PHC LC KHC PHC MT S LI TRONG CIVIL 1. Subassembly Names Disappear on Copy, Move or Mirror
Do your Subassembly names disappear whenever you use the subassembly commands
Copy to, Move to, or Mirror?
After the jump learn how to resolve this issue.
The issue lies with the subassembly naming template. I dont know if others out there in
blog land knew this but using is no good.

The same name is provided but now when you copy, move, or mirror the names dont
disappear.

2. Magic Corridor Boundary So you have a corridor surface which needs a boundary. Youre used to using Civil 3D
2009 and you know about the Automatic boundary, say, from the daylight lines.
You also know that the Automatic boundary doesnt always happen depending on certain
conditions. So you installed Civil 3D 2010 because you heard about this new fantastic
boundary method known as Corridor extents as outer boundary. You opened your
corridor properties only to discover that the option isnt where its supposed to be. Follow
the jump to find it.
This option only exists when your corridor has multiple baselines. CRUD! Enter the
workaround.
Just add another baseline to your corridor. Thats it. Dont add any regions to it, just an
empty baseline. Go back to your boundaries tab and voila, you can add the extents
boundary.

3. Civil 3D Part Builder Not JUST 3D Part 2 Creating a Custom Variable
Based on some of the comments from the previous post, I am going to take a couple of steps
ahead and cover creating a custom variable that can be passed to the Parts List in Civil 3D.
This post is assuming you already understand the basics of Part Builder and know how to
model a structure. If not dont worry, we will be getting back to the basics in Part 3.
Step One (Note: it is very important that these steps be followed in exact order), click the
options button at the top of the Content Builder as shown.
In the Options dialog box check the Custom Sizing Flag and click OK. What this does is
allow the ability for us to create a custom variable and then later adjust that variable in the
xml files that will allow the custom variable to be visible in the Part List. This is an
-
Chuyn thit k ng trong Civil 3D
BQT din n www.kythuatdothi.com Trang 44
important step, because we can still create the custom variable in Part Builder, but if this
option is not checked then certain information for that variable will never come through
after editing the xml files and then never be available in the Parts List.
Step Two, create the initial variable. In the Content Builder go to Model Parameters right
click and select Edit.
In the Model Parameters click New and you will get the following dialog box.
In this example I am creating a parameter that I will use for an inline reducer structure I
created. I am already using SID, the Inner Structure Diameter for the diameter coming
-
Chuyn thit k ng trong Civil 3D
BQT din n www.kythuatdothi.com Trang 45
into the structure. So I need another parameter for the reducing diameter coming out of
the structure so that I will be able to create multiple part sizes in Parts List from a single
structure. Make sure you keep in mind or write down the exact name and description of
the new parameter just created, because we will need to add that exactly as it is here in one
of the xml files. For now just use a constant value for the Equation because we will modify
this in the Size Parameters.
Step three, modify the size parameters. Right click on Size Parameters, as show below, and
select Edit Configuration.
In the Parameter Configuration dialog box, shown below, find your new variable. We will
want to modify this variable here as much as we can to be what we want so there will be
less to do in the xml files
In my variable RID, the Reducing Inner Diameter, I have changed the Data Storage type
from a constant to a List, that way I can go into the values for this variable and add all the
sizes that I will use to create this part in Parts List. We also want to change the Visible
attribute from False to True; this is part of what will allow us to see this variable in the
-
Chuyn thit k ng trong Civil 3D
BQT din n www.kythuatdothi.com Trang 46
Parts List when adding sizes. Now look at the Context and Index Attributes for this
variable, shown above in the box, these are the pieces of information that we will need to
modify in the xml files that will allow the variable to pass to the Parts List. Youll notice
that in the context of this variable that it is calling it a Model Distance Parameter, where
the other variables have a specific context matching the variable itself. This is because the
context for this variable does not exist in the xml file, so we are going to have to add it. Also
you will notice the Index of this variable is set to 1, were the others that pass to the Parts
List are 0, we will have to modify this as well in the xml file.
Step four, edit the xml files. Make sure you save your structure and exit Part Builder, and
close Civil 3D before we edit the xml files. Once everything is saved and closed there are
two xml files we need to edit. The first will be the xml file for the structure itself which will
be located in /Pipes Catalog/US Imperial Structures/Your Chapter/Reducer.xml, where
is the location on your system for the Pipes Catalog and Your Chapter is the chapter
you created at the time you created or saved the initial structure. The second xml file to
edit will be /Pipes Catalog/Aecc Shared Content/AeccPartParamCfg.xml, this is the xml
file that will read the context of the structure and eventually allow us to pass this variable
to the Parts List.
Open the structure xml file with notepad.
Find your new variable as shown highlighted above. Then find the context and index for
this variable also shown highlighted above. Change the context to be something similar to
the description with no spaces, for this variable I used StructReduceDiameter. Then
change the index to 0. Remember to keep the parenthesis on these attributes. Save and
close the xml file.
-
Chuyn thit k ng trong Civil 3D
BQT din n www.kythuatdothi.com Trang 47
Now open the AeccPartParamCfg.xml file.
In this xml file the new variable does not exist, so we have to create it in two places. In this
case the easiest thing to do is find a variable that is similar to the one you created; the RID
variable is similar to the SID variable. Do a search for SID copy the line and paste into a
new line as shown highlighted above. Edit the variable name, description and context to
match what is in the structure xml file.
Now we need to add the context to the Structure Domain.
-
Chuyn thit k ng trong Civil 3D
BQT din n www.kythuatdothi.com Trang 48
Find the Structure Domain towards the bottom of the xml file or do a search for the
context of the variable that is similar to the one you created. It is very important in this
step to make sure we add the context of the new variable in the appropriate Domain type.
In the case of the inline reducer, I created it as a Junction Structure, so I added the context
of StructReduceDiameter in the Junction Structure category, as highlighted above. Save
and close the xml file.
The final step is to verify that everything works. Reopen your structure in Part Builder and
go to the Size Parameters, Edit Configuration.
-
Chuyn thit k ng trong Civil 3D
BQT din n www.kythuatdothi.com Trang 49
ou will see by the highlighted information above that the Context and Index of the variable
is now reading the information that we edited in the xml files. Exit Part Builder and go to
your Parts List in Civil 3D add the Part Family for the structure if not already in your list
and go to Add Part Size.
You will see by the highlighted information that our custom variable is now available in
Parts List.

4. Modifying Cover and Slope Rule H
ave you ever started laying out a pipe network using the cover and slope pipe rule or Pipe Cover
and found the pipes down near the zero elevation? Well if your like me you dont really
appreciate having the pipes down at the zero elevation. Heres a way to change the rule to put the
elevation at a place which would be more desirable without having to move the pipes later on.
NOTE: Before you start make sure you save a copy of the C3DPipeRules.dvb to another location
to easily go back to the original state.
To do this open up the Visual Basic Editor after you have worked with a pipe (working with a
pipe should load the C3DPipeRules.dvb file automatically). This post has more information on
how to load Visual Basic files. Go to the CoverAndSlope Module and scroll down to the Public
Sub ApplyWithoutSurface routine, to the part that is below:
1 If the last elevation is equal to our double max,
2 then the last elevation has not been set in the network state
3 and we will set the starting elevation to the minimum cover
4
5 If dLastElevation = c_DBL_MAX Then
6 dNewPipeZ = 0
7 If eFlowDir = aeccPipeFlowDirectionStartToEnd Then
8 dNewPipeZ = dNewPipeZ dMinimumCover
9 oPipe.StartPoint.Z = (dNewPipeZ oPipe.OuterDiameterOrWidth * 0.5)
10
11 ElseIf eFlowDir = aeccPipeFlowDirectionEndToStart Then
12 dNewPipeZ = dNewPipeZ dMinimumCover
13 oPipe.EndPoint.Z = (dNewPipeZ oPipe.OuterDiameterOrWidth * 0.5)
14 End If
15 otherwise set the starting elevation to the last elevation
16
17 Else
18
19 If eFlowDir = aeccPipeFlowDirectionStartToEnd Then
20 oPipe.StartPoint.Z = dLastElevation
21 ElseIf eFlowDir = aeccPipeFlowDirectionEndToStart Then
22 oPipe.EndPoint.Z = dLastElevation
23 End If
24 End If
You can change the dNewPipeZ = 0 (Line 5), to a new value or we can change it to prompt the
user for the elevation they want to use. The new line could be the following:
dNewPipeZ = ThisDrawing.Utility.GetReal(vbCrLf & Surface not found, enter invert elevation
to use:)
If you then create a pipe network you will see that we have two problems with the change of
prompting the user for the invert elevation. The first is the invert elevation of the first pipe is not
the same as the one we entered into the program and the second is that it asks you again to enter
the invert elevation at the end of laying out the network.
-
Chuyn thit k ng trong Civil 3D
BQT din n www.kythuatdothi.com Trang 51
The first problem is explained in the code shown above, it is setting the starting elevation to the
minimum cover as told in the programming notes. To correct this remove lines 8 and 13 from the
code above and change the negative sign and the word outer in lines 9 & 14 to a positive and
Inner. I suggest using a before the line to remove it and adding a note to explain why you did
the change so you can easily go back at a future date and reverse the revision. The
oPipe.Endpoint.Z and oPipe.StartPoint.Z refer to the center of the pipe.
The next change we have to make is to get the program to not ask you what the invert elevation
is the second time. To accomplish this we are going to add an If Then statement around where it
is setting the starting elevation. So right after line 5 add:
If oPipe.StartPoint.Z = 0 Then
After line 16 put End If. So the finished code should look something like this:
1: If the last elevation is equal to our double max,
2: then the last elevation has not been set in the network state
3: and we will set the starting elevation to the minimum cover
4: This portion was revised to allow the user to input the starting elevation instead of
5: setting the starting elevation to the minimum cover.
6:
7: If dLastElevation = c_DBL_MAX Then
8: To get the program to not ask us for the elevation again we will check to see if the start point
z is zero
9: If oPipe.StartPoint.Z = 0 Then
10: dNewPipeZ = ThisDrawing.Utility.GetReal(vbCrLf & Surface not found, enter invert
elevation to use:)
11:
12: If eFlowDir = aeccPipeFlowDirectionStartToEnd Then
13: Line below removed to allow the user to provide the invert elevation.
14: dNewPipeZ = dNewPipeZ + dMinimumCover
15: The + was a negative sign and Inner was Outer to get invert of the pipe instead of the top
of pipe.
16: oPipe.StartPoint.Z = (dNewPipeZ + oPipe.InnerDiameterOrWidth * 0.5)
-

17:
18: ElseIf eFlowDir = aeccPipeFlowDirectionEndToStart Then
19: Line below removed to allow the user to provide the invert elevation.
20: dNewPipeZ = dNewPipeZ + dMinimumCover
21: The + was a negative sign and Inner was Outer to get invert of the pipe instead of the top
of pipe.
22: oPipe.EndPoint.Z = (dNewPipeZ + oPipe.InnerDiameterOrWidth * 0.5)
23:
24: End If
25: End If
26:
27:
28: otherwise set the starting elevation to the last elevation
29:
30: Else
31:
32: If eFlowDir = aeccPipeFlowDirectionStartToEnd Then
33: oPipe.StartPoint.Z = dLastElevation
34: ElseIf eFlowDir = aeccPipeFlowDirectionEndToStart Then
35: oPipe.EndPoint.Z = dLastElevation
36: End If
37:
38: End If
If you want to go back to the old way just copy over the changed C3DPipeRules.dvb and it
should be back to the original state. You can download a hacked version here if youd like to
review.

Advanced Daylighting Design and a farewell...
Hi all - this design scenario came up a few weeks ago, funny enough from two different sources,
in Europe and North America. How do you design an Assembly that in cut conditions daylights
from the hinge point and has two parts (see below); first a variable dimension (x) and then a
second part with a fixed dimension (y)? As you may know, at first glance Assemblies can only
have a variable dimension on the "last" daylight portion, where you just tell the Subassembly to
find the surface wherever it is. This seems impossible - how could we achieve this?
To understand the solution we will quickly review the definition of a parallelogram. It is a
rectangle in which the opposing sides have equal length, like this:
Look at the X and Y portions in the first graphic and compare - any ideas? We DO need to start
with a fixed variable and end with a link to find the surface, but here's another hint - you can
create Links as construction items and use the "Omit Link" property. Stumped? Let's take the
design criteria and combine it with the parallelogram concept to get a solution!
Part 1
Use a LinkWidthAndSlope to create a fixed daylight offset
Then add a LinkSlopeToSurface
This is exactly opposite of what we want, right? On to Part 2...
-
Chuyn thit k ng trong Civil 3D
BQT din n www.kythuatdothi.com Trang 54
Part 2 - now we are going to go "backwards" to get the links we actually want.
From the daylight point at the surface, create the same LinkWidthAndSlope, but in the opposite
direction
Then add a MarkedPoint to the end (give it a name when creating)
Now from the original hinge point, attach a LinkToMarkedPoint and provide the MarkedPoint
name
See what you have done, you have created a parallelogram! Now you need to go back to the two
subassemblies you created in Part 1, right-click and Edit Subassembly. In the Subassembly
Properties, just turn the "Omit Link" property to "Yes." Now those subassemblies are just
construction pieces and will not be drawn when you create your corridor. Perhaps now your
horizons have opened up to other possibilities - my thanks to Tomas Lendvorsky, Autodesk's
Solutions Engineer from Prague (he's a whiz with Expressions too!).
