Hello and welcome to gravity pipe network interference
00:03
check.
00:04
My name is Stacey Morykin, design technology manager.
00:08
In this session, we will navigate and correct
00:10
the interferences created from the previous session.
00:14
We are now at the second and final step of the workflow,
00:17
navigate and correct the interferences.
00:19
So let's switch over to Civil 3D and get started.
00:24
You can use the same file from the previous session
00:27
or open the interference checks in Civil 3D, begin2.dwg file.
00:34
In the prospector tab of the tools base and our plan view,
00:38
there are two interferences denoted in the drawing.
00:42
There are also two profiles that show the sanitary sewer runs,
00:46
and the storm pipes have been projected onto the profiles.
00:50
Our interference check criteria is currently set to 5 feet.
00:55
First let's review the profiles to see
00:57
exactly how close these pipes are
00:59
at these specific locations.
01:02
In profile 1, click on the storm pipe crossing
01:07
and right click to edit the pipe properties.
01:11
In the Information tab, change the style to crossing storm.
01:26
The distance between the top of the storm
01:28
and the bottom of the sanitary is 4.9 feet.
01:31
This is very close to our 5 foot criteria,
01:34
so we want to modify the storm just
01:35
to drop it a bit so we are well outside the 5 foot criteria.
01:39
Let's first take a look at the rule for the storm pipe.
01:45
Under our basin 2, under our pipes, this is pipe 34.
01:54
If we find pipe 34, first, let's refresh just
01:58
to make sure that we're not violating any of the rules.
02:02
Underneath pipes, we find pipe 34.
02:10
Right click and go to the pipe properties.
02:15
In the Rules tab, you'll notice we are not
02:18
violating any of the rules.
02:20
Our minimum slope is a half a percent and our maximum slope
02:24
is 10%.
02:27
Underneath the part properties tab,
02:30
in the area of the pipe slope, hold start,
02:33
we will change this value to negative 1.
02:38
You hit Enter and OK.
02:43
Notice that because we have made a change to the pipe,
02:45
our interference check now needs to be rerun.
02:48
To rerun the interference check, simply right click
02:52
on the interference check and rerun the interference check.
02:57
Civil 3D now tells us that we have one interference check
03:00
that we still need to fix.
03:10
Going back to the planned view, we
03:12
see that the next interference is between catch basin 5
03:16
and catch basin 4.
03:18
So we will zoom back into profile 2.
03:22
This pipe number is 29.
03:24
So again, we want to ensure that we're not potentially
03:27
violating any of the rule set that we have for this pipe.
03:31
Under pipe 29, we will right click and go
03:34
to the pipe properties.
03:37
Under the Rules tab, you'll notice that our minimum cover
03:40
is violated, which means that we will need to drop this storm
03:43
sewer pipe even further.
03:46
If we drop it further, it will get closer
03:48
to our sanitary line.
03:50
So in this instance, we want to modify the sanitary line.
03:54
We'll click to find out the name of this pipe, which is pipe 40.
03:58
Underneath our sanitary sewer network, under the pipes,
04:02
we will find pipe 40 and review the rules.
04:08
Under pipe properties are rules that
04:11
allows for a minimum slope of
04:16
Our current pipe value is at 2%, so we do have room
04:19
to increase this slope.
04:22
Underneath the part properties, we
04:24
want to change our pipe slope, hold start, to negative 3%.
04:31
We'll go ahead and click OK and rerun our interference check.
04:39
Civil 3D now tells us that there are no interferences found
04:42
between these two networks.
04:45
Any modification to either pipe network from this point
04:48
forward would require us to rerun the interference check
04:52
and modify pipes as we go.
04:55
Now that we have no interference checks,
04:57
you want to make sure that you go back through your pipe
04:59
networks just to make sure that all of the pipes
05:01
are following the rules that you have established.

There are also two profiles that show the sanitary sewer runs,
00:46
and the storm pipes have been projected onto the profiles.
00:50
Our interference check criteria is currently set to 5 feet.
00:55
First let's review the profiles to see
00:57
exactly how close these pipes are
00:59
at these specific locations.
01:02
In profile 1, click on the storm pipe crossing
01:07
and right click to edit the pipe properties.

In the Information tab, change the style to crossing storm.
01:26
The distance between the top of the storm
01:28

01:31
This is very close to our 5 foot criteria,
01:34
so we want to modify the storm just

01:39
Let's first take a look at the rule for the storm pipe.
01:45
Under our basin 2, under our pipes, this is pipe 34.
01:54
If we find pipe 34, first, let's refresh just
01:58
to make sure that we're not violating any of the rules.
02:02
Underneath pipes, we find pipe 34.
02:10
Right click and go to the pipe properties.
02:15
In the Rules tab, you'll notice we are not
02:18
violating any of the rules.
02:20
Our minimum slope is a half a percent and our maximum slope
02:24
is 10%.
02:27
Underneath the part properties tab,
02:30
in the area of the pipe slope, hold start,
02:33
we will change this value to negative 1.
02:38
You hit Enter and OK.
02:43
Notice that because we have made a change to the pipe,
02:45
our interference check now needs to be rerun.
02:48
To rerun the interference check, simply right click
02:52
on the interference check and rerun the interference check.
02:57
Civil 3D now tells us that we have one interference check
03:00
that we still need to fix.
03:10
Going back to the planned view, we
03:12
see that the next interference is between catch basin 5
03:16
and catch basin 4.
03:18
So we will zoom back into profile 2.
03:22
This pipe number is 29.
03:24
So again, we want to ensure that we're not potentially
03:27
violating any of the rule set that we have for this pipe.
03:31
Under pipe 29, we will right click and go
03:34
to the pipe properties.
03:37
Under the Rules tab, you'll notice that our minimum cover
03:40
is violated, which means that we will need to drop this storm
03:43
sewer pipe even further.
03:46
If we drop it further, it will get closer
03:48
to our sanitary line.
03:50
So in this instance, we want to modify the sanitary line.
03:54
We'll click to find out the name of this pipe, which is pipe 40.
03:58
Underneath our sanitary sewer network, under the pipes,
04:02
we will find pipe 40 and review the rules.
04:08
Under pipe properties are rules that
04:11
allows for a minimum slope of
04:16
Our current pipe value is at 2%, so we do have room
04:19
to increase this slope.
04:22
Underneath the part properties, we
04:24
want to change our pipe slope, hold start, to negative 3%.
04:31
We'll go ahead and click OK and rerun our interference check.
04:39
Civil 3D now tells us that there are no interferences found
04:42
between these two networks.
04:45
Any modification to either pipe network from this point
04:48
forward would require us to rerun the interference check
04:52
and modify pipes as we go.
04:55
Now that we have no interference checks,
04:57
you want to make sure that you go back through your pipe
04:59
networks just to make sure that all of the pipes
05:01
are following the rules that you have established.
Interference checking lets you quickly identify pipe network parts that may conflict with each other. This features inside Civil 3D compares the actual 3D Model of the pipe network to identify parts that physically overlap, collide, or intersect in an inappropriate way, or that have violated the predefined, proximity-based criteria.
Profiles were created in the drawing to view the interferences easier.
Review the profile to see Pipe - (34) crossing is 4.9 feet below the Sanitary line. Since the criteria set is 5 foot, we will need to modify the storm pipe slope to increase the distance of separation beyond 5 foot.
The new number of interferences found now equals 0.
