AutoCAD Civil 3D :: Multiple Inverts From Junction / Inlet In SSA
Jan 24, 2013
I am working on drainage for a median storm sewer, culverts and ditching for a large freeway expansion project. Â I have median storm sewers running down my entire roadway (about 5kms). Â I have manually inputed the upstream and downstream elevations of the pipes in SSA, but when these pipes are connected to an inlet or junction, I only have the option of selecting one invert elevation for each structure (I am actually using a lot of catchbasin manholes in this project, which I am unsure of SSA's ability to model). Â I have multiple drops of varying elevation differences throughout the project, with some of these inlets/junction requiring drop structures due to the large difference in elevation change. Â How do I properly model this in SSA?

Messing around with MAP in Civil3d 2011, creating object data for sanitary sewer manholes, how do you handle object data for inverts since there could be multiple depths and directions. Whats the best way to set it up? And what kind of addtional info should there be. And when I connect to a shp file, how do you label with multiple lines, I seem to only be able to select 1 feature to label. When zoomed out would like to view structure name and when zoomed in view name, rim elevation, invert elevations.

I've changed my workflow slightly and have created 4 junctions via the wizard but kept them all in the same Corridor (previously I kept each one in its own corridor).
I now need to create the formation surfaces for the corridor (in the way I always have done it) but only one of the junctions has a surface. I then added a show boundary and the "missing" surfaces appeared but with many connecting triangles and superfluous triangles in the curved areas.
How to get a nicely shrink wrapped surface or is it a matter of brute force removal of triangles etc?Â

Is there a way to change the default Style Set that is used by the tool?
I don't want [All Codes] to be used, and since I created a style for the project I'd want to be able to use it when creating corrridor using the tool.
Toolspace Settings seem not to have relevant option.

I'm drawing existing SD pipes and trying to put in rim and inverts of the existing structures. Sometimes it won't let me raise an invert to where it really is. It only let's me raise it so far. It may be a rule but it doesn't seem to be a rule I can change.

below is a portion of a profile i am working that shows the bottom of the catch basins not at the correct elevation the correct elevation is at the pipe invert the dashed line by checking the structure properties the cb are at the inverts are correct but the actual drawing is not shown correctly.

After testing a simple culvert and pipe, it appears that inlet control is not checked for pipes. Does this mean that I have to model all storm sewers in a network as culverts just to check inlet control?

I do not have two outlet from 4 different intakes. The four intake are modeled as on-grading intake and do have both a bypass link and pipe line attached. Attached is the model that I have been working with. The intake causing the problems are:
EX.I-01
EX.I-02
EX.I-05
EX.I-06

Is it possible for a civil 3d structure to be displayed correctly in profile view when the alignment does not pass through the insertion point of the structure. See the attached screen capture.
The rectangular structure is a storage tank and there will be a pipe coming in on one end and the exit pipe will be on the adjacent side at the far end, just as the alignment shows - but the structure doesn't show correctly, or now how I expected.

I have a source drawing with a proposed surface, alignment, and pipe network. When I data shortcut these objects into a new drawing, everything comes in correctly except the pipes. The inverts are incorrect. The pipes maintain correct slope, just the inverts on both ends are off. The structures they are attached to have the correct rim and sump.
I have included a screen shot of the properties box for the same pipe in the source and referenced file.
I'm at a loss. I have made sure the parts list and rules are identical in both files.

Any hydraflow calculates depth of flow and spread at sump inlets? Does it assume that the entire flow is coming from one direction (similar to an on-grade inlet)? Or does it make an assumption about how much flow is coming into both ends of the inlet?

The SSA literature states to use an On Sag inlet to model an inlet used in the middle of a parking lot.
This is more commonly known as an "Area Inlet" application, and is also used in areas such as airport runways, greenbelts and golf courses.
To develop the correct operating head relationship over the grate, we need to be able to enter a stage-storage curve starting from the grate elevation. This will develop the "cone" shape storage needed to develop the correct head elevation over the grate.
It appears looking at the On Sag options there is only the Ponded Area parameter available; the same parameter found in a Junction. This calculates the head elevation as a function of the ponded volume and a constant area.
Â
I want to confirm that the On Sag inlet application used as an Area inlet, is using all four sides, full perimeter = 2(L+W), Â of the inlet for the weir flow calculations before orifice flow controls, not just 3 sides as a grate on a curb.Â

We recently began experimenting with SSA and are trying to verify the inlet calculations that were done in excel to make sure we understand the software before putting it into everyday use. We've created a custom parabolic street section and applied it to the bypass links, and as far as that aspect goes, we understand it and it's all working great.
How to model inlets directly across from each other in a street section. The issues arise when the top width (of Inlet 1, in the attached graphic, for example) exceeds the half section width and flows over the crown into the opposite side of the street (to Inlet 2, in attached graphic).
We have tried weirs and flow diversions to no avail. Attached is an example of what I'm trying to explain. Inlets 1 and 2 are opposite from each other, and both connect into a MH labeled SD-J 29+33.00. Link-05 connects to the next downstream MH, and there are 2 links that follow the gutter lines to the North used as bypass links from Inlets 1 & 2.

I would like to know if it is possible to display the pipe inlet/outlet elevation in my structure label. It seems like it is not possible.It is possible to use the inlet/outlet elevation of the pipe in my pipe label however I would like to display it in my structure.

I created a pipe network from a object (alignment wLpolyline) I want to set my inverts at the inside edge
of my SDMH not the center. I go into Edit Pipe Networks then the vista (table). I don't see a option to do that.
Is there a setting in the SDMH structure style or somewhere else?
As an example I come in at 6250.0 at inside a 48" MH and go out at 6251.0 at other side of MH.
I wanted to use a catch basin that shows the depressed curb & lip like the one in the Pipe Network Video
but it not in my parts Library even when I create a full parts list it still isn't there. Is ther a way to go on line and download part structures?

I have created user defiined properties to add up to 5 inverts to a topo point object. Â Each consists of the direction of the invert as an enumerated list that can be picked from (N, NE, S, SE, etc) and the second is the measured distance from rim down to IE. Â I created these in order IE1_Dir, IE1_Meas, IE2_Dir, IE2_Meas, etc and the first time I used it everything worked fine and was in the proper order. Â Now after opening the drawing for a 2nd time all of the UDP's are scrambled making it a bit of a PITA to enter into the proper fields.
I do not see any logical order to why it is displaying this way as if it was in order of creation or alphebetical it would not have changed. Â Is there any way to correct this or is this a case of Civil 3D is going to do whatever it wants to do?

I have ran an analysis and SSA gave me Error 607  on the report. It says "Inlet A9 gutter capture curve is not a valid curve."
A couple things I did different from the video lectures...
IÂ selected user define for the Tc to figure out Q. i computed those manually.
For the Inlets I have selected Maximum Capture Cutoff.
There are some inlets in this model I created that do not capture 100% of the flow so i created conveyance links to account for the bypass flow.Not sure why is not recognizing the Curve?

After having a "&%#¤¤#%¤"-moment and taking it out on my keyboard I've made my brushes invert what I'm doing instead of actually painting with the color it's supposed to. I'm working in b/w, so what was white turns black and black turns white. And how can I undo it. Restarting photoshop didn't work.

How to accomplish, and I've searched various places, is how to have a layered floor structure dovetail into a layered wall construction.
Â
I have a cavity wall construction with inner leaf of blockwork - and an intermediate floor slab - concrete precast slabs with insulation and screed on.
Â
The construction in Revit defaults to the whole floor structure finishing at the internal face of the wall. I need the slab layer of the floor to project into the inner blockwork, whilst having the other floor construction layers finishing flush with the wall. This needs to occur at the support end of the slab only rather than around the whole floor perimeter.
Â
I'm working on a single wall type spanning ground floor up to the underside of the roof - should I be using separate walls for each floor ? (I read somewhere that it is advisable to break wall types by floor as costs may be different).

I need to figure out a way to sample multiple surfaces for multiple alignments.
Example 1: I am creating cross sections for a river dredge showing the pre-dredge bathymetry, design dredge elevation, and post-dredge bathymetry results. I have 100's of alignments that I need to sample 3 surfaces and display in profile view. Due to the clients requirements for display, using the cross section tools don't work for me, so I have resorted to using a seperate alignment for each cross section.
Example 2: Working in a subdivision with many utility alignments it would save quite a bit of time to be able to choose a group of alignments and sample multiple surfaces in just a few clicks.Â

I am trying to figure out how to had multiple vertices to a feature line. I'm thinking its right in front of me, but I'm just not seeing it. I have been adding vertices by "insert elevation point" manually and it is a really nice feature in that it picks up the elevation that is already attributed to the feature line, but it would be nice to speed up the process.

I am using Civil 3d 2012. Â What I have is a surface along railroad tracks. Â Each set of tracks has a different alignment because they aren't parallel. Â I have a baseline alignment with my stationing set on that. Â What I want to do is have one profile view showing the multiple track alignments based on the baseline alignment. Â I can't use the offset alignment because they aren't parallel. Â

the issue is when i try to publish multiple dwg files which containing civil 3d objects including data ref to pdf it won't do it other whatever drawing is currently open.i kinda can see why. because the data ref reading is not programmed in when "invisibly" opening the cad files. xref are autocad native and it works.
so no warnings or anything. just publish the first one and told me it's done. i've seen this years ago when first started using civil 3d but then i just never complained here.
is there a solution for this? what i did before was obviously open each drawing. then publish, huge waste of time. making me hate my job because of repetative tasks. i almost always try to automate.
yesterday made a program to make one surface for each csv file there was hundres of them and basically 2 hour programming and 1 minute to process the files once got the program working.can read subfolders to find csv file too.

I'm finding myself on more and more sites that use multiple coordinate systems and height datums.
We have 3 on this job. One is the MGA zone 50 GDA94, another is just an offset of this and the third is a strange local grid with offsets and rotations.
We have Excel spreadsheets that can convert between the systems, but that requires several extra steps per point.
Is it possible to define each coordinate system in one drawing so that I could select which system I wanted to use, input the points and then select the main coordinate system so it converts the coordinates directly? It would mean less steps and I would have greater confidence in this system.Â
We have the parameters for all systems.

One of the problems we face in 2010 is the part labeling issue, where it labels the family name for a part and not the description name. The way to get around this was to do a swap part. Well for me when i lay out a storm network, i create it by pipes only and then swap the parts that i need to. The only flaw about this is that you can only do one swap part at a time.
Well if you go to civl3dreminder blog site there is a fix for that. I actually tried it and it worked. I was actually able to swap pipes and structures at the same time. This routine will definitely come in handy.

Is there a way to delete multiple VIP's in a profile? By windowing maybe? I have a profile with several hundred VIP's and I need to delete the VIP's between certain chainage but I'm not clear if this is possible. It will take hours to delete them one by one, although as far as I can ascertain this is the only way.
