AutoCAD Civil 3D :: Create 3D Object That Gives Volume Info?
Feb 22, 2012
I created an enclosed "object" adding break lines to two different surfaces.
The blue surface shown on the attached drawing is a set of break lines added to "Surface A" and then the red is the other set of break lines added to "Surface B". I have already generated the volume enclosed within the surfaces by doing a surface to surface volume calculation.
My Question:I want to combine the enclosed volume created by Surface A & Surface B into a 3D "Block" that give me the volume information.

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.

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?

I create surface, then i create alignement of pipe, pipe profile and assembly of the trench.
Then i created a corridor of the trench. Now i can not found out the way how to calculate the volume of the excavation
for the trench. i think that i should create a surface from the corridor of trench.

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.

What I would like to do is create volume calculations from spot heights. All i have is 4 rectangles with a 10m interval, nine elevations, no points or anything else.
What steps do i have to go through to make this possible?

I am trying to create a table that will incorporate info from structures and pipes. In C3d 2010 I want to make a CB chart which will show the pipe size, starting structure and invert. I would also like to include the CB rim elevation but that would be under the structure table. Is there any way I can combine the RIm elevation with the pipe table?

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.

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.

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.

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.

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?

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.

I have an alignment that I want to create a pipe network from using the "Create pipe network from object" command. I am able to create the pipe network, but it only places a structure at the beginning of the alignment. How do I get it to create structures at all of the vertices?

I use the create feature lines from object command from the Survey pull-down menu and choose a "Associate figure survey point to vertices" I get a survey figure that uses point elevations at some vertices and 0 at others. However, if I use Create Feature Lines from Objects under the Grading pull-down, and use a surface made of just the points, I get a a figure with all the correct elevations.
I checked the vertices where the survey figure drops to 0 and the line is snapped to the point, distance = 0.0000. What gives?

Is Autocad have a command to calculate the volume of a solid object? If so, it would come in handy at times.

Using C3d 2013. I am looking for a way to place the deflection angle of the PI of an Alignment in the label of a structure part that references said alignment. But PIs aren't an option when I select Reference Text type. Common sense tells me it would be under Alignments, but none of the PI data is an option of the Contents' Text Component Editor. I couldn't find it under any of the other Reference Text types either. I can pull the station value from the referenced alignment, is there a way to get it to tell me the deflection angle at the PI it sits on? Or even the difference in the instantaneous direction just before and just after the part?
I know listing the deflection angle of a PI is possible, as I have seen it in several examples of labeling alignments. I just want to place it in the label of other objects.who can tell me how to display LT (to represent left) and RT (to represent right) when the deflection is positive or negative respectively.

Any way to create a parcel from an object (closed polyline) and populate the parcel with Object Data from the polyline?
I have imported a .shp file into a drawing and the result is many closed polylines with properties similar to the attached image. I would like to bring this data into a parcel object for labeling purposes.

I can use SolidSelection.Item for 3D object's handles and but I can't take 3D object's volumes with SolidSelection.
Then I can put object 's handles(1EE) to a collection. Can I use SolidSelection to keep my 3D volumes values? All sub-structure of my program works with SolidSelection Object.
Volume Codes;
For Each tEnt In ThisDrawing.ModelSpace
If TypeOf tEnt Is Acad3DSolid Then
Dim tEntSolid As Acad3DSolid
Set tEntSolid = tEnt
tmpVols1.Add (tEntSolid.Handle & "/" & tEntSolid.Volume)
End If
Next
I can't match with returned result of these codes and SolidSelection.item(i)
For Each tEnt In ThisDrawing.ModelSpace
If TypeOf tEnt Is Acad3DSolid Then
Dim tEntSolid As Acad3DSolid
Set tEntSolid = tEnt
tmpVols1.Add (tEntSolid.Handle & "/" & tEntSolid.Volume)
[code]......

I am working on creating an alignment from a single polyline. The polyline, which was originally created in Carlson 2012, is a flat polyline that is about 1200 feet in length. When I select it with create alignment from object, it accepts it and seems to work. For some reason though, the stationing is way off --- e.g. the true 50' mark is showing up as 0+04.17 which results in an end station of 0+99.31 on a 1191' polyline.
edit> I also have tried this with a brand new polyline I created in civil3d, same issue.

I have 200,000 lines with some object data. LINKED to these lines is a database with some more information. Basically I want to export all of these lines to shape files, converting the information in the linked database to be the new object data. (This is for the client to view the lines on ArcGIS).
I have done this a few times in the past, but working with this volume of lines and data, Its taking an extremely long time.
My question is, could i use autolisp to quickly transfer the database data to object data before i export to shape files? or if there are any other options.

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.

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?

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.

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?
