I'm working on a project to widen a roadway through some mountains. The problem i am having is getting the corridor to apply to a future surface so that i can determine the volume difference. my profiles show there should be some cut and fill, but i cannot get the model to reflect this. when i try to preform a bounded volume i recieve a "the surfaces do not overlap".
View 3 RepliesI have sevreal corridors with various spurs. The contractor wants the cut/fill volume in sections along the corridors, not one big cut/fill calc. Is there a way to do this in C3D? I have got the volume table with the chainages on, but he does not want a cumulitive figure for the whole corridor.

View 3 Replies View RelatedI'm working on a windfarm access road with tight bends that need to be 2.5m wider than the straights. I have created offset alignents and the corridor with no problem but how can I label the widths to show the variation in width at the various locations. The road is at the full width (7.5m) between tangent points and then tapers to the standard width of 5m
I have shown simple aligned dimensions on the screenshot but I'm sure there will be a way to do this automatically - won't there?

I use SAC 2014 to create a subassembly such as following but when design, the next Subassembly doesn’t attach with point P4, while the terms verify as designed is TRUE.
I checked and found that the Layout mode is different with- the Roadway mode.
attached is Roadway.dwg file
I made "Road" surface from Corridor Properties / Surfaces... but when I go to surface properties for "Road"...the statistics tab is blank.

Is there a way to design the road profile to use the low point at a certain Roadway station so you can put your storm inlets to line up with property lines. Because when you create a Sag the PVI is not where your low point falls on the profile. It would be nice to be able to drag the low point not the PVI to create the low point where you need it instead of a sort of back and forth dragging the PVI of the vertical curve.
View 9 Replies View RelatedI currently work for a construction company, we mostly focus on roadway rehabilitaion. We recieve DOT paper plans containing the construction plans and cross sections. I have been till now using the cross sections to build the roadway in Agtek, which is the software we use, then from there I can do my takeoff for excavation, utlites and areas. We have the 2012 BIM software and i'm very intersted in using that to rebuild the plans so I can preform the takeoff just as the DOT does as well as to model the utilities. Also i'm intersted in creating the model to show the estimators and the higher ups, so we can create a phasing plans, traffic plans or how we would want to handle the roadway rehab in general. I'm a novice in terms of Civil 3D, so this would be something i'd be practicing at home first.

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.

I have a question concernig a wrong result of computed volume.
EG surface with all EG points H=100.00m
FG surfase, created by FL-Square 100x100m H=101.00m, added to FG surface as breakline.
The Result-Fill=9149.59???
Why not 100x100x1=10 000???
P.S. EG points at above example were around 80, randomly spread at area say 150x150m
When I deleted 76 and moved remainig 4 at the corners of the square, the result is OK 10 000cu.m
I am trying to find an easy way of calculating the volumes I have been asked to do. I have a road, with an alignment created along the centreline. I have created a finished surface which incorporates the cutout for the boxing, and I have been supplied with a surface of the natural (original state) ground.
What I have been asked to do is calculate volumes at either 10m or 20m chainages (station).
Obviously, I can create a boundary, and then shift the boundary to where I want the volumes to be, but this road is 3km long, resulting in calculating 150-300 different volumes. The road is not a straight line either and includes a number of bends.
Is there a quick way of calculating this? Or do I need to use the boundary option?
The way they would normally calc it is to add all the details from the cross-sections into an excel sheet, and makesome complex formulas to figure it out. Even doing the boundary method is quicker than that.
We 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.
View 9 Replies View RelatedI have noticed that the value I get when I use the surface volume comparison tool or look at a graded item in the grading group properties box is different than if I calculate it by hand and the discrepancy isn't even consistant. After spotting this problem in a job I am working on graded two simple ponds to check this. The first one is 100' x 100' and 5' deep w/ 2:1 side slopes. Calculating the volume by hand I get 1500 cu. yds but the grading group properties come up to 1506.17 cu. yds. The accuracy is off by less than 0.5% The second pond is 100' x 100' and 2' deep with 3:1 side slopes. The hand calc gets me 654.52 cu. yds. and the grading group properties reads 655 cu. yds. This discrepancy is closer to 7%. I really need to know if I can trust the volume tools in the program.
View 9 Replies View RelatedI am attempting to take two surfaces and cut straight down through a set polyline and get the difference between two surfaces. Do i want to use the bounded volumes to do this? Or can i simply create two surfaces and and use the analyze/volumes tool and just select the two. I would then add the boundary to each surface to limit the data.
My concern is since the two surfaces do not meet along the edges which will cause the math to be off.
I have a few vary large stockpile that i need to get volumes of the stockpile at 1 meter intervals- is there a quick way of doing this, other then finding the area of each elevation and calculating the volumes.
View 8 Replies View RelatedI have an existing topo surface created as well as grading for a proposed elevated pad of earth done in civil 3d 2013. I simply want to calculate the cut and fill quantities. I created the grading with automatic surface creation checked on. When I use volume tools to see what the quantities are, it says 0.0 for both cut and fill.
I created another surface (TIN) and pasted the existing topo surface and the proposed grading surface into it and I couldn't get any quantities.
I created another surface (TIN volume) and set the base surface as the existing surface and the comparison surface as the surface created from the grading but again could get no quantities.
I am looking to find out if the is a way of generating a stage storage table or volume table showing only the volume in the pond from the lowest intersecting existing ground contour to the top of the pond (to determine what would spill out of the pond in case of a berm failure) and if Civil 3D could make the determination of where that intersecting point is.

It has 2.5:1 Side slopes and a 10 foot wide ramp at 10:1 entering the pond to the floor bottom. I am trying to figure out what the volume of this pond is. What is the fastest and most efficient way to get this volume? I do not want it compared to any other surface such as existing ground.
View 7 Replies View RelatedI have a big hole in the ground in my model. Its easy to get the volume of cut with C3D. But I have a topsoil layer, weathered rock layer and then solid rock, I basically need to break them down into different volumes. The way I would normally do it is calculate the topsoil, then work out the weathered rock and minus the topsoil, then for solid rock cut I minus the topsoil+weathered rock. I have attached the 3 volumes I need for info.
View 8 Replies View Relatedusing CIvil3D to figure volumes. I have a very large aerial topo from a couple years ago to compare against a topographical survey I completed this year. No problem creating surfaces.
Question: In the topo's, I need to get a volume from two different areas....one area being a fill area, the other being the borrow area. Don't want any volume data throughout the rest of the site.
Do I just create one large surface for each topo and designate boundaries somehow? Or do I need to create multiple surfaces for each topo? If this is the case, will I need to make sure any breaklines, etc. don't cross from one area to the other?
I have a 100 acre park that I am doing earthworks. I have 1 proposed and 1 existing surface. The park is now broke into 5 different areas and I need to get cut and fill for each area. Is there a way to do a volume report for a particular area? I could define the area with a polyline. Or do I need to copy the proposed surface and start chopping up into 5 areas?
View 9 Replies View RelatedI have created a volume surface and associated surface legend table using the cut/fill parameter.
The volumes and areas don't seem to add up, take Cut 2 as an example only if the area of the previous (cut 1) was added could this be possible. There is lots of speculation in our office like does the fill work in reverse?
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.

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.
Is there a way I can sort the columns in the dashboard alphabetically? Normally you just click the title in these windows to toggle the way it sorts it, but you cannot do that with this tool. Its making my cut/fill report look messy, as the surface volumes are not in any order.
View 2 Replies View RelatedI am trying to get the cut volumes for areas that are greater than 15ft of cut for my project. We know that we will be able to get the top 15 feet with heavy equipment but will be drilling and blasting anything greater than 15 feet of cut. This is a different pay item, with greater cost so we need to quantify it.
I've got a composite surface that graphically shows me the elevation bands so I can see the areas that are greater than 15 feet but I'm not sure how to quantify the volumes.
Currently using C3D 2012 with the volume dashboard extension. Have 2013 installed just haven't jumped over yet.
Whenever I open the Volumes Dashboard in a drawing and then close it, my cursor and my WCS compass start blinking erratically, and the program seems more apt to freeze up when I try to do other things from that point on, especially if I try to move to a drawing in another tab. If I bring back the volumes dashboard, it's fine again, but then I've got the annoying outlining of my volume surfaces that I don't want. how to handle this? Is it just an unavoidable glitch in the program?
