AutoCAD Civil 3D :: Corridor Line Follows Existing Grade
Jan 11, 2013
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.
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 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 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 am trying to label existing ground & profile grade on my cross-sections the way old Land 4 used to do it. I've muddled through section view property style settings, band settings, group properties w/no luck. It can't possible be this difficult. What am I missing?
creating a existing surface single Curb/Gutter spot elevation label using two existing surface elevation points and not cogo points. I am a surveyor, and I want to be able to just click on both points one at a time (top of curb/gutter) to place the elevation label.
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 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 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've worked with LDD for 11 yrs. Last week the IT guys changed my PC to Windows 7 64bit, so I can't have LDD and I have to work with C3D. so I am following software tutorials.
Corridor is created with daylights ,but I don't see existing ground in corridor section editor.
There is nothing about this in tutorial. Also I don't know how to calculate the volumes, in LDD after this stage we could calculate the volumes. i think in C3D I should do more for calculation.
How to prepare for rendering Existing ground with cutted corridor river? Specially in places where corridor river is below EG. If there is some tool like cut?
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 am building a corridor with the right side of the pavement fitting to the existing surface.The subassembly used to link the edge of pavement to the existing ground is LinkSlopeToSurface.
On the corridor created, the feature line (code P2) of the corridor surface (top) starts from the station 0+025, instead of 0+000.
I was wondering why there is no feature line P2 for station range 0+000 to 0+025? Does that mean the linkage to the existing ground surface not exist for the slope defined in the subassembly?
I've been researching the options to deal with tessellation of my corridor. I see the option to extract feature lines from the corridor and to maintain a dynamic link.
I've now found a link in the docs for converting tessellated lines to arcs. Can I use this command with a dynamically linked FL? And will it maintain the dynamic link? [URL] ....
I created an assembly using BasicLaneTransition. When I apply it to my corridor I am not getting a feature line at the crown (center) of the road. I have used this subassembly on several other projects and have not had this issue. The only difference I can think of is that the other projects we started in C3D 2009 and this one is in 2012.
How do I get my feature line to show without adding a marked point?
I have created Road 1 and assigned Feature Line Styles in the Feature Lines tab of the Corridor Properties and it looks as I expected.
When I go to Road 2, 3 etc I have to manually assign the Feature Line Styles again, so the question is can these feature line styles be assigned via a code set or something.

I cant seem to target a corridor FL and keep it linked to the corridor. Is this the expected behavior? I would think you should be able to, no? For that matter I would think you should be able to pick the cooridor link directly, no?

Is there a way to be able to choose a desired feature line when extracting from a corridor? For example, when subgrade and finished grade are on top of each other, it seems subgrade is always coming as default for extraction. I'm not getting the option to select the desired point code as usual for some reason. The best way I found is by turning off the subgrade feature line from the corridor properties, which is a bit tedious.
I have daylight_cut at say station 100, then sampled every 20m, however it connect from station 100 all the way to 1000 for example. because there is no such code in between. why can't it create seperate features lines? the thing is sometimes it does it and sometimes it doesn't.
see the redline cutting across the corridor? shouldn't be there.
I was looking through the docs and all it says is that this eliminates tessellation. I understand that and that's what I'm looking to do. But the docs don't give any guidance on what these numbers are for.
I'm talking about the three options under the "Smoothing" group - "Horiz Deviation", "Weeding" & "Arc Inclusion" (I'm looking at the 2010 docs as that's all I could find at the moment).
I have grading style set up to create a cut/fill boundary and the same thing for my corridor. I made surfaces from my grading and corridor and no longer need them. I need to keep the cut/fill lines for my design. How can I extract these lines from these objects? I tried keeping the grading/corridor on one layer and lines I wish to use on another so I can turn pieces of the grading off. However, it will not print the cut/fill boundary without printing all the feature lines created from a grading.
I have problem with corridor surface boundary , in curve boundary line is jumping on daylight fill , but i have created surface on wearing layer ,also when i am adding boundary there is only 3 types of adding , corridor extends , polygon and interactively , photo attached.
I created a road centerline profile and corridor and then created a profile of the two curb lines from the corridor. The road profile that I made has a vertical curve in it but the curb profiles do not show that information, just grade breaks every 25 feet based on the corridor sampling distance.
I would like to have the vertical curve information on the curb profiles.
