16
So let's go ahead and select any one of those exterior walls.
04:20
And then go to the Properties palette
04:22
and click the Edit Type button.
04:24
Now, we were just here a moment ago looking
04:26
at the generic wall.
04:28
Now, if we click Edit Structure, notice the difference.
04:31
Now, here, it's a little difficult
04:32
to read because it's so compressed.
04:35
So you can actually stretch this window
04:38
and make it a little bit larger so that the scroll bars go away
04:42
and you can read all of the entries.
04:44
And notice what we have here is that previously we only had
04:47
that one layer inside the core.
04:49
Well, now, we actually have several layers
04:52
on the exterior side of the wall and several layers
04:56
on the interior side of the wall.
04:58
Each layer has its own thickness.
05:00
Each layer has its own material.
05:03
So that accounts for the extra line work and detail
05:07
that you're seeing within the thickness of the wall
05:09
here in the floor plan, and it also
05:11
accounts for why we're seeing the brick hatch
05:13
pattern in the 3D view.
05:15
So that's coming from this finished layer
05:18
here and the brick common material that's
05:20
applied to that layer.
05:22
Now, let's say that we wanted the thickness of this wall
05:26
to not change when we made it into a brick wall.
05:29
So notice here that the total thickness is currently 1 foot
05:35
It actually grew in thickness by nearly 2 inches
05:38
when we switched from the generic wall
05:40
to the non-generic wall.
05:42
Now, what I don't want you to do is start making changes
05:44
right away, because if you do, those changes will actually
05:47
immediately apply everywhere throughout the building.
05:50
So what we're going to do instead is cancel one time.
05:53
That takes us back to the Type Properties window.
05:56
And it's usually considered a best practice
05:58
to duplicate the type first before you make changes.
06:02
So right here, we can click Duplicate.
06:04
I'll remove the number two that it suggests in the name
06:08
and then click my mouse right in front of the word "Metal,"
06:11
and I'll type in 4 inch metal stud instead.
06:16
So now I've created this new type called Exterior Brick
06:19
on 4 inch Metal Stud.
06:21
Now, if you go back to the Edit Structure button,
06:25
widen the window again so you can read everything,
06:27
notice that that does not actually
06:29
change the thickness of the metal stud layer.
06:33
You still have to do that.
06:35
But now we can put in 4 inches here.
06:39
Now, make sure you're doing inches and not feet.
06:41
So either put 0 space 4 or 4 in the inch symbol.
06:44
And notice that the total thickness now
06:47
has adjusted to 11 and 7/8 of an inch.
06:49
Now, again, my goal was to get to 12.
06:52
So that means I now need to add an 1/8 of an inch
06:54
back in somewhere.
06:55
Let's consider the finished layer here.
06:58
It's currently set Gypsum Wall Board,
07:00
but it's only a 1/2 inch thick.
07:02
Now, it would be unusual to use 1/2 inch
07:05
drywall in a commercial building,
07:07
so I think we can easily add that extra 1/8 of an inch here,
07:11
and that will take care of what we need to accomplish.
07:14
So what I'm going to do is select the 1/2,
07:18
change that to
07:20
I click outside of that field, the math will be recalculated.
07:24
Notice that my total thickness is now 1.
07:27
So if I click OK and then OK again,
07:30
watch the thickness of this wall that we have selected
07:33
change when we click OK.
07:35
So you see how it got slightly thinner
07:37
and it went back to being flushed up
07:39
against this existing interior wall.
07:42
The rest of these walls are still using the original type.
07:46
So I'm going to select one of the other walls,
07:49
any other wall, not the one that I
07:51
had selected when I duplicated.
07:53
Right click and choose Select All Instances,
07:57
Visible in the View.
07:59
Now, you might need to zoom out in order to see what that does.
08:03
But notice that that selects every exterior wall
08:06
except the one that we were just working on because that one
08:10
is a different type.
08:11
So when you say Select All Instances,
08:13
it selects all of the walls of the same type.
08:17
So now that those are selected, I can come over here
08:20
to the type selector.
08:21
And instead of Brick on Metal Stud,
08:23
I'll change them 4 inch Brick on Metal Stud.
08:27
Now, if we click back to our 3D view,
08:29
we're not really going to see much difference here,
08:32
but what I wanted to point out to you here in the 3D view
08:35
is there's still one more thing that I'd like
08:37
to do with this new wall type.
08:39
Notice here that this wall stops right here and this one
08:42
stops right there and we have this large gap
08:45
open on the second floor.
08:47
So let's double click the Level 2 floor plan
08:50
to open up the second floor.
08:52
Let me put my mouse right about here and kind of
08:54
roll in so that I can see the end of this wall
08:57
and the end of that wall.
08:59
And what I want to do is close in that corner there
09:02
using this new wall type that we just created.
09:06
So to do that, I'll go to the Wall command or type WA.
09:10
I'll go to the type selector, scroll to the top of the list,
09:14
and there's my Brick on 4 inch Metal Stud.
09:17
So I'll choose that.
09:18
Before you go and start clicking points on screen,
09:22
pay attention to the rest of the properties on the Properties
09:25
palette because it remembers the settings you used previously.
09:28
And when I created the ribbon curtain wall down
09:32
at the bottom, I changed some of these other settings,
09:35
and it remembers that now.
09:36
So the base constraint is defaulting to level 2.
09:39
I'm going to accept that.
09:41
But the base offset I want to be 0.
09:44
And then for the top constraint, it defaults to unconnected.
09:47
Well, I want to change that to roof instead.
09:50
And then, finally, I want to add a 3 foot top offset
09:54
for the parapet height so that these walls that I'm
09:57
about to draw will match the heights of the ones that
09:60
are already there.
10:01
So now that I've got those settings in place,
10:04
I can start drawing this new wall at the end of the existing
10:08
one, pull it straight up until it finds the end
10:13
point near the other wall.
10:15
And you might need to zoom sometimes.
10:17
There it is right there.
10:18
Sometimes if you zoom the wheel, it'll
10:20
force it to sense where that other wall is.
10:23
So you can see that dashed line shows up.
10:25
I'm going to click.
10:26
And then I'll turn the corner and click again right here.
10:31
Let's click the Modify tool to cancel.
10:33
Let's go back to the 3D view tab.
10:35
We just added this wall and this wall.
10:38
Let's hold the Shift key down, rotate the view
10:42
around by dragging the wheel, and zoom in just a touch.
10:46
You can see that we now have those two new brick walls here
10:48
and here, and they match the heights of the existing
10:51
ones that were already there.
10:53
Now, the final thing you might want to do
10:55
is locate one of the interior walls.
10:57
And notice, they're still set to generic walls.
10:60
So I can use that same right-click method that we did
11:03
before, select all instances visible in the view--
11:06
I can do this right here in 3D--
11:09
and then open up my type selector
11:11
and choose a more appropriate type.
11:14
So just like we have several exterior walls,
11:16
we also have several interior walls here.
11:19
So I'm going to choose the 4 and 7/8 inch one.
11:22
And as you can see, by assigning different wall types,
11:25
you can begin to articulate what the actual material
11:28
construction of the wall assemblies are.
Currently our model uses only Generic walls. But by choosing alternate types, we can express the construction of the wall and its materials.

Figure 10–1 Pre-highlight one of the exterior walls
Figure 10–2 Use the tab key to chain select the exterior walls
Figure 10–3 Zooming in closer reveals a brick pattern on the surface of the walls
Notice that as you zoom in closer, a brick pattern appears on the walls. If your brick appears on the inside of the building instead, chain select the walls again and then tap the spacebar to flip them.
In plan view, the change to the exterior walls will not be obvious. This is because the plan view is set to display “Course” level of detail. In course level, only the outlines of the walls display.
Figure 10–4 Change to Medium level of detail to see the wall's layered assembly in plan
If you look carefully at the dimensions in the plan, you will notice that some have changed. This is because in addition to now displaying internal components, changing from Generic to Brick on Metal Stud has also changed the thickness of the exterior walls, thus impacting the value of some dimensions (see Figure 10–5).
Figure 10–5 Some dimensions are affected by the change in wall type
Let’s assume that the design called for keeping the thickness of the wall unchanged when changing types. In other words, let’s say we needed the wall to remain 1'-0" thick. Create a new type and modify it to accomplish this.
If you want to change all existing walls of this type throughout the entire project, simply make your edits and then click OK. If instead you would prefer to preserve the original, use the Duplicate button to make a copy and assign it instead. Best practice is to duplicate.
Figure 10–6 Select any exterior wall, duplicate its type and then edit the structure
Figure 10–7 Adjust the thickness of layers and note the effect on the total
If you get an error regarding your curtain wall, click the Delete Elements button to resolve it. The curtain wall will recreate any deleted elements it requires.
All dimensions should return to their previous values. You will not always be able to adjust the wall thickness like this in every project. In cases where the walls must change thickness, you may need to adjust some of their locations after the change. You can also explore Location Line, (see the next topic).
Once you have created a new wall type, it can be used like any other.
Pay close attention to the settings on the Properties palette as Revit is remembering the curtain wall we drew previously and defaulting to those values.
