I use Civil 3D 2011 and I am new to it. I have created a natural ground surface from survey points. Now i want to create a finished surface with a specific slope in a specific direction at a specific elevation and then to calculate cut and fill volume.
I can create a flat surface at a specific elevation. How to tilt this surface to a specific slope along a specific direction.
How to calculate in a table the volume of cut and fill between the stations, The horizontal and vertical alignments are generated along with their sections. I’m wondering if there is a tool that summarize the volume of cut and fill between the stations in a table.

To calculate the volume ,I need to include this uneven rock surface wall.
For doing so,The sharp edge will displays in the cross section.
Because the uneven surface, I cannot create the surface with normal step.The TIn line will joins horizontally,not in vertical direction as is intended.

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.
View 3 Replies View RelatedHow to calculate the AREA of cut and fill analogous to the volume of cut and fill between surfaces, but instead only between the alignment and the road profile in the prolfile view. From what I've read of similar posts a few people have had the same question but have been instructed how to do it with volumes as opposed to area. Also how to insert a table of cut and fill area analogous to the one you can inset from the volumes dashboard.
View 5 Replies View RelatedI need write Cut and Fill Labels on Volume surface in each 10x10 meters. Civil 3D can write Spot Levels on grid, but I need write Cut
and Fill values in grid area. Using Surface >Utilities>Bounded volumes I can get the values on selected closed polygon, but write to all is very long work. How to do write Cut and Fill labels on grid.
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.
View 9 Replies View RelatedI followed the steps I found online to create color-specific surface labels (I assigned red to the cut elev and green for the fill elev.), but when I display them using the spot elevation on grid, I am getting both red and green elevations on same point (they are both fill elev or cut elev.), and why are there two elevations (cut-red and fill green) displaying?
View 9 Replies View RelatedWhat formula Civil3D uses to calculate the average slope of a surface?
The formula I am using is S = I*L/A
S = Average Slope
I = Contour Invertval
L = Length of Contours (ft)
A = Area of parcel (sq. ft)
I just had to do four parcel calcs and the percentage I find using the formula is always 1-3% lower than the percentage Civil3D spits out. I can't find anything about how Civil3D arrives at that number, it just appears. I assume that Civil3D is more accurate but I can't give that number to a client without knowing how the program arrived there.
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.

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 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?
in my link "link slope to surface", i have the slope set to -2.00%. in the cross sections, it is at a +2.00%. why is this thing not linking at the defined -2%? see image.
View 1 Replies View RelatedPlease find the attached picture. It shows a surface with its data points. I extended the surface to the outer boarder shown by kriging. The slope of the surface that was added with the extension (past the data points) has an upward slope that was generated. I need the surface to stay level with the data points that are there.
How to avoid that added slope when extending a surface?
I'm modeling a simple corridor (12' lane 2%, 6' shoulder 6%, 4:1 to match EG). I used the "LinkSlopeToSurface" subassembly for the 4:1 to match the EG. Unfortunately our EG isn't always wide enough for the 4:1 slope to match it somewhere.
Is there an assembly that would use 4:1 as a standard daylight slope, but where necessary adjust the slope, max. 3.5:1, to match EG surface?
I am using AutoCAD Civil 3D to do a slope analysis across project locations. When defining slope categories, I am finding that the max slope percentages are astronomically high; ranges are being returned up to 360,000%--and I've only done three regions! I understand vertical slope but these percentages are not realistic by any means, especially through the areas in which I am working.
A specific example: between a contour at elevation of 792 ft and a contour at elevation of 794 ft at a distance of approximately 60 feet, the slope percentage being returned is in the 9000% range. There is not a sudden drop or rapid change in elevation between these two contour intervals to provide reason for this high of a percentage. I would expect to have a slope percentage nearer the 3% range.
The data source of the contour information is LiDAR being brought into CAD via the task-based geospatial option using MapImport. All data tables are being kept. Polygons are being imported as closed polygons. There are no surface errors being reported upon creation. The project locations were created in another program and imported into CAD using the same manner. The only thing that I can conjure up is that there is some sort setting issue.
I have created a road for a pit mine (which is unlike roads I have designed in the past). The road switched back towards itself and I need to daylight the cut slopes to show the limits of the mine/road cut. However, my cut/fill lines are not showing up in my cross-sections, but the plan view is showing the limits of excavation.
I assume this is because my limits are intersecting, from each of the roads, the upper and the lower. How can I get around this, or why are my cross-section lines not showing?
I change my surface style to slope banding (3 ranges) and make a legend table.All of the three ranges in the table are red and my surface ranges are blue, yellow, & red.

View 8 Replies View RelatedI am trying to create grading slope from a Feature line that was created at a constant elevation of 609m. I want to create a slope of 3:1 from the feature line to a surface I created. I recall in AutoCAD Civil 3D 2011 that you could create a slope directly to a surface. Is there a way of doing that in 2014 or did I simply forget a step when I created my Grading Groups?
I created the grading group using the Grading Creation Tool Pallet and selecting Set Grading Group. Then I set my target surface to the one I want to grade towards. I thought all I had to do than was go to Create Grading select the direction of grading and the slope. I thought the slope would continue to the target surface but it asked for a distance for grade that would throw off any volumes I want to pull off.
Did I have to create a new surface for my Pad at 609m than grade from that and how would I make sure my slope continues till it contacting the surface I want to target?
Am I correct in assuming that if Surface Labels by One Point is chosen, the slope as shown is the maximum slope of the surface triangle where the point was chosen??

View 1 Replies View RelatedOn my corridor I am using Link Slope to Surface, using a 3:1 slope. But it is giving me a 3:1 slope radial to the corridor - what I really need is a 3:1 slope between the contours themselves. On the inside of a tight curve, this makes a big difference. See the attached screenshot. Is there a workaround for this?

View 3 Replies View RelatedI have created surfaces for my original ground and my corridor. Both have appropriate boundaryies and the TIN looks good for both. I am trying to create a volume report through Volume Dashboard. I am able to create the volume surface with no issues but the numbers it comes up with do not seem correct. I can see from my profile that there is a small fill but the software seems to create a fill that is almost half of all the material when my profile shows there is more cut.
I tried creating a sample line group...it also shows the majority is cut. The only thing I can think is that there are about a dozen areas where my daylight does not work. how to do this volume correctly?
