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 RepliesI am working on a project, I was given a file with the contour already mapped out. I am tasked with finding volume of a fill I had to create. I made a 3-D polyline at the elevation I want my fill to start from and going down to my final grade. How can I make surfaces with my map. I do not have any files to make the surface off of. What is the easiest way I can make a layer, TIN has already been done but no surfaces are in the file.
View 2 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I try to calculate the quantities in the volume dashboard using a volume surface, I get the error that the surface is out of date. Is there a way to calculate volumes with an out of date surface?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.
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'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 8 Replies View RelatedOur company, was contracted to create a DTM of a residential neighborhood using our Lieca HDS C10 Laser Scanner. Utilizing the Leica software I was provided LandXML file that contained a 2ft by 2ft Mesh surface along with breaklines for the edge of roadway, driveways and sidewalks, which was imported into Civil 3D 2012.
Our client now wishes for us to provide them with a breakline for the crown of the roadway. My first thoughts on calculating such breakline was to set the Contours at an interval of 0.05' to identify the crown of the road, then drawn the break line along the crown based on contours.
Is there a way to automatically create a Breakline from Exisitng Surfaces?

View 3 Replies View RelatedI want to know if it is possible to calculate the water displacement volume of an assembly if it were immersed in water.
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.
I need to create an assembly that will give me the volume of a new shoulder along an existing road, as show in this picture.
I can easily make an alignment along my edge of pavement, and match the existing elevations, but I need to hold the cross slope constant AND the shoulder slope constant, and have the bottom of the shoulder slope to a target 2 feet off of my ROW.
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.
I have two cubes in two different layers so that one is red and one is blue. I want to attach these two cubes together at a surface, but keep that interface between them in the rendering (not just have them combine to form a continuous object with no interfaces).

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.

View 7 Replies View RelatedI'm trying to create an all new existing surface over existing ground. I have a TIN surface of the EG, and I have drawn overlay splines that describe the new surface, but how to go about creating that design surface.
It is a compound surface, open on one end and closed all around on the other, somewhat like a half of a football stadium, but with an irregular upper edge because I am needing to figure out cuts and fills to manipulate the EG into this new surface without costly major terraforming. There is about 40-50' vertical elevation between the "field" and the upper rim with a generally constant 7-10 deg. slope all around. I'm just at a loss to figure out how to approach this project, and am quite new to Civil 3D.

Any quick way of calculating average Parcel Area? I used to export to LandXML and do an area report in CSV. That doesn't seem to be working for me when I export out of C3D 2012.
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.
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.
Some background: We have a composite surface of existing surveyed contours as a TIN pasted into existing aerial contours that we received from a client. We used polylines to generate our proposed contours, and then generated a proposed surface from that. We've made a blank surface, pasted in the existing surface, and are trying to paste in our proposed surface... only the existing contours outside of the proposed suface no longer line up correctly once we do.
We've tried applying the method laid out here: [URL] ........ (and the link referenced in the bottom) but are still having trouble getting the surface to work. We've tried offsetting as little as 0.25' and as much as 5' with the feature line draped over the existing surface, but it seemed that the greater the offset, the greater the discrepancy.
Just to make sure we even tried that correctly - should the breaklines that we add be standard or non-destructive? (I've tried it both ways with little success either way, so I don't know if it matters much in this instance, but perhaps for future reference it would work.)
I've attached a screen shot of our surfaces. The pink and green lines are the proposed contours, the white dashed are the existing. The outer red line is offset 0.25'. As I've mentioned, we've tried offsetting various amounts with decreasing success.
I am having a problem with my data shortcuts for my surfaces not updating. I have 2 surfaces (one ex and one prop) both are on auto-rebuild. Both of them are in separate files and data short cutted into my profiles files (I have one for water, one sewer and a third for storm drains). Any time I make a change whether I add or subtract data the file the data does not update in the profiles. As a work around I have been creating a new data short cut and adding it to my profiles files. What am I doing wrong that would make them not update?
