AutoCAD Civil 3D :: Finding Drain Pipe Daylight Locations

Aug 21, 2013

I need to rough in a drainage pipe network that connects several structures around a site. The pipe inverts need to be 6.5' below the finished floor of each unit and must maintain a minimum 2% slope. The network needs an outfall at some undetermined point on the site. The pipes must follow some existing roads, so they are not interconnected directly to each structure.

How can I go about determining the potential outfall locations?

AutoCAD Civil 3D :: Storm Drain Profile View Invert Labels?

Dec 30, 2013

I've attached an image of a storm drain invert label for a storm drain profile.  As you can see, the middle manhole has all three inflow pipes labeled.  Is there a way to only label the inverts of the two pipes shown in the profile view?

AutoCAD Civil 3D :: Hydraflow Extension - No Flows

Nov 7, 2013

New user for civil 3d and the hydraflow extension for civil 3d.  I have my pipe network created, all the correct catchments are attached to the correct basin/inlet.  i have opened my network in hydraflow and am ready to run it.   when I click run it says no flow.   Now I know there is another step i need to set my flow wth TOC, I've inputted that, i am using the standard idf curve hydraflow, i have the areas with their coefficients, however it is not calculating my flow rather it is telling me no flow is inputted for certain lines i.e. the ones with MH connections and no inlets. 

I have attached my .stm file to this thread, i changed the extension so it would post, just delete the .doc from the extension and it should work in your hydraflow.

I opened open project dialogue window here I copied and renamed a copy of the project file. When I tried to open either the original file or the renamed version - Hydraglow shuts down. The project file has attached dxf file as abackground. (see attached). I hate to lose a day of data entering given my tight deadlines.

AutoCAD Civil 3D :: Orifice Calculations In Hydraflow Hydragraphs

Dec 13, 2012

I can't seem to confirm the discharge table that hydraflow produces in hydraflow hydragraphs.  I think I understand the equation itself (it's been a while since I took hydraulics), but can't understand where I'm making my error (if I am).  Normally I trust the stage/discharge curve that hydraflow produces, but the City Engineer is asking me to confirm the values by hand and show them on the plans.  Is there a link to an detention pond example that shows how a curve (the outflow values) was generated (confirms the discharge table at various elevations)? The equation is on page 85 of the users manual.

AutoCAD Civil 3D :: 2012 / Hydraflow Constantly Crashes

Feb 11, 2013

I am running Civil 3D 2012 and my Hydraflow crashes everytime I run an analysis.  I am using a known Q and have input pipe inverts/slopes and pipe sizes.  Everytime I try running an analysis I get the following message:  Line 1, 2, 3 has no flow.  Check pipe size(s) and slope(s).  Then the program closes up.

AutoCAD Civil 3D :: Hydraflow Import Changes All Parts To Standard Style?

Jun 19, 2013

one would think that you could just export the .stm file into hydraflow, make some changes, and import, and all would be fine.  when i export, all of the structures in hydraflow come up as drop curb.  how can they come in as what they actually are.. aka, when the part i use is a 2x4 box, it should come into hydraflow as a "grate inlet", or a st-mh will come in as a "manhole".

and then likewise, when the changes are made, and its brought back into autocad, they all come in as a "standard" style.  except the outfalls, which show as a "standard" style, but come in with a different block, and get a whole new label (outfal - x)

Oct 30, 2008

When I try to run my hydrographs through a pond I get an error stating something to the effect of: Outflow greater than Inflow on Hydrograph 6 for the 50-yr storm.

How can the outflow be greater than what is flowing into it? How the program can calculate this.

AutoCAD Civil 3D :: Hydraflow Storm Sewers - Import / Update Storm Network

Aug 21, 2013

I am having issues with importing / updating existing storm network.

The problem is when I update the storm network, All the outlets are added as new structures. It does not update the existing headwall / end sections.

I then have to go thru and delete the added (null) outlet structure. Then, reattach the existing outlets to the pipe network to show up in the structure data table correctly.

AutoCAD Inventor :: Drain Care Spring

May 29, 2013

Inventor  offers us several options to design a coil of constant pitch with a tapering diameter.  However, I am unable to create a coil with a taper and a changing pitch at the same time.

We are using Inventor 2013. I would like to produce similar parts as the attached 2D drawings in 3D, only with a changing pitch (distance between revolutions) per revolution.  Can it be done?  There is software for the CNC spring manufacturing machines to produce such parts. Therefore the proper inputs to produce these effectively and efficiently, are available somewhere.

The part I've been describing uses .09 diameter wire and has about 54 coils in about 8 inches. The starting inside diameter is about .53" and the pitch is about .27" the ending inside diameter is .109" +/- .01 with a pitch of about .091".

Here are 2D drawings of similar parts, the last (NF3) is closest to what we need.

I'm trying to model a ceiling mounted arm system with the possibility to change arm lengths and angles.

My problem: I have a box with a cylinder attached to it. No problems there. Then I have another box which is the first arm of the system. I want the arm to move when I change the length of the cylinder so that the arm is always connected to the cylinder and the cylinder always connected to the other box.

AutoCAD Civil 3D :: Section Of A Model As Its Own Model

Sep 11, 2013

I am currently using AutoCAD Civil 3D 2010 for surveying work and have been trying to figure out how to use part of an existing survey of land model.  I have it in a layout (paper space) and used a viewport to get the section I am after but there are some changes in labeling and minor model modifications needed to make it a stand alone model and I do not want to modify the original model to make these changes.  How can I take a section like I have in view port and make it into its own model with a different scale so the changes can be made and the original model is left in tact?

AutoCAD Civil 3D :: Field Data For Surface Creation

Feb 1, 2013

I have a 1 mile road topo coming up for design purposes.  The curb is standard, but there is full curb & depressed curb.  If you had your way from the CAD seat, what shots do you prefer?

Most accurate I've seen iis Centerline, Edge Pavement/Edge Concrete Gutter, Flowline Gutter, Face Curb, Back Curb.  More fieldwork, but made a good product. 

What I have seen is CL, EP, BC, then "let them just use a template" and several variations thereof.  

I have never seen a good way to automatically offset from say BC only and  handle depressed curb by field coding.

AutoCAD Civil 3D :: Update Field Isn't Updating As Expected

I have a field in a block and all the FIELDEVAL variables are set as shown in the screenshot but the field doesn't update on REGEN - I have to issue the UPDATEFIELD command to update the field.

There was a previous thread started in March 2011 with the same problem - is this another unresolved bug? (No connection with Autodesk other than using the products in the real world)

AutoCAD Civil 3D :: Post Processing And Field Book Files?

Sep 30, 2012

We use Trimble data collection software.  We typically import a "rw5" file converted from the "job" file.  We then convert the "rw5" file to a "fbk" file.  The conversion process has some bugs in it..

We have found two problems (thus far!):

1) The backsite data, for a station set-up, gives back an error when we reduce the data into the survey network.  It also tweaks the coordinates for the set-up point.  We have fixed the error by noting this line of data in the "fbk" file.

2) When the field doubles angles (wrapping, turning, etc.) C3D use only the first angle turned and not the mean or averaged angle.

We have found that if Trimble Geomatics Office (TGO) is used in post-processing, the "fbk" file generated works on both counts. FYI, the Trimble ribbon does exactly the same thing as C3D when a "job" file is imported, i.e. does not work properly.
