So, now that we've created our parts list, we're going to go ahead and create our pressure network.
00:11
So, in order to create a pressure network, what you have to do is you navigate to the Home tab of the ribbon bar,
00:16
drop down under Pipe Network and then navigate to the Pressure Network Creation tools.
00:22
If you had a object that you wanted to create a pressure network based off of, then you could use to Create Pressure Network from Object.
00:30
If you had an industry model, you could use that industry model to create pressure network from it.
00:36
We're gonna go ahead and use the Pressure Network Creation tools.
00:39
And then when we select that option, the Create Pressure Pipe Network window comes up.
00:44
We're gonna change our network name to Dev_H2O, because this is our water line for our development.
00:52
We're gonna use a parts list that we just created, which is 12-Trunk.
00:57
And then we are going to specify the target surface, which is important,
01:00
because our target surface tells our pressure network at what depth to be below a certain surface.
01:07
And so I know from our development profile that our EG surface, for the most part, is always underneath our development profile.
01:15
So, I can use the EG surface to dictate the depths on my pipe.
01:20
There is a small portion in here where it's slightly above the development profile.
01:25
And so if I wanted to, I could set my design depth a little lower to account for that issue right there and then I would have more than enough cover.
01:36
So, I'm going to go ahead and select EG as my surface name.
01:39
I'm going to go and not specify an alignment to associate this network with.
01:43
I am also not going to label any of the parts of the pressure network yet.
01:47
So, we're gonna go ahead and click "OK".
01:49
And what you'll notice is that the toolbar for pressure networks is different,
01:53
than the toolbars for everything else that we've done in Civil 3D so far.
01:57
This toolbar is locked up in the ribbon bar.
02:02
It's not a movable toolbar like all the other toolbars we've dealt with.
02:07
So, we have to work that up in here.
02:09
But it works exactly the same as any of the other toolbars.
02:12
So, we have a network settings area where we have our network properties, the surface we're targeting,
02:17
the alignment that we would be linked to, our parts list, and then our cover condition.
02:22
So, if I wanted to modify this cover condition from three, all I have to do is type in a number for my cover condition,
02:29
and then I would have enough cover in the areas where I might think that I could be having a problem.
02:35
So, I'm gonna go ahead and leave this as four.
02:37
I'm going to go over to the next area, which is, you select your material size, your pipe size.
02:43
We only offered a 12-inch pipe in our parts list.
02:47
So, that's the only option available for us in this dropdown.
02:51
From here, you have your Layout Methods, you have your Pipes and Bends, and Pipes Only.
02:55
Pipes and Bends is a better way to layout,
02:59
because it allows you to place the elbows that we put into our parts list at the time that you're placing the pipes.
03:07
If you use Pipes Only, you're only allowed to place the pipes based on deflection.
03:12
And so it doesn't work that well.
03:15
I much prefer Pipes and Bends.
03:18
So, we're gonna go ahead and go with Pipes and Bends method.
03:21
If you do a Pipes Only method or if you stopped in the middle of building a network and you need to start again,
03:27
you can add fittings to start that network over again or to add a missing part or something like that.
03:33
You can dropdown "Select the part you want to add" and then choose Add Fitting,
03:37
or dropdown, choose the appurtenance you want and then choose Add Appurtenance.
03:42
From here, we have the Modify section which has pretty self-explanatory modifying tools.
03:47
We have swapping parts, breaking pipes, moving parts, sliding parts, and then our Panorama Edit window for our network.
03:56
Next to that is the Compass and we'll show what the compass is when we're creating our network.
04:02
But just know that anything about the compass is in this area right here.
04:07
So, now that we have gone through this, we're going to go ahead and start laying out our pipe using the Pipe and Bends method.
04:14
And so what I'm going go ahead and do is, when you selected your pressure network creation tool,
04:21
it automatically jumped you into the Pipes and Bends method.
04:24
If you didn't want to use it, you could select Pipes Only or you can click on Pipes and Bends and it gets you out of the command.
04:30
So, I'm going to go ahead and click Pipes and Bends.
04:33
It's asking me to Specify First Pressure Pipe Point.
04:36
What I did is I created a line that I knew would allow me to have a nice 90-degree bend around this corner.
04:44
So, what I did is I laid out a line along the sewer line here and then I offset it up, I off set it down and out 10 feet,
04:53
and then I projected it at a 90-degree up to here.
04:57
So, I'm going to use this green line that's right in here and I'm gonna snap to the end of it.
05:02
And then I am going to come and follow along and snap to the end of it down here.
05:08
And so now what you get to see is you get to see the compass.
05:11
And so what the compasses is, it is a circle with tick marks at the locations of the bends that we have in our parts list.
05:18
So, we have our 90, our 45, our 22.5, and our 11, and our 0.
05:22
So, from these, you can lay out your pipes.
05:26
Since I set this up to be a 90, I'm going to go ahead and go with the 90 here.
05:29
I'm going to shoot down to this end down here.
05:33
And then I am going to click in.
05:36
And as you can see, I have the compass again.
05:40
I don't want to be going this way.
05:42
So, none of these other bends are going to work for me. I have to go with this 90.
05:45
But the problem is, is that this alignment isn't perfectly 90 in the corners.
05:50
And so you'll see my pipe is coming way out over here if I hit "Enter" to close out of that command.
05:59
I don't want to move these pipes around to try and get this to function better.
06:03
So, what I can do is I can force the deflection.
06:06
So, in this pipe, in your pipe parts list, if I go to Pressure Network and I got to Parts List and I go to 12-Trunk,
06:14
I will click Edit and I go to my Pressure Pipe and I go to my 12-inch pipe and I choose Edit on it.
06:21
What you'll notice in here is there is an allowable deflection.
06:24
That allowable deflection allows me to set a standard for how much this pipe can sweep or change from being perfectly 90 degrees into that fitting.
06:36
And so if I go to the Grip Edits for this pipe, what I can do is I can select this diamond grip right here,
06:42
which if I hover over it, you can see this as deflection.
06:46
I can select this and what Civil 3D shows me is it shows me allowable deflection.
06:50
So, out here at the yellow is my 5 degrees of deflection and then 0 degrees of deflection here in the center.
06:58
So, if I wanted to deflect this out, I could deflect it out to, let's say, that's one, two, three, four.
07:06
So, you could deflect onto 4 degrees and then click here.
07:09
And what you'll see happen is this pipe is now deflecting out this way.
07:13
And if I zoom into this fitting here, you'll see this pipe is coming in perfectly, 90 and flush with the face of this elbow.
07:23
But this one has a little bit of a deflection to it, and that's acceptable within the range of the pieces in my parts list.
07:32
So, now that we've laid this out,
07:35
we're gonna go ahead and move into the next video where we're going to take this network and we're going to put it into a profile.
