AutoCAD Civil 3D :: Pavement Thickness Taper (not Lane Width)
Aug 1, 2012
I have an "ultimate" profile that has be set for a proposed roadway the first 1500' of the roadway will be constructed at this final profile while the last 900' will be constructed for an interim design not at the full depth pavement. So my typical for the final is 9.25 inch of pavement over 14" of stone and the interim is 4" over the same 14" of stone when we transition from the 4" to the 9.25" we are using a 20:1 taper the question is how to model this taper condition and have you had any success.
i am designing a footpath. I have got my corridor and assemblies all right. but when i plot the cross section, the pavement thickness and hatch pattern is not showing.
With using superelevation wizard in Civil 3d 2012, changing the lane width is not affecting the resulted values of transion length and run-off length, Is that correct ? ( as civil is using standerd AASHTO tables which assume that lane width typically is 3.6m )
Also, There is only 2 tables for 2-lanes and 4-lanes roadway, Is it for total road width or for one directon only, and what about different no. of lanes ?
I am trying to create a iLogic Rule that will measure the Length, Width and Thickness of a part and ut it into the custom fields we have. I am having a hard time remembering how to get it to do it from the assembly level. I want to run this on the assembly and have it populate all the parts inside of it. The code below will do it for a part but what is it I add to get it to drill down into the assembly?
Then I want to add this formula to the Stock Number iProperty = <Length> X <Width> I can get it to add the values but I can not get it to add the formula to the stock number.
Where is the best place to get symbols for pavement markings and signage in C3D2009? I used to get the symbols from symbol manager in LDD. Is there a better library in Design Center?
When i am creating a assembly, the sub assembly parameters for the generic pavement structure is not showing (such as the lane width or crossfall) Other sub-assemlies show these parameters. Is this a bug or is there a way i can turn this on.
Civil 3d project. My familiary with actual road construction is quite basic.
I'm at the stage where good Civil 3d practices need to be employed when generating volumes. Attach are two files showing a road section with links and layers & also, the profile.
1. Like to turn off the links first of all and show labels instead.
2. How does the total depth of the gravel road (0.3' for gravel, 0.5' for aggregate base) factor in the profile view? What shown is the EG(in green) and FG,the top of the gravel road.
3. The cross section view: Three surfaces were used, the top of the gravel, the bottom of the base and the Existing ground, Is this correct?
4. Is there two sets of Volumes? 1. Cut and Fill areas, 2. Pavement structure: Volume of the gravel and volume of the aggregate base.
5.Refer to 4. So the Cut and Fill areas need to be done first, then the pavement structure, correct. ?
How to shut off the rendering for the pavement & curb assemblies autodesk provides?Otherwise they turn into black blobs and use a lot of ink when they are plotted.
I am trying to apply the stripping pavement subassembly to only fill situation and even though my attachment point is only the fill case it applies it to both as shown. I am trying to get this information to provide a stripping volume for fill cases only.
I have been trying to find the best/most efficient way to make a pavement grade plan for my current project. The only two ways that I know of are:
1) Home Tab->points->Create Points-Alignments->Measure Alignment then select my mainline alignment, enter a profile, enter an offset to create the points. Then assigned elevations of the points to my "pavement" surface.
2) Make lines perpendicular to your alignment (I used sample lines, exploded them to a block reference)->Make a feature line and snap at each 25' segment->Assigned elevations of the feature line to my "pavement" surface->used custom line and curve labels to label start segment z value.
My issue with option 1) is on my project there are multiple curves and I don't know of anyway that I can have the labels follow my alignment. I think the way the alignment labels work is if I would edit the label I would have to manually edit the angle and with multiple curves I don't think this would work the best.
My issue with option 2) is my project is roughly 1.75 miles long with 8 lanes and 12' shoulders, I would have to make roughly 4000 elevation points on my feature lines.
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've used the OverlayWidenMatchSlope1 subassembly to widen a new travel lane using the existing carriageway crossfall then I try to create another lane using the same assemble following the same slope but the insert point always starts on the existing ground rather the new levels from the first new widening lane.
I tried to import the Lane Toward Crown subassembly to my Lanes tab, but the import function looks for *.pkt files and all I have in the Stock Subassemblies folder are *.vb files.
Im using civil 3d UKIE 64bit, having a serious problem with adding a lane widening to an offset alignment. It is a straight alignment approx 200m length, but when i enter the parameters that is asked, at the end it says no solution!
I create Curb Return Fillet assembly with shoulder in SAC , but now i have problem with targeting , when i giving two targets it takes only first target and ignores second, could you check attached assembly and drawing ?
In my corridor I have used superelevation. In a horizontal curve which has a cross slope of 4.5%, I have an intersection. To allow for a smoother ride through a few lanes in the intersection I want to change the cross slope from 4.5% to 1%. I was planning on doing this by using a Outside Lane Elevation Method of a Profile. However, it appears that my super has precedence over my profile. Is there are way to make this work?
I'm attempting to use the Superelevation tool on an interchange. I have 4, 1-lane ramps that I need to apply superelevation to. The three issues I have (so far) are:
In the Calculate Superelvation Wizard...
1. In Roadway Type, I don't know what to choose, I'm leading toward Undivided Crowned (center Baseline ) because my assembly (as of right now) is set up as an undivided crowned roadway (with the crown on the west travel lane edge). Which Roadway Type I should choose (for a 1-lane Ramp with different shoulder widths?)
2. Moving on to the the Lanes category doesn't matters. I uncheck symmetric Roadway, hoping I can choose "0" for the number of lanes on the Left, or at least put the lane width down to "0" but can't do either. I uncheck the Symmetric Roadway and it still makes everything symmetric (it acts as though it is still checked?) I only want to show a single 15' lane. (I even tried to use undivided planar, and put both lanes at 7.5'each, but then I still have shoulder issues...)
3. Move to the Shoulder Control. Why doesn't it give me the option to do different shoulder widths? On ramps it is very common (at least in Wisconsin) to have an 8ft shoulder on the right and a 4ft shoulder on the left. How can I type in 2 different shoulder widths.
I watched the cul-de-sac placewhere and I seem to missing some functionality shown. Specifically the ability to link a transition lane to an alignment and profile via corridor properties>logical name>no width shown as the placewhere shows?
I have an assembly that contains a basic lane tranisition with a retaining wall next to the road. I have created an alignment for the lane transition to follow but the wall stays in the same place. Shouldn't the wall move with the lane transition? The sub assembly are inserted connecting each other. what am I missing?
For some reason I cant seem to target an offset alignment layout profile with my corridor lane assembly. I can target the existing the existing groundprofile with the same offset alignment, but the layout profile when targetted does not change the lane in my cross sections. I can do this with civil 3d 2010, but not 2012. I have tried other lane sub-assemblies and it doesn't make a difference.
Can't figure out how to match gutter slope to outside lane super subassembly slope. Have super eop targeting a feature line with elevations, but when i check section editor gutter slope doesn't match pavement slope.

i 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.
Is it possible to add a base depth to the transition lane assembly? I need to do volumes for my road, (pavement, base) but there is a section with a transition (which only has one depth), so that section is off.
The 2013 .NET API exposes just 10 of the 22 PartDataFields for Pipe objects. WTh (Wall thickness) is not one of them so I'm attempting to get it via Late Binding. This lisp code works, where (vl-sel) is just a helper function to select an object and convert it to a vla-object:
I am experiencing a problem in 2013. In part builder, I am trying to add wall thicknesses to the simple cylinder. I was able to add options for inside diameter and set floor thickness to a list and add options for that, but when I try to set wall thickness to list instead of constant, I get an error in the value menu.
Everything disappears and in red at the bottom, I get a message about an error in calculations. I even tried temporarily deleting the With from any calculations, but I still got the error. I have had no problems doing this in 2011 or 2009.
I have created 2 surfaces of a matierial that is buried, using drill hole data. I have a surface for the top, and then a surface for the bottom of this material. I then created a 3rd suface comparing these 2, creating an isopac contour showning the thickness of the material. My question is this:.....is there a way to make the zero (0) contour show up? I have a .5 contour interval, but 0 doesn't generate. Could i be missiing something in the settings?
