AutoCAD Civil 3D :: Alignment / Corridor / Super Elevation Error
Jul 16, 2012
Using Civil 3D 2012 SP 1 on Win7 Pro 64-bit.
Is there any reason why a corridor model would not be respecting the manually entered super elevation values in the alignment? I have several stations that should be calculated with even super elevation values, but they aren't. For example, at station 0+080 on my alignment the left crown should be running at -3%, but it is actually being calculated at -2.47%. It isn't just one station; it's most of them. No overridden stations, vertical targets, etc in the corridor. Just a fairly straight-forward align (hor/vert) with super, simple assembly (two lanes, shoulder, daylight), simple corridor.

With Civil 2010 I used superelevataion to transition a street's cross fall from left to right. It was very straight forward with 2010.
Now with 2011 it appears that I cannot add superelevation to an alignment with any curve and change the crossfall of a street from left to right over 20m.

I've got a highway project for which I'm modeling the corridor but the design profiles given to me are for the right lane top edge (ETW) and not the centerline (crown). This is an undivided planer roadway with a typical 2% cross-slope. How can I use that profile for the right edge to run my corridor? I can't seem to get the corridor to use the super table that is attached to the centerline when I use an offset assembly. Is an offset assembly the right way to go with this design?
What I've done just to get going is to take that right edge design profile and draw it in my centerline profile view, then lower it 0.24' (which is my 2% normal cross-slope for a 12' lane) and then use that as a centerline profile and let my normal super assembly and table data control the corridor through the supers. So far that is working--but is there a better way to do this?

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'm working on a runway in Civil 3D 2011. I want to transition cross slopes along the runway. i.e. 1.5% for sta 1+00 to 10+00 and then transition into 1.0%. I thought super elevation would be the best way to do this (I dont want any actual super elevation, just transitions in cross slope). When I select the alignment and "Calculate/Edit Superelevation" i get the following message in the commanding line:
"_AeccCalcEditSuperelevation No superelevation data has been calculated for the selected reference alignment." It does not bring up the wizard.
My runway alignment doesn't have any curves and I'm thinking that's the problem. Is is possible to create super elevation without curves?

I am using Civil 3d 2013 and I am trying to calculate the superelevation information in which the curve will max at 2%. Is there a way in which the superelevation can be calculated using the superelevation wizard in which a 2% SE is the max? So far it will only let me use the SE for 4% local roads and I have to edit it using the SE layout.

I have a superelevation on an alignment but want to remove this as its overriding the assembly I'm using. I have tried using the tabular editor within edit super elevation to remove the various sections but it's still not working. How can I remove the entire super elevation and revert back to my standard assemblys?

I want to know how exactly the super elevation within SAC works. I am building few SAs and some are just multi layered lanes and others are lanes with solder, etc.
How do I add super elevation to SA, After adding Super elevation to Parameter what is the next thing to do.

I need getting a roadway to transition horizontally for a turn lane. If it were straight without super, it would be easy. However, the transition happens in a curve that needs to be super elevated.
I know I can use the lane transition assembly and set it to "change offset and grade" but with that, I would have to manually calculate my EOP elevations.
Is there a sub assembly with the ability to use the centerline super elevation data as well as transition horizontally?

I have a section of road that has super elevation from -6% to +6%. The asphalt layer (top green) supers from -6 to +6 but the base course (red) only goes from -4 to +6. I attached a sketch for some visual information.
What subassembly recommended for this scenario?
Is there a way I can set max values for the subgrade? Or an assembly where I can use superelevation for the top and for the subgrade?
I am using C3D 2012 but can use 2013 if it makes a difference.

I'm a little surprised with this....
I dont imagine how c3d does this .

We don not show CL profiles and only show the gutters on the CL profile view. We also do not used profile bands.
I need to show Superelevation on both left and right profiles complete with labeling.
Short of creating a seperate alignment for each, sampling the corridor surface, superimposing it onto the CL profile view and then creating a layout profile by drawing over the sampled surface.

Our provincial standard requires subgrade and subbase surfaces to have a normal cross slope of -3%. The base and asphalt surfaces have a normal cross slope for the driving lane of -2% and -5% for the shoulder.
I have been trying to figure out how to do this in C3D. I have thought of different ways of handling this for a straight tangent, but have not tested them. What is causing me the most grief at the moment is how to handle this in a curve with super elevation.
The transition will be different for -2%, -3% and -5% Runout distances.
Can C3D handle this? What about using Subassembly Composer?
(I should mention that I have tried with Subassembly Composer, but I am not sure how to deal with superelevation. -

As shown in the attached drawing, the station label where the superelevation transitions back into normal crown shows with 4 decimal places. We have verified that all precisions are set to 0.01ft. The normal crown station at the begin transition shows with 2 decimal places.

I did a user defined super for my road. This worked well. However when I deleted the super data. To try something else. The corridor shows 0% camber or crossfall. How do I get the corridor to follow the default crossfall in the assembly again?

Alignment, profile, assembly and corridor have been setup. i have setup the superelevation calculations and did the super elevation view and it looks right, but for some reason the super elevation won't apply to my section view assemblies or the corridor editor.

When creating an alignment from corridor feature (ditch invert level), the created alignment is not following the selected line (see image bellow). The alignment seams to be created from the first point of the feature line to the last point and ignores all the other points. The vertical alignment created at the same time seams to be correct.

how to create corridor, and I have a question about assembly elevation targets.
When creating a corridor, the profile is required as dependent object, which gives the elevation of the centerline of the road. Based on the definition of assembly, the elevation of the corridor at the offset targets can be determined by the profile. My question is if the assembly elevation target specifies the elevation at the offset target too? If so, why both profile and assembly elevation target are required?

I want use my corridor where I need it and not use one in certain areas. For a proposed dike. Some places doesn't need to be replace.
So I need a way to use my section on the alignment. where I can find that option?

My alignment runs on the road center line and ends at the center of the cal-de-sac bubble. My corridor runs to the middle of the cal-de-sac. I need to shorten the corridor to end where the constant road width ends and the bulb of the cal-de-sac begins. I can shorten the Corridor on the alignment or do I need to create a new alignment to the desired length?

During modelling an intersection I need a corridor edge as target for onther region (attached picture),
I made the alignment from corridor but unfortunately there is no option for that aligment to be dynamic!!!!!
every time I changed the main road layout, I have to delete the Edge alignment and make a new one.

I have the centerline of a berm constructed using a 3D polyline. I want to use this centerline as the Alignment that I need from which to create a Corridor. When I try to create an Alignment from objects, I can only use a 2D polyline, not 3D. The berm has a slope to it and I need to have the assembly follow that slope as I create the Corridor. Do I need to create the Alignment in 2D and then edit the points for elevation?

I'm trying to create a trench with pipe corridor along the alignment.
What I've did:
-create an alignment;
-create a pipe nework based on my alignment;
-then I made a profile with my pipe network and draw profile;
-create an assembley;
-create a corridor with one baseline.
When I've checked the corridor I found some weird spotes that are linked to zero elevation.
I've created another alignment from daylight of my corridor, but it doesn't worked.
Where mistake is???
Trench in object viewer
Profile of major alignment
Profile of Daylight

I'm having problems getting super elevation data to transfer to different drawings by means of an alignment data shortcut. I know alignments hold the super elevation data so I've gone into my alignments data shortcut, input my super elevation data, saved and closed. Now when I open my finished grade drawing, reference in my alignment and profiles, then create a corridor from that information, my super elevation didn't transfer with the reference.
I pulled cross sections and it appears is has no clue there is any super elevation data. Also, I tried bringing it directly into the drawing I'm doing my corridors in and it erred saying I must be in the parent alignment drawing. Data shortcuts are pretty much useless to me if super elevation data doesn't transfer.

i am trying to get the coordinate value for the current station in the subassemblies.
i found
Autodesk.Civil.Roadway.DatabaseServices.BaseBaseline.StationOffsetElevationToXYZ(ByRef Autodesk.AutoCAD.Geometry.Point3d) As Autodesk.AutoCAD.Geometry.Point3d
but how you get the basebaseline?
in the alignment object there is no convert station to coordinate only coordinate to station. which is useless in this case.

Because there is a PI in my alignment, the section lines in my corridor are overlapping creating problems with the surface. Is there anything that I can do in this situation?

For an intersection, I am trying to create an alignment and profile from the Lane (edge of traveled way) of my main road for the intersection lanes to tie to. I just did this yesterday on this same corridor without any issue, but today it doesn't create the alignment correctly. It doesn't actually follow the feature line that I select. The alignment is in orange and the green line is the lane line. Notice that the alignment isn't following the lane line.
What would cause this? It worked fine doing the exact same thing yesterday, but today it's not.
