I have a few questions regarding spread/street capacity:
When calculating the spread at the catch basin locations, how does it determine the curb height?? Does it always assume 6"?? what if it is a roll curb??? is it olnly determined by the "throat height" of the inlet?? How can I calculate my spread on random spots throughout the street??
I've created a network of my stormsewer (which means the stormsewer lines are all on different streets) and added the inlets to my street profiles.
How do I get the profile structure labels to reflect the stationing from the street alignments?
how can i insert open street map file (osm) in autocad civil 3d 2012.
View 5 Replies View RelatedI have a single street alignment that looks like an “n”. My issue is the west side of the “n” is named “Main Street” & the east side is named “First Ave” in the real world. Is there a way to have an alignment name from station 1+00 - 10+00 be different than 10+00 - 20+00 for automatic label purposes? I would rather not break the alignment since it one long continuous street & in some instances there is a vertical curve within the breakpoint. JUst need to figure out how to use automatic lables for naming street intersections.
Using C3D 2010 but curious on newer versions too.
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.

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?
View 4 Replies View RelatedI have a ~8.1MP image that I want to get printed on a pretty large scale. However, there are a few spots on the image that I am going to need to remove.
(Picture file here.)
There are 4 large black spots (circled) that I am sure should not be there. I am pretty sure they were smudges on the camera lens, because I have the entire set of images that was shot in this same jump, and those 4 spots are in the same place in all of them.
However, there are also a lot of white-ish spots scattered about the upper half of the image that seem to be mainly near the ends of the "sun-star effect" (which is one of the coolest parts of this picture, IMO). They don't seem to be present in the other pictures from the set, but perhaps they are also lens smudges and only show up in this one because there is such bright light hitting the lens, making them noticeable.
Are the white spots part of the attractive sun-star and should stay?
Are they smudges on the lens and should go?
Are they part of the sun-star but should go regardless because they don't look good?
Does the sun-star even look good or am I crazy?
Bonus question #1 - Are the red, yellow, and blue "hexagons" (noob terminology here) attractive? I kind of like them, but what do photo pros think of these things? Lens flares, they're called, right?
Bonus question #2 - Should I make the image brighter, so more color in the jumpers and their suits can be seen? Or should it remain this dark, since it is in fact a silhouette?
Before I spend the $25 to make a poster-sized print for my wall, I want to make sure I get the image looking good. The 4 black spots, I think I could probably remove without too much hassle (limited Photoshop skills here). But the white spots would be harder I think... for one thing there are many of them, and for another they occupy the same space as the sun-star, which I don't want to screw up.
I don't know about open traverse...how to do open traverse and how to adjust it.
View 3 Replies View RelatedWhat formula Civil3D uses to calculate the average slope of a surface?
The formula I am using is S = I*L/A
S = Average Slope
I = Contour Invertval
L = Length of Contours (ft)
A = Area of parcel (sq. ft)
I just had to do four parcel calcs and the percentage I find using the formula is always 1-3% lower than the percentage Civil3D spits out. I can't find anything about how Civil3D arrives at that number, it just appears. I assume that Civil3D is more accurate but I can't give that number to a client without knowing how the program arrived there.
Trying to calculate a catchment area to allow me to size some culverts using Civil 3D 2012 Sp#1.
" The specified location results in a Catchment with no area."
After sitting for 15 miutes I keep getting the above message. The surface is huge and there is an obvious catchment area (or I think it is obvious). The surface was generated from contours and cover an area of approx. 8Km x6.5Km but the catchment ares should be around 15-20% of that area.
I tried another one upstream about a Km and it worked fine. So the one I am doing now should encompass the upstream area as well as from that point downstream to the Discharge Point.

All we have is an alignment and a surface. In one region we need to calculate the stripping that is 6m wide x 1m deep.
I used LinkOffsetOnSurface to get the surface elevation on the left and right side.
I then tried using the stripping subassemblies but no luck.
because we have a number of regions and assemblies we would rather use corridors than creating a stripping surface.

View 6 Replies View RelatedI’m using 2011, due to printing issues in 2013. My question relates to determining how runoff gets diverted, or spreads out, after leaving a well defined channel.
I have a street intersection scenario. It’s a “Y” situation in which the main trunk of the “Y” is curbed and contains all the water for the three storms I’m studying. Runoff flows towards the two streets that branch off. I need to know what percentage of runoff water splits during the 2-, 10-, and 100-year storms from the main (curbed) roadway to the other two streets - one curbed, one uncurbed.
I assume that velocity, runoff volume, storm intensity, street cross sections, slopes, and other variables play a big role in how the water diverts, but I’m not sure how to set up this scenario in SSA. Do I somehow use a weir? Do I use an open channel, or user-defined channel? I have a subbasin area defined with my concentration point at the end of my main curbed street before the water splits off. I’m not sure where to go from here when it comes to inserting links, weirs, channels, etc.
how I can set this up? I’m not even sure it’s possible to have the software provide this type of calculation.
As I was creating a surface consisted of contour lines, suddenly some bunch of random points in the surface were also created. I want my surface to be solely generated by contour lines only. So...
I know I can get rid of those points by deleting them through edit but I want to get rid of them all at once. How can I do that? Or... Is there even a way to do that?
My C3D 2013 just started doing this last week... I first noticed that it would zoom to extents when I operated the center mouse button for panning. It was random, about 1 out of every 15 to 20 pans using the center button.
But then I noticed that it's not just the panning. It will randomly zoom to extents when I type in a command. Earlier today, it did it when I did a REGEN, then again when I did a MAPWSPACE.
The other notable thing is that there is no "zoom" command anywhere in the command history when this occurs.
Besides changing the mice, I also tried rebooting and running a repair on C3D. I have Win7-64.
The problem seems to coincide with when I started using Autodesk 360. Not saying it's related, but it's fishy.
In the past couple C3D versions, I've had these random borders show up in my simple tables. I have a table for my legend and another one I use for a list of references. I use no borders for these tables but sometimes when I edit a cell somewhere in the table, the random border will appear. I remove it and then sometimes it reappears again later. It's usually the top line of the second row, second column only but occasionally it will be when I add a row into an existing table.

I have an acad document connected to some .shp files, which contain polygonal shapes with some meta-tags.
I want to achieve the following: draw a polygonal shape and select all the tangent areas (I already know how to do so)take a property of those areas and calculate an area-proportional [or: area weighted] average value (proportional to the partial area defined by the drawn polygonal shape). I tried to achieve this by splitting the objects and merging them again with defined splitting (area proportional) and merging (average) options. The problem is: splitting & merging doesn't work until I disconnect the data files (checking the objects out doesn't work) and even then I can't split the areas. And, more important: This doesn't create a weighted average and I don't even want to manipulate the objects! I just want to get one value out of all these steps.
I appended a screenshot of my file. E.g. I want to take the value 923.2 and multiply it with the corresponding area percentage it represents in the drawn shape. So the calculation would look something like 0.02*923.2 + 0.2*926 + 0.12*945,9 [...] until all the 100% are covered and I get one single representative value.

I've got a user who imports points into the survey database and RANDOMLY the points will be shifted on average 27 feet in the northing and 4 feet in the easting. She notices this because she'll check a point and see tht the northing and easting varies from the grid northing and easting (I've attached an image to view) She will then discard the drawing and begin a new one only to import the data and now it imports correctly. The behavior is completely random and it's happening on multiple projects.
All the projects begin with the same template. All the settings (drawing settings and survey settings) have been set to US Survey Foot. It's weird because once the issue is noticed it can be fixed by simply beginning another drawing and re-importing the data, but it has happened on projects where she's already got pre-existing data.
