AutoCAD Civil 3D :: Using A Surface For Volume Calculation?

Sep 25, 2012

I have run a volume between two surfaces, I need to further to break that new volume surface up to get volumes for each section. I know in microstation you can fence a volume surface and it will tell you the volume for that area. Is there a function in civil 3d that works like this. I know I can break it up manually and create new surfaces, I am looking for a time saving appoarch and trying to minimize file size.

AutoCAD Civil 3D :: Volume Calculation Of Dirt Excavation

Apr 14, 2013

how to calc dirt quantities in Civil 3D. Not just on roads, but say you have a small mountain of dirt that needs to be hauled away, and the contractor asks if you can quickly tell him how much dirt is there. And subgrade quantities for pads. Things like that.
First off, I'd need to learn the correct terminology. Knowing what to call stuff can at least make you sound less stupid when you ask a question.

AutoCAD Civil 3D :: Volume Calculation For Faces Object?

Jan 9, 2013

I have a volume in my CAD file described by 3D Faces. Is there anyway to know what is the volume of this volume -that represents an open pit-?

Every time that I do a volume I do by the comparison of 2 surfaces but this is not the case now.

AutoCAD Civil 3D :: Volume Calculation Method - Cut And Fill Are Not Even Close?

Sep 4, 2012

I'm to compare volumes in c3d to Inroads. My volumes are not matching ( cut and fill are not even close). Civil 3D uses  the average end area and InRoads uses 'triangle method' to calculate the total volume. How can I get C3D volumes to match InRoads which is verified correct?

AutoCAD Civil 3D :: Minimum And Maximum Elevation In Volume Calculation Summary

Jun 30, 2012

What do the data in the summary of volume calculation mean? In LDD, typically the minimum and maximum elevations are within the range of elevations where the volume is being analyzed. In my current vol calc summary it shows something that really makes me frown, e.g, min elev of -26.00 and max elev of 752. I have checked all the proposed elevations and the minimum is 720.

AutoCAD Civil 3D :: Sample Line Volume Report And Surface Volume Give Different Quantities

Jun 18, 2012

I'm working with TIN surfaces, doing cut/fill comparisons for a surface mine.

My volume surface statistics show a cut volume of 5167.22 cy and fill volume of 8456.18 cy.

The sample line group volume report show cumulative cut of 5527.67 cy and fill of 8465.56 cy.

What could be some causes of this disparity. All reference surfaces are built from points and use a non-destructive boundary.

AutoCAD Civil 3D :: SSA Storage Volume Is Double Of Pondpack Volume

Apr 24, 2013

I want to use it as my primary hydrologic and hydraulic modeler.  It only makes sense.  Well, I got the program to work and had things linked in and was able to route a storm through the network.  But when I routed the storms, I had to model double the storage that i expected.

So I went back to the program I'm familiar with - Pondpack by Benltey - and designed the same system I routed in SSA in that program - and got the storage volume that I would expect for a site of this size - about 2 acres.

Is there possibly a setting that I'm missing that makes my outlet structures route slower or less than they should?  Or is there some other reason that a system would give this kind of inflated need for storage?

AutoCAD Civil 3D :: Volume Boundary Creates Incorrect Volume

I have an issue with using Bounded Volume or Adding a Boundary to Volume Surface things so bad... = incorrect volumes.. sometimes extremely incorrect.. I understand that the surface rectangle when a boundary is added but this could be horrible if not checked.

AutoCAD Civil 3D :: Stripping Calculation In Surfaces And Corridors

Aug 8, 2013

I've recently started working with Civil2012/2013 (bit the bullet you might say).

I attended a course on civil about a year ago but it didn't cover all the bases.

My question: stripping calculation, is there a way fro civil to perform it automatically?

One way to calculate stripping (manually) is after i have all the tin volume surfaces, is to show the fill areas in the volume tables and then do the calculation myself.

AutoCAD Civil 3D :: Calculate Area Using Polyline - Calculation Not In Square Feet?

I was just wondering why when I try and calculate an area using a polyine, I am getting a readout of 1.80401967E+07, when I have it set to give me the calculation in square feet? It is an area of approx. 246 this because the area is so large? I am not sure what the "E" stands for or the "+07" at the end....

AutoCAD Civil 3D :: Volume From Surfaces

Sep 6, 2012

i'm jumping into 3d late in life...playing with volumes. i've created surfaces from aerial surveys and have saved the surfaces as separate files. i would now like to run volumes of the two as they represent the same quarry site from different years. it appears (?) i need to have both surfaces listed in prospector to run volumes. each separate file has its own surface listed. do i get (import?) the second surface drawing into one of the files so i have both listed and can run volumes? i see where i can create a surface from importing a .tin file...but i don't see how to export the surface as a .tin file.

AutoCAD Civil 3D :: Volume Of Fill

Jan 7, 2013

I have an existing survey surface, and I want to know how much cubic yard of materials to fill up from the bottom to elevation 876. See attached image for detail. Here is what i am going to do....

- i will create a surface of the fill area (from bottom cotours up to el 876) then do a volume surface bwt existing ground surface and the new fill area surface to get the volume of it? Is this a right way to do?

AutoCAD Civil 3D :: How To Get Volume Of Earth

Jun 4, 2012

I'd like to do a grading in order to get a volume of earth work needed.  It's a very easy proposed surface, but I've never done a grading before.  I have a surface that is basically a football field that is graded from one end zone to the other with a slight uphill grade.  At the end of the uphill grade is a berm the length of the endzone.  That berm needs to be higher, and the uphill grade from endzone to the other endzone needs to be flatter.  The dirt that comes out of the flattening will be pushed up on top of the berm on the opposite endzone to make the berm taller. 

The new surface should start at existing grade on the low endzone, go on .10% up to the other goaline, then on a 2:1 up to 24 ft above the low endzone elevation.  Think of a firing range where you shoot from the low endzone into a berm on the far endzone.  The berm isn't tall enough, so they need to find dirt from the surface to put on top of the berm.

AutoCAD Civil 3D :: Surface Volume And Display

Jun 3, 2013

I have a couple of questions regarding surface volumes/analysis in Civil 3D 2014.  First, there used to be a way to determine the volume between two surfaces without creating a volume surface.  The command is _AeccReportSurfaceVolume, but I can't find it on the ribbons in 2014 to save my life.  Do I need to create a new button myself?

Second, and more important, dealing with the elevation analysis in 2014, and noticed that the colors reset anytime that the volume surface is rebuilt?  It has always been annoying not to save a color scheme, but at least once you had set it up, the colors stayed as the surface changed.  Is there a new setting that I am missing, or is this just a glitch with 2014?

AutoCAD Civil 3D :: Reusable Cut Volume By Station

Oct 22, 2012

Within my road corridor, I have one section where the excavated material cannot be used as fill elsewhere.  I see a place where I can specify a factor for reusable volume when I compute earthwork materials.  But it looks like I can only use 1 factor for the whole corridor.  Is there a way to say from Sta XX+XX to Sta XX+XX the reusable fill factor is 0, but the rest of the project it is something else?

All I can think to do is copy the quantity report to Excel and manually change the reusable volume in that station range to 0.  But, since the report comes in as just numbers (no formulas), I then have to enter all the formulas to recalculate the volumes.

I have a large 200+ acre site that I have created a volume surface and analyzed it using the elevation banding with color to show different levels of cut and fill.  The owner has broken this area into 10 different irregular zones.  Is there a way to do the elevation banding of a volume surface and have it color the individual parcels.  They don't all have to be at once.  I can do each one at a time and PDF the drawing.
