Splitting a Precast Panel

00:08

PRESENTER: Revit really gets into it now.

00:09

How about we do this?

00:11

Let's find some concrete walls, drill an opening into it

00:14

and split it into precast panels.

00:17

In Revit, I'll keep going with the medical center parking

00:20

garage.

00:20

I'm going to open my 05 model.

00:22

But if you're following along, of course,

00:24

just keep going with the same one you've been in.

00:27

Let's go to a 3D view.

00:29

So on the view control toolbar, click on the 3D view icon

00:33

right here.

00:37

Remember we set that path reinforcing to show up

00:40

unobscured in this view.

00:42

And there it is.

00:43

It's pretty cool actually.

00:45

Set my detail level to fine, because it's cool.

00:50

OK.

00:52

Now, let's come up to our elevator

00:55

shaft or our circulation area, I want to put a hole in this wall

01:03

here.

01:06

Zoom in on it.

01:09

Go to the Structure tab.

01:13

For opening, click Wall.

01:19

I'm just going to select this one wall here.

01:24

I'm just going to pick a nice box around it, like that.

01:33

Before I change anything about it,

01:35

maybe I'll change that top distance to three feet,

01:39

pushes the whole thing down.

01:42

Hit escape a couple of times.

01:45

Excellent.

01:47

Now, I'm going to select this wall, I'm going to hit Control,

01:50

I'm going to select this wall, that wall, and then that wall.

01:60

Go to your Precast tab, click the Split button.

02:09

In order to pursue this command, precast dependent families

02:12

need to be loaded.

02:14

What's going to happen, it's going to load a bunch.

02:17

It might throw a couple of errors

02:18

but those might be families that aren't pertinent to what

02:21

we're doing right here.

02:23

Click OK.

02:26

It loads a lot of stuff.

02:29

Now, it's splitting it.

02:31

This is where I might throw a warning or two.

02:38

Doesn't like those nooses, I knew it wouldn't.

02:41

That's OK, because those basically

02:43

don't go into this type of wall anyway, so let's

02:45

click Delete Type.

02:48

The lifters too, manual action required.

02:50

That's OK.

02:50

Because we're going to look at the configuration

02:52

in the moment.

02:52

Click OK here.

02:56

Look at what it did.

02:57

It split it.

02:59

OK.

02:60

Now, what we're talking about is let's click

03:02

on the Configuration button here.

03:05

Now that the stuff's loaded in, we can actually look at it.

03:08

Now, area reinforcement type, Rebar two layers.

03:13

Now, once we drill into this, we can click Edit.

03:19

We can change anything we want about it, a steel bar.

03:24

So for the inside and the outside,

03:25

we can change what those are going to be.

03:27

Actually, I'd like to change my Rebar type to number four

03:31

inside and outside.

03:36

Click OK.

03:39

And we can keep going through there.

03:41

Corner bars, I click Edit.

03:44

Here's how we're going to lap all of our corner bars.

03:47

Number of layers, one or two.

03:50

I'm going to stick with one.

03:52

Rebar type, I'm going to nudge that back up to number four.

03:57

Then click OK.

03:59

Go to L bars, I'm going to click Edit,

04:01

and I'm going to change my L bars number four as well.

04:04

Click OK.

04:09

Hit Escape a couple of times.

04:11

So there you go.

04:12

That's how you split walls up into precast panels.

04:14

It's pretty cool.
