AutoCAD Civil 3D :: Superelevation For 1-Lane Ramp (different Shoulder Widths)
Apr 3, 2013
I'm attempting to use the Superelevation tool on an interchange. I have 4, 1-lane ramps that I need to apply superelevation to. The three issues I have (so far) are:
In the Calculate Superelvation Wizard...
1. In Roadway Type, I don't know what to choose, I'm leading toward Undivided Crowned (center Baseline ) because my assembly (as of right now) is set up as an undivided crowned roadway (with the crown on the west travel lane edge). Which Roadway Type I should choose (for a 1-lane Ramp with different shoulder widths?)
2. Moving on to the the Lanes category doesn't matters. I uncheck symmetric Roadway, hoping I can choose "0" for the number of lanes on the Left, or at least put the lane width down to "0" but can't do either. I uncheck the Symmetric Roadway and it still makes everything symmetric (it acts as though it is still checked?) I only want to show a single 15' lane. (I even tried to use undivided planar, and put both lanes at 7.5'each, but then I still have shoulder issues...)
3. Move to the Shoulder Control. Why doesn't it give me the option to do different shoulder widths? On ramps it is very common (at least in Wisconsin) to have an 8ft shoulder on the right and a 4ft shoulder on the left. How can I type in 2 different shoulder widths.

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.

In my corridor I have used superelevation. In a horizontal curve which has a cross slope of 4.5%, I have an intersection. To allow for a smoother ride through a few lanes in the intersection I want to change the cross slope from 4.5% to 1%. I was planning on doing this by using a Outside Lane Elevation Method of a Profile. However, it appears that my super has precedence over my profile. Is there are way to make this work?

I am building an assembly for a shoulder widening. the sholder is 5' paved plus 5' stabalized tying to existing grade at a 4:1 slope. The two shoulder sections are showing up in the cross section but the tie-down is not. I have checked the target and it is set properly to the existing ground.
See below.

I need to create an assembly that will give me the volume of a new shoulder along an existing road, as show in this picture.
I can easily make an alignment along my edge of pavement, and match the existing elevations, but I need to hold the cross slope constant AND the shoulder slope constant, and have the bottom of the shoulder slope to a target 2 feet off of my ROW.

I am trying to model a DOT project in a fashion that allows a corridor surface creation for not only the finished surface, but also the datum surface. This is a machine control project currently under construction. One of the DOT's typical sections includes a shoulder subassembly with a grade break in it. This particular assembly varies in width at the grade break. I would like to have the option for a target width alignment at the grade break.
See attached sketch.

How do you merge a ramp on to the main highway using corridors? Also how would you make that surface with two different alignments? I have my main road alignment and a ramp that comes on to it so the problem I'm having is making my 3d model with the road and surface combine.

how to create a new sample line group and a new sample lines within that slg: URL....I have checked what is the default sample lines width (create sample lines command):
Autodesk.Civil.Settings.SettingsCmdCreateSampleLines SobreanchosSamples = default(Autodesk.Civil.Settings.SettingsCmdCreateSampleLines); SobreanchosSamples = civilDoc.Settings.GetSettings<Autodesk.Civil.Settings.SettingsCmdCreateSampleLines>(); Settings Cmd Create SampleLines SettingsCmdSwathWidths anchos = SobreanchosSamples.SwathWidths; double anchoIzquierda = Convert.ToDouble(anchos.LeftSwathWidth); double anchoDerecha = Convert.ToDouble(anchos.RightSwathWidth);
But how can I put these values (left width and right width) for a new sample line?Sample line class doesn't have "left width" or "right width" property ¿? Do I have to create a new vertex? However I think that I can´t add new vertex in vertex collection.

I'm working on a windfarm access road with tight bends that need to be 2.5m wider than the straights. I have created offset alignents and the corridor with no problem but how can I label the widths to show the variation in width at the various locations. The road is at the full width (7.5m) between tangent points and then tapers to the standard width of 5m
I have shown simple aligned dimensions on the screenshot but I'm sure there will be a way to do this automatically - won't there?

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)

Superelevation curve criteria specifies axis of rotation but the assembly does not contain pivots.
okay i got this Before , just when i wanted to change in the Super Elevation Wizard , to outside lane rotation , i recently used AOR type , but yet no luck. also in my profile the super elevation the Cross slop Band : i always no matter what a rotation about center line.

I've used the OverlayWidenMatchSlope1 subassembly to widen a new travel lane using the existing carriageway crossfall then I try to create another lane using the same assemble following the same slope but the insert point always starts on the existing ground rather the new levels from the first new widening lane.

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?

I have an alignment I need to edit that has a reverse curve. The first curve was made with the "Floating Curve (from entity, radius, through point)" and the second with "Free Curve Fillet (between two entities, radius)"
When I delete one or both curves i lose all the superelevation data beyond the editing location due to the temporary spit in the alignment. The superelevation data is all manual. This is a trail and the super is based on drainage not curves.
how to edit the alignment with a temporary split and not lose the superelevation data? I have not found a way yet to remove the reverse curves and not have a temporary gap.

Is there a way of adding superelvation data such as full superelevation cross slope to an alignment curve label in plan view?
In my case we add a label for each horizontal curve with critical curve data such as PI Station, Delta, Degree of Curve, etc... but I can't seem to find a way of adding any superelvation information to the plan view as a label. Ideally I would like to be able to add the maximum cross slope value and superelevation critical stations to the label.
There is a way of adding the superelevation critical stations a labels to the alignment similar to how PC's or PT's are labeled, but it does not give the cross slope value.

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.

I have an "ultimate" profile that has be set for a proposed roadway the first 1500' of the roadway will be constructed at this final profile while the last 900' will be constructed for an interim design not at the full depth pavement. So my typical for the final is 9.25 inch of pavement over 14" of stone and the interim is 4" over the same 14" of stone when we transition from the 4" to the 9.25" we are using a 20:1 taper the question is how to model this taper condition and have you had any success.

I watched the cul-de-sac placewhere and I seem to missing some functionality shown. Specifically the ability to link a transition lane to an alignment and profile via corridor properties>logical name>no width shown as the placewhere shows?
