I have a client that wants to put in a constant flow into an inlet and have SSA calculate the HGL downstream of that (as well as add additional flows at additional inlets). Is there a way to do this? I tried adding an "Initial flow" to a pipe but after running the analysis, that flow wasn't the peak of the pipe (I used 1cfs for the initial flow and the peak was 0.77 cfs).

C3D2012..I have an assembly with left and right curb subassemblies, they are spaced about 1 m apart. I want to connect the BOC's with a constant slope median. I bring in the median and connect it to the Left BOC and it attaches, but shoots the median for 20 m across the assembly to the right. I tried to put a marked point on the right BOC prior to bringing in the median assembly, but the same thing happens. I changed the marked point name to RTC (Right Top Curb) and also changed the name to match in the median subassembly, with the same results.
Any proper way to insert the median and get it to connect properly.
I know it can be done usign Pipe networks and feature lines and a massive waste of time.. But I just want ot offset my FG to show a line constant offset. Can this be done? If so how?

I'm attempting to model a gas network using the pipe tools (Civil 3D 2011). The problems I'm having:
1) The pipes are coming in at all depths (mostly too deep), rather than at the constant 3' cover I would like.
2) Pipes all have zero slope and "stairstep" at null structures, instead of sloping with the surface.
My pipe rule set is:
Cover only, min/max 3'
Match pipe-to-pipe, inv 0'
I tried adding a slope rule, it dropped pipes lower.
For structure rules, I have tried both 0' drop across structure, and no rules (hoping pipe match would take over). All are null structures.
I do have the surface referenced, and it is being recognized (structure rims insert at grade).
I am modeling an existing storm system that is under capacity. After running the model, some of the flows seem to be incorrect. I have one section that has a known flow of 1.31 cfs. The results for this pipe section shows 28.82 cfs (peak flow during analysis) and 6.06 cfs (design flow capacity). The pipe section is a 15" with constructed slope of 0.0088 ft/ft. The max velocity attained is 23.48 ft/sec. I know that the downstream is undersized. Could this flow rate be caused by the downstream backflows? The model is setup as hydrodynamic and rational method. My inertial terms are set at ignore, time step = 0, junction surface area = 0 and variable time step with safety factor 75%. I have gutter bypass flows and my sag structures have ponded area set at 100.

View 9 Replies View RelatedI have a huge subdivision that we are about to do in civil 3d. The subdivision has over 1800 lots. I am wondering what is the best way to go about this. At the moment we are thinking we have to do the alignments, profiles and corridors all in one design drawing for it all to be dynamic? If so this file is going to be huge. Is there a way we can split it up and still keep everything dynamic?

View 1 Replies View RelatedI have a simple catchment area that I've routed to an inlet and then to an outfall. The 10 year storm peak flow going into the inlet is 3.91 cfs and my flow in the link to the outfall is 10.55 cfs. I do not understand why it is increasing going into the pipe. I've attached the pdf results here because for some reason it won't let me attach.spf file.
View 4 Replies View RelatedI am trying to figure out how big my pipes need to be for a storm sewer that I already have set elevations for. Every time I input the pipe and rim elevations for the network in the data tab it changes the inputs back to saying design. How do I set my own elevations for the pipe network?
View 2 Replies View RelatedI can't figure out how to reverse the flow direction on my pipe so I was going to just redraw it but after I delete a pipe and rt click to edit network the "add pipes and stuctures" won't let me add anything. I'm just guessing I need to reverse the flow direction because my invert out and invert in elevations are backwards in the profile. I'm working in Civil3D 2012.
View 6 Replies View RelatedI am wanting to get the peak flow back into Civil3d to add to our long sections, I assume the Peak Flow in SSA is the Flow rate property for the pipe in Civil3d, the HGL stuff seems to come in ok. I am just doing a basic rational analysis in SSA is there a trick to getting the data?

Is it possible to have pipe flow direction method set to "by slope" by default when we creating new pipes?
View 5 Replies View RelatedI am modelling a steep channel of constant slope operating under super critical flow conditions between two small weirs. I have set up two different models to represent this:
1. A single link between the upstream and downstream weirs.
2. I have also modeled the channel as a number of smaller links with the same slope separated by nodes spaced arbitrarily along the channel length.
The two models give very different results. The former results in an unstable channel (oscillates between sub- and super critical flow) and a maximum velocity in the channel of around 1.5m/s. It seems to me that the velocity in the upper section of the channel should be higher. I assume this has something to do with the manner in which SSA averages the velocities along the entire channel link.
The second model gives more realistic velocities in the upper channel links (around 3.6m/s) and a hydraulic jump and transition to sub critical flow upstream of the weir in the lower channel. This seems more realistic. I think the trick here is to make sure that the downstream link is long enough to enable realistic formation of the hydraulic jump in the model.
I am trying to create a new linetype using arrows to show the direction of a flow. I can get the outline of my arrow head to save as a shape, but have not figured out how to save the hatching to show up in a linetype. I need the arrow head to be shaded in solid. Also is there any downloadable linetypes out there for Civil 3D?
View 5 Replies View RelatedNow, in my understanding, the flow arrow should either be rotated 0, or 180 (pi radians). But clearly, some of them like to have their own mind about things, and decide on some other rotation. It seems that on the steep slopes, the arrows go a bit skew.
I think the skew is related to the actual elevation difference of the segment, rather than the steepness of the slope. A long segment with 15% slope has a worse skew than a short segment at over 30%, presumably because the elevation difference from the start to the end of the segment is larger.
I can't seem to find where to increase the flow direction arrow size on a watershed. Am accessing remotely, it's a bit laggy and bothersome, but doable. I looked all over Toolspace.

I want to create tables in the drawing where the points are and then plot them from a drawing they're Xrefed in to. The tables are too small but zooming in doesn't make them any bigger because the scale of the viewport changes and they adjust.
How I would be able to grab the block constant attribute by searching via tag.
e.g. block has a constant attribute 'Color' with value of 'red' and I wish to attain 'red'
I am currently obtaining non constant attributes using:
Dim attRef As AttributeReference = DirectCast(tr.GetObject(attId, OpenMode.ForRead), AttributeReference)
and grabbing the '.textstring' when looking at the '.tag'
How do I go about this with similar logic but pointing to constant attributes? I have tried searching thoroughly and almost all results for me were in VBA.

View 2 Replies View RelatedOk, so I just got a new computer after having to deal with "Not Responding" from my old computer all the time just to find out I still have this issue with a brand new computer. It's really frustrating because it will do this all the time with small assemblies, big assemblies, parts, it doesn't matter. It also can be at any random moment from rotating the model to adding a constraint to saving. It doesn't seem to have any real pattern it just seems to happen all the time.
View 9 Replies View Relatedin order to obtain a seabed profile for a school project, I need to get the Y coordinate of a polyline on several Kilometers with a fxed X step of 2m between each point.
For the moment, the only manual solution I have found is to create a vertical line every 2m and to get the distance between the intersection of this line with my polyline and an horizontal line representing the mean sea level.
Is there any way to automatize it because it is very long to do manually and I don't have enough time ?
I did not succeed in doing this with dataExtraction. I also found on the internet a LISP file which extract the coordinates of points contained in the window. Nevertheless, I was told it is not possible to create automatically points on a curved polyline with a fixed x step.
What I need at the end is an excel file of this type to use it in another software:

why I might be seeing this error? I get this as soon as I select the "Constant Speed" option. I haven't input any other values yet. I've already set the "constant speed" option on the animation timeline menu. I also only get this error when this sub-assembly is inserted into a higher level assembly. If I animate the same components in the sub-assembly file, it works fine. What am I missing? There are no parameters holding these components in place in this upper assembly either, that was the first thing I checked.
View 1 Replies View RelatedI am trying to determine whether or not the following is a bug:
1. Begin creating a new block using the block editor.
2. Add an object (circle) for reference.
3. Add an attribute with the following properties: Constant, Visible, Value (i.e. "34"), Justify: "Middle-Center." Make the tag
4. Save the block, exit block editor.
5. Insert the block into model space.
At least on my system, the constant attribute always shows up left justified. If I explode the block after inserting it, the constant attribute shows correctly. In addition, the constant attribute seems to be left justified with the TAG label from the block definition itself.
I've got a block that I want to scale in pspace, but I would like the attrib height to remain constant even at different scales. I have used annotative blocks in vports with much success, but I would like to do the same thing only in pspace.
