Modeling sloped piping in Revit

NARRATOR: Modeling sloped piping in Revit.

00:04

Sloped piping is necessary in plumbing design,

00:08

but there are additional things to consider

00:10

when you're modeling it.

00:12

In this video, we're going to create a line of sloped piping

00:15

for a sanitary system, and then we

00:17

will correct the view so you can see all the piping.

00:23

I'm working in the small Medical Center project.

00:26

And first, I want to create a sanitary plan.

00:30

In the project browser, I right click on the O1 ground floor

00:34

plumbing plan and duplicate it.

00:38

Then I'm changing the name to

00:52

Once my new plan is made, I'm going to Zoom

00:55

in on the exam rooms where I want

00:57

to add sloped sanitary piping for the exam room sinks.

01:05

In the System tab, I click Pipe.

01:11

Then in the modify fireplace pipe panel,

01:15

I'm clicking slope down.

01:21

After I select that, I select the slope value of 1/8

01:26

of an inch over 12 inches.

01:30

In the Options bar, I'm going to set

01:32

the diameter to three inches and then the middle elevation

01:37

to negative 1 foot.

01:42

Finally, in the type selector, I'm

01:45

going to set the pipe type to PVC, Python, DWV,

01:52

that drain, waste, and vent.

01:54

And then I'm going to verify that the system

01:56

type is set to sanitary.

01:60

I need to set the system type because I'm

02:02

going to draw a pipe that's not connected to any plumbing

02:05

fixtures.

02:09

I'm going to Zoom in, place my first point,

02:16

and then draw to the right and down outside of the building.

02:22

As I click outside the building, some of the pipe

02:24

is not showing, and a warning displays.

02:28

It tells me that I might need to check the active view

02:30

parameters, visibility settings, and plan regions.

02:36

I'm going to click Modify to stop my plump piping command.

02:41

And as I look around the view, I notice

02:43

that other sanitary pipes are not necessarily

02:46

showing as well.

02:47

I'm going to click on the 3D plumbing view

02:50

and say yes that sanitary piping exists for both sets of piping.

02:58

So this means the view range in the plan view

03:01

is not optimal for sanitary.

03:05

Back in the 01 ground floor sanitary plan,

03:08

I'm going to go to the Properties palette and select

03:12

the View range.

03:14

You can also type VR as a shortcut

03:17

to open this dialog box.

03:25

Let's talk a bit about the view range.

03:28

First, I'm going to click the Show button so you

03:31

can see the sample view range.

03:34

I find this very helpful when discerning which

03:36

items need to be modified.

03:39

Starting from the bottom of the key,

03:41

the number 7 is the overall view range from top to bottom.

03:46

It's made of your primary view range, which is shown is 5

03:52

and your view depth, which is shown is 6.

03:58

So this is a primary range here and the view depth there.

04:03

Your primary range is made of your top cut plane and bottom.

04:09

So each of these are available.

04:11

And then your view depth is below the level.

04:15

In this case, the top of the primary range

04:19

is set to the associated level, and then a height of 10 foot 8.

04:26

This is fine for the hot and cold water pipes

04:29

which are up in the ceiling, but we

04:31

don't need this high of a range for the sanitary piping.

04:36

So I'm going to change this offset to six feet.

04:41

When I click Apply, you can no longer

04:44

see the hot water piping because it is now

04:47

above the top of the primary range.

04:52

The cut plane right now is set to an offset of four feet.

04:57

Let's take a quick look at what happens

04:59

if I change that to one foot.

05:05

Oops, all the fixtures are gone.

05:08

We want to be able to see the fixtures, which

05:10

are at cabinet hype.

05:11

So I'm going to change the offset back to four feet

05:15

and click Apply again.

05:19

The primary range bottom and view depth

05:22

are our final options.

05:24

When I click on the list, you can

05:26

see that I can stay with the associated level,

05:29

change to the level below or select unlimited.

05:34

When you're working in the upper floors of a project,

05:36

you would set the view depth to one of these first two options

05:39

with an appropriate depth.

05:41

Since I don't know how deep the sanitary pipe is going

05:44

to be in this case and I'm on the lowest

05:47

level of the project, I'm going to click unlimited and then

05:51

click Apply.

05:54

When I click Apply, you see I get an error

05:57

because a view depth plane is said above the bottom clip

06:01

plane.

06:02

I have to make a change here.

06:04

So I'm going to click Close and also change my view

06:08

depth to unlimited.

06:12

And when I click Apply, you can see

06:16

that the full length of the sloped piping that I created

06:19

along with the rest of the sanitary piping in the model

06:23

is now available.

06:27

Once I know the deepest depth of the sanitary lines,

06:30

I will probably come back and change the view depth

06:33

to a specific distance below the level.
