AutoCAD Civil 3D :: Corridor For Projecting Transverse Slope?
Sep 13, 2013
I am doing a overlay design for a runway.
I have alignments and profiles for the centerline and 12.5m either side. I would like to create a surface from a corridor by using the three profiles but extending the slope beyond the 12.5m either side.
I can easially create a surface between the three profiles and alignments, however I would like to extend the surface outward a further 10m in both directions at the same transverse slope. note that the transverse slope is variable across the entire runway.
I tried this using the "LinkOffsetAndSlope" generic link by making each subassembly 22.5m long and linking only to the profiles 12.5m from the centreline. However it seems it simply applies the levels from the 12.5m offest profiles at the full distance of 22.5m.

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?

On my corridor I am using Link Slope to Surface, using a 3:1 slope. But it is giving me a 3:1 slope radial to the corridor - what I really need is a 3:1 slope between the contours themselves. On the inside of a tight curve, this makes a big difference. See the attached screenshot. Is there a workaround for this?

I am trying to build a corridor using a conditional slope assembly that considers the roadway and links into the lots.
The corridor is divided into 3 regions. All targeting has been assigned.
The first region appears fine. The second and third show no links beyond the roadway.

Designing a tailing dam I use a corridor model changing slope grade from 1:2 to 1:2.5.
There are assemblies and subassemblies with shapes defined for each slope grade, LinkMulti with no target, but how do I make the transition from one slope grade to another one?
In corridor properties I included two regions for each slope grade.
For grading there is a transition function. But the transition for corridors?

how to have exisitng cross slopes display on a bank of corridor cross sections...I see lots of posts on this but I am having trouble finding the answer. The link below from Add a section view grade label only adds "A" slope label.....I want all of them in all of my sections.

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.

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 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?

I have created a surface from a corridor. I set the boundary of the surface to the daylight of the corridor. In some areas of the corridor the surface does not triangulate see attached.

Copy a corridor successfully? I'd like to try this just a little worried about the explosion of evil this may cause to my Civil 3D session.
Even all the properties of the corridor setup from one to another would be useful. I'm building one corridor and an 2nd one that matches everything except I need to replace my Assembly with one meant for stripping.

My corridor surface is not matching my corridor top links. see attachments. this is affecting my volumes!
The section-plan(surface red).png is showing the section editor and the plan view. the red highlighted line in section is the corridor surface and as you can see in plan view the surface is incorrect and wiggly.
The pdf is all my sections with the red linework being the corridor surface.

I need to project some of the points and figures to the profile view and I'm not making any progress. I found the ProfileProjection class in the object browser, but I'm not sure how to handle the first argument (ByVal unmanagedPointer AsSystem.IntPtr,) or even if I'm on the right path. I'm guessing that it should work similar to other Create() methods by referencing an ID, then later calling a projObject.Draw() or something similar.
Below is a snippet of the survey point section. I'm iterating through each survey point in the xml data. I hope to create the projObj for each CL shot as a starting place. I think the figures would be similar if I can get a point to work.

Is there a way to project to seperate feature lines with 2 different label styles. Am able to project object to view but both have same label. Need one to have Ex. R/W and the other NEW R/W, would like to do as one change rather than change each for every view.

I have been using feature lines along buried utility locations to project these objects to section views. It works great. I created label styles, and It pops a vertical label on the section view that points toward the existing ground. I tried to use the same feature lines to project objects to profile views, and get very strange results. I do not get an option to select a label style, that field is blank, and on the profile view there is not a point where the alignment and the feature line crossed, but a line drawn all over the general area of the utility location. I have attached pdf examples of a sucessful section view and an unsuccessful profile view. I manually added the "EXISTING WATER" label so that it's easy to locate the line representing the water line.

I have projected Civil 3D COGO Points projected to a profile. I simply want to display the Civil 3D Point Number for each point in the profile.
In the Profile Projection Label Style, the only field in the text editor that displays this point number is the "Source Object Name. This shows up as "CogoPoint 124" for point 124 (see attached). How do I make this simply say the point number ONLY, i.e. "124"?
It would be nice to program the label style to display this field, yet delete the first 10 characters of "CogoPoint x", so it only says the point number, "x"

Say I'm projecting some 3D polylines to a profile view I have, and the 3D polylines cross the alignment defining the profile view. Is there a way to format the projections such that the point of intersection is identified, and that the points will be updated if I change either the alignment or the 3D polylines?

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%. (!)

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.

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.
