00:03
An elevator pit is positioned below the first floor and
00:06
provides a recess for the elevator and associated machinery.
00:10
The elevator pit is constructed from structural foundation slabs and walls.
00:16
In this video,
00:17
we're going to create a model for an elevator pit and create the required details.
00:22
We'll begin by creating our level one foundation slab
00:26
to do this. Go ahead and select the structure ribbon
00:29
and on the structure ribbon, select structural foundation slab
00:34
in the properties paddock in a type selector.
00:37
Let's ensure that we're using our six inch concrete slab.
00:41
You'll notice in the level one plan that we
00:43
have a number of reference planes already configured.
00:46
The outside reference planes designate the boundary of our foundation slab.
00:50
The internal reference planes are marking the
00:53
structural opening for our elevator pit.
00:55
So we'll begin by selecting the rectangle tool on the draw panel
01:01
here. We can simply trace the reference points
01:05
and I do the same thing for our structural opening
01:09
to finalize the structural foundation slab.
01:12
We'll select finish, edit mode on the context ribbon
01:16
to deselect the slab. We select modifier.
01:19
You will also notice that we have a spam direction symbol.
01:22
We'll select the span direction symbol. And in this example, we'll press delete,
01:27
we're now ready to create the vertical walls for our elevator shaft
01:30
to do this. Let's go ahead and zoom in to the internal opening
01:34
and the elevator pit walls are going to be created with the wall command
01:39
on the structure ribbon. Let's go ahead and select all
01:43
in the properties pad in the type selector.
01:45
Let's just ensure that we're currently using concrete wall 12 inch
01:50
on the options bar.
01:51
We'll ensure that the wall is going to be modeled down to a depth of the elevator pit
01:56
and the location line will be finish face interior
02:00
on the draw panel. Let's select rectangle
02:03
and we'll construct our walls.
02:05
Notice here that I'm constructing the walls
02:07
right away from the structural opening.
02:09
The reason for this is we'll use the align command
02:12
to constrain each of the walls to the structural opening
02:16
to do this on the context ribbon, we can select the align command.
02:20
We'll begin by selecting our edge on our foundation slab
02:24
and then the internal face of our wall.
02:26
Here,
02:27
it's very important to lock and constrain that
02:29
wall to the edge of the foundation slab.
02:32
We'll do the same here
02:35
and again, lock that.
02:37
Yeah
02:39
and again here
02:43
to release the align command on the context ribbon select, modify,
02:47
we can now create the structural foundation slab at the base of our elevator pit
02:52
to do this in the project browser under structural plans.
02:56
Let's open up the elevator pit plan
02:59
to create another structural foundation slab.
03:01
We right mouse click,
03:03
we go to recent commands and here we'll use structural foundation slab
03:08
in the properties pallet in a type selector.
03:10
Let's now ensure that we're using a 12 inch foundation slab
03:15
on the context ribbon in the drawer panel.
03:17
You'll note here that we have pick walls selected by default
03:22
on the options bar.
03:23
We're just going to ensure that the offset is set to 12 inches or 1 ft.
03:27
We can now go ahead and create the boundary line for our foundation slab.
03:31
Notice as I move over the wall rait
03:33
shows a preview designating the side of the offset.
03:36
I want to ensure that the offset goes to the outside of our walls.
03:40
We can then go around and pick each wall in turn
03:43
and now we can finalize our structural
03:45
foundation slab by selecting finish edit mode.
03:49
Once again, I'll deselect the foundation slab by selecting modifier.
03:53
I'll select the span direction symbol and press delete.
03:56
Let's now review our model in 3D
03:59
in the project browser on the 3D views folder, double click on 3D working view.
04:05
We can now see our model.
04:08
What's very important now is to attach the walls to both foundation slabs
04:14
to do this. We'll move over one of the walls so it's preselected
04:17
and then we can press the tab key to find the chain of walls.
04:21
We'll then select those walls
04:23
and notice on the context ribbon, we have attach top base.
04:28
Let's go ahead and select, attach top base
04:32
on the options bar. You'll note that the first option is top.
04:36
So here I'm going to select this structural foundation slab.
04:41
The walls have now attached to the socket of that slab
04:44
will do a very similar thing for the structural
04:46
foundation slab at the base of the elevator pit.
04:50
So again, on the context ribbon, we'll select attach top base.
04:54
But this time on the options bar ensure that we've selected base.
04:60
We can then rotate the model round
05:02
and select the foundation slab at the base of the elevator pit.
05:06
So now we have a fully parametric model
05:09
to test this. You can see here that we have our levels.
05:12
If I select the elevator pit level here, I'm going to tie up in negative 6 ft
05:17
and we can now see the levels dropped.
05:19
But the key thing here is you'll notice the
05:21
walls have remained connected to the two slabs.
05:27
OK. Let's review our model in section
05:30
to do this. We'll switch to our level one plan
05:33
to create the section. We'll go to the view ribbon
05:37
and we'll select section
05:39
to construct the section. We'll select a position approximately here.
05:43
If you hold down the shift key,
05:45
the section line will be constrained to draw orthogonal
05:48
and we'll place this section approximately here
05:52
in the property's pallet.
05:53
What I'd like to do here is change the far clip off set to six inches.
05:58
We can then go ahead and open up the section
06:00
to do this. We can double click on the section head and here's our section.
06:04
If we zoom into the section,
06:06
you'll notice that the blinding is already
06:08
added into our structural foundation slabs.
06:11
We're now going to use a detail line to show some damp proof membrane
06:15
to do this. We'll select the annotate ribbon
06:18
and on the detail panel, we'll select detail line
06:22
on the context ribbon. We'll ensure here that we're using in the line style membrane
06:27
and on the draw panel, you'll note here that line is already selected
06:31
in the options bar. We just need to ensure that chain is switched on.
06:35
And here for the offset, we'll choose two inches.
06:39
We can now start on the right hand side and I'm going to snap here
06:42
and now I can trace off the outside boundary of my elevator pit.
06:52
As I do this, you can see the detail lines are created with that two inch offset
06:58
to complete the command. We can go ahead and select modifier on the context ribbon.
07:02
We'll now add some annotations in the first thing we'll do is zoom up on the
07:06
base of the elevator pit and we're going
07:08
to call out the different materials within the slab
07:12
again, on the annotate ribbon, let's select material tag.
07:16
We'll begin by tagging the concrete so we can pick on this concrete layer here
07:21
and then place our our tag.
07:23
We also place another tag here for the blinding
07:29
and another one here for the damp proof membrane.
07:32
Notice here, if I move over the intersection between the concrete and the blinding,
07:37
you can see that we have a damp proof membrane.
07:39
So we'll place out our material note for that as well.
07:46
We'll now place down some additional tags which will
07:48
show us the thicknesses of the walls and the slabs
07:52
to do this.
07:52
We'll go back to the annotates ribbon and on the annotates ribbon,
07:56
we'll select tag by category on the options bar.
07:59
I'm going to remove the leader option
08:02
and we'll now begin by placing a tag on our six inch concrete slab.
08:06
We can then use the move tool to move the tag into a suitable location.
08:11
We'll do a very similar thing for the tag on the foundation at the bottom.
08:16
And again, we can tag our walls as well
08:21
to release the command. We can select to modify
08:25
if we want to rotate these tags here,
08:26
we can simply select the tag and then press the
08:29
space bar and you can see that will then rotate
08:34
and we can again move those into a suitable position.
08:37
Finally, we'll use a field region to designate Earth
08:40
to do this on the annotates ribbon. We'll select the region pull down
08:44
and we'll select a field region
08:47
on the context ribbon. Let's ensure that invisible lines are selected
08:51
and now we'll select the line tool,
08:54
we'll zoom in here
08:55
and we'll just draw a small area representing Earth. So here we can be fairly
09:00
abstract about how we show that.
09:04
And we'll close the sketch
09:07
and then again here, select finish edit mode
09:10
and you can now see we have our Earth represented.
09:13
Finally, we'll review the analytical model in the project browser,
09:17
double click on the analytical model.
09:19
And of course,
09:20
here you'll note that we have a very neat
09:22
and tidy analytical model with the required structural opening
09:26
the walls and also the foundation at the bottom.
09:29
So in summary, this is a very effective way to create an
09:32
photo
09:32
pit detail.
09:33
And you can see that we also get a valid analytical model.
