AutoCAD Civil 3D :: Corridor Model Changing Slope Grade From 1:2 To 1:2.5
Nov 7, 2013
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?

i was wondering is it possible to show slopes or grades on my surfaces , or corridors IN PLAN VIEW ?

I have a surface that I have done a slope analysis on and want to put a table showing the slope grades. I have made a viewport and would like to put the table in paperspace. However, when I zoom in paperspace and regen the table changes size. How or where do I keep the table from changing size. It wont let me scale it up or down.

I want to create a grade (without object grade) using a corridor. This is my assembly:
This only contains the sub assembly "DaylightBench" in the side right.
I have the alignment and profile. I have created the corridor.
red line= alignment
green line= feature line (code Intersecction) converted to polyline.
pink surface= surface (code TOP).
I have added a boundary for surface of type "add from polygon" and I have selected the closed polyline(green line).
However, the boundary seems doesn´t work.

i have a corridor. the corridor feature line that is supposed to hit the proposed centerline is following my existing grade instead of where the profile is. in other words, the corridor line i need at the centerline when i do "feature lines from corridor" is following my existing grade instead of the top of my road. did i accid. change something? i need it to follow the top centerline of my road. the red arrow is the line i need at the top centerline.

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 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.

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.

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.

I have slope % angles labeled on a plan, but they are too large. They are 1/8" tall, and I need them to be 3/32" tall. I have checked the style (ROMANS) to be sure the text height is set to 0", and it is. I've also ensured that these labels are on this label style.
Check the screenshot. I added 2 screenshots with a huge difference in font size just to be sure my point gets across. And, I have hit APPLY and closed the window just to be sure. You will see up top, I have it set to 3/32". Actually the text isn't showing right, it is still stuck on 1/8". But, regardless, you can see in the lower screenshot where I have changed it to 3", but the text has not changed.
As a side note, the text on the slope labels should match the height of the contour labels you can see in the screenshots.

I have a corridor model that is made up of assemblies which have different subbases (pave1, pave2 and base). If i need to get a volume calculation of each one as they compare to my EG, do i need to create a surface for each one using the appropriate link?

When a corridor has lots of variations along the outside edges of the travelway it can make corridor modeling from the centerline a cumbersome task. This is because we have to create a template and region for every scenario where the edge treatment varies from right to left.
To simplify the process I have considered creating alignments for the edges of the roadway and adding them as baselines to the corridor. This way we can create just a few assemblies for the various edge treatments and apply them independently to the left and right baselines. These assemblies would then target the centerline profile to model the crown of the roadway, just as we do for curb returns.
In my experiments it seems to work nicely, but I encountered problems when viewing cross sections and calculating quantities, since the software is designed to work from the centerline baseline. Would it make the sections work if I add an assembly to the center baseline with short segments of pavement and stretch them to the edge baselines?
Another challenge is generating the profiles for the edge of the roadway to use for the baselines. These profiles would need to follow the centerline at a given vertical offset to provide the desired crown slope. Any edits to the centerline profile would need to be reflected in the edge profiles. This could be done by creating a surface from a grading object that is built on a featureline generated from the centerline and using that surface profile for the edge of roadway baselines. Another would be to stretch the center assembly to the edge and generate a profile that way.
So my question is: can this workflow be made to work somehow?

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'm working on a grading plan which excavates down from just outside the waterline of an existing pond. When I create a surface from the grading, it looks like a whole bunch of strange break lines have been added, messing up the surface. I thought it might be the mid ordinate distance but changing that doesn't seem to fix it it. Interestingly, when I grade from the original waterline, this doesn't seem to happen.
Here is my workflow, a picture of the result is shown below.
1. Turned the current waterline into a feature line.
2. Created new feature line by offsetting outside that feature line by 3.16 ft.
3. From new feature line, grade down 10 feet at 3:1
4. Create new surface using grading.
The grading lines (shown in white) look correct. But when I create the surface (green and yellow), it is all messed up.

I have a profile set up with a surface an alignment and a Water Main. I would like to place grade breaks (Using Profile labels) every 100' along the surface however the increment field isn't available for grade breaks. Weeding doesn't work because it needs to be exactly every 100' I was thinking of creating an expression for it however I still haven't reached that level of expertise.

I noticed a post a few years ago mentioning this function wasn't available then. Is it still not available? Is there a routine? A lisp? An expression that I can make to put a slope arrow inside every tin in my surface with a % grade?

Why do profile grade markers always reset in section views? This has to have been a wish list item. lsp or software to populate these? I heard in 2014 they still disappear.

I was laying out a vertical curve in the roadway profile. I have a vertical curve of 100' in length, however immediately after that it shows a grade break. I do not want this grade break in my profile, I simply want a vertical curve with two grades on the left and right sides. How can I get 2009 C3D to remove the grade breaks? It would be very uncomfortable for someone to have to drive over these in the real world.

I was wondering if there is a way that I can take an existing grade surface and apply a designed pond surface.
Right now I have the pond as a set of 3d Polylines in the proper geometry.
I want to place the pond into this surface and cut/fill at a 3:1 from that pond to the existing surface.

We are working on a road widening scheme where one edge of the road is retained as far as possible while other edge being widened. I like to design a retained channel line by extending the cross fall between the existing center line and the exiting channel line on to the design one.
It is possible in civil 3d to extend the gradient between two feature lines at some offset from reference feature line?
