AutoCAD Civil 3D :: Super Elevation Corridor With ETW Design Profile
Aug 15, 2012
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?
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.
I need to design a project but ı cant..ı have two profiles in use for one alignment..ı want to use left profile for left side, use right profile for right side.and ı want to draw cross section only one..how can ı design like this project..
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 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.

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.
differences in elevations of points along Profile 2 (the proposed new road elevation) and Profile 1 (the existing elevation/surface) should be computed and shown right above the Profile 2 line. For example, if at a certain point PT 1 the elevation of the proposed road is 132.44 meters and the elevation of the existing surface is 132.45 meters, the difference is -0.01 meters and it should be shown exactly above the Profile 2 line (or a little bit above it) but not on it. The same should be done for every chosen point along the proposed profile.
So far, I have done this manually, by dragging the difference (already automatically computed and shown in one of the bands below the profiles) to the correct place for every single point. However, I don't know how to do this automatically.
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?
Im currently having problems with my profiles showing vertical curve data on a superimposed profile. The data shows on the normal profile however when i superimpose it to another profile i cant get the program to show it.
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 pretty new to subassemblies and corridors and I think I have the jist of it but I have a few questions.
How do I lower stations of my corridor? I am making a grassed waterway and my corridor seems just ride on the surface. I get to the parameter editor but the elevation design value is grayed out, so I can't change it.
My company had always used LDD until we were mandated to switch, our first project in Civil 3D is in the works. So far we have gotten through the beginning stages (alignments, profile, corridor, assemblies) but we are having a major issue with where to go from there. Right now I am trying to complete the design line work on the plan (wheelchair ramps, driveways transitions and signage) As of now I cannot get anything to line up easily with the corridor. I have been able to snap to the corridor so I can create a line at that exact spot to be correct, but then when I offset it will not change the elevation, I tried doing feature line and projecting the feature lines to the surface and some of it works but it becomes very buggy. My transition lines don't transition and some other lines I would expect to be at the same elevation have major grade changes. How to create the luinework at the correct elevation and with correct transisions along your corridor and surface?
I only get 2 choices when selecting corridor feature line to create profile - ETW_base, and ETW_sub. My Subassembly has 2 pavement sections, a base and subbase section. I need the top of pavement profile.
