I've been learning civil3d for some time now and I really want to understand how the program calculates volumes from road corridors.
When the top code is used to create surface from a road corridor, the created surface coincides with the top of the road pavement (binder/wearing course), which is not part of earthworks.
How can I create a surface at the formation level so as to compute actual earthworks?
I have create my surfaces and now need a volume between to two surfaces. I created the surface by using the Surface/Create TIN Surface tool for both my OG and the surface after material has been imported. I have gone to the volume dashboard and it will not let me add existing surface. How do I calculate the volume?
View 3 Replies View RelatedI have created surfaces for my original ground and my corridor. Both have appropriate boundaryies and the TIN looks good for both. I am trying to create a volume report through Volume Dashboard. I am able to create the volume surface with no issues but the numbers it comes up with do not seem correct. I can see from my profile that there is a small fill but the software seems to create a fill that is almost half of all the material when my profile shows there is more cut.
I tried creating a sample line group...it also shows the majority is cut. The only thing I can think is that there are about a dozen areas where my daylight does not work. how to do this volume correctly?
I am trying to get a material volume report for a corridor structure. The overall dirt cut fill is working, but the pavement and base keeps showing up as zero.
I started with the surfaces made, (perhaps that’s the problem,) I made an alignment, used an assembly, made a profile, and sample lines, made the corridor. The assembly draws in the cross sections, but the materials report shows zero in the pavement and stone.
I am currently still using AutoCAD version 2006. I have two lines with different Z coordinates. Is there a way to calculate volume in a basin?

In other words, I want to create a file in which ALL hollow spaces inside structural members, valves, pipework etc are assumed to be solid so that when that assembly is dropped in water, the total volume of water being displaced will be equal to the iProperty value for volume. I know its possible to hole patch when creating a shrinkwrap, but this is only effective for 'circular' hollow spaces and does not fill obscure or rectangular shaped empty volumes.
Is there a way to generate a volume report for a bounded volume surface?
View 3 Replies View RelatedI'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.
I've read a few threads on this way back but cannot locate them. I have two surfaces and create a volume surface and it reported the volume as 493 cy. I then ran some sample lines at 25 foot interval and the total volume is reported as 964 cy.
View 1 Replies View RelatedI 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?
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.

Even all the properties of the corridor setup from one to another would be useful. I'm building one corridor and an 2nd one that matches everything except I need to replace my Assembly with one meant for stripping.
My corridor surface is not matching my corridor top links. see attachments. this is affecting my volumes!
The section-plan(surface red).png is showing the section editor and the plan view. the red highlighted line in section is the corridor surface and as you can see in plan view the surface is incorrect and wiggly.
The pdf is all my sections with the red linework being the corridor surface.

My background is actually in Microstation (mainly 2D). I was asked if I could calculate the cut and fill between two topo surfaces. Unfortunately, I don't have the files yet but I will eventually receive them. When I do, what would be the correct method to achieve this task?
View 3 Replies View RelatedWe have a good size channel and the section for the channel varies quite a bit. We want to find the volume excavated in the channel between 2 elevations (it is the area of sand per the goetech report)? A template was not used to create the channel surface, breaklines and gradings were used.

The workaround I found was to select all the parcels in Prospector, copy to clip board, paste in excel, find and replace "_Sq. Ft._" with 0, then do the average.
I am looking to calculate the volume of an existing berm from a TIN surface. I have read through some of the Civil 3D tutorials, and realize that I will need to have two surfaces (base and comparison), but need to figure out how to create the comparison surface.
View 9 Replies View RelatedI have been provided a file with a surface, however I have not been provided with the point files referenced to define the surface. As a result, when I try to calculate the quantities in the volume dashboard using a volume surface, I get the error that the surface is out of date. Is there a way to calculate volumes with an out of date surface?
I am trying to calculate the amount of material required to be cut when creating a flat bottom ditch.
In Land Desktop using the Hydrology tools, we could get capacities for rectangular pipes based on slope, size, etc.
I have tried using the Hydraflow Express tools for this, but cannot figure out how to use them for a RECTANGULAR pipe (i.e. 10x4) box. Saw the circular option, but couldn't change where it says circular.
This is not a culvert analysis because we have inlets, multiple slopes, etc. It is part of an entire system.
I use these tools to layout the system before I want to put it into the analyses software we are using.
I notice issues using spanning pipe labels for the first time recently after having used them for years. The slope calculated by the spanning pipe label is completely wrong. I've attached a picture in which Labeled two pipes connected by a null structure. The two labels on the bottom are the pipes labeled individually at 3.53% and 3.34%. When labeling them as a spanning pipe, if I choose the downstream pipe first and them the upstream pipe it shows me a slope of 0.48%. If I choose the upstream pipe first, then it gives me 2.88%. Either way it's wrong.
As I was writing this I decided to check and see if the pipes were flowing the same direction (Start to End or End to Start). Turns out they weren't. After flipping one of the pipes around so that they both are laid out in the same direction (Start to End from Upstream to Downstream) the label now reads 3.37%, which is correct.
Seems like an the label should honor the flow direction of the pipe, no matter if they have been laid out in opposite directions or not.
We are looking for a workflow example of developing casting models into machining models.
Typically our castings are made from different materials (Fig-1) and then machining (Fig-2) are created from these castings.
Is creating the casting as an iPart (with different materials) and then deriving the machining from the casting the proper method?
Doing it this way seems to force us into making a machining for each casting material instead of just one machining that is an iPart. How should this be set-up for BOM purposes and for use with Vault (Base Version)?
I have the task of creating elevation views of a site. These views require that the model be clipped along a section line to crop the forground so it doesn't obstruct the view of the site.
I've experimented with the section plane tools in the 3D modeling workspace but I can't get a section view. I suspect it is because they don't work with C3D surface objects. Any workflow for this task? Ultimately I need to generate hard copies of the views for the architect to use for his landscape plans.
Infrastructure Modeler is a handy tool for creating nice 3D models for presentation. But how can we distribute these models for stake holders to review? Sure we can create nice video presentations but we want them to be able to nagivate the model freely. Is there any way to get the models into 3D PDF format?
The same issue arises with Civil 3D. Apparently it does not support output to 3D PDF. Do we have to purchase a driver for this?

View 4 Replies View Relatedi'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. question...how 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.
View 4 Replies View RelatedI 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?
I am using C3D 13 and have created a surface using points that were shot on a 50' grid. Now I am looking for the easy button to get a volume.
View 3 Replies View RelatedI'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.
I am using C3D 2012 and i know how to create a table showing volumes for different elevation ranges with different colours, but how to show the total cut or fill for the volume surface in the same table so that you dont have to manually add up all of the cuts or fills? or have to display only two ranges?
