After completing this lesson, you'll be able to understand stairs, use stair components, create multi-story stairs, and use shaft openings.
00:15
The objective domains covered are, 1.1f, work with stairs.
00:20
To create most staircases, you can use common components to build a stair assembly such as runs, build a new shape binders, and landings.
00:29
For more complex stairs, you can sketch the boundary, define custom trades, and also landing profiles.
00:36
Steel and timber stairs can be created by using steel string of profiles and custom trade profiles.
00:43
Also note that stairs can host reinforcement bar, but cannot be joined to other structured elements such as floors.
00:50
A shaft opening is very useful when there is a requirement to maintain vertical openings that cut through multiple floors.
00:58
Symbolic lines can be drawn, which are then displayed on each floor that the shaft cuts.
01:03
In the example shown, the shaft opening is used for lift shafts and also for drainage pipe openings.
01:11
Go ahead and open up the model 011-Work with stairs.
01:16
You'll notice that the model opens up in the 3D view.
01:20
Our first task is to create a multi-story staircase in this section of the structure.
01:26
To begin, we define a staircase in a plane view.
01:30
Let's begin by opening up the 00-Ground Floor plane.
01:37
We'll then zoom in to the area where we want to create our stair.
01:41
You'll note here that we have a reference plane, which is indicating the starting position of our staircase.
01:48
To create a stair, on the Architecture ribbon, select "Stair".
01:54
Here you'll note that we're using components, and in this case, we're going to use the Straight component here.
02:01
Our intention is to create a u-shape staircase with a half landing.
02:06
On the options bar, you'll notice here that the location line is set to the right hand side of the stair.
02:12
We're not having any offset from selective positions.
02:16
My run width is 3 foot and 6 inches.
02:19
And I'm going to create an automatic landing as I model the staircase.
02:25
In the Properties palette, you'll note here that we're using an In Situ Concrete Stair for Core 1.
02:31
The base level is set to 00-Ground Floor, but we want to adjust the top level to be 01-First Floor.
02:40
Now when I do this, you'll notice now that the actual rise height is calculated,
02:44
and also that the desired number of stairs is currently calculated at 17.
02:49
The actual number of risers that are created is reported here in the Properties is a read-only value.
02:56
Before I go ahead and create a stair, I just want to check the Railing settings.
03:00
So on the context ribbon, you'll note that we have the Railing tool, let's select this.
03:05
We just want to ensure that the railings are set to none, as this is going to be a structural staircase.
03:11
Let's go ahead and select "OK".
03:15
We're now ready to model our components.
03:18
To begin, I'll snap to the end point of our reference plane.
03:22
I'm now going to define my first run.
03:26
You'll note that on-screen is displayed the number of risers created and the number of remaining.
03:31
So in this example here, I'm going to create nine risers on my first run, and then eight risers on my second run.
03:43
In the Properties palette, you'll now note that the actual number of risers matches the desired number of risers.
03:49
Also, our desired stair height is calculated out at 11 feet.
03:56
On the context ribbon, let's select Finish Edit Mode, and our staircase has been modeled.
04:02
To help us understand this a bit further,
04:04
we're going to create a section that's going to cut through the first run of stairs and edify to the second run of stairs.
04:11
On the quick access toolbar, select "Section", create a section that initially runs down this grid here,
04:20
and we'll then move this or reposition this over the first run of the stairs.
04:25
I'll change the section depth here just to edit right to the stair itself.
04:31
We can then go ahead and open up that section.
04:37
You'll note here that the stair isn't quite high enough to reach the top of slab.
04:42
The reason for this is that the run settings have start and end with rise.
04:47
To edit this, I'm going to select the Tab key just to select this run here.
04:53
Once I have this run selected, you'll note in the Properties palette, we have the option of begin with riser and end with riser.
05:00
So I want to begin with a riser, but I don't want to end with a riser.
05:04
So I'm going to remove that.
05:07
Now this little warning here is now saying that my staircase cannot reach the top of the slab,
05:12
because obviously here, I've told it not to end with the rise.
05:15
The solution here is to extend the lengths of the run which will add another step.
05:20
Click "OK" to the warning.
05:23
And here we'll go back to our Ground Floor plane.
05:27
We'll select our staircase, click Edit Stair.
05:33
I can then select this run upstairs, and I can use the grip here to drag the run end and to incorporate another step.
05:43
If I now select the Finish Edit Mode tool, and once again go back into the section, you'll now note that my stair reaches the slab.
05:55
Next we'll create a multi-story stair.
05:58
Switch into your 3D view and you can now see that we have our staircase that we've just created in three dimensions.
06:05
Also note here that my levels are displayed in 3D.
06:10
To create a multi-story stair, select the Stair, and note on the context ribbon, we have the option of selecting levels.
06:20
Now here I can use a crossing window to select the levels that I want the multi-story stair to span between.
06:27
If I then go ahead and select "Finish", you'll note that the multi-story stair is created.
06:36
Something to note that if I select the multi-story stair,
06:39
I can then connect or disconnect levels if I later on add or remove levels from my building structure.
06:48
Finally, we create a shaft opening to complete our stairs.
06:53
Let's switch back to the Ground Floor plane and we'll note here that we have our staircase now created.
07:00
On the Architecture ribbon, you'll notice we have the Shaft command. Let's go ahead and select that.
07:06
And now on the context ribbon, you'll note that we have two modes.
07:10
We have the Boundary Line mode, which is where we draw the plane shape of our vertical shaft.
07:15
And then we have a Symbolic Line mode where we can draw symbology to represent an opening.
07:22
Let's begin by creating our boundary lines.
07:27
So the shape that I want to open is going to be across here, and it's just going to incorporate the staircase itself.
07:40
In this example, we're not required to create symbolic lines.
07:44
In the Properties palette, you'll note that we can set our base constraint for the shaft opening.
07:49
Notice it's automatically going down negative 1 foot.
07:53
The reason for this is the story actually penetrates through the ground floor slab if that was a requirement,
07:58
and it's going to also go up to the top constraint.
08:01
Now currently it's only going up to the first floor.
08:03
We're going to change this and go all the way up to the fifth floor.
08:09
Let's then go ahead and select Finish Edit mode.
08:15
Once again to help us understand this, we can switch back to our 3D view.
08:20
And we can now see we have a shaft opening incorporated into our slab.
08:28
If we now switch back to our ground floor plane, and we zoom into the core area,
08:34
you'd also notice here that we have some additional shaft openings that have been created, and these are incorporating symbolic lines.
08:41
So for example here, if we select the shaft opening and we select Edit Sketch on the context ribbon,
08:48
you'll note here that these items have been created with symbolic lines.
08:53
Each of those openings will then appear on subsequent floor planes.
08:57
So if I open up the second floor plane and we also zoom into the shaft openings here, you can see that they're still displayed.
00:04
After completing this lesson, you'll be able to understand stairs, use stair components, create multi-story stairs, and use shaft openings.
