Getting Started Modeling Pressure Networks in Civil 3D
Summary
TLDRThis video walks through modeling pressure networks in Civil 3D. It starts by showing how to build a parts list from catalogs to represent components used in designs. It then demonstrates creating pipe runs, which function as branches in a network, based on an underlying alignment and profile. Additional topics include connecting runs, adding fittings like valves, editing geometry and elevations, and labeling components. The presenter shares links to other Civil 3D resources for further learning about pressure networks.
Takeaways
- 😀 You can create a parts list to hold commonly used pressure network components, rather than using the full component catalogs.
- 👉🏼 Pressure networks in Civil 3D 2021+ use pipe runs, which are built on underlying alignments and profiles for easier editing.
- 🔧 Pipe runs in a network can be connected, and you can have multiple pipe runs within a single network.
- ⚙️ The pipe network compass allows you to snap to available bend angles when laying out pipe runs.
- 🔧 You can add or remove bend points and fittings along a pipe run.
- 📏 Pipe run profiles make it easy to edit pressure networks vertically, including creating grade breaks and lowerings.
- 📐 You can create pipe runs that automatically offset and parallel existing alignments.
- 🛠 The content catalog editor allows you to customize pressure network component properties like descriptions.
- 🔀 Pressure pipe labels can display component properties like nominal diameter and description.
- 📚 Additional resources are available for customizing catalogs and assigning pay items to pipe networks.
Q & A
What is a parts list in Civil 3D and why is it useful?
-A parts list in Civil 3D is a subset of components from the available part catalogs that come with Civil 3D. It contains the specific parts like pipes, fittings, and appurtenances that are most commonly used for a particular project or organization. Using a parts list streamlines the design process by only including the relevant components.
How are pipe runs different from previous versions of Civil 3D?
-In Civil 3D 2021 and later, pipe runs are built on an underlying alignment and profile. This makes them much easier to edit both horizontally and vertically compared to previous versions where pressure networks were built just as a collection of individual components.
Can the pipe run feature be used for utilities other than water networks?
-Yes, the pipe run feature does not have to only be used for pressure networks. It can be used to model other buried utilities like gas mains or fiber optic lines that also require a certain depth below ground.
How can pipe run elevations be edited vertically?
-The elevations and cover depth of pipe runs can be easily adjusted using the profile view. Profile grips allow the PVI and grade to be edited. Lowerings can also be created by overriding elevations or creating an additional profile.
What grip editing options are available for pipe runs?
-In plan view, pipe runs can be grip edited like alignments using the square grip, compass grip, and arrow grip. These allow for continuing the run, inserting or removing bends, and lengthening/shortening. Pipe run profiles also have PVI grips in profile view.
How are fittings determined along a pipe run?
-When a pipe run is created, the available bend angles displayed in the compass are determined based on the fittings included in the parts list. The software automatically places the appropriate closest fitting based on the angle snapped to in the compass.
Can additional fittings like valves be added to an existing pipe run?
-Yes, fittings like valves and hydrants can be added directly to an existing pipe run using the Layout Tools on the contextual tab. The pipe run can then be viewed in 3D to see the complete model.
How can pipe runs be created dynamically based on existing objects?
-The 'Create Pipe Run From Object' tool allows alignments, polylines, feature lines or other objects to be selected to dynamically build a new aligned pipe run based on that object's geometry. Offsets can be specified as needed.
Can multiple pipe runs be connected into one overall network?
-Yes. A pressure network can contain multiple pipe runs that function as branches. Runs can be connected by adding branch fittings that join them together, maintaining proper elevations.
Where can I learn more advanced techniques for pressure networks?
-The presenter recommends exploring Autodesk University classes like Charlie Ogden's 2021 class on the topic. There are also Civil Immersion blog posts and videos linked in the presentation notes that cover more advanced workflows.

😀 Introducing the agenda and overview
The instructor introduces himself and provides an overview of the agenda for the session. Key topics to be covered include creating a parts list, using the parts list to develop a pipe run, connecting pipe runs, editing the underlying alignment and profile, and additional resources.
😃 Building a parts list
The instructor demonstrates how to build a parts list by selecting a catalog, adding materials, sizes and types to create a subset of components that will be used to model the pressure network. Parts lists represent frequently used items and are saved in templates.
😊 Creating the first pipe run
The process of creating the first pipe run is shown, including selecting the parts list, cover depth, reference alignment and drawing the pipe run geometry. Labels are added and editing techniques using the underlying alignment are demonstrated.
😏 Adding additional pipe runs
Methods for adding additional pipe runs to the same network are covered, either through the contextual ribbon or the Prospector tree. Techniques for connecting pipe runs with appropriate fittings are also shown.
🤔 Editing pipe run properties
The process of editing pipe run properties like styles and descriptions is shown by selecting the pipe run and pertinent properties. An introduction to editing catalog properties through the Content Catalog Editor is also provided.
😮 Drawing pipe runs from objects
The creation of pipe runs from existing objects like alignments and polylines is demonstrated, including offset distances and elevations. The runs are connected and additional components are added as needed.
😲 Editing pipe runs in profile view
Techniques for editing pipe runs in profile view are covered, including measuring elevations along pipe lengths versus at bend points. The use of profile overrides to create deviations and lowerings is also shown.
🤯 Advanced lowering and crossing techniques
More advanced methods for creating crossings and lowerings are demonstrated, such as creating a Civil 3D profile to follow. The application of overrides and editing with PVI grips is also covered.
😇 Resources for learning more
Useful resources for learning more about pressure networks are shared, including Autodesk University classes and blogs. Questions from users are also invited.

Highlights
Parts lists represent a subset of components from installed catalogs to use for pressure network design
Parts lists are organized into pipes, fittings like elbows/Ts, and pertinances like valves and hydrants
Pipe runs are new in Civil 3D 2021+ and are built on underlying alignments, making editing easier
Pipe runs represent branches in the overall water network; we can connect multiple runs
We can create pipe runs manually, from existing objects like alignments, or using the compass
The compass allows snapping to available bend angles from parts list during piperun creation
We can edit pipe elevations easily since runs have alignment/profiles with PVI grips
Overrides tab allows holding manual elevation edits while allowing dynamic updates elsewhere
We can create pipe lowerings using alignment grips or by creating an override Civil 3D profile
Pressure network parts use styles from the parts list to control appearance in views
The content catalog editor allows editing part properties like descriptions used in labels
Surface profile created with pipe run maintains dynamic link if surface changes later
Cut length profile measures cover depth at each pipe cut length instead of just bend points
Add bend PVI option places appropriate fitting at grip location instead of just deflecting pipe
Pipe run functionality can be used for things like gas mains and fiber optic lines too
Resources include Civil Immersion blog posts and Autodesk University recordings

Transcripts
welcome my name is Jeff Bartels I'm an
infrastructure technical specialist here
at Autodesk and today we're going to
look at how we can get started modeling
pressure networks in civil 3D on screen
you can see the agenda for today's
session
we're going to start out at the
beginning we'll look at how we can
create a parts list the parts list is
used to hold the pressure Network
components that we will use to model a
pressure Network Parts lists represent a
subset of the overall collection of
components that come with all of the
part catalogs that are installed with
civil 3D we'll look at how we can use
the catalogs to build a parts list for
our project we will then look at how we
can use that parts list to develop a
pipe run the pipe run methodology is new
to civil 3D 2021 and above prior to
civil 3 2021 pressure networks were
built just as a collection of individual
components being that our pressure
networks are now considered runs they
are built on an underlying alignment and
profile which makes them much easier to
edit both horizontally and vertically
once we learn how to create pipe runs
we'll look at how we can connect pipe
runs together because you can have
multiple pipe runs within a pressure
Network we'll also look at how we can
edit that underlying alignment and
profile to modify the horizontal
geometry of the piperon as well as the
vertical and the event we want to create
lowerings and things like that and then
finally if you'd like more information
about this topic I'm going to leave you
with some additional resources
now I have to admit I'm not a big fan of
PowerPoint so instead of showing a bunch
of screenshots and bullet points and
discussing Theory instead we're going to
work live within the application
so I'm going to drop out of this
as you can see I am working in
simple3d2023.2 having said that the
majority of what we look at today is
going to work for you so long as you're
using civil 3D 2021 and above the reason
I say majority is because the new Piper
on functionality came out in 2021 and
since then there have been some minor
tweaks to the workflows so depending on
the version of civil 3D you have between
2021 and 2023.2 you may see some minor
nuances in the workflows okay we're
going to start out by building a parts
list we build a parts list from the
available part catalogs that civil 3D
comes with to build a parts list we
first have to start by selecting the
catalog
here on the Home tab in the create
design panel I'm going to expand this
and I'll choose set pressure Network
catalog
and if I expand this you can see the six
catalogs that come with civil 3D
consider these a starting point it's
kind of like you're going shopping for
the parts that you'd like to use for
your pressure Network I'm going to start
with the push on catalog and I'll click
ok
now to build a parts list from that
catalog I'm going to go to the settings
tab and then I will expand pressure
Network and if I expand Parts lists
you'll see there's I've got a parts list
in here already I'm going to create a
new parts list just so we can
demonstrate that I'll right click on
Parts lists and I'll choose new
and on the information tab I can give
this parts list a name I'll call it my
parts list down below you can see the
catalog that we are shopping from for
our pressure Network components when we
build a parts list it is organized into
these three tabs pipes fittings and
apertnesses
pipes represent pipes of various
diameters and materials fittings
represent the items that connect pipes
together like elbows T's crosses things
like that and pertinances are the other
items like gate valves air release
valves hydrants pumps things like that
so let's build out our parts list I'm
going to start here on the pipes Tab and
then I will right click on the new parts
list and I'll choose add material
and within the catalog that I'm looking
at the push on catalog you can see that
I only have one material I kind of think
of material as a family I'll choose
ductile iron I'll click OK I've just
added that material or that family to my
list now we'll add some sizes if I right
click on this I can choose add size
and notice in the dialog box we can see
the nominal diameter by default here is
four inches if I click inside this field
a couple times you can see the various
sizes that I can select so I can choose
the individual sizes I want and I can
click ok to add them to my parts list or
since we don't have a whole bunch of
them in here I could just say add all
sizes
note before I do that there are some
other items here that are editable I
could adjust the cut length here so that
it's a little bit different than what's
coming from the catalog I can also
adjust the allowable deflection if I
wanted to we'll look at some ways to
edit the part catalog in a little bit
for right now let's just add all the
sizes I'll click OK and if I expand this
you can see here's the sizes that I
brought in with respect to the ductal
iron family here's the sizes and then
I've got a column for the style the
style is what controls the appearance of
these pipes when they're viewed in plan
profile cross-section or in the 3D View
we also have a column for render
material if we want to assign that and
we have a column for pay item in the
event you have a pay item list
associated with your civil 3D file you
can apply the various pay items to these
components such that as fast as you
create the pipe runs and pressure
networks you'll be able to extract a
summary of quantities
let's go to fittings
I'm going to right click on the list and
choose add type
and you can see I have three types or
three families in here crosses elbows
and T's I'll click ok
and if I expand this I have added those
families to my fittings tab I can then
right click and add sizes just like we
did with pipes when it comes to the
elbows we have the nominal diameter you
can see that we have several to choose
from I also have several Bend angles to
choose from
since there's not a lot of them in here
I'm going to click add all sizes and
I'll click OK if I expand the elbows now
you can see my elbow options depending
on the the number of items that you need
to pull in here if there's certain
diameters that you typically don't go
above
might not be bad rather than just going
through and picking all of the smaller
ones you can always delete if you right
click you can choose delete likewise if
you select one of these hold your shift
key you can select a grouping of them
and you can delete them in bulk
okay so not bad to add them all you can
just delete the ones that you don't want
and we would go through this same
workflow for T's and Crosses we'll just
say at all sizes
and you can see all the t's because you
could do the same thing assign the style
render material pay item let's go to a
pertinances
I'm going to right click on a pertin it
says add type and with this particular
catalog I have just a couple of valve
families I'm going to add both of these
just so that we can see what those look
like
let me right click and I'll choose add
size and I can see for the 150 psi
family I pretty much just have three
size choices
there they are
and size
got quite a few more I don't know six
eight and twelve
there we go you can see the sizes for
those
now we don't have to limit ourselves to
pulling components from a single catalog
if I go to the information tab
I can come down and load a new catalog
for example let's choose the PVC catalog
and I'll click open
note that this catalog is loaded
but it's not yet in use I have not
pulled parts from this catalog and put
them in the list
that's why this one says in use and it's
locked I can't unload a cataloged word
Parts have been pulled into the parts
list okay that's the difference between
the icons here
if I go to fittings for example
let's clap some of these if I right
click on the parts list and choose add
type if I select the PVC catalog you can
see that we have additional options
things like reducers and plugs and T's
and caps let's add the reducer family
there
and then I can add sizes okay workflow
is similar
if I go to a pertinances
if I right click on the parts list and
go to add type if we go to PVC you can
see that this particular catalog also
includes hydrants that are organized by
their
very depth okay so we can create a parts
list or a subset of all the components
of all of the catalogs the parts list
represents the parts that we typically
use on our projects Parts lists are
saved as part of your template that way
when we create new designs we have the
parts that we use most often you can
always go and add to a parts list later
by having the parts list we are not
having to carry the full weight of all
the catalogs when we're doing our design
selection okay
I'm going to cancel out of this because
I've already got a parts list here let
me right click and I'll go to edits I
just want to show you what's in here
on the pressure pipes tab you can see
I've just got the sizes for ductile iron
I have
several sizes for elbows crosses and T's
and under pertinences
I've got those two gate valves and I've
got a hydrant in here as well
okay so my parts list has been created
if I would like to draw a pressure
Network here in the crate design panel I
will expand the pipe Network menu item
and I'll choose pressure Network
creation tools
this is the command that I run to not
only create a pipe run but this will
also create a brand new network since I
have not drawn any water main in this
project so far I'm going to use this to
create the new network I will call this
water
I will then give my piperun a name
we'll call it my first
run
I can select my desired parts list when
you choose the parts list you can then
see the available pipe sizes I've only
got the one family if I have multiple
families I could choose from those
I'll choose the eight inch size here's
where you could select your layers the
object layers for the various components
of the pressure Network you can select
these or have them chosen in the
template or you can take and assign
those yourself I'm just going to keep
the defaults in this case
the reference surface when we place the
pressure parts we want those to have a
particular depth below ground so what
surface do you want to measure that from
this surface right here is called demo
so I'll choose that I would like to
create a surface profile to follow the
demo surface this profile will be used
to edit the elevations of the pipes
later so I want to do that and I also
want that to be dynamic to that surface
that will happen automatically
for the cover depth I'm going to set
this to five and a half feet that's
typical for Illinois where I'm at the
reference alignment I don't have an
alignment in the adjacent area here but
in the event you were placing this water
main parallel to a roadway alignment and
you wanted the station and offset labels
of your water main to be tied to a
particular alignment here's where you
could select that alignment I could also
choose if as I draw this if I would like
to automatically label the pipes the
fittings and the apertnesses I'm just
going to leave those turned off for
right now and I'll click ok
and then I can draw my pipe rotten much
like I can create a polyline I clicked
my first point on screen civil 3D then
finds the elevation of that demo surface
and it drops down five and a half feet
I can then click my next point and then
it displays this Compass this Compass
allows me to snap to the available Bend
angles defined by the parts that are in
my parts list in my parts list I have
elbows with an 11 a quarter the 22 and a
half 45 and 90 degree bends in the event
your parts list only had elbows that had
90 degree bends those would be the only
snap options that you would see
so I just want you to understand where
the snap angles are coming from
let me pick a couple more points here
when I'm finished I'll press enter and
you can see that my pipe run is created
and the applicable elbows are placed
based on the snap that I was using on
the compass now I would like to label
these I'm going to go to the annotate
ribbon Tab and I'll click the price tag
here for the feature I will choose
pressure pipe Network and I would like
to label a single pressure part in the
plan view let's just label these elbows
I'll zoom in and I'll click this one
this one
and this one and you can see how those
were placed based on my snap I've got
nice
dimensions on those
if I select
the pipe run you can see that the grips
are very similar to what we see with an
alignment that's because it's built on
an underlying alignment in fact if I
right click you'll see alignment
properties here
if I may press Escape if I hover over
these Pi grips we see the same alignment
properties the reason why this is nice
if I click one of these grips and I make
an adjustment
you can see how the angles of the elbows
will update it will take and add the
appropriates closest elbow based on the
adjustments that I'm making
in addition to being able to drag these
Pi locations I can also insert new ones
if I come back to my contextual ribbon
here
there's an option to add a Bend pi
I can click where I'd like to place the
bend
not only does it place the band that
places the appropriate fitting let's
take and drop a label
on that
so 22 and a half
and then as I drag this we'll see how
that elbow changes in addition to adding
the pis we could take them away so you
can see I can choose remove Bend Pi if I
click near this
it takes away the pi and it takes away
that fitting
let me press escape a couple times
let's look at another thing
maybe I would like to add a valve along
this line
here in the layout panel
I will open up a pertinence because
that's where the valves are located this
is an eight inch pipe so I will choose
eight inch gate valve and I'll click add
a pertinence I will then move my cursor
close to this pipe and you can see the
boxing gloves or the glyph that shows me
that if I click it's going to add that
item to this line
if I zoom in
note that if I click this pipe run one
time I get access to these alignment
grips
so if I move this
historically in older versions of civil
3D it would pivot right here at the
valve it no longer does that these
valves now stay in line if I select this
pipe run a second time this gives me
access to the individual components
that's the trick now that I've selected
this a second time you can see I've got
the grip here on this
valve if I click this once and then
twice I can right click and here's where
I get access to the apertness properties
style I can swap these out things like
that
okay let's come over here let's say I
wanted to add another pipe run
we can have more than one pipe run in a
pipe Network
so since my contextual ribbon is open I
can add another pipe run by simply
opening the menu here and choosing
create new pipe run
let's do this though let's assume the
contextual ribbon's not on screen if you
remember when I drew this pipe run I
opened a pipe Network and I said
pressure Network creation tools
this option creates the pipe run but it
also creates a brand new network I don't
want to create a brand new network I
want to create multiple runs under the
same network think of a pipe run as
being kind of a branch in the overall
Network so I would like to make these
all part of the same network so I won't
use that option again if I would like to
add a new Piper on I can select an
existing pipe run
which will bring back the contextual
ribbon and then from here I can add a
new pipe run or
second way if I go to the prospector tab
if I expand the pressure networks
category and expand my network
right here we can see the pipe runs that
are in that Network just have the one if
I want to add another Piper on I can
right click right here and I can say add
pipe run
I'm going to do that you can see it's
adding that Piper onto the same network
I'll call this my second run and give it
a description you can see it's keeping
the same settings what we had before
let's do a different diameter this time
maybe 14 inches and then same demo
surface five and a half feet below let
me click OK and then I will click maybe
here and then we'll click here and
that's as far as I want to go I'll just
press enter so I've got a 14 inch pipe
maybe I would like to make a connection
if I select this first pipe run you can
see I have three grips if I click the
square grip at the end it's much like
I'm grip editing it in alignment okay if
I bend this it will change the elbow
if I click the plus it will bring up the
compass and it will allow me to continue
on and it will also place a fitting
there for me
if I click the arrow I can use this to
lengthen or shorten this pipe if I pull
this out such that I get close to this
pipe you can see the boxing gloves there
let me click and it places the
appropriate fitting now what if these
pipes were at different elevations in
the event we're working with a t it will
hold the elevation of the through pipe
the connecting pipe the elevation would
adjust to meet the elevation of this
through pipe
let's do this I'm going to click the
script and I'll pull it back what if we
had a Crossing let's drag this over
in the event we had a crossing and we
wanted to add a cross connector here
I can do that using this add Branch
fitting option
if we're dealing with a Crossing it's
going to ask me to select the pipes in
the order based on which depth you want
to hold so it says select first pipe and
intersection if I click this pipe first
that's the depth that's going to hold
when I click the second pipe that's the
pipe that it's going to edit
to insert my connector
okay let's apply a label to this just
want to show you a little trick here if
I select this once and twice there's my
cross I'm going to come over to the
properties palette for a second notice
the nominal diameter description we can
see that listed here can't change it
okay it's grayed out
let's say I'd like to label that part
that's a fitting now I'm labeling it
with a t but really T's and Crosses are
going to have the same label Style
I'm going to click add and then I will
click this object
and then I will click the label and we
will click the script and we'll pull it
out
as you can see the label style that's
used for this particular cross it's
labeling that nominal diameter
attribute
okay
if I I think I can close this now if I
select this cross
and go to the properties palette once
again I can't change that the label's
fine it's accurate it's just a little
bit longer than I would like maybe I
just like this to be cross 14x14 X8 X8
so I really can't edit that here you can
see that there is a description here
it's actually even longer that describes
this part and this is you can see I can
type in here this is editable okay so if
my label style pointed to the
description I could manually edit that
text here but I don't really want to do
that for every single fitting and a
pertinence an item in my pressure
Network so let me show you a shortcut
I'm going to come down and click the
Windows button and then I will select
Autodesk civil 3D 2023
inside here you'll find an application
called content catalog editor this is
installed with civil 3D this is used to
edit your pressure Network catalogs if I
go to open
you can see the same catalogs that we
saw earlier
now in the event you don't see these
right off the bat when you go into the
application I just want to show you the
folder where these are stored program
data Autodesk c3d 2023 enu pressure
pipes catalog and I'm looking at the
Imperial version there's also a metric
version
let's choose the push on catalog for a
second and I'll click open and when I
open the catalog we can see the families
if you will that have content if I
expand the cross you can see the two
families there 350 is what I think we're
looking at and if I open up this this is
where I have access to that description
okay
editable so I can make these say
whatever I want
if I drag this over
if I drag this over you can see the
nominal diameter
these are editable notice the number of
attributes in here that are unpopulated
currently everything from Branch angle
to ID coding inside coding outside
schedule SDR series strength class all
of the items if you go through here and
populate these these are things that can
participate in your labels
so they're they're not heavily used in
the catalog right now but if you wanted
to you could go through and edit the
values here and add to them to have even
more power with your labeling
having said that I'm not going to make
the changes here right now
I don't even think it would let me save
my catalog in this case because the
catalog is already it's it's in use
right now in this drawing I would likely
have to close out of civil 3D in order
to be able to save this because this may
be in a read-only state at the moment
but that would be a shortcut if you edit
the properties in your catalog and then
build your parts list from that that
will help you with your labeling in the
future in the additional resources that
I'm going to give you at the end of
today's session there will be a Autodesk
University recording that provides
demonstration for how to edit your parts
catalog and even more hyperlinks that
will show you more hardcore ways you can
get in and make changes to your catalogs
so I just want to show you that that's
there let me get out of this
okay now that we understand how the pipe
runs feature Works let's look at how we
can use it in a practical example I'm
going to zoom out and on screen we have
a portion of a subdivision
and if I hover you can see I've got a
surface here called composites
for some of these roads anyway like the
roads through here I've got a proposed
Road surface and I've got that pasted
into the existing ground surface that
pasting was used to create a composite
surface that way I have one surface for
the entire thing now I don't have a
proposed surface for this roadway yet
this road I think is called East Court
that's all right for this example just
wanted to mention that the surface that
we're using
if I'm going to create a pipe run along
this my contextual ribbon's still open
let's go to add piperon great pipe run
I'm going to call this
East Court water main
parts list is going to be water 8 inch
surface I'm going to come down from the
composite surface five and a half feet
reference alignment in the event I
wanted to label these components with
stations and offsets to the center line
of the roadway I can choose that
alignment here click ok
and now I can draw my components using
that compass
so I'll come down here and click and
when the compass is up on screen if we
go up to the contextual ribbon and
expand the compass panel right here we
can control the color of the compass and
the diameter in the event this is a
little bit bigger than you would like
notice there's an option to turn the
visibility of the compass off there's
also a snapping feature here we can turn
the snapping off back in the old days
this was very rigid you could only snap
to these predefined angles problem being
I'm allowed a certain amount of
deflection at each one of these angles
and it just didn't allow me to do that
if I turn the snapping off I can see the
angle still but I can kind of deviate
from that a little bit
make things easier maybe we'll go here
and then maybe I'll take this down
to here
when I'm finished I'll press enter
so there's my water main works just like
the other one I could select this I
could grip edit it I could label that
the pieces would update
maybe I'd like to add a hydrant we saw
how we could connect to a piper on I can
also connect from a pipe run
we'll create another one great new pipe
run
I will call this
hydrants
zero one you can name these whatever you
like
once again think of each run as being a
branch in the overall Network I'm going
to go with a six inch pipe same surface
same cover same reference alignment let
me click OK I will then click to start
at this pipe and we'll take this towards
the property corner here
and I'll press enter
it automatically puts the appropriate T
in there maybe we can add a six inch
valve now add a pertinence
so I can drop that in and then we'll
expand this and I will add a hydrant
perfect once it's been added let's take
a look at it in 3D I will click once
which gives me the alignment click it
again which gives me the hydrants and
the pipe and this valve I'll right click
and choose object viewer
and then we can tip this up
and view it in 3D
so you could add additional valves or
pertinances whatever your design
requires
that's basically what the workflow looks
like now in addition to creating
pipe runs based on the compass or
drawing them manually we can also create
pipe runs that are based on existing
geometry this will work with an
alignment a polyline or a feature line
let's assume I would like to create a
pipe run that is parallel to this
roadway West Street
I'm going to come up to the textual
ribbon and I'll say create pipe run from
object
I will then select this alignment
and remember the pipe runs are built on
an underlying alignment so we're going
to see a lot of the same options that we
have when we create an alignment I've
got the direction there I'll say that
that's okay
creating this pipe run under the same
water Network we're going to call this I
think it was called West Street let's
come down here yeah West Street so my
reference alignments if I'm labeling the
station's offsets is going to be the
same one so let's come up here
piperon is going to be called West
Street water main
we'll go with an eight inch pipe
we're going to be going under the
composite surface
we're going to create that surface
profile now a horizontal offset distance
since I'm building this pressure network
from an existing object if I leave this
set to zero it's going to put it right
down the alignment I can put a positive
or A negative number here to create an
offset negative number we'll put it to
the left and it's based on the direction
of the piperon not necessarily the
direction of the roadway alignment we'll
see an example of that here in a little
bit in this case they're both running in
the same direction so if I want this to
the left I will say negative eight feet
cover five and a half feet now since we
are building this pipe run from a
selected object in the event that object
was at elevation like a feature line I
could come down here and say use a
Vertex elevations and I could say that
feature line represents the outside top
the crown the center line you can see
some of the other options here for right
now I'll just choose the cover of five
and a half feet and I don't want to
erase the existing object I'll click ok
there's my pipe run
let's create one for this roadway this
is Long Street now with Long Street the
stationing is coming from the east to
west
I'm going to create another pipe around
here
create it from object
notice the direction it doesn't have to
be the same direction so I can have this
going the other way let me click OK
we'll call this
long straight water main
and then
I want this to tie
to the Long Street alignment center line
alignments I would like to put it to the
left
so this is based on the direction the
pipe run goes so I'll say negative eight
feet to put it on this side
click ok
and then I can click here grab the
triangle I can pull this over and make
my connection I can now go through and I
can add additional Pi locations I can
add valves and pertinances wherever I
need them to finish building out my
water main design
so we've kind of talked about how we can
do this from a horizontal perspective
let's talk for a second about vertical
for the vertical we're going to look at
the example here I've got this pressure
Piper on East Court water main when we
draw or when we create a pressure
Network the elevations by default of the
cover depth is measured from all of the
endpoints or the bend Points each place
that you click
see that I'm going to select the piper
on and then from the contextual ribbon
if I wanted to draw this in a profile
you can see that we've got the classic
option here draw parts and profile view
so we can still do that we also have
this pipe run profile but this allows me
to create a pipe run profile view write
down the utility itself
and there's the pipe run Name by default
it's going to be doing the offsets at
the bends here's the reference profile
that's the surface profile composite
that's going to be maintaining that
Dynamic relationship with in the events
of the composite surface changes the
elevation of this water main will update
as well
and I would like to draw that in a new
profile view so this pipe run offsets at
the bends which is what it is currently
it's using the same composite
and let's draw it in a new view let me
click OK since I'm drawing a new view
it's going to be creating a profile view
just like it does for other profile
views I do want to make a couple edits
here if I go to profile display options
you can see that there will be two
profiles displayed in this view there
will be the profile that represents the
grips that I can use to edit this
vertically notice there's no pipes
options in here the appearance of the
pipes is going to be based on the styles
that are assigned in your parts list and
then this is the profile of the existing
ground I'd like to draw both of those
and then I'm going to come down I want
to change the profile style for the
ground
and I don't need labels on these so I'm
going to select both of those and I'll
click and I'll say take away the labels
now if I do come down to pipe pressure
Network I can see here's where I can
select the pipes and the fittings and
the importances that are going to
display in this view once again though
the appearance is controlled by the
styles that are assigned in the parts
list
let's just create profile view and I
will click over here
so there's that pressure Network
Underground
if I select this one time just like we
saw in the plan view if I select it one
time you can see the profile you can
kind of see that magenta line that is
the style of that profile I made that a
little bit different just to make it
easier to see
notice that
we have profile grips we can adjust the
pvi we can also adjust the the gradient
and the grade out so it makes it very
easy to edit
also notice it is setting that five and
a half foot cover depth at each of the
bend locations so it's a little closer
to the ground here a little farther away
here since we're dealing with an
existing surface you can see it's just
measuring right there and then it's a
straight shot to the bend here if we
wanted this to better follow the ground
since my pipe run is selected I'm going
to go back to pressure Network land view
here and I'll choose piperun profile and
let's flip this to cut length and I'm
not drawing a new one I'm just going to
say update the one that we have
when I click OK you can see how that
updates now the styles that I'm using
for my pipes are displaying the end
lines so it's showing me the cut lengths
that are defined from the parts list and
now it's measuring that five and a half
feet at every cut length it's deflecting
the pipe at each of those cut lengths
let me drag this over
if I select this basically I have more
pvi grips historically we used to have
multiple pvi grips along the individual
pipes which made it cumbersome to edit
these vertically now since we have a
nice pvi grip at each cut length I can
make they're easy edits to this as an
example I'll click the grip here I can
pull this down I can click the grip here
pull this down
and I'll press Escape let's zoom out a
little bit
and let's look at what we really did by
adjusting those grips if I select the
pipe rotten you're in profile and go to
piperun profile
basically I've said I want it to follow
this surface okay five and a half feet
below and I'd like it measured at the
cut lengths notice there's an overrides
tab here
and there's a single override if I
select that you can see overrides this
is where I've gone through and manually
adjusted things so from now on if this
surface was to change the pipe Network
would update in this area but it will
hold the adjustments that I've made or
the overrides I've made in this area
and we can delete overrides if we want I
can select that click the delete button
click OK you can see that I'll go right
back the way it was
the reason I show you that is because
this can be used to create lowerings
real quick here I'm going to simulate
uh pipe Crossing or utility Crossing
we'll say that's maybe a sanitary sewer
or something like that that we have to
deviate around
if I select my pipe run
I can very easily click these grips
and I can pull this down
and you can create a geometry here with
the appropriate slopes and the
appropriate maybe it's 18 inch
difference here I'll leave that up to
you just want to show you that very
easily I can grip edit these I can use
the grips here to
hold the grade coming in going out to
create a lowering and I just applied it
and basically I applied an override
when you make adjustments like this the
pipe is deflecting at each of these
locations if you wanted to place a
fitting at those locations
let me select this and from the
contextual ribbon I will choose add Bend
pvi
and I'll say I want to add a actual Bend
to the profile which will
which we'll put
the appropriate elbow
or the appropriate fitting at that
location
there we go let me press Escape
and if I zoom out
let's come over here
I will click once I will click a second
time
we'll window these and then I'll right
click and choose object viewer
and we'll just pull these up in 3D
so you can see there's the lowering with
the fittings
let's pan this back over
so very easy to create lowerings now we
do that as an override let's dial things
up just a little bit more
I'm going to launch the copy command
and we'll copy this
maybe we'll come down here and we'll put
one here and maybe we'll put one here
let's say I need to deviate around these
two maybe these are crossing elements
sanitary sewer storms or something like
that
I can create my lowerings as a profile
if I select
the profile view and go to profile
creation tools I can create a civil 3D
profile for this I can call it lowering
a
and I don't need labels on this
I can then draw this
maybe we'll start nearest to here so
we're not doing it right at one of the
cut lengths and I could use the
transparent tools if I wanted to draw
this at a particular slope or grade draw
it to a particular elevation once again
I'm going to leave that up to you
just showing you that you can create
your geometry
for your lowering
we'll take this up to maybe nearest to
here
perfect let's close this now if I select
my pipe run if I go to the piperon
profile
and go to overrides I can create a new
override
starting station
will be the end point here
end station
will be the end point
here
and in this area I would like to follow
the lowering a
profile that I created I would also like
the distance below that
I almost always forget this you can see
if that's five and a half feet down it's
going to try and draw this five and a
half feet below my profile since I want
that profile to represent the top of the
pipe I'll set my distance to zero I will
then choose cleanup pvis and I'll click
ok
and you can see how that pulls it down
now I can if if I'm going to add
fittings I can do this let me choose
we'll select this and I'll do add Bend
pvi
since we did it in the middle of a pipe
I can say I want to add a Bend right
there there's my fitting
I want to apply a Bend right there
there's my fitting
and I could put other ones on here or I
could have used the grips and I could
have pulled those over if I just wanted
to show these as deflections as opposed
to having an actual fitting there okay I
don't know if I touched on this just
want to make sure if I select the pipe
running profile and get access to the
profile object select it a second time
now I have access to the individual
components okay works the same way let
me go ahead and close this
all right dangerously close to the end
of the session here let me bring this
back today we looked at how we could get
started modeling pressure networks in
civil 3D we looked some of the new
functionality some of the things that
have been added since 2021. we talked
about how we could create a parts list
or a subset of the overall catalogs that
come with civil 3D that parts list
represents the tools that we use most
often when we're generating pressure
Network designs parts list is stored in
the templates for easy use with all the
drawings that we create
we also talked about how we could
generate pipe runs the pipe runs
represent branches in the overall water
Network we can have more than one run
within a network
we can connect Those runs together and
the runs are based on an underlying
alignment and profile which makes it
very easy to edit the geometry and the
fittings both horizontally and
vertically if you get a chance to use
this feature don't assume it has to be
used for just pressure networks several
types of utilities that you may want to
model are based on depth of cover things
like gas main or Fiber Optic line you
could kind of hijack this feature to
model some of those items as well
when it comes to the additional
resources I just want to share with you
a couple things I will have the links
for these in the description for this
video I've got a link here to the
Autodesk University online site
if you go here you can access Autodesk
University
classes from prior years not just 2022
but it goes back several years there's a
search feature right here you can do a
search for pressure Network we can do
searches for other topics or other
workflows with respect to civil 3D or
any other Autodesk application there's a
wealth of information available here
and in the Autodesk University online
site one of the recommendations I would
make is to take a look at this class
that was done in 2021 by Charlie Ogden
I'll select the hyperlink
this was found just using the search
feature in 2021 with the new pipe runs
Charlie gave a presentation on this you
can watch the video right there he also
includes the presentation and the
handout I show you this because Charlie
walks through some additional ways that
you can edit your part catalogs and he
also includes links to other resources
that will give you even more information
if you'd like to make hardcore edits to
those catalogs
civil immersion blog
myself and a couple other technical
Specialists have put together this blog
and over the last several years we have
posted hundreds of how-to workflows for
many of the Civil infrastructure
applications in the AC collection once
again another wealth of information if
you visit the blog you can see that each
of us has a dedicated YouTube link there
as well where you'll find all of the
videos that each of us have created
and I show you that to show you this
I will provide the hyperlink here Alan
Gilbert gave a wonderful presentation a
few months ago that walks through
getting started using pipe runs and
pressure networks and Alan also walked
through the process of assigning pay
items within your pipe Brunson and doing
the extractions so this
link will also be in the description if
you'd like to explore that topic
okay at this point we can address any
questions that you may have
