So I need an sub assembly similar to the SuperLayerVaryingWidth, but combined with BasicLane Transition sub. If the SuperLayerVaryingWidth sub would follow an ETW profile to set slope, then I would be set. Any tips on how to create this? I'm pretty rusty at building custom subs.

View 3 Replies View RelatedWe have just started using Civil 3D. I need to be able to create an assembly that will place a sidewalk at varying offsets (it is too random to make seperate assemblies). I have tried making an alignment of the back of the walk and attempted to use targets in the corridor to achieve this .
I will attempt to attach the DWG that I am working on. The Main alignment is PR-1 as is the corridor and the alignment that i need the back of the walk to follow is PR-1 BWR.
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?

How I can do this between two curvy lines so the gradient adjusts to the changing thicknesses? In the second two jpegs I'm fudging the effect with the brush tool. But this is not precise enough for what I'm trying to do.
I want to use this for traditional animation drawn frame by frame. So if I went in with the brush tool in each frame, the gradient would be stroking and freaking out when you watch the animation.
Let's say I have an assembly called Original, as shown below with a 6m wide lane. Now I want to target it to 8m wide for some road widening. Now, will it stretch along the slope of the subassembly (Case 1) until 8m width, or will it just shift laterally to 8m (Case 2)?
I know that we can set the default slope of it, but I'm not sure if it gets overriden due to the Target-width process.
Would be interested in a strategy for a varying depth overlay, i.e. where the overlay assembly follows a centerline design profile rather than a pavement depth up from existing grade. Then the trick would be for the software to calculate the asphalt volume between the new top surface and the existing roadway surface.
View 8 Replies View RelatedI have a case with the Subassembly Composer where I have 3 varying depths. InsideLane, OutsideLane, and Shoulder. My Base shape below these 3 shapes will not setup properly. I understand why, it's because the varying depths will create a potential step up or down situation depending on the depth of the top 3 shapes. This prevents the definition of the Base Shape.
For the sake of quantities I'd like to create a Base Shape. I could create Base1 Base2 Base3 (one below Inside Lane, Outside Lane, and Shoulder). I would prefer not to for clarity purposes.
How could one approach this? I'm thinking that I need some conditional components to clean this up. I'm not a pro writing expressions. I basically need to define the links that define the varying depths between the top 3 depths. I need to create another point and link if the depths vary, and that link needs to be included within the shape definition for Base.
how to create the transition portion of a corridor design where my road cross slope has to uniformly go from 3% to the right to 3% to the left. I have the two regions set up, but I cannot get that "middle" or "connecting" region where the cross slope is "rotating" around my road profile center line to create this "+3% to -3%" transition.
I have been searching the internet and this forum, but cannot find a good explanation. There is info out there about setting vertical offsets, but not sure how to do this so the cross slope is uniform all the way through this region (i.e., making sure that if the slope is 1.234% on the right side, I will get 1.234% on the left side, etc.)

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 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?

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 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'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 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.
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.
