AutoCAD Civil 3D :: Create Volume Surface To Show Elevation Banding With Cut And Fill Ranges

Nov 12, 2013

I am working on a large park project.  I have a proposed and existing surface.  I have created a volume surface to show elevation banding with cut and fill ranges.  I need to create a drawing for someone who doesn't have civil 3d showing all the "cut" areas.  They really want a boundary of hatch.  What is the best way to do this after I change my analysis to -30 feet cut to 0 feet cut.

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 :: Volume Bounded By Existing Surface And Design Surface

Dec 10, 2012

My goal is coming up with the volume bounded by the design surface and the existing surface. I don't have the design surface modeled yet.

Do i need to create alignment offsets?. Alignment 1 profile view is also attached. Then Alignment2.

What about starting with alignment1 profile view? Since I have created a polyline as the design profile ?

how do I shrink labels? Where is it in the settings ; the Align folder had been check.

AutoCAD Civil 3D :: Get Volume Elevation Table Masking To Work?

Dec 12, 2007

How to get the Volume Elevation Table masking to work?

I can only get the Title to work correctly - everything else plots as a black blob if Fill is on. With Fill off - there is no mask.

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 :: 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 :: Surface Volume Analysis

Jan 3, 2014

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.

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 :: TIN Volume Surface Shading?

Feb 10, 2012

I have a tin volume surface comprised of proposed and existing models for a large earthwork site. I would like a detailed cut fill diagram for presentation to project owner. The site involves cuts and fills up to 30' depths. I would like to be able to represent not only cuts and fills, but give a visual representation of the depth of cuts/fills (ie darker blues and reds in the deeper areas, lighter in the shallow areas). Is there a simple way to do this without setting up 100 different colors of blues and reds in the volume surface properties analysis tab? I have seen contractor software that performs this function rather easily.

AutoCAD Civil 3D :: Surface Volume Is Wrong

Apr 22, 2012

1) when I try to find volume of a cube 1*1*1

c3d volume report is 0.03 c.meter why?

First I make surface1 and import the 4 point with elevation 0 sec. I make surface 2 and import 4 point with elevation 1 then itry to find volume of this cube and my result is 0.03 c.meter why this happen. 

2) if this above method is wrong give me step by step guide of surface and volume.

3) how to find volume at particular level.?

AutoCAD Civil 3D :: Carriageway Surface Volume

Sep 10, 2013

I am trying to determine the volume of material (cut/fill) for a roadway surface in C3D 2013 using the volume dashboard.

I have created a fictional surface, basic profile and assembly so I can compare my calcs with C3D. After creating my surfaces and running the dashboard calcs, the program calculated the correct cut/fill volume. However looking at the surface in iso, I saw that additional surfaces were produced around zero elevation - refer to attached snapshot

In my actual model, I am well above zero elevation but these additional surfaces could cause problems on other projects.

AutoCAD Civil 3D :: Editing Surface By Volume

Jun 12, 2013

I have a pumped storage project where I would like to know the water level if a volume of water is removed. Is there an easier way to do this? Currently I have my drawing set up with my base surface and various top water level surfaces. I have been creating volume surfaces for each TWL and populating a spreadhseet that indicates how volume and surface area differs with TWL. It would be incredibly handy to work this in reverse ie ask the volume surface to lose or gain a required volume of water and update the TWL accordingly.

AutoCAD Civil 3D :: Export Surface Volume Tables?

Mar 7, 2012

I'm working in Civil3D 2011.  How to export the data from the surface volume tables to excel, or any other format outside of Civil3D?  

Or maybe a better question: how to create a stage storage table automatically within Civil3D?  The elevations table gives volumes per elevation class, but I'm trying to get cumulative volume stored below various elevations in my reservoir.

AutoCAD Civil 3D :: TIN Surface At Zero Elevation

May 22, 2013

I used the Volume dashboard to cal volume so when I view the surface in object viewer or 3D I see my TIN volumes surface at zero elevation is this right? I think the reason is because they want us to see both surface so they are not on top of one to another.

AutoCAD Civil 3D :: Possible To Create A Specific Contour In Volume Surface

Mar 2, 2012

I created surfaces in Civil 3d 2011 for existing and proposed and I did a surface volume between them. Is it possible to create a specific contour in the volume surface that represents the fill volume elevation (daylight line I think)? My proposed surface is a flood water elevation and I need to define the boundary at that elevation.

AutoCAD Civil 3D :: Project Object To Surface / Volume Calcs

Jul 30, 2013

see attachment (object viewer capture). The top surface is my OG, the bottom surface is the bottom of excavation for a building. I want to project the perimeter of the building footprint up to the OG surface at a 1:5 slope. I remember in LDD the perimeter of a building, berm, dam, ditch...could be projected to the OG with specific slopes and then you could create a surface with the projected lines and do a volume calc. between the two. What is the procedure to do this in AutoCAD Civil 3D 2012?

AutoCAD Civil 3D :: Surface Elevation Labels

Jun 26, 2013

I have a drawing that someone else created that has a spot elevation label for a surface. It labels the surface (PAD) then automatically subtracts a set distance for another elevation (GFE) and adds a set distance for another elevation (FFE). After doing some research, it looks like it was created with an expression?

I have two questions:

First, where to go to get a better understadning of this? I'm not familiar with expressions.

Second, where can I find the expression in drawing to make an edit to the set distances. I can remove the GFE/FFE as they are separate components in the label style, but I don't see where to modify the distance it adds or subtracts.
