Creating and modifying parallel pipes in Revit

MARTHA HOLLOWELL ORCUTT: Creating and Modifying Parallel

00:03

Pipes in Revit.

00:05

In this video, we're going to use the Parallel Pipes

00:07

tool to help us quickly add piping in a tight space.

00:11

Then we're going to align and move

00:13

the segments of the parallel pipes to fit the space

00:16

and avoid conflicts.

00:19

I'm working in the small medical center in the 3D HVAC view.

00:24

You can see that there are lots of ducts and pipes

00:27

that could be running into each other.

00:29

And while some of the piping is done,

00:31

I want to add liquid refrigerant lines from the main controller

00:35

here to the air conditioners along this side

00:38

of the building.

00:46

When I switch to the O2 second floor HVAC plan view,

00:51

you can see I've added one set of pipes to the farthest unit.

00:55

This piping run moves around other elements

00:58

and then connects into the controller.

01:02

The rest of the AC units have pipe coming from the unit

01:05

but are not yet connected to the controller.

01:12

This is where I want to add parallel pipe to the top

01:15

of the first run of the pipes.

01:18

Back in the 3D view, the first thing I'm going to do

01:21

is unlink the pipe I don't need to parallel copy

01:24

from the end of the pipe run.

01:27

Here near the air conditioner, I'm deleting the elbow.

01:30

This will give me more flexibility

01:32

in checking the pipe and then modifying it as needed.

01:36

Now I'm ready to run Parallel Pipe.

01:39

In the Systems tab, I click Parallel Pipe.

01:43

In the ribbon, I can now set up the array of the pipes.

01:47

I'm going to set the vertical number to five,

01:51

the horizontal number to one, and the vertical offset

01:54

to 1 and 1/2 inches.

01:57

The number of parallel pipes includes the existing pipe run.

02:06

When I hover over a pipe, you can see the array.

02:10

When I press Tab, you can see that it not only

02:13

selects the one pipe but the entire pipe run.

02:17

That's what I want, and I'm going to click to accept it.

02:22

Then I'm going to click Escape to end the command

02:25

and put me back in the modify command.

02:29

Now I need to clean up the intersections.

02:32

First, I'm going to clean up the original intersection

02:35

with the Trim to Extend to Corner command.

02:42

Next, I'm going to make sure that the elevation to the pipes

02:45

match up where I want them to be.

02:47

So I'm going to click Modify, select the second pipe up

02:51

in the run here, and I'm going to see that is the 10

02:55

foot 11 and 1/2 inches.

02:57

So I need to come here and change

02:59

my pipe that I'm connecting into it to that same height.

03:04

Now I can run Trim to Extend to Corner from that second pipe

03:09

to the pipe I need to.

03:11

I'm going to continue doing this for each of these pipe

03:15

runs down the way.

03:20

So here's my third pipe up.

03:22

Let's match that, 11 foot 1.

03:27

Trim Extend to Corner.

03:34

Pipe number four, let's set that to match

03:44

Trim Extend.

03:48

And finally, the last pipe on the top is 11 foot 4.

03:55

The corresponding pipe is also 11 foot 4.

03:59

So all I need to do is trim this one up as well.

04:04

The other tight space we need to work with

04:06

is closer to the controller.

04:12

I'm going to select both of the gas and liquid refrigerant

04:16

lines here.

04:17

So I'm going to grab these together

04:19

because I know there's probably or potentially

04:22

clash in this very tight space.

04:25

So in the Collaborate tab, I click Interference

04:28

Check, Run Interference Check.

04:31

And since all I've selected is pipe fittings,

04:33

that's what I'm going to check against each other,

04:36

and click OK.

04:38

Thankfully, there's just one clash.

04:42

Let's see where it is.

04:43

There's some of the refrigerant piping,

04:47

and there's the liquid refrigerant piping,

04:49

and we have this clash here.

04:52

So what I need to do is modify this group of pipes

04:57

so that they are closer together and will fit

04:60

underneath that existing pipe.

05:02

So I'm going to move the Interference Report dialog box

05:05

over to the side, so I can see better.

05:10

And then I'm going to open my Visibility Graphics dialog box.

05:14

And I had a gas refrigerant piping filter

05:18

that I could turn off.

05:19

Now I'm ready to work with these pipes.

05:22

I'm going to go ahead and select them, the ones that I don't

05:25

want right now, and erase them.

05:28

And let's get rid of those elbows as well.

05:30

They won't be needed.

05:32

And now I'm going to run the Parallel Pipe command again

05:35

on this one piece of pipe and put it closer together.

05:41

So I'm going to the Systems tab and selecting Parallel Pipes.

05:46

Once again, I'm going to set the vertical number to five,

05:50

but in this case, I'm going to change

05:51

the vertical offset to 1 inch so that they are closer together.

05:56

I'm then going to select my pipe and click to apply my pipe run.

06:02

Now I just need to come in here and clean up my pipe.

06:06

Oops, watch out.

06:06

Make sure you're picking it on the right end.

06:09

So I have to cancel out of that.

06:12

Pick it below.

06:13

There I am picking each of the pipes,

06:16

trimming extending to the corner, which

06:19

cleans up the elbows.

06:29

Type VV again.

06:31

Turn on my gas refrigerant tubing.

06:34

Now let's check the Interference Report.

06:37

Click Refresh.

06:38

Yes, we got rid of that overlap.

06:41

I can close that and move on to the last piece.

06:47

I know there is one last place that needs to be corrected.

06:51

So I'm going to go into the floor plan view,

06:55

and I'm going to turn off the gas refrigerant piping again

06:58

through filters.

06:60

So there's gas refrigerant piping.

07:02

Turn those off.

07:03

Get them out of the way.

07:04

Then I'm going to zoom in.

07:06

And you can see that, while my first pipe lines up with its

07:10

connecting point in the equipment,

07:13

the rest of them don't.

07:15

So what I need to do now is align these pipes

07:18

so that they will fit where I need them to fit.

07:21

So I'm going to the Align command.

07:24

I'm going to select the point, the node right here,

07:27

that's on the controller.

07:29

And then I'm going to align that with the pipe.

07:31

So there we go.

07:32

The pipe is getting aligned--

07:34

node to alignment, node to alignment,

07:37

each one down the way.

07:42

Now that those are aligned, I'm going

07:44

to go to the 3D HVAC view, and one last thing I need to do.

07:48

Again, let's get rid of those gas refrigerant

07:51

lines for a minute.

07:52

Click OK.

07:54

And I'm going to come in now, hitting escape

07:57

to get to Modify.

07:59

All I'm doing is picking on that last little point,

08:02

making sure that it's connected.

08:04

So it was right in line where it needed to be,

08:07

but it wasn't connected to the controlling machine.

08:12

So I'm going to click on each of those.

08:14

And now when I hover over this, press Tab,

08:18

you can see that they are all connected into the main air

08:22

conditioning unit.

08:26

As you can see, the Parallel Pipe tool

08:28

can save you time when you are working in tight spaces.
