AutoCAD Civil 3D :: Volume Boundary Creates Incorrect Volume
Feb 25, 2013
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'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?
"The filename, directory name or volume label syntax is incorrect. The database in K;lah/blahlah.widget.ipt* could not be saved".It's nothing to do with an improper name; even saving as the default 'Part 3' doesn't work.
At the moment I'm limping by using Save Copy As. Neither Save not Save As work at all.
I'm no longer able to control the PP (monitor) volume using my computer volume controls. I've always controlled the monitor volume using my computer volume levels, but starting today, that has changed.
The volume is just playing at the level recorded with no way for me to turn down or up.I performed a disc repair and that didn't solve the problem.
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?
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?
Within my road corridor, I have one section where the excavated material cannot be used as fill elsewhere. I see a place where I can specify a factor for reusable volume when I compute earthwork materials. But it looks like I can only use 1 factor for the whole corridor. Is there a way to say from Sta XX+XX to Sta XX+XX the reusable fill factor is 0, but the rest of the project it is something else?
All I can think to do is copy the quantity report to Excel and manually change the reusable volume in that station range to 0. But, since the report comes in as just numbers (no formulas), I then have to enter all the formulas to recalculate the volumes.
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.
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.
I can see the area of a TIN surface no worries (under Surface Properties/Statistics/Extended), but want I want to get is surface area of a TIN volume surface where no "extended" option seems to be available to view the area information with this type of surface.
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.
volume dashboard on which method of calculating is based. Why sometime are different, huge differences between counting volume based in "computer materials" which of 3 is the best? for calculating? I am using very often average end area, is that correct?
I have 4 corridors on same alignments (pics1). I created materials for each corridors (pic2). Then I created multiple section view for each corridor (pic3) ( for all corridors in section view table tab, i added corridors own materials). but cumulative material volume reset to zero at each new corridors beginning. In my project, corridors cumulative material volume value should continue from the previous corridor's value. Can i connect this volume tables or can i merge corridors ?
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.
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.
I 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 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.
