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 need to model a diversion manhole in a storm sewer system. The diversion will take X cfs from the system and send it to a water quality treatment facility. After leaving the WQ facility, it will be returned to the storm sewer system at the next manhole downstream.
I tried in Hydraflow but it doesn't look like diversions are possible. Thought about modeling up to the diversion manhole and taking that data into some other program, and then coming back into a second Hydraflow model that handles the downstream bit.

I have a master plan development that I am trying to model different wastewater flows scenerios for I am basically following this paper from AU 2011 [URL] but have a couple of issues I am trying to work around.
Basically I want to take a spreadsheet of flows determined for specific nodes and upload it into SSA quickly from the paper
I can see that you can write a shp file of the network and then add different flow scenerios to the .dbf file and them use the GIS import function of SSA to get the flows assigned in one hit.
The issue I have however is that my network is a prelimary design in Civil3d as pipes and structures and if I create a .sdf of the network and then.shps from that data I do not get the structure sump elevations, this is not something that created in the shp file export process,
To work around this I through maybe I could export the network from Cicil3d to SAA which gies me all the strucutres with the correct sump levels and then also create a .shp and .dbf file and add the flows and them do a GIS import of just the structures and merge them with the exisiting network as the structure names as exactly the same and therefore the gis import should find the correct structures.
However SSA does not and adds a second lot of nodes with the same structure name but with Junction in the front.

I am having difficulties modeling culverts within my model for the 100 year flow. I have seen the sample file within SAS, and all of my culverts have a storage node at the upstream end with a weir representing the road. However, when the weir is utilized, peak flows are artificially high. For example, despite a basin only producing 11.7 cfs, the weir has 8.94 cfs and the pipe has 10.35 cfs. I am using hydrodynamic routing with a 5 second routing time step.

I opened Hydraflow Sewer Extensions and created a project. I was able to save it and open repeatedly without problems. 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.

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.

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.

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)

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.

We are seeming ot have problems with a few of our engineers having the Microsoft Office product go to "Not Responding" and then closing while working in Hydraflow & Hydrographs. This has been with Outlook, Word and Excel. All workstations are 64 bit systems with 16 gig of Ram Windows 7 and Civil 3D 2012 SP2.1.

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.

We are working on a road widening scheme where one edge of the road is retained as far as possible while other edge being widened. I like to design a retained channel line by extending the cross fall between the existing center line and the exiting channel line on to the design one.
It is possible in civil 3d to extend the gradient between two feature lines at some offset from reference feature line?

I'm learning how to create extension (flex - extension builder) for Illustrator and how to make it communicate with a plugin.
The samples provided in the SDK detailed how to load /unload extension from a menu item from Illustrator, and how to add / remove EventListeners to make the magic happen.
to sum up, this is something like that:
1- click on the menu item
2- load extension
3- add listeners
4- do your stuff......
5- remove listeners
6- unload extension
Basically my plugin is a module/service which is in charge of dealing with / modifying artwork tree. It has no User Interface.
My extension will have a user of this service.
What I would like to do is to load my extension as soon as my plugin is loaded, and unload the extension when the plugin will be unloaded.
Or notify when extension is loaded or unloaded.
Is that possible and hw could I achieve that?

I'm using Inventor 2011 and I can't figure out how to set my dimension settings so it breaks the dimension extension lines automatically when crossing over other dimension extension lines. I saw that others say it just happens, but it is not "just happening" for me. how to set my dimensions so when dimension lines cross each other one of them automatically breaks?

I'm working on a document with tables, and when I ask it to autoflow, using the Shift- Click, after the first table, the rest of the tables are on one page, with long cylindrical text boxes, instead of the pages with large textboxes on them.

know of a conversion strategy to get a DEM file that has IMG extension into Map 2008?
We do have Arcview, which will open the IMG file (ERDAS Imagine raster format?), but it will only save this as standard raster formats (jpg, tiff). I am doubtfull that one can use these formats as a DEM in Map.

I have a finished plugin (dll-A), which works well.Now I want to write an extension for it (dll B).The function in the expansion are so special that I do not in want to integrate the finished plugin (dll A).I bind the dll to the plugin (dll-A) into the new dll of the plugin (dll B) and inherit the plugin class (class A) in the plugin class (class B).Is loaded by the netload (dll B).
Autodesk.AutoCAD.Runtime.Exception: eDuplicateKey bei Autodesk.AutoCAD.Runtime.Interop.Check(Int32 returnValue) bei Autodesk.AutoCAD.Runtime.CommandClass.AddCommand(ICommandLineCallable ca, MethodInfo mi) bei Autodesk.AutoCAD.ApplicationServices.AutoCADApplicationHolder.Initialize(Assembly assembly) bei Autodesk.AutoCAD.ApplicationServices.ExtensionLoader.ProcessAssembly(Assembly assembly)
Exist in both dll's no duplicate commands!
On debugging looks as if autocad load first dll-A and than load dll-B.
Can it be that the (dll-A) is loaded twice?
