AutoCAD Civil 3D :: How To Model Corridor From Edge Toward Centerline
Jun 6, 2010
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?

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?
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 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.
It can be done using the LaneFromTaperedMedian subassembly, and that there is a webcast explaining it. I have checked with Autodesk, and the webcast is no longer available. Any detailed instructions as to how to accomplish this. I'll attach an image of my median.
I've created a copy of my centerline alignment using the "Create Alignment from Existing Alignment" and was going to edit the new alignment to explore different options. But the new alignment can't be editted. It's lost something in the translation. There is no grip edit for the PI, that the original alignment has.

In plan I show a pipe main as a thick line with a certain linetype whether it be for storm, sanitary or water. I have acheived this by selecting only pipe centerline under the display tab in the pipe style editor and then under pipe centerline options specifiying a width for the pipe. I don't see the centerline options for a pressure network pipe.
I have a road with storm drain and sanitary sewer. There are three alignments, one for the road centerline, one for the sanitary sewer and one for the storm drain. I would like to label the structures with the stationing from the alignment it's on but I would also like the label to include the road centerline station perpendicular to the structure.
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?
when I created a Top surface, C3D showed me otherwise. I need a gap at an intersection. In the attached DWG the intersection corridor has been removed from view by isolate.
I used 2 seperate baselines to force the road corridor to have a gap at the intersection.
Looked OK .. except ..later .. when I created a Top surface, only the first baseline is used to create the surface, the second baseline is skipped : (
I obviously did not make a gap correctly. What is the correct way? Or.. is there no way .. must the designer create multiple seperate corridors when the road has gaps?
I am currently using AutoCAD Civil 3D 2010 for surveying work and have been trying to figure out how to use part of an existing survey of land model. I have it in a layout (paper space) and used a viewport to get the section I am after but there are some changes in labeling and minor model modifications needed to make it a stand alone model and I do not want to modify the original model to make these changes. How can I take a section like I have in view port and make it into its own model with a different scale so the changes can be made and the original model is left in tact?
I have a very basic question about creating corridors. As you can see on the attachment, i created an assembly consisting of ditch and my own polyline subassembly and turned it into a corridor. The ditch part is drawn out correctly, but the other part (supposed to be a gravel road) has only sections in certain points.
I started playing around with 3d dwf's. I'd like to share my corridors in a 3d dwf viewer or something similar but when it opens in design review, everything is skewed/ jagged/garbled. The other problem is that it exports everything (assemblies, alignments, sections etc.) so it make viewing navigation difficult in the viewer for people that aren't CAD savvy to begin with. It would be ideal if you could select what you want to export similar to exporting a wmf file.
How do others share 3d models with non-cad people?
We are trying to edit a small portion of an existing corridor by adding a generic daylighting subassembly. The add subassembly tool in the Corridor Section editor works, but we get an error because the new sub doesn't have a target surface specified. how to add a target for a sub that is added after the corridor was created?

When creating an alignment from corridor feature (ditch invert level), the created alignment is not following the selected line (see image bellow). The alignment seams to be created from the first point of the feature line to the last point and ignores all the other points. The vertical alignment created at the same time seams to be correct.
I am trying desperately to create a corridor in C3D 2013.
I have the requisite Alignment, Profile and Assembly, yet when I create the corridor, either nothing appears, or it creates the corridor at incorrect elevations. I have the proper elevations in my alignment.
I had a grading plan all set, with a corridor involved. Then, I received a new survey that I didn't know was coming. I need to move all of my elements to different coordinates. I can move everything except the corridor.
I only get 2 choices when selecting corridor feature line to create profile - ETW_base, and ETW_sub. My Subassembly has 2 pavement sections, a base and subbase section. I need the top of pavement profile.
I am trying yo model river corridor with 4 locks on it. On every locks different between levels is about 2-3m. I it is possible to create profile perependicular to bottom of river. How to create it?
Another question how to later connect surface. I mean Existing ground and corridor intersect. Ho to prepare later for render Existing ground with cutted corridor river? where I am below EG.
I have sevreal corridors with various spurs. The contractor wants the cut/fill volume in sections along the corridors, not one big cut/fill calc. Is there a way to do this in C3D? I have got the volume table with the chainages on, but he does not want a cumulitive figure for the whole corridor.
I am trying to create a surface from a corridor. I have a sub-assembly attached, which I believe is working correctly. I managed to create the empty surface and when I try to add surface data nothing seems to happen. I keep changing the specified code to Base which is my finished gravel structure and hit the + but again nothing seems to happen.
Ultimately I am trying to determine a volume between my corridor and original topo.
I need to design a project but ı cant..ı have two profiles in use for one alignment..ı want to use left profile for left side, use right profile for right side.and ı want to draw cross section only one..how can ı design like this project..
