AutoCAD Civil 3D :: Do Infills (grading) Not Display Cut Of Fill Styles
Feb 24, 2012Why would my infills (in one particular drawing) not display the diamond center-marker? I assume the infills are there as when I click to infill the area it highlights and the surface get created. I have no center marker therefore no way to apply a grading style or even look at the grading in the object viewer.

Dec 24, 2013"An infill grading has no criteria applied to it. Any area bounded by feature lines or lot lines that is not already a grading can be converted to an infill grading."
So given an area enclosed by a feature line, an infill grading can be created. Using the same features line, an feature line grading can also be created. what is the difference between these two surfaces? They both have no criteria applied to them.
AutoCAD Civil 3D :: How To Raise Grading
May 9, 2012Is there an easy way to raise an entire site by 1.0 foot and have the grading hit the previous targeted surface? The only way I have found is to grab all the feature lines and raise them up by the required amount, but by doing that, the grading bogs down my system and it crashes, plus, I have grading attached to 3dpoly's and not necessarily all feature lines.

Apr 25, 2013I am drawing a pond levy. I draw the outline of the top of the fill, set that at the elevation I want, then grade it down to the existing surface on a 6:1. The grading works perfectly. The outline of the fill's footprint shows up just fine around the back of the fill, but the toe line doesn't show up all along the front side of the fill, but I still get the slope lines projecting down in the front.

AutoCAD Civil 3D :: Grading Subdivisions
Oct 16, 2013I am working with Civil 3D 2014, I played with 2009 back in 2008 and before that it was Land desktop. I don't know if I am not following a standard workflow.
Build the EG from contours.Layout the CL for the ROW and convert to a horizontal alignments.Create the profiles.Design the vertical alignment in the profile.Create the assemblies for the different types of road sections.Full profile, pavement width assembly, the curb return assembly, the daylight left / right, 1/2 side left / right, and pavement width left / right.Build the corridor, set the target surface as EG or FG, depending on where the section of the corridor is located. (At the edge of the property to EG, then after the first building pad to FG)This is where I have a thought something is wrong. If I am grading the entire site, why would I have the ROW grade to the EG, when I will need the surface to grade from the ROW to the closest building pads?Create the intersections, using the different types of assemblies, per the ROW sections.Create feature lines and use elevation editor to set all the elevations around the pad.Using the Grading creation tool, grade to surface, using a 2:1 side slope. Then adding an infill to the pad.
I keep having the file crash after grading about 10 lots. I recover and it works find, but then the file runs very slow, and will crash. I haven't taken any classes in Civil 3d, and am looking for one in my area.
I am use to creating the vertical surface then creating points along the CL, TBC, FL, BOW then creating break lines along the points. Then create a break line for the pads, and build the FG contours from these break lines.
AutoCAD Civil 3D :: Grading From The Side
Aug 8, 2012Say I have a grading that runs north south and goes down 2%, up 2% and so on waffling along. Is it a poor practice to trace the side edge of the grading (in the same site) to add another grading to pitch east west?

AutoCAD Civil 3D :: Grading Against A Retaining Wall
Sep 8, 2012I have a platform at level 13.275m and nearby there is a retaining wall at aprox. level 4.0m.
For the wall i've made a surface using feature lines from EG till level 15.0m and then pasted into the EG surface to create the 'barrier' for the slope. But when i do the grading with the fill slope projection to surface, when it reaches the retaining wall section, the contour lines go crazy and if i do a quick profile, the fill slope line (obvious) is iregular, rather than a straight down line (2:1) going from level 13.275m till it hits the EG.
I've attached a picture to show the problem better.
AutoCAD Civil 3D :: Complex Object Grading
May 21, 2012I am tring to grade a complex object. Please see the attached document. The two grading objects are not interfacing correctly when graded although i can get the surface almost correct i beleive. Is there a way to remove this issue or the grading will not create a lot of difference when computing the volume clacs ( we are talking volum computation roughly about a million cubic metres cutting).

Aug 29, 2012I 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.

Apr 24, 2013I have a compost pad and retention pond to design, I set my back Pad line to surface and then graded to elevation so the slope to the pond will have no cuts
I created a pond and left out the grading to surface on the up hill side towards the pad which will be paved one day. I now created two side feature lines to enclose the whole pad and graded by distance and slope.
My problem now is the two side and back seem to blend together as I attached the feature lines together but I can not figure out how to blend into the pond create as it has side slopes to EG and the front which must join to the side slope crest to enclose the pad to drain into the pond.

AutoCAD Civil 3D :: Surface From Grading Objects
Jun 20, 2013It has been too long since I created Grading Objects and Proposed Surfaces. I am working in a file with my existing surface DATA Linked. I am creating a grading plan. I have created three separate grading objects in the Site named Proposed. One in the building, One is a new ditch, one is a graded existing ditch. I need to make these three with the unaffected areas of the existing surface into a new surface. How do I accomplish that . All my grading objects appear to be individually accurate and are created with a Feature Line and Grade to Surface Styles.

AutoCAD Civil 3D :: Volumes / Grading And Surfaces
May 30, 2012I 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.
AutoCAD Civil 3D :: Grading Object Projection
Jun 18, 2012I am having difficulty projecting an existing feature line at a specified tie-in slope. I have a steep (3:1) feature line that I need to project at a specific slope (2.5:1)to intersect a surface model. When I create the grading object the generated grading object is not 3:1 along the feature line and 2.5:1 perpendicular to the feature line. Instead I am left with a new slope that is 1.9:1 between the generated contours. I have attempted slope to surface as well as slope for a distance.My design criteria is to not exceed a 2.5:1 tie-in slope.

Feb 27, 2013I have this problem with EG covering over the cut area.
The feature line is partially under the surface making a cut.
It should be a hole where EG and the slopes meet as the image shows!
When I make an infill for the fill area it makes the the bottom of the cut area but the surface stays as a top!
It is very clear in Object viewer!
AutoCAD Civil 3D :: Grading Object Stability?
Mar 20, 2012Has the grading objects become anymore stable than they are in '09? Unfortunately, our company hasn't been able to upgrade to a newer version and we are beginning to get to the point where 'hand grading' everything is taking too long. I am proficient in using the grading tools, but everytime I do, my drawing becomes corrupt. I want to push us to the newer versions if at all possible.

Oct 3, 2013I'm currently trying to model all siteworks for a project using Civil 3D 2014. I created several grading groups that represent the various pads I need for the general project layout. Since this was the way I knew how to model the pads, now I have some intersections on the slopes between one grading group and the other. I was wondering if I could "merge" the grading groups in order for them to be just one big pad, that maintains all the levels from the other pads. Here is an image of what I am trying to explain:
What I want to do is to merge the regions circled in red, so that I have only one building pad on my terrain.
AutoCAD Civil 3D :: Grading Search Order
Apr 30, 2013I am needing to grade out from a featureline that is in cut to daylight in the fill direction (drainage flows away from the featureline). To do this I have created a grading critieria that has the Fill First Search Order parameter locked. I have verified that there is a fill solution if I use a 0.2% slope on the grading. Yet when I apply the grading it always uses the cut solution. It refuses to find a fill solution even if I apply 0.05% slope to the grading.

AutoCAD Civil 3D :: Volume Calculations With Grading
Dec 30, 2013I 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?
