AutoCAD Civil 3D :: Adjust Superelevation / Cross Slope Transition On Intersection
Dec 19, 2013
In attached file the normal cross slope of secondary road(AB) is 2% Right to left (Right higher). and for primary road cross slope is 2% Left to Right (Left higher). I produced this junction using intersection wizard and cross slope of secondary road only starts changing from start of curb return to match the long slope of primary road. Is this possible to increase this transition lentgh on secondary road to create smooth contours.

i need a shoulder subassembly that varies slope in relation to the lane superelevation slope. i know that i can get a subassembly for the shoulder that will follow the alignment superelevation xml data but in my case i can't use it because we are just adding a shoulder to an existing road. we're not changing the superelevation of the existing road, just milling and overlaying and widening. right now i've created a profile of the outside edge of the shoulder that gives me the correct shoulder slope but whenever i change my centerline profile i have to redo the shoulder profiles which is a real time suck.

my surface is way through the in and out transition of my superelevation. the waves are dependent on frequency (ie if i change from 1m to 5m the waves get longer.

Any opinions or tips on using the Intersection Wizard to create an intersection and then editing it to incorporate a spandrel or am I better of not even using the wizard and creating the spandrel from feature lines/alignments?

Created intersection added that to existing corridor. Then went to cross section sheets and the cut , fill and strip show up but no subassembly surfaces show for the intersection .

Is it possible in civil 3d to input a cross section of superelevation as parabolic rather than straight section in civil 3d. We are looking at a parabolic bend of 40 degrees.

Along my corridor I have different assemblies I used. My sidewalk is curb side in some locations and in different locations there is a boulevard between the curb and sidewalk. I want to transition between these different assemblies and I want that transition to show up in the cross sections I cut. Isn't there a way to tell Civil 3D to transition from one assembly to the next one as you could in Eagle Point?

I am adding on to an existing roadway. I want to match my exist.cross slope of the road way which will vary.
When I select to use the parameter reference LinkoffsetandSlope I get a slope, but it is in the wrong direction.The linkoffsetandslope is getting the grade from the existing CL of roadway and the existing edge of pavement.

how to create the transition portion of a corridor design where my road cross slope has to uniformly go from 3% to the right to 3% to the left. I have the two regions set up, but I cannot get that "middle" or "connecting" region where the cross slope is "rotating" around my road profile center line to create this "+3% to -3%" transition.
I have been searching the internet and this forum, but cannot find a good explanation. There is info out there about setting vertical offsets, but not sure how to do this so the cross slope is uniform all the way through this region (i.e., making sure that if the slope is 1.234% on the right side, I will get 1.234% on the left side, etc.)

I have an assembly that contains a basic lane tranisition with a retaining wall next to the road. I have created an alignment for the lane transition to follow but the wall stays in the same place. Shouldn't the wall move with the lane transition? The sub assembly are inserted connecting each other. what am I missing?

I have a fairly simple corridor, however, I had to modify the alignment, rebuild the corridor and resample cross-sections. Now my right daylight slope won't show up. It shows up in the section viewer, but not the cross-section. I had this problem once before and fixed it, but now I can't remember how I did...I have all targets, sections sampled match corridor sampling etc.

how to have exisitng cross slopes display on a bank of corridor cross sections...I see lots of posts on this but I am having trouble finding the answer. The link below from Add a section view grade label only adds "A" slope label.....I want all of them in all of my sections.

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?

With the default cross slope 2% in place and no profile targets, section views with subject sub assembly come up at 0%
there's some polyline width targets but no verticals...

The intersection wizard makes dynamic EOP profiles based off of the cross slope from the centerline. Well the intersection tool doesn't always work with funky intersection layouts. Is it possible to manually create a dynamic EOP profile based on the cross slope from the centerline profile?

I am trying to create an intersection design using the Intersection Tools in C3D 2012. I followed the steps in the tutorials, created a corridor on the major road, splitted the regions, created the intersection and added it to the major road corridor, and connect the regions with the intersection portion.
I used the same assembly throughout the design just for simplicity, however, i notice that there are gaps of curb between the curb return section and the through section (as outline in red rectangles).

Can you not perform a slope-slope intercept to place a PVI? Essentially holding the sta and elev of the PVI's directly before and after the PVI of interest and changing the grade in and out so that the sta and elev of the PVI of interest are changed.

Can't figure out how to match gutter slope to outside lane super subassembly slope. Have super eop targeting a feature line with elevations, but when i check section editor gutter slope doesn't match pavement slope.

I am in the process of transitioning from land desktop to Civil 3D. I design roads in steep terrain and sometimes need to have my catch (daylight) slopes change. So my question is, how do I change a daylight slope at a specified depth? For example, from the shoulder of the road I want a 3:1 fill slope to a depth of 10 feet than change to a 2:1 slope until it catches the existing surface. Can this be built into a subassembly such that if the fill is less than 10 feet it will daylight correctly at a 3:1 and if the depth is greater than 10 feet then it carries the 3:1 for 10 vertical feet and then changes to the 2:1 until it daylights?

I have a problem with my superelevation. everything is calculated accordingly but when i build my surface from corridor after i have calculated superelevation it does not show the results. Even my cross sections view still show a normal assembly cross section. It happaned on both C3d2011 and ad C3d3013.

Is there a way to retrieve superelevation values from Alignment properties to show on, for example curve tables?. I would like to display the super information along with curve geometry information.

How to use the superelevation. I read that I have to enter this command:
if((Side=Left)AND(SE.HasLeftLO), SE.LeftLO,
if((Side=Right)AND(SE.HasRightLO), SE.RightLO,
CType(slope,Double)))
but I don't know where, and I just want to create a simple assembly with a slope and delta X and having a lane outside superelevation for the both side.

I have an alignement to which I have applied superelevation.
The superevation has been applied and the alignment has been annotation and it shows the change from camber to superelevation on the curves.
However when I create a surface of my corridor it does not show the superelevation, the surface is showing a cambered alignment throughout.
I have created a new alignment, a new corridor and surface and still the same.

This is my aplicattion in Civil 3D 2014. URL....It´s a tool palette that checks the design criteria (for alignments,superelevations and profiles) according to Spanish rules.My program changes the name of each superelevation curve,for example:
---> With superelevation tool own of Civil 3D (Cuve.1,Curve.2,Curve.3)
---> With my program: (VisorNET Curva.1,VisorNET Cuva.2,.....)
If I calcule again Superelevations using Superelevation button (Calculate/Edit superelevation)of Civil 3D, Civil 3D doesn´t change the Superelevation Curve Names and appears again (VisorNET Curva.1,VisorNET Curva.2,...).Superelevation CurveName property doesn´t exist in settings:
URL....and there isn't a name template. I would like to have this property (read and write----get and set) of settings.Then, I could re-write the default Superelevation CurveName format. (name template)

I am currently trying to design a roadway with a reverse curve in it. I am having trouble getting my corridor to model my assembly correctly as it is showing the roadway as the generic assembly and is not adding the superelevation that is shown on my alignment. I have done the following:
1) created an alignment with superelevation wizard - superelevation diagram shows up correctly
2) Created a profile for this alignment
2) created an assembly (Road layer is LaneSuperelevationAOR) in which the right lane is set to use SE on the right outside lane and the left lane is set to use SE on the left outside lane
3) Created a corridor with the assembly and set the width targets to the offset alignments (I.e. the lines that are the edge of pavement)
The corridor does not show the superelevation values based off of the alignments superelevation that it has calculated. I did get the supers to show when i tied the Future EOP to the existing surface, however i do not want it to tie in, I want it to just show the values that were calculated.
Is there a way to get this to show without referencing an additional profile? Also, on my first curve i want to keep the right side at a -2% slope and raise the left side to 2% slope (RC). Is there a way to limit the calcuations to only use a reverse curve?

The superelevation view seems to ignore any station equations applied to an alignment.

I found super elevation labeling for profile, but not for alignment in plan view. Is there a way to label alignment, f.x. in critical points of super elevation automatically?
