AutoCAD Civil 3D :: How To Match Gutter Slope To Outside Lane Super Subassembly Slope
Mar 22, 2011
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.
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.
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.
I 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?
Its a embankment crest (dam wall) and then sloping down at an angle to a target elevation. I want it to shoot through my topo / surface and then apply a boundary later.
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 trying to build the ditch portion of my Subassembly backwards from an offset target "DitchOffset". The elevation of this point should be derived from a point that is using Slope and Delta Y from point "P12" (see attached). Must be at least 1m from the bottom of SubBase with a 5:1 slope.
The Ditch Bottom will be variable width. I'd like to be able to select my offset alignment for my ditch bottom. Have a link from this point extend at a slope to the Target Surface to complete the foreslope.
I can't quite picture how to complete the links from the DitchOffset point. This may be complicated but the diagram identify what I'm trying to do.
I am adding on to an existing roadway. I want to match my exist.cross slope of the road way which will vary.
When I select to use the parameter reference LinkoffsetandSlope I get a slope, but it is in the wrong direction.The linkoffsetandslope is getting the grade from the existing CL of roadway and the existing edge of pavement.
I'm looking to make an assembly to follow the crown of the existing roadway which is to be milled and overlayed. In addition to being milled and overlayed there will be a curb bumpout which will be full depth pavement. The roadway does not hold a constant crown at 2%, it varies which is why I would like it to mimic the existing roadway cross slope. What would be the best way to go about making an assembly to model this. I have attached an image so that you may get an idea of the situation. I have a curb gutter line which I would like the assembly to target in both width and elevation. The single slanted hatch is mill and overlay and the double slanted hatch is full depth pavement (widening).
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 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.
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 ?
The undefined areas of a slope map now have a hatch to them and are plotting black. This map was created a month ago in 2012 without issues, upgraded to 2014 and now the undefined range has hatch!
I have a simple driveway corridor along a steep hillside. For cut, I would like to have a negative slope away from the shoulder edge. I have tried numerous approaches and all 'cut' reverts to positive. I searched and found no clear answer. It's such a short driveway, I can 'fake' it in, but I would like to calculate quantities.
I've got a surface that displays contours correctly. When I go to Surface Properties-Analysis tab, I can set an arbitrary number of ranges for contours, directions, elevations, slope arrows, etc, and they display correctly.
I can set an arbitrary number of ranges in the slope range box too, but when I click the Analyze button, Civil 3D 2014 hotfix 1 only displays two slope ranges: 0% to 2979736.0077% and 2979736.0077% to 99999900.0001%. (!)
Can I automatically have my slope patterns introduced with a command like matchprop or something similar ?
I have 284 streets and it's getting ages to finish the slope patterns on every street. Civil Engineer / Infrastructure of metropolitan transports. URL....
I'm trying to match an existing slope design that has a soft rounded off top of slope. The toe (green) is a feature line and I'm using a 1-1/2:1 slope to natural surface grading rule. You can see the rounded contours in blue that I am trying to match.
in my link "link slope to surface", i have the slope set to -2.00%. in the cross sections, it is at a +2.00%. why is this thing not linking at the defined -2%? see image.
I need to project a surface/grading (or something of that nature) across my berm and have it intersect with the inside bank. This is better explained if you see the attached image. In the plan view you see 4 featurelines. Outside TOE, outside TOB, inside TOB then inside TOE. I need to project the outside TOE across the berm (shown in the section view) then create a new featureline where the line and inside slope of the berm intersect. Note that all the elevation shots vary as does the widths across the berm. What's the best way to do this?
What formula Civil3D uses to calculate the average slope of a surface?
The formula I am using is S = I*L/A
S = Average Slope I = Contour Invertval L = Length of Contours (ft) A = Area of parcel (sq. ft)
I just had to do four parcel calcs and the percentage I find using the formula is always 1-3% lower than the percentage Civil3D spits out. I can't find anything about how Civil3D arrives at that number, it just appears. I assume that Civil3D is more accurate but I can't give that number to a client without knowing how the program arrived there.
I need to have a subassembly for a superelevation where the lane and base slope to the left and the bottom of the sub-base will slope to the right. I was using the LanSuperelevationAOR subassembly, which worked fine with my superelevation when the lane, base and sub-base were all sloping the the left, now I need to edit the slope of the sub-base only to slope back to the right at a -2%.

I can not get the slope analysis to come up with 10 slope ranges. My ranges are set to 10, but my Range details populate to 22? Screen Cap included. I've tried this with Equal Interval, Quartile, and Standard Deviation. Nothing will create 10 intervals.
My "slope analysis" surface style is set to show Slope, with the range set to 10. In surface properties, my range is set to 10.
I use slope symbols instead of contours to keep my maps less busy. Unfortunately I can only change my cut style and fill style to slope symbols with grading by right clicking on the little diamond in the grading and selecting grading properties.
I have created a surface with 3d poly lines not by creating grading and got contours that way, How can I create the slope symbols in a surface. I tried xploding them and then creating a block and using the measure tool on the 3d polylines but it doesn't do anything.
Picture 01 is the contours
Picture 1 is the contours turned off and cut/fill styles turned to slope symbols.
Please find the attached picture. It shows a surface with its data points. I extended the surface to the outer boarder shown by kriging. The slope of the surface that was added with the extension (past the data points) has an upward slope that was generated. I need the surface to stay level with the data points that are there.
How to avoid that added slope when extending a surface?
Trying to add slope markings on my corridors, and the only way I can find is to do it in the Corridor properties > Slope markings, then click add slope pattern, which asks you to select featurelines top and bottom of slope. Surely there is a way to simply switch on or off slope markings where in cut or fill?
I need to be able to do a slope analysis on a surface, but I need to have it calculate the slope in a direction - east and north. Any way to do it? Maybe even if there is a quick way to apply slope labels to a surface based on a grid - say the slope from N0.00, E0.00 to N0.00 to E 25.00
