Any way for Vol. calcualtions to be shown in Acre Feet? I am doing Volums of lakes and the client needs a report of the number of Acre Feet in the lake. To get the data, he uses a depth finder hooked up to a GPS. I can do this by hand calculator but using Civil 3D 2013 would be much easier.
View 9 RepliesI have my original surface I created with my point file and break lines. I created a new surface and was able to determine how to create my grading at a 3:1 slope that stopped at the surface I created from the point files. From there I went back to my Grading Groups and selected the Automatic Surface Creation.
From there I don’t know if I have to selected the Volume Base Surface and selected the surface I am grating from or if I can simply create a volume tin surface selecting the new surface and the original point surface for comparison. How do I make sure the Volume I am getting include the volume from the grading slope?
I have been asked to do volume calculations using Civil 3D for some concrete piles for a oil/survey company. I have done volume calculations for site and land development projects but nothing to do with concrete piles before. It also appears I am the only person with any Civil 3D back ground in the office. I did mention my experience with Civil 3D was limited but I was trying to expand it by looking for Civil 3D jobs and working through the 2012 Mastering AutoCAD Civil 3D book.
I am assuming doing volume calculations for concrete piles is quite different from doing volume calculations for grading plans. The company has been primary using AutoCAD Maps and doesn't have much set up for AutoCAD Civil 3D yet.
I must monthly calculate quantities. So i have 3 surfaces, one is representing the original ground level and the other two the measurements on the end of the months. Between the measurements I calculated volume. But I want calculate the quantities what is inside of the original ground level, what is outside that I want to exclude from the calculations. There is a way how to crop that surfaces to match with the original ground level?
View 9 Replies View RelatedI have learned the hard way that Civil 3D has a Curve Tolerance value that is to be used when applying sample lines and computing average end cross section volume calculations along an alignment with a curve. How I discovered this was by double checking my self and using a straight alignment verses an alignment with a curve. When using the alignment with a curve the average end cross section volumes differ. I did some reading in Autocad help and it mentions that sometimes a curve tolerance value is needed when using curves and this value is changed in the compute or edit materials window. What is a curve tolerance?" The edit materials window prompts a user to enter a Degree value. How do I calculate this curve tolerance value? I assume it is related to one of the values of a curve.

I 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.

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.

View 1 Replies View RelatedI can't seem to confirm the discharge table that hydraflow produces in hydraflow hydragraphs. I think I understand the equation itself (it's been a while since I took hydraulics), but can't understand where I'm making my error (if I am). Normally I trust the stage/discharge curve that hydraflow produces, but the City Engineer is asking me to confirm the values by hand and show them on the plans. Is there a link to an detention pond example that shows how a curve (the outflow values) was generated (confirms the discharge table at various elevations)? The equation is on page 85 of the users manual.
View 1 Replies View RelatedI built a containment dike using the grading functions in Autocad Civil 3D. I set up the feature lines at the top toes of the embankment and graded nicely down to the original dtm. I want to use user defined contour to get the interior storage from the original dtm up to a selected elevation within the containment dike. The containment dike forms an enclosed area. I know I could use infill and add a false bottom to the embankment surface (triangulation from bottom toe of embankment across to opposite embankment) but I want to check storage from original ground dtm.
Is there a workaround method to do this without creating infill? I know I need to get down to two surfaces to get a calculation.

View 5 Replies View RelatedI have a very simple surface. All of the elevations defining it, are set in feet. When I click on the surface it tells me my max and min elevations are in feet matching the points that I have defining the surface.
Here is the kicker, when I run a distance it is measuring the Z distance in inches and not feet. As you can see by the attached image the distance is 95' but the elevation change is 1 3/8". The actual points defining the surface are 1.28' difference. If I were to do a spot elevation on the surface, it would give me the correct elevation in feet. I am guessing that this is some sort of variable that I have missed, but damned if I can find it.
I am trying to get the feet mark (') on the dimension, right now I have 66.71 and I want 66.71'.

Second part, if the drawing is in metric do I open the Autocad Civil 3D metric icon or does it matter. Where I can read up on why there is a metic and imperial Autocad icon?

View 3 Replies View RelatedI have an alignment and have station labels. The alignment is labeled with "Major Stations" at every 100 feet. I need to change the station increment to 25 feet and have labels. I have done this although station 1+25 is still reading 1, station 1+50 is reading 1, etc. There is a precision variable somewhere, and I can't figure it out. I have played with the alignment labels style but no luck. Is there a global drawing settings somewhere that might be controlling this?
