AutoCAD Civil 3D :: Surfaceslope Arrows With % Grade
Jul 2, 2012
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?
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.
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 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.
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?
I am creating profiles and I can not get the existing grade linetype to show up as a uniformed dashed line. The layer is set up for a dashed line but the existing profile line is made up of too many nodes to make the linestyle look right.
I've got a drawing in which the existing ground is so jaggedy that I've got way too many grade breaks (see the attached image). I know I can use the weeding and eliminate the labels every 50 feet, or so, along the profile. But I need to have the ability to only show a specific grade break range. For instance, I'd like for my profile only to display grade breaks between 0% and 2% and not to display anything above 2%. I've tried making an expression, but have been hitting brick walls. I also know I can manually (use the CTRL + click) select the specific labels that I don't want and erase them, but I've got lots of these labels. Any LISP routine or an expression that can accomplish this? [URL]
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.
When we created our fist C3D template in 2007 it was possible to make a grading criteria that targeted a surface at a fixed distance. In other words, the slope was variable. Looking at it again in 2013 it appears it's not possible to creat a criteria like that. Am I missing something? Or was that option removed? .....perhaps because it was too unstable?
i've got a profile band for my finished grade profile. it works great except for where a pvi falls at a major or minor station, the profile band is blank. is there a way to get the finished grade elevation to show in the band at a pvi?

I have a regular AutoCAD line in a profile view and wondered if there is a way of labeling the grade of the line. I'd think I could use and expression to calculate it. But I don't know how to automatically adjust for the vertical exaggeration without having to have a separate expression for all possible situations.
I had thought this would work with no problem. I know the elevation I need to start an arc at and an elevation at a point along the arc. I drew that portion of the arc and then extended the arc to a line where I need the arc to end. I had expected the arc to extend along it's current grade the way a straight Feature line would. But the end dropped to 0.
I undid the extension, listed the FL arc to get the grade, extended it again and used the Elevation Editor to set the previous grade. But why didn't the extension work? I checked for other FL in the site that might cause this but there were none.
I'm building up my assembly and I want to add a daylight sub-assembly in order to grade my proposed surface to the existing surface. Typically I would have a 1:3 slope up or down. I have choosen the DaylightGeneral for this and although there is quite a few parameters to play with, I'm only interested in the up/down slope but when I put anything sleeper than 1:4 it doesn't work, I get this red line and circle.
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 made a bunch of cross sections of an EG surface and want to define an elevation label at each significant grade break. I see an option to weed by distance but no option that would allow me to place a label at where the slope changes by more than a certain percent.
I found this old thread from three years ago and the best solution to come out of it was deleting individual labels.
I'm trying to create a proposed grade surface using the grading tools. I drew the outline boundaryof the proposed surface as a closed polyline then created a feature line from it and assigned different elevations to it. When I try to select the feature line in order to create the grading, I get "THIS FEATURE OVERLAPS ITSELF AND CANNOT BE GRADED". What could be a possible reason for this?
I want to set and Elevation Point (not a PI Point) along a feature line by entering the grade from the previous point. Currently the "Set Elevation Point" command only allows entering an elevations or getting an elevation from the surface. I know I can set an elevation point and then use the "quick elevation editor" to adjust the grade, but I don't want to go through the extra step.
I am wondering why the maximum hydraulic gradline in my profile plot is not matching the maximum hydraulic grade levels reported in the report or excel spread sheets.
i created section view as in pic1. In Bands, Existing surface elevation labels at existing surface grade breaks, top of road elevation labels at top grade breaks, datum is the same. Can i add existing surface elevation labels at top of road grade breaks? (pic2)
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.
I extracted a dynamic feature line from the gutter flowline of my Corridor. I labeled Multiple Segments for the feature line with a grade and vertex style that uses the "General Segment Grade" text component.
I am overiding lane cross slopes in the Section Editior and the segment grade labels for the extracted feature line do not update after I Update Corridor in the Section Editior.
If I raise/lower the CL profile of the corridor, the label updates. Just not reacting to these Corridor edits.
Peculiar behavior: The label will update to reflect the Corridor update if I Isolate it.
