AutoCAD® MEP 2012 and Autodesk® Navisworks® Manage Tips and Tricks for the Daily User
Create and support a productive Template:
What does it take to sit at your workstation and do your work in an efficient and productive manner? As
with any job, it is the tools that you use to make things it easier and more user friendly. A really smart,
well thought out template is the best way to start productivity. There is a huge amount of setup and info
that a template can hold.
Let’s look at what we can setup in your template:
1.
2.
3.
4.
5.
Piping System Definitions and Routing Preferences.
Dimension and Text styles and Units settings.
Preset Layers and Line-types settings, plot-styles and layouts.
Style manager settings, label curve and schedules.
Catalogs and Workspace settings.
While I don’t want to make this a class on “CUIX” or custom lisp routines, these are both good tools to
have knowledge of. Learning how to tweak and change the settings is really helpful. I will get into a few
good setup items that will make designing easier. The style manager is the easiest and most powerful
way to customize without making CUIX changes directly.
You’re AutoCAD Profile:
This is the basis of all of your customized setting. You can have multiple profiles, but the more you have
the more confusing it gets. I would suggest using one profile and multiple workspaces. Once you get all
your customization complete (that’s funny) you can save your profile. You can get to the profile by typing
“options” at the command line or right mouse click on the command line and selecting options. You can
start a new profile or simply modify an existing one, but either way the best thing to do is to take charge
of AutoCAD and make the program do what you want to.
2
Style Manager:
This is probably one of my favorite places to customize for piping. There are a ton of settings and set-up
you can do to be more productive inside of the style manager. Let’s take a look at the basics parts of the
style manager and break down the general areas we will cover. You can find the style manager on the
manage tab of the ribbon.
This is where the automatic annotation
for piping callouts comes from.
This is the place all the general info for
schedule, tags and labels are stored.
This is the default location for all of your
schedule table templates.
This is a real power house for
customizing piping systems. It is really a
layer manager for the piping systems.
This is the place we will be doing a lot of
setup and customization along with the
system definitions. This is a key part of
making things easier when piping is
properly setup in routing.
This is the location for all of your piping
systems. This is where you can preset
all of the piping systems you will design
with.
3
Dimension and Text styles and Units settings:
You should have all of these options setup in your template so they are always available for use without
having to go back and change your setup.
Preset Layers and Line-types settings, plot-styles and layouts:
All of your layer and line-type settings should be included in your template. An example would be an
“xref” layer that is locked so you could take advantage of the layer lock fade control settings. You can
have your xref be faded now in the background and locked for safety of keeping it in place. Another
good preset is a pipe insulation layer. Having a preset insulation layer in your template will allow you to
force piping insulation to its own manageable layer through the display manager. But the layer must be
in the template first to be able to utilize it.
Piping System Definitions and Routing Preferences:
This is the most important part of a good piping system. It is without a doubt the heart and soul of all
your systems. Again we will look at this deeper in later segments.
Catalogs and Workspace settings:
This is the second most important part of a good piping system. It is where you will do presets for piping
and choose how and what you see in any given workspace.
Draw and Modify Slope Waste piping in AutoCAD MEP:
When trying and I stress a lot of “trying” to master sloped piping in MEP, I have discovered the one really
important thing to have is Patience. In trying to design and detail piping in MEP I have found that you
can always expect is the unexpected. What I mean by this is that the “sticky move” is not always your
friend and in AutoCAD MEP trying to be helpful sometimes it hurts more than helps. Trying to just drag a
simple 90 degree bend can be a huge pain.
Trying to add a simple 90 deg. bend to this island vent waste system can cause problems. Just grabbing
the add grip on the pipe and adding a fitting can “move” other fittings around into unwanted spots. As you
can see, MEP has “adjusted” the location of the combination and san-tee in the snapshots above. In the
last snapshot, one simple break of the branch pipe can stop this from happening. While you cannot easily
add the pipes together, I find it better to just delete both ends of pipe and let it auto-fill between the
fittings by the pipe add grip to re-populate the pipe in between them.
4
Sloped piping is a challenge to say the least and more like an art-form. There are many designers that
struggle with sloped piping systems because you can really get messed up quickly trying to drag things
around as you would flat piping systems. What would be really good is a pin command in AutoCAD that
would let you “pin” down a main line of the system so it cannot move on you (wish list item for sure).
Some of the key settings for slope piping are:
Piping System Definitions: This is the
piping system you are designing with.
This is controlled by layer key styles.
Examples would be DCW, DHW,
VENT, SS systems
Routing Preferences: This is what will
decide what type of fittings; pipe and
joints are used while drawing piping
systems. Examples would be Cast
Iron, Copper Pro-Press, Copper
Brazed, Threaded Steel, Butt-Welded
steel, etc.
This is the starting elevation of the
piping system you are about to draw
This is where you set the slope of your
piping system. (1/48 is ¼” per foot of
slope getting shallower as you draw,
-1/48 would be ¼” per foot getting
deeper as you draw the piping. This
setting can be fractional or angle
(decimal) format. IE: 1/48 is equal to
2% slope angle.
Label styles are what annotate the
pipe as you draw it or when you need
it to annotate on demand.
TIP:
One thing that is critical to you while drawing in
MEP is to always have your solution tips ON and
showing during your piping session. This is the
only way to know you are both accurate and the
schedule and material lists are correct.
Image 1: Solution tips On, System is connected.
Image 2: Solution tips Off, Riser moved up 2”.
Image 3: Solution tips On, 2” gap revealed.

Lets look at some of the problems that might arise
from the screenshots above:
•
•
•
•
If you decided to stretch the main line using
grip editing the riser would remain in place.
MEP part numbering would have a problem
with this disconnect.
The gap would be 1” short of pipe in a bill of
materials (BOM) schedule.
If you changed an elevation of the main line the
riser pipe would remain unchanged.
In drawing pipe and fittings there are editing
commands in the “MEP” world that work better than
the standard AutoCAD commands. A good example
would be using the pipe edit grips to slide a branch line
12” to the left rather using the stretch command.
TIP: Primarily as a rule, It is always better when drawing piping systems to use the
MEP osnap’s instead of the generic AutoCAD osnap’s. Leave the generic osnap’s turned off, if you need
to use them use your shift + right mouse button will bring up all the osnap overrides.
There are four views shown below of some pipe and a combination fitting. The pipe is sloped at ¼” per
foot fall as well as the fitting. What if you wanted to roll the “comby” on a 45° angle. There is a far better
way to do this than the standard “rotate3d” command, the MEP grips will let you easily change direction
of the fitting and flip from side to side. How to roll the fitting 45° it is the question and desired angle. As
long as the fitting does not have a coupling or pipe branch attached you will see a diamond rotate grip
when you select the fitting. If you have your dynamic input (F6) on you will get an option to roll the fitting
to any input angle. There are two forms of input, absolute and relative and use the tab key you can cycle
thru them.

Create Bill of Materials and Cut sheets for
fabrication:
It is possible in AutoCAD MEP to design in 3d to
create a BOM with a full material list ready for prefab,
in these screenshots I have drawn a small waste
system, using the MEP part numbering tools and a
schedule with a few specific property sets attached to
it. We can also add part numbers to it and create a
spool or prefab drawing for fabrication and installation.
This is a fairly easy thing to do, with a few tweaks to
the schedule and some creative use-age of tags and
blocks. Let’s take a look at this process.
This is a step by step method to get a bill of materials
and a cut sheet with part numbering as well.
1. Create the desired system to be scheduled.
Remember that if you select too much at a time
the drawing will get busy fast. It is best to break
systems up into smaller spools.
2. On the Annotate Ribbon go to the
scheduling/tags panel and select the pull-down
menu, choose the text part numbering tag. This
will bring up the numbering dialog box. Check
the radio button for individual objects and pick
the select objects button. This will put you into a
selection mode, you can just window all of the
pipe and fittings and hit the enter key. When
the dialog box comes back choose “ok”. This
will start the auto numbering of all pipe and
fittings. When finished with the numbering
choose one of the numbers and the leader and
right mouse click choose “select similar”. This
will highlight all the numbering you just inserted.
Then hit the delete key or “e” end enter, deleting
all the numbers you just added to the drawing (I
know this sounds funny, but let me explain). We do not
need these numbers as we will be numbering later in
paper space through the viewport. We only need the
property set involved from the part numbering routine.
Once the numbering routine is run and all parts have a
part numbering property set associated with them.
7
3. We will now add a generic
schedule to the drawing in
model space. Go to the
Annotate ribbon and the
scheduling/schedules panel and
select the pull-down menu. For
this I will choose the pipe
quantity schedule to use since it
is a small schedule with little to
get info rid of. We will be adding
our own column and info
preferences to the schedule
thru property sets available to
us. Select the schedule and right
mouse click on it. In the dialog box
choose the “edit schedule table style”.
This takes us to the dialog box for
editing the schedule. You can add and
delete and columns in your schedule.
We will add two more columns in this
schedule shown here to get a couple
more columns we
need. One of them is a
pipe object property
column and the other
is a formula column for
sorting. It wasn’t really
fair for the fab shop to
have to sort through a
pipe than a fitting all
mixed together, so I
wanted the pipe to sort first, small pipe size to large and
then by fitting type. I don’t need these columns for any but
the sort order of the columns, so I will hide the columns by
selecting the hide check box when I am inserting the
formula. Once we get the schedule in order all there is to
add is the part numbering in the paper space view. This is
done using a standard part number tag. Without getting too
involved in the setup, I am providing a screenshot of the tag
I am using for the part numbering. The real beauty of using
this tag is that you can use this tag for the pipe and fittings
through paper space right in your page layout. This will
allow you to place all the part numbers in a logical order
instead of just dumping all the tags into a huge clump in the
middle of the sheet. It may take a few minutes longer but it
comes out much cleaner this way

Create or add piping systems and routing definitions easily:
When you are doing pipe routing in MEP the entire piping system is basically relying on three things;
System definitions, Layer keys and routing preferences.
In the next section we will add a new system definition and a routing preference in the style manager
and explain the how-to’s of these two settings.
System Definitions:
Go to the style manager on the manage tab and select the arrow under the style
manager. This is the pull-down for the two settings we are going to be doing the
system editing in. Select the piping system definitions and a dialog box will come
up in the piping systems area of the style manager. In this section on the left pane
we will right mouse click on the standard piping system and copy and paste a new
system into the piping systems. In the right pane we will add the abbreviation of
“SS” and in the layer field we will add a discipline designator for PL and a minor 1
for the “SS” field as well. We will also tell the system to use the layer key shown for
layer name, color and line-type. This will do a few things, first when the pipe is annotated it will read
both the size and the “SS” for the system callout on the plan view and also as you draw piping on this
system it will automatically create it on a PL-SANR layer. In the routing preference we will do the same
copy of the standard routing and edit for our use. We will now open the layer keys in the style manager.
Layer Keys:
This is a screen shot of the layer keys in the style manager. The Layer keys are sort of like the layer
manager for MEP objects pipe and fittings, and it is used for controlling the way piping looks, its
annotation, color and layer name. We need to add the layer info for this system into the layer keys.
9
Routing Preferences:
We will now create a waste piping routing definition. When the routing dialog box is open you have to
select the default pipe and fittings to be used by this routing preference for each system drawn. Start out
in the same way as the system definition and copy the standard routing pref. and rename it to Sanitary
Waste. The screen shot below shows the fittings I have chosen from the menu pull-down for each type
of part in my waste system. For each of the parts needed we are able to select the desired fitting
wanted. This also includes what type of pipe you will use. Once we get the routing system defined we
will copy /paste it and change a few fittings to be used for the vent system. The only changes I will make
for the vent system is the no-hub combination and the short sweep will be exchanged for a san tee and
a quarter bend. Using the “pipeadd” command we will draw some waste piping with the new system
definition and routing preferences. You can see by the screen shots that I have selected the system and
routing pref., pipe size, elevation and slope prior to drawing any piping in the properties dialog box. And
the overlay image is the properties palette of the pipe I just created.
Looking at the properties of the piping, you can see how the system definition, layer keys and routing
preferences all come together. You can also see that the system definition and routing preferences
worked on the new piping and that we did get the correct fittings for our system.
Modify layer keys & label curves make pipe annotate automatically to your specifications:
When I first started in MEP I was not satisfied with the standard auto annotation of the piping. It didn’t
give the info I needed or proper layer settings. I needed to fix that, so I dove into the label curves and
had a go at it. Let’s look at how a label curve works. What it is doing is grabbing property set definitions
from the pipe object you select and the layer override from the system definition we added. Remember
the “SS” we added in the system definition? That is what it was for. Look at the style manager for the
documentation/label curve styles. Do the same things as before and copy/paste the standard label curve
10
and we will rename it to “PIPE-SIZE-ANNO”. There are not too many settings we need to adjust in the
label curve style; just a few tweaks and we are ready to annotate some piping.
Use object props.
and abbr. settings.
This is where the
size will come
The text style
for the new
label curve
This will mask
smaller pipe
sizes around
the label
This is the new
label curve we
just created.
This tells the
label to use
the layer
overrides we
made.
This is what I get now if I add the new label curve to a piece of pipe.
If you notice that the layer matches the system and each time you
draw piping on a new system and annotate it, the anno layer for that
system will automatically be created. This helps when trying to
isolate a system or only plot certain systems to a plan sheet. It is
very important to create
Create and modify palette content to maintain standardization in piping design:
In trying to make it as easy as possible for a user to design a piping system in MEP, it seems pretty easy
to just draw piping from the standard piping palette. But, there were a lot variables in doing this for the
user to decide on and in some cases use incorrectly. Some of the questions that came up were; what
routing preference and system definition do I use? What elevation do I use? What layer name should I
use? What color should the piping be? We are constantly trying to standardize things to make life easier
and all these questions left too many open ends for people to tweak and change. What I think a layer will
be called likely will not be the same as what you would call it. Maybe I like cyan pipe for cold water and
you like blue. This was a huge concern when you have 15 engineers and 25 detailers all trying to play in
the same sandbox together. While this is not a huge problem, it would always come back and haunt me
later when someone would say that their drawings were not plotting correctly and always under crucial
deadlines. In diving into the root of the problem, most of these were from color and layer overrides or not
following company standards since we use a .ctb to plot drawings. The common task and goal here is to
take a model from the design/engineering phase of the project and use the same model all the way
through fabrication. Sounds easy enough, right?
Presets are a key to the setup we use for our company. Although some of the presets are just
temporary, most of the project in the engineering phase are “schematic and the elevations are not the
most important factor. Just getting the engineers to commit to 3D was a huge task. By creating presets
11
on a palette and showing them the ease of changing pipe sizes on the fly and auto annotation of pipe,
we were able to make the smooth change to design conceptually in 3D in the engineering department.
Let’s look at the piping palettes side by side. Out of the box MEP gives a preset in many different
methods of creating pipe systems. Our palette adds more control over the company standards and
though the piping systems had preset properties already, MEP lets you change them on the fly when
needed. What I did was to add control for a specific piping system variables though the palette for our
piping systems. When a user wants to draw waste pipe horizontally, they can choose the icon from the
customized palette and all they have to do is select a pipe size from the palette and edit the elevation if
needed and they are drawing to the company standards with little thought about setup at all. In our
company standard shortcuts for the “pipeadd” command we have set up all the backend settings for
each system to make it really easy to just think about piping and let the program presets manage the
standard settings for you. On the standard MEP palette you get a couple of different choices in different
categories, but in ours you can see all the variables are preset for the user ahead of time. We can preset
all of the following for the user ahead of time; layer keys, system definitions, routing preferences, pipe
size, elevation, slope angle (if needed), and even the pipe label curve style. Now this is productive and
easy to start designing a piping system.
12
Create and implement a standard Navis Manage Profile for Daily Use and coordination:
In using Navis Manage on a daily basis there was a lot learning and training to do and plenty of lessons
learned in the process. Once Navis manage is in place, coordination and collision detection are started
on a project, the demand for Navis is pretty much non-stop. At our company we practically live and
breathe Navis now. One thing is for sure Navis Manage works smoother with consistency. There must
be standardization and consistency to maintain a steady workflow. There is nothing more frustrating
than to work the entire day sorting out collisions in a model and have someone lose all the work by
overwriting your clash report. We needed to implement a standard template for the users and enforce it
to get a steady flow and most importantly productivity.
A really helpful thing to have in the Navis model your use is some form of 3D grid in the model. It is
really important when you are in the coordination process that the users know exactly where they are at
in the model without having to zoom in and out all of the time to find out their bearings and grid
locations. We have found it best to have a 3D grid about 1’-0” above the floor and about the same above
the highest steel in the model.
Here are a couple of grid samples we have seen in our coordination models:

There are many ways to select objects in Navis Manage and
one of the best ways we have found is to use selection sets to
group objects. This is done by selecting a group of objects
and choosing the save selection panel on the home tab
ribbon. The items can be selected either using a pick off method or through the selection tree at a file or
object level. It really does not matter how the objects are selected, once you get them all selected you
can make a selection set and call up that group of objects at any time you need them. This is how we
are now doing our collision coordination. It is fast and very simple to get a bunch of objects together and
it also is searchable for use if needed.
Another really good tip when trying to create selection sets in Navis Manage is to utilize the shift key
while you are selecting an object. This will aide in your selection of similar objects in a scene. As you
select an object holding down the shift key, it will cycle thru that object as a single object. As you keep
selecting the same object holding the shift key down it cycles through all objects that alike. Navis will
cycle you through the objects at different hierarchy levels per pick. Object level, entire scene level, file or
drawing level, system or object type, then back to object again. This is really helpful if you are trying to
selection all of the walls that are similar, or all duct in a scene for a selection set. Once you have
selected the desired objects you can on the home tab/ save selection panel to create a selection set of
the items.
A helpful tool we use in our models is transparency overrides in the model. This helps us to see objects
like framing and structural objects without being blocked from seeing the piping and ductwork we are
trying to manage. You can make any object in Manage transparent by right mouse clicking on the object
and choosing the override item/ override transparency option to bring up the slider for making items see
through. This can be done also anywhere and at any level of the selection tree. Just as you can change
the transparency of objects in Navis, you can also change the color of objects and coordinate trades as I
show below. This easily helps others in coordination know what discipline you are trying to focus on.
This is really helpful in a crowded model with all trades brought in.
NWNAVIGATOR is another user friendly feature of Navis Manage that has become indispensible to us.
It gives the user the ability to use a Navis like interface right inside of AutoCAD. At the command prompt
if you type nwnavigator, this will bring up the window in AutoCAD that will let you visually see your model
just as you would in Navis manage.
A really helpful tool they have added into manage is the batch utility for making Navis files automatically
for coordination. We spend hours at a time in coordination meeting and have to rely on always having
the latest and most current files at the time of the meeting. By using the batch utility and using the
windows task scheduler we are making files on our projects in the evening automatically, so when the
detailers come in to work or we go to a coordination meeting the files are as current as possible. We
have batch routines in places that copy dwg files into a specified folder, the batch utility opens the file in
Navis and creates the NWC/NWD file automatically for use in the morning.
Navis Settings
Global Options Setting
Display unit: set to Inches. This will read as decimal inches. Fractions do not work with negative
fractions less than an inch. Snap setting: turn on for vertex, edge and line vertex. File reader settings:
Convert xref’s and merge xref layers turned off.
14
File option setting
Backface culling should be set to off. This will stop the objects from disappearing as you get really close
or inside of it.
Clash Detective Set-up
During the Coordination phase, Navis Clash Detective should be run with following Set-ups:
(This is the typical setup for our company and you can adjust accordingly for yourself.)
•
Batch Tab
The Batch tab
enables you to
manage your clash
tests and results. It
shows the entire
clash tests currently
set up, listed in a
table format. You
can use the scroll
bars at the right and
at the bottom of the
tab to move through
the clash tests.
Naming and Color conventions will better aide in the coordination process.
Trade identification might be as follows:
MH = Mech. HVAC Duct
MP = Mech. Pipe
PL = Plumbing
FP = Fire Protection
EL = Electrical/Lighting
PT = Pneumatic Tube
AW = Architectural Wall/Studs
RC = Reflected Ceiling
ST = Structural Steel/Concrete
SS = Supplemental Steel
o The Rules tab enables you to define and customize ignore rules to be applied to clash
tests. It lists all currently available rules. These can be used to make Clash Detective
ignore certain model geometry during a clash test. Each of the default rules can be
edited and new rules may be added as necessary.
o The following Clash Rules will be checked that will ignore clashes if:
Items in same layer: any items found clashing that are in the same layer are not
reported in the results.
15
Items in same group/block/cell: any items found clashing that are in the same
group (or inserted block) are not reported in the results.
Items in same file: any items found clashing that are in the same file (either
externally referenced or appended) are not reported in the results.
Items in same composite object: any items found clashing that are part of the
same composite object (an item composed of multiple parts of geometry) are not
reported in the results.
Items in previously found pair of composite objects: any items found clashing
that are part of composite objects (items composed of multiple parts of geometry)
that have previously been reported in the test are not reported in the results.
A Batch Test could be set-up for all
jobs with the following batch files
Trade (XX) vs. AW: batch for each
trade vs. 3D walls and stud as
provided per job.
• Architectural model to have
studs and top track on
separate layer to be able to
isolate the top track to
eliminate all false collision for
vertical pipe penetrations.
• If possible, top and bottom
track to be modeled showing
two edge pieces and no back
(part that attaches to deck) to
eliminate false clashes for
penetration, but identify
sleeves/pipes that are out of
wall.
Trade(XX) vs. ST: Batch for each trade vs. structural steel, supplemental steel or slab or
footings
Trade (XX) vs. RC: Batch for each trade vs. reflected ceiling plan if available or a separate
file.
MEP vs. MEP: All trades vs. each other in one batch for internal and external coordination
tracking.
