AutoCAD Civil 3D :: Mill And Overlay Parameters
Dec 19, 2013
I am trying to overlay a large area,I have a design profile grade that I must use. I need the new edge of the overlay pavement to be 2" above the existing as long as the pavement cross slope is between 1% to 1.5% . If the slope goes above or below the min or max I need it to take the min or max. If I use the overlaymillandlevel2 I am unable to get it to use the overlay thickness since i am using a profile.

I have a project where I am removing existing asphalt pavement and overlaying new pavement. I am changing the existing profile and cross-slope to tie-in to the existing profile and cross-slope. know of a mill and overlay subassembly that will allow you to tie the edge to a profile or feature line?

I'm looking to make an assembly to follow the crown of the existing roadway which is to be milled and overlayed. In addition to being milled and overlayed there will be a curb bumpout which will be full depth pavement. The roadway does not hold a constant crown at 2%, it varies which is why I would like it to mimic the existing roadway cross slope. What would be the best way to go about making an assembly to model this. I have attached an image so that you may get an idea of the situation. I have a curb gutter line which I would like the assembly to target in both width and elevation. The single slanted hatch is mill and overlay and the double slanted hatch is full depth pavement (widening).

C3D 2013. 64 bit. Windows 7.
Question 1.In C3D 2013 is there a ceiling to the number of points allowable in a C3D surface? Is it 1.5 million?
Question 2. In C3D 2013, when creating a surface from Point Cloud data is there a maximum point count based on the answer to question 1 - or is a different point count limit applied?

I've been trying to model cut produced by a ball end mill taking an arbitrary 3D path. I know how to do this for 2D paths (and this has been discussed a couple of times on this forum), but I have had little to no success extending this to paths in 3D. I've attached an Inventor file that demonstrates what I want to do, it has an sketch that describes the tip of the end mill and the path that I want the center of the tip to trace out.
This seems like something that should be possible using sweep feature, but if it is then I have not found a way to get this to work. The issue is that I have not been able to effectively control the angle of the sweep plane with respect to the path. In reality, the normal of the plane should be equal to the tangent of the path with the z-component zeroed out.
However, if I sweep using the path and the "Path orientation" then it does not zero out the z-component, if I sweep using the path and the "Parallel orientation" it does not take the x&y tangent components, if I sweep using a guide rail or guide surfaces it also does not zero out the z-component.
In fact, the only way I could come up with to accomplish this would be to sweep the path in 2D and then to use a series of bend part features in order to put things into 3D. So far as I can tell this works, but back calculating the 2D curve is so backwards and laborious that I can't imagine using this for anything. In Solidworks this is relatively easy using the sweep solid feature .

I am having a problem with an overlay and widening C3D 2012 project. The sub assembly I have chosen is processing with the corridor datum surface cutting into the existing road surface, as would happen with a “milling” section (which I don’t want), I need it to overlay onto the existing surface only, with a nominal minimum thickness of 4” . I think this sub assembly is drawing the datum surface from the datum point of the widening on one side to the datum point of the widening on the other side, not sampling the "bottom" of the overlay surface.
See attached screen shot. Also attached are screen shots for some of the sub assembly and corridor parameters for my current settings. I am using the “overlaywidenmatchslope1” and “basicsideslopecutditch” subassemblies.
I have tried changing the sample point offsets and the insert point offsets without fixing this problem. I have not added any additional alignments for saw-cutting yet as I am trying to keep it simple until I get the assembly to process correctly with a fixed width.
I looked at trying the “overlaywidenmatchslope2” subassembly, but it is for non-crowned roads and would not work for this project. Are some of my parameters wrong? Is there another subassembly that I should be using?

Would be interested in a strategy for a varying depth overlay, i.e. where the overlay assembly follows a centerline design profile rather than a pavement depth up from existing grade. Then the trick would be for the software to calculate the asphalt volume between the new top surface and the existing roadway surface.

I need to create a carriageway overlay corridor on and existing carriageway that has a curved surface and not a typical crossfall. I've tried the LaneParabolic assembly but it doesn't give me the control I need to target an alignment and profile.

I am overlaying and widening an existing road, however the assembly is not behaving as I would like it too. Here is the cross section below, the widening, overlay and day lighting portions appear correct, how the Datum surface is off.
DATUM SURFACE - The datum surface is not following the existing ground in between the two road widening pavement portions. You can see the datum surface as a red line connecting the two paved widening below the existing crown of the road. I would expect the datum surface to follow bottom links of the overlay as well up through the crown, but this is not the case.
EARTHWORKS CUT/FILL SURFACE - The earthworks surface shows that the area between the existing crown and the unexpected datum link is being calculated cut/fill (cut presumably) which it shouldn't be.
ASSEMBLY BEING USED: Perhaps I am misusing the subassemblies, or link codes need to be modified.

I'm very new to Civil 3D.I've been given original topography in a .dwg file and a .csv file of the same topography after some dirt work.My problem is when I import the .csv file the points don't overlay the original topography.
What I have done is added the .csv points to the original topography .dwg with the "Points From File" option.

I am currently using Civil 3D 2011 and 2012 but soon making the jump to 2013.In my project I want to able to present a 3D-object from Civil 3D 2011 to Navisworks, eg the body of a road. I am doing this currently with the add-on program from Autodesk Labs named Corridor Solids. The several different 3D-objects that represent the different layers of the road body needs to have a certain set of parameters. For instance, Name, Dimensions, Material and so forth.
Currently, the only thing that I can present in Navisworks is the layer name that I associate to that object when I export it from Civil 3D with Corridor Solids.Is there a way, in vanilla Civil 3D or perhaps an add-on program that I can use to associate more parameters to a solid?

Is there a way to change a RAW description such as EC12 +, or EC11 -, to say SWP12 +, SWP11 -
I'm not having much luck using the parameter settings. 1$
I tried Code = EC*, format=SWP1$
That didn't work... I got literally SWP1$ instead of SWP12 +
Is it a space thing? Do I have to rename all the descriptions to have a space before the parameter?
i.e. EC 12 +
I'm hoping this isn't the case and some form of wildcard can be use.

I am using one assembly for this project and of course the existing surface does not always work well with one assembly so I have been using the corridor section editor to adjust each station individually. Attached is a picture of my first station, I started with a 3:1 fore slope (left side) and have changed it to a 2:1 slope. However, my ditch line elevation did not adjust and my parameter editor will not let me adjust the beginning elevation for the ditch line. I am curious as to what the simple solution is for this so my ditchline and back slope or slope to surface will be portrayed correctly.

Is it possible to change the parameters of a subassembly - for example in an assembly comprising several subassemblies, can I change a parameter in Subassembly.LaneOutsideSuper, for example, to vary the Lane Width from 4m at CH90 to 3.25m at CH160m and keep it at 3.25m for the rest of the corridor.
I am new to Civil3D.

Im wondering if its possible to link either a constraint dimension to an action parameter or vice versa. Or using a linear parameter's value in an user parameter formula.
Its a 2D cylinder, for winding purposes we just have a rectangle, with a distance from the Y axis for radial.
Parametric dimensions: B=thickness, C=Lenght, R=radius
User parameter: A=Diameter (R*2), Mass in kg ((((pi*(c*b))*(A+B))*1.25)/1000)/1000
For the BOM, i need A, B, C & mass
For drawing references for peoples on the floor, to distinquish a cylinder from a stick, we put lines at the top and bottom of the cylinder, 1mm distance inbetween them.
I figured that making a linear parameter + stretch on the thickness to replace the B parametric dimension, allowed me to make an array of that line, with increments of 1mm as i stretch the cylinder. The thing is that the mass formula cant take the value of action parameters....
Other alternative is to keep the B parametric dimension, and add a linear parameter as above for the array. But then i have 2 places to adjust, and from a test i made, if i change the R dimension, the linear one does not follow. Its very frustrating.
What i was hoping autocad would be able to do is distance1 for array to be same as B dimension, but it does not allow me to do that, unless im missing something.

When i am creating a assembly, the sub assembly parameters for the generic pavement structure is not showing (such as the lane width or crossfall) Other sub-assemlies show these parameters. Is this a bug or is there a way i can turn this on.
I can change the parameters on the properties.

I am just having some difficulties using the standard UKIE subassemblies where the carriageway is not showing the parameters correct. See the drawing attached. Eg:
1) The properties does not show the side correctly it has a zero value (not much of a issue as i can use the mirror command) (drawing subassembly)
2) I am unable to choose any superelevation on the subassembly . Now this is what causing me problems.
I have already re-installed the software from scratch and have also downladed the latest service pack.
