AutoCAD Civil 3D :: Grading From Feature Lines
Aug 15, 2013I have a created a surface from contour lines.I have drawn a feature line and assigned elevations (it slopes down from 3.5m elevation to 2m elevation). I have added grading from the feature line to the existing surface but have not merged the feature line with the surface.
I also have to make a low area (elevation at 1.5m) on the surface and know i need to grade at 1:1 from the feature line to the low point. Is there a way to grade from a feature line at a given grade (1:1) to a known height (my low point at 1.5m) without drawing another feature line for my low point? Seeing as the height of the feature line varies I can't just offset it at the grade.. I.e. the grade is the constant here.
I will have a few walls and lower / higher areas to grade to. I have drawn the top of my wall and mounds and have assigned them elevations but not sure whether to now make them all feature lines and try to merge with the surface by grading at a set grade or to do some sort of infill.

Mar 19, 2013I have this problem when creating grading groups with more than one feature line in them. It seems really unstable when you trying get the grading to connect. I have tried to create two separate grading groups in one site or two feature lines in one grading group. And the result is the same, the grading that will be create can sometimes look oki, but suddenly they tend to disappear or look weird...

Oct 12, 2011I have been creating grading objects from my curb lines, assigning grades using the editor, then offsetting that line for the BACK of curb, and using the raise-lower command to raise the curb line height. If I edit the original face of curb line (gutter grade) then I go back and redo the process. Is there any way to intelligently link these two lines so that if one gets edited C3D knows the other is 0.5 feet higher (or lower) than its neighbor?

Jun 26, 2012When creating Feature Lines, I wanted them to be e.g. Step Line 1, Step Line 2, Step Line 3 etc so I amended the name template to suit. I created multiple from objects and the naming convention worked. If I did features individually (as I wanted certain ones in certain sites) it worked for the first feature but reverted back to the default Feature line name on subsequent entry to the dialog i.e. it had "forgotten" the template name just set.
Am I missing something to get this to work correctly or is this how it's supposed to work i.e. useless for individual feature line creation?? This also happens for gradings.

AutoCAD Civil 3D :: Section Labels From Surface Features Lines
Jun 27, 2012Often we build a design surface from feature lines and possibly a grading or two. Then we cut sections.
Now, for set out, and especially for smaller contractors who don't have fancy survey gear, it would be really nice to be able to show design surface levels in section bands BUT ONLY AT THE SURFACE-DEFINING FEATURE LINE LOCATIONS.
I am aware that we can use grade breaks...but this gives us band data at each triangle intercept which is too much data. We can weed this data, but that is indiscriminate and I really need only the data at the surface-defining geometry points (feature line locations.)
We can also use station/elevation labels on the section views but this is time-consuming and non-dynamic. Band labels are dynamic and more or less automatic...if only we could get the discrete locations we need labelled.
AutoCAD Civil 3D :: Infill Grading VS Feature Line Grading
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.

Nov 8, 2012Here is the issue we have found. While sectioning a view of an assembly in idw, the threaded lines of threaded features have a strange behavior depending on the section line used. I have attached a simple example that shows what he have found. Basically, if the section line is straight, threaded features show correctely. Independent of section participation. If the section has segments at different angles, then lines are not appearing.
The first three views have both parts excluded from section participation(Obviously, there isn't any real life need for this, but I did it to just simplify the illustration without adding a bunch extra parts) The base view is the top view or view showing the round shape. For the first example at the bottom, i simply projected the view to the left and made sure "Threaded Features" was selected. Threaded lines show fine.
Second example is the similiar, except the i used a section view instead of the projected view. Both parts are excluded. Section line is straight. Verticle in this example. Doesn't have to vertical as the line is straight.
Next example is similiar to the second, only difference is the section is not straight. You can see the threaded lines do not show. This is the problem we want to solve. How to make the threaded lines display!!!
Last example shows the same section, only this time the component is included in the section participation. And it works.
Any settings to change or a trick to make it work. Otherwise, i think i need to issue a support request with autodesk.

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.

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.

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!
