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.

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 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?

how to get Super Elevation report for superelevation value at every point separated
View 2 Replies View RelatedI 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?

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?
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.

How to add super elevation detail on Profile band.
View 1 Replies View RelatedUsing 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.
I have created the super elevation to my road as you can see on the attached picture, but I can't see the super elevation on my section view.
See attached.
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.

It looks fine in Composer but doesn't show up in C3D - only straight line. Would like the same outcome as the Generic Link Code - LinkSlopetoElevation.
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.

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.
View 2 Replies View Relatedi 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.
View 9 Replies View RelatedI 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?

A few weeks ago I did not have this problem but once my computer was switched to the company's global server and c3d was reinstalled the problem appeared. Furthermore (post switchover), when a colleage of mine prepared a simple test drawing with just a line and a point, he was able to snap to that line without the point changing elevation. When he sent that drawing to me and I tried snapping the point to the object, the same problem occured with the point taking the elevation of the line object. I suspect it is a system variable issue

View 3 Replies View RelatedI received a drawing from another consultant that uses C3D 2013. When I open the drawing in C3D 2012 I get the message that it was created in a newer version of C3D so I assume he did a save as to 2010.
When I get drawings like this I copy what I need to the clipboard and paste into a new drawing (acad.dwt). This usually works fine. But in this case the drawing is almost 4 MB and contains just one arc. I purged everything I can from the drawing and it is still 3 MB.
I looked for but could not find any of the usual suspects: drawing scales, regapps, empty text objects and wipeouts. When I list "all" there is one arc in model space and 4 view ports in paper space. I did notice that there are hundreds of linetypes and text styles that cannot be purged.

I am modelling a steep channel of constant slope operating under super critical flow conditions between two small weirs. I have set up two different models to represent this:
1. A single link between the upstream and downstream weirs.
2. I have also modeled the channel as a number of smaller links with the same slope separated by nodes spaced arbitrarily along the channel length.
The two models give very different results. The former results in an unstable channel (oscillates between sub- and super critical flow) and a maximum velocity in the channel of around 1.5m/s. It seems to me that the velocity in the upper section of the channel should be higher. I assume this has something to do with the manner in which SSA averages the velocities along the entire channel link.
The second model gives more realistic velocities in the upper channel links (around 3.6m/s) and a hydraulic jump and transition to sub critical flow upstream of the weir in the lower channel. This seems more realistic. I think the trick here is to make sure that the downstream link is long enough to enable realistic formation of the hydraulic jump in the model.
