In attached file the normal cross slope of secondary road(AB) is 2% Right to left (Right higher). and for primary road cross slope is 2% Left to Right (Left higher). I produced this junction using intersection wizard and cross slope of secondary road only starts changing from start of curb return to match the long slope of primary road. Is this possible to increase this transition lentgh on secondary road to create smooth contours.
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?
How can I make sure the annotated surface labels spot elevations from my 3d design drawing which is being xrefed into a new Precise Grading Breakout Sheet plots screened?
The Label Style which I created for the annotated surface label spot elevations has all its properties set to be ByLayer for example its color and lineweight. The Layer I assigned the Label Style was assigned to a layer with a color and plot style that should plot any object screened. Color 8 and Plot Style Screened.
What other steps am I missing to assure myself that this Label Style will plot screened in my new Precise Grading Breakout Sheet?
I also made sure that the xref drawing in which this Surface spot elevation has the correct colors and lineweights and Plot Styles in my new Precise Grading Breakout Sheet.
I have a problem with my superelevation. everything is calculated accordingly but when i build my surface from corridor after i have calculated superelevation it does not show the results. Even my cross sections view still show a normal assembly cross section. It happaned on both C3d2011 and ad C3d3013.
This is my aplicattion in Civil 3D 2014. URL....It´s a tool palette that checks the design criteria (for alignments,superelevations and profiles) according to Spanish rules.My program changes the name of each superelevation curve,for example:
---> With superelevation tool own of Civil 3D (Cuve.1,Curve.2,Curve.3)
---> With my program: (VisorNET Curva.1,VisorNET Cuva.2,.....)
If I calcule again Superelevations using Superelevation button (Calculate/Edit superelevation)of Civil 3D, Civil 3D doesn´t change the Superelevation Curve Names and appears again (VisorNET Curva.1,VisorNET Curva.2,...).Superelevation CurveName property doesn´t exist in settings:
URL....and there isn't a name template. I would like to have this property (read and write----get and set) of settings.Then, I could re-write the default Superelevation CurveName format. (name template)
I am working with SAC , and cant understand how that superelevation works, how to make my models work in CIvil 3d in superelevations... how to build it properly in SAC. I would rly love to get .pkt file with working model as example , or at least get some usefull tip.
I am currently trying to design a roadway with a reverse curve in it. I am having trouble getting my corridor to model my assembly correctly as it is showing the roadway as the generic assembly and is not adding the superelevation that is shown on my alignment. I have done the following:
1) created an alignment with superelevation wizard - superelevation diagram shows up correctly
2) Created a profile for this alignment
2) created an assembly (Road layer is LaneSuperelevationAOR) in which the right lane is set to use SE on the right outside lane and the left lane is set to use SE on the left outside lane
3) Created a corridor with the assembly and set the width targets to the offset alignments (I.e. the lines that are the edge of pavement)
The corridor does not show the superelevation values based off of the alignments superelevation that it has calculated. I did get the supers to show when i tied the Future EOP to the existing surface, however i do not want it to tie in, I want it to just show the values that were calculated.
Is there a way to get this to show without referencing an additional profile? Also, on my first curve i want to keep the right side at a -2% slope and raise the left side to 2% slope (RC). Is there a way to limit the calcuations to only use a reverse curve?
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 have an alignment I need to edit that has a reverse curve. The first curve was made with the "Floating Curve (from entity, radius, through point)" and the second with "Free Curve Fillet (between two entities, radius)"
When I delete one or both curves i lose all the superelevation data beyond the editing location due to the temporary spit in the alignment. The superelevation data is all manual. This is a trail and the super is based on drainage not curves.
how to edit the alignment with a temporary split and not lose the superelevation data? I have not found a way yet to remove the reverse curves and not have a temporary gap.
Is there a way of adding superelvation data such as full superelevation cross slope to an alignment curve label in plan view?
In my case we add a label for each horizontal curve with critical curve data such as PI Station, Delta, Degree of Curve, etc... but I can't seem to find a way of adding any superelvation information to the plan view as a label. Ideally I would like to be able to add the maximum cross slope value and superelevation critical stations to the label.
There is a way of adding the superelevation critical stations a labels to the alignment similar to how PC's or PT's are labeled, but it does not give the cross slope value.
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 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.
I've attached a screenshot of some "webbing" I have going on between regions in my corridor. As you can see on the left, there's the start of a left turn pocket lane, which is why I have two different assemblies. This is just one instance, but this is happening along my entire corridor. I've given up on trying to resolve and have made gaps in my corridor. But me being an engineer, gaps bother me and would rather figure out a solution. I'm wondering if it has anything to do with point codes?
I have a building pad where I created a grading of 5:1 to existing grade. I want to change one side to 20:1. How do I go about transitioning the 5:1 to the 20:1. I create the 20:1 and the contours just dead end into the 5:1 grading area
I'm designing a single 2% cross flow blke path. I wanted to reverse the cross flow so I created two corridors, one flowing to the left and one flowing to the right along the same tangent centerline. I want to add a 50 foot warp transition in between them. I'n not sure how to do that. I thought of the intersection design but that won't work.
I have a large fill area directly dropping to to a large cut area. All of the above work is in rock, There is a retaining wall along a section of the "cliff face" but not at the ends where the cut and fill meet.
I would like to transition the fill batter on to the cut batter to enable the filled area above to be self supporting.
I am working on a project where some of the corridors require different daylight slopes. I need to transition between a region with 2:1 slope to a 10:1 slope. My local civ3d support said something about using grading tools to achive that.
What I understood was that my assemblies should not have any daylight sub-assembly and that i should grade the corridor and than add a transition zone between the different gradings. Did I understand correctly?
I often have to do storm pond surfaces that (for the purposes of planning) are flat on the bottom. These surfaces are created from a combination of survey data and grading groups and the tin of these surfaces is perfectably acceptable. However, when contours are shown, the flat bottom is shown with contours jig-jagging all over the place.
The attached image shows a comparison of the same pond. The top was created with survey data and grading groups; the bottom was created using contour data only. The generated surface on the top shows the bottom contour going in different directions and has parts where the an expected contour is missing.
How to correct/manipulate the surface to show a proper flat surface?
