In this video, we're going to create an alignment from a pipe network.
00:09
But before we can do that, we actually have to have a pipe network.
00:12
So what we're going to do is we're going to do a quick creation method with the pipe network so that we can create an alignment based off of it.
00:17
So we're going to dropdown Pipe Network, we're going to select Create Pipe Network from Object,
00:21
and we're going to zoom into the center line of our road that runs long north side of all of our properties.
00:26
I'm going to slit center line, polyline that was brought in by turning on the C-Road center line layer.
00:32
I'm going to select it, I'm going to accept the direction that it's running in.
00:36
And the only changes I'm going to make to this window is I'm going to choose a 24 inch concrete pipe,
00:41
and I'm going to change the structure to a null structure, and then I'm going to select "OK".
00:46
So now that we have a pipe network, we can create an alignment from it.
00:51
When we create an alignment from a pipe network, what you do is you dropdown the Alignment dropdown, you select Create Alignment from Network Parts.
00:58
Civil 3D asks you to select the first connected network part.
01:01
So we're going to go ahead and select this first null structure.
01:04
Then Civil 3D asks us to select the next network part.
01:09
So you could go and select this pipe and then move on to this structure and then move on to that pipe and then move on to this structure.
01:16
But inside of Civil 3D, if you select this last structure here,
01:21
it knows that this last structure is connected to that first structure by these three entities here, this pipe, that structure, and that pipe.
01:28
So I can select the first structure and select the last structure and it selects all the structures in between.
01:36
So what I'm going to go ahead and do then is now that I've selected all my structures, I'm going to hit "Enter",
01:41
and a creation window for an alignment pops up.
01:44
I can choose what site I want to put it on, what name I want to give it, what style I want to have, and what labels I want to place.
01:50
What you'll notice that we don't have available to us are the design criteria because this alignment is associated to this pipe network.
01:59
We know it's not going to be used for a creation method to create a road,
02:05
it's meant for displaying this pipe network in certain ways inside of Civil 3D.
02:11
Most often you're going to be using it to then create a profile view.
02:14
So we're going to go ahead and work through these options.
02:17
What you do have an option for is create profile and profile view when you create this alignment,
02:22
because generally what you're going to be doing when you create an alignment from a pipe network is you're going to be creating a profile,
02:28
and then placing that pipe network inside that profile view.
02:32
So we're going to go ahead and click "OK" and we get a Create Profile from Surface window and we can run through this.
02:39
We're going to go into this in more detail in another video,
02:42
but just know that you would select a surface that you want to have your surface profile cut from,
02:47
and you're going to click "Add" and then you're going to click "OK".
02:50
And so then we get a warning that says, the profile has been created,
02:54
but a window hasn't been created or profile view window has not been created to display it inside of, and that's okay.
03:02
But what we do now have is we have an alignment that's associated and it goes along the center line of this pipe network.
03:11
So what you can do now is you can select that alignment and what you'll see is you have the grip edits.
03:16
It's very similar to when we created our alignment from objects.
03:21
You'll see it's all the circular grip edits.
03:23
We have circular grip edits again.
03:25
There's no tangency to be maintained.
03:27
And actually what you can see here is there's a warning here that says tangency violated.
03:32
The alignment that was created for this, the tangency is incorrect between this line and that arc,
03:38
and so it's warning us, hey, there's not actually tangency happening right here.
03:43
So what we know is we don't want to go ahead and use this later for some form of roadway creation because we don't have tangency.
03:52
But we do now have an alignment that we can use to create a profile and profile view window for our pipe network.
