Revit :: Super Elevation And Side Friction In Curved Sloped Surfaces For Curves
Oct 20, 2011
Is there a way to avoid super Elevation or Side Friction in Sloped Surfaces for Curves, such as Building Pads, Ramps, Floors, etc.. Is it mandatory.. ?? Its a problem all the time worrying about matching levels in topo surface and floors for gradual slopes in site and side friction in sloped ramps or sloped building pads.. that matching line between levels doesn't look good while giving presentations..
I have also attached an image for reference.. both the sloped surfaces are building pads..
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?
Is it possible to project an elevation drawn in CAD onto a curved wall in Revit?
The pattern of the cladding is very complicated and varies in both directions (curves) so it was easier to draw in in CAD, but I would like to project it on my curved wall in Revit, co that I could calculate the cladding areas accurately.
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 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.

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.

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.
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.
I read a 2009/10 thread, "Rotating lighting", describing how to work around the problem of family lighting fixture members not rotating. I would hope there is a better solution today.
I simply want to place a lighting fixture - std 2x4 flourescent, on a 7 deg sloped ceiling. The axis of rotation is the long run of the light fixture. Is this not possible in Revit 2013?
Or, do I have to dredge up the work around from 3 releases ago and attempt to discern how to make it work?
It seems like I should just be able to set the family to use a work plane-based assignment and then place it with the correct work plane active. That is not happening. The light fixture doesn't want to rotate the 7 degrees to align with the work plane.
I am working on the project with sloping roof. I have drawn beams with slope. however when I am drawing slab with slopes I am not getting this slopes. There is gap between the beams and slab. I have attached screen shot for more information. Also I need to apply loads for this sloped roof.
Working on a project with a green house. I created a roof using "roof by footprint". I selected "sloped glazing" and assigned mullions for the various conditions as well as spacing.
The walls below are curtain walls. When I create the roof, the mullions are oriented the wrong way. How do I control the orientation of the mullions?
In desperation, I mirrored the roof about a vertical axis. See images below.
This corrected the orientation for me, but I must believe there is a better way! A "proper way"... Did I miss something in the initial creation of the roof? I changed the sloped glazing of the roof to a basic roof. When I do this I notice the roof moves up.
I assume this is when the orientation of my roof inverted...
I need to model a building that cascades down a steep sloped hill. Should I create a toposurface first and then model onto that or should I make my model and then apply it to a toposurface?
I have a 6 pitch connecting to a 9 pitch roof. I go and make an eyebrow dormer along the 6" pitch roof and the dormer automatically is drawn as a 9 pitch with a crazy peak (almost church like). I cannot adjust the pitch of the eyebrow to make it look appealing.
I made a metal standing seam roof by putting mullions on sloped glazing roof. Is there a way to extend the mullions past the edge of the perimeter of the roof?
I am working on creating a building shell that is elliptical. i managed to draw it 3d through lofting. now i am trying to have a hexagonal grid on it so i can draw hexagonal large structural ribs and then in between the ribs hexagonal glass grid.
I have a situation of one sloped floor connecting two horizontal floors. They build together a continuous surface.
I need to join them and have the layers be continuous along the structure. If they were roofs, no problem, I could use the "roof by extrusion" command.
Should I do that? If I try to use floors.....
When I model them as three separate floors, and then Join them, it doesn't work. meaning that the layers within the floor don't match (well, they can't, in fact! I have to move the floor behind!)
If I model one single floor and then add split lines, and move them... it does work. BUT..... I have a stairs on top of it! the stairs have a different slope than the floor, and i need to build a variable layer that fills the void between the floor and the stairs.
So my hypothesis was: I put a sloped floor through the slope arrow... and then adjust one variable layer to do the inflill...
My dream would be to join then floor and stairs.... The material is the same
Having a time getting ribs to align 2m below top of ridge beam, and connect to curved wall below. I created one, then arrayed, but the radius changes at each 2.5 degree interval. I don't think I should have to calculate the % radius change to get the beams to do this. Some constraint button maybe?
Not sure if editing a wall profile is the best way to model this, but it's working.
