Exploring cover settings

00:10

ERIC WING: It took me a while to get

00:11

used to the way Autodesk likes to do Rebar.

00:15

It always seemed pretty straightforward to me

00:16

that when you select the concrete element,

00:19

such as a floor or a column, you should have the choice

00:21

to simply turn on reinforcing.

00:24

Certainly, there are many different combinations

00:26

of reinforcing, ranging from placement to sizes to overlaps

00:30

and splices, but I would think there

00:31

could be a dialogue for that kind of stuff.

00:34

Well, there kind of is.

00:35

In this video, I'd like to explain

00:37

how Revit deals with typical reinforcing covers.

00:39

In Revit, I'm going to browse through.

00:41

I'm keeping my exercise files and I'm

00:43

going to open my structural model in the project browser

00:46

under structural plans.

00:47

And make sure you're in lower level.

00:51

Zoom in to column line two, I guess.

00:56

I like this area right here.

00:58

I'm going to cut a section right through this footing

01:01

and through this pier.

01:02

We're going to be moving it back and forth.

01:03

So on the Quick Access toolbar, click the Section button.

01:12

I'm going to put this section right on this column line here.

01:17

I'm going to resolve it right here.

01:21

I'm not a big fan of this line going right through this.

01:23

So notice that we have a little gaps in the Segment button,

01:27

we're going to click on that icon.

01:29

Notice that we can grab this grip

01:31

and drag it up, grab this grip and drag it down.

01:36

I'm going to pull in the extents a little bit.

01:39

Hit Escape a couple of times.

01:41

Now, let's double click on our section marker.

01:47

Not a big fan of the scale.

01:49

So for 1/8 inch, let's change that.

01:52

Click on 1/8 inch equals a foot.

01:55

Let's bump that up to

01:57

which is typical for concrete.

02:02

Now, I want to clean this up a little bit.

02:04

First thing I'd like to do is set my detail level to find.

02:09

That's going to join that.

02:10

Now, I want to go to modify.

02:14

Now click on the Join button right here.

02:17

Let's join our wall to our footing here.

02:23

Let's join R4 to our wall.

02:25

I like it.

02:26

OK, now, select any one of these concrete elements.

02:30

I'm going to select my wall here.

02:34

In our properties, let's scroll down till we find Rebar cover.

02:38

What we're seeing is how far from the face

02:40

do we want our Rebar to be so we get cover, so it doesn't rust.

02:45

We have exterior, three to five inches.

02:47

Interior-- Interior.

02:49

OK, good.

02:50

And if we click into this, we can change it.

02:54

OK, perfect.

02:55

Hit Escape a couple of times.

02:56

Now, how do we get to the Rebar cover settings?

02:60

So if we go to the Structure tab,

03:04

and we have Rebar over here, or I should say the Reinforcement

03:08

tab.

03:09

So if you click the Reinforcement tab dropdown,

03:12

notice that we have Rebar cover settings.

03:14

Go ahead and click that.

03:18

Now, here are all of our settings.

03:21

So any time you select an element,

03:22

these settings are going to show up.

03:24

So that's where it's coming from.

03:27

Click OK here.

03:30

You can save your project in that state.

03:32

I just wanted to show you how Ribar settings work.

03:35

Now, when we start adding reinforcement,

03:37

couldn't select any one of your elements.

03:39

Now, if we click on the Rebar button right here,

03:44

and we go to place it in whatever the default Rebar

03:48

shape is that you have, notice that we get these little dotted

03:51

lines that show up.

03:52

And Revit doesn't really want you to go past those.

03:55

That's our Rebar cover settings.

03:57

So in conjunction with our Rebar cover settings,

04:01

we can now place Rebar using those.

04:03

Also, when you automatically place Rebar,

04:06

it'll use those settings as a default. Hit escape,

04:09

save your model, you're all set.
