The U shape stair is a stair that returns through 100 and 80 degrees.
00:07
Usually with a landing to facilitate the turn,
00:11
they're commonly found in multi story buildings
00:13
as their form is an efficient use of space
00:16
with the top of one stair finishing adjacent to the start of the next stair.
00:20
And looking at the rear stairs, 3d view,
00:23
we can see the area where we will create the stairs.
00:28
We'll start by creating a U shape stair between levels one and two.
00:32
And then we'll create a new stair type to suit this location within the building
00:39
to create the stairs.
00:40
We'll first open the level one rear stairs,
00:43
floor plan view from the project browser.
00:46
And before we actually create the stairs, we'll play some reference planes in
00:50
to act as a guide to accurately position the stairs.
00:53
So first from the architecture ribbon tab on the work playing panel,
00:58
we'll click on the reference plane tool,
01:00
then we can just sketch across horizontally just above
01:03
the doors here to create the first work plan.
01:07
And then we'll create two more vertical work planes in the center of the stairwell.
01:12
So
01:12
we'll place the first one down here
01:16
and then edit the temporary dimension here to be 4 ft.
01:21
And now we'll sketch the second one to the left of this one.
01:26
Um We'll edit this temporary dimension here,
01:28
but we need this to be from the work plan that we've just created.
01:32
So
01:33
using the end control here,
01:35
we'll drag this across so it snaps to the reference plane here.
01:39
And now we can edit this temporary dimension to be 2 ft.
01:43
So now we've got those placed. I'll click modify to finish placing reference blas
01:48
and to locate the horizontal reference plane in the correct location,
01:52
we'll use the aligned dimension tool.
01:54
So
01:55
from the annotation ribbon tab on the dimensions panel here,
01:58
we'll choose the aligned dimension button
02:03
looking at the options bar. Here we have all faces set as the preference.
02:07
So we can first click on the internal face of the back wall
02:10
here and then the reference plane for the second witness line here.
02:14
Now we just click to the left side to place this dimension.
02:18
I'll choose,
02:18
modify to finish placing dimensions and then select the reference plan.
02:24
And now we can see that the dimension is editable here.
02:26
So we'll click on the dimension value and we'll change this to be 13 ft six
02:31
and this will locate the lower reference plane in the correct location.
02:38
So now to create the stairs, we'll go to the architecture ribbon tab
02:42
and from the circulation panel, we'll click on the stair tool.
02:48
Now looking at the properties palette here,
02:50
you can see we have the cast in place a monolithic stair
02:53
and looking at constraints, we have level one as the base level.
02:56
Level two is the top level and that gives us a desired stair height of 10 ft.
03:02
The desired number of rises is 18
03:04
and this is calculated by the type properties. So we'll click edit type
03:09
and we can see here the maximum riser height is set to seven inches
03:13
and this is used along with the desired stare height of 10 ft
03:16
to calculate the 18 writers
03:19
will not make any changes to a click, cancel to close this box.
03:24
And now looking at the options bar,
03:26
we can see we have the automatic landing option enabled.
03:29
The actual run width is 3 ft. So let's change this to 4 ft.
03:35
Now,
03:35
the location line is currently run center and we need to change this to be run right.
03:41
Looking at the great stair ribbon,
03:43
we can see we have the run tool set and it's set to be a straight run.
03:46
So
03:47
let's go into the view here and
03:49
we'll start sketching at the bottom of the stairs.
03:52
So we'll click on the intersection of the lower reference
03:54
plane and the the left hand vertical one here.
03:57
And now as we move our mouse vertically up the screen,
03:60
we can see we have the text at the bottom here telling us how many rises,
04:03
we've created and
04:05
how many remain.
04:07
And once it says we have nine created and nine remaining, we'll click to set that run
04:13
now to create the U shape that we'll go across and, and turn back on ourselves. So
04:18
aligning with the right reference plane in the top of the previous run,
04:22
we'll click on this intersection
04:25
and then we'll work our way down
04:27
until we have all waiting visor created and click to set that.
04:32
So we can see the landing that's been created with the automatic landing option.
04:36
We need to extend this back to the rear wall. So
04:40
using the shape handle here, we'll drag this back so it snaps to the rear wall
04:46
and now using the middle shape handle here on the opposite side,
04:49
we'll drag this back until we have a 4 ft width
04:53
and that will give us room to transition from the runs to the landing.
04:58
So now that the stairs are complete, we'll click,
05:00
finish edit mode to create those stairs
05:03
and we'll swap back to the rear stairs, 3d view.
05:07
And we can see now that we've got those stairs created
05:09
and they're spanning between level one and level two.
