AutoCAD Civil 3D :: Corridor Surface Doesn't Fully Update?

Feb 18, 2010

I have a corridor that uses the Urban Sidewalk subassembly along the streets. During my rough design phase I set the outside boulevard widths to 2.00, and create a corridor surface using the Top Links as breaklines. I then do my lot grading, using that surface as a surface pasted into my FG surface. All of my side yard swales go up to the edge of the corridor's boulevard, with the elevation set 0.20 below the corridor surface. Once all of the design is done, I go back to the corridor and change the boulevard width to 0, thus forcing those side yard swales to now go up to the back of walk.this creates a small depression where we place small drain inlets.

Herein lies my problem, when I change the boulevard width from 2 to 0, the corridor surface never changes to reflect the 0' width. It's as if the break lines that I told the surface to use from the Top links are holding fast. The ONLY way I have been able to get the surface modeled correctly is to completely delete the corridor surface and create a new one and recreate the boundary, which I then need to re-paste and move to the top of the Edits in my FG surface. Just deleting and readding the Top Links from the corridor surface definition does not solve this.

the corridor-created breaklines do not get revised when the corridor changes, and cannot be edited/deleted by the user. Perhaps I am doing, or not doing, something that is forcing these breaklines to persist..

AutoCAD Civil 3D :: Sampled Surface Profile Doesn't Update When Alignment Moves

Sep 13, 2013

It is 27 miles of waterline broken into 3 mile segments.The problem is with the profiles that have been cut. The existing ground surface has been sampled along the alignment and multiple profile view made from that alignment. When the alignment changes, the only way that the surface seems to update is to run the "profiles; create profiles from surface command again" at which point it adds a new profile into the profile views reflecting the current surface over the alignment, then the "old" profile must be deleted from the profile views. Everything is set to dynamic, yet certainly is not being very dynamic.

AutoCAD Civil 3D :: Corridor Not Fully Showing In Cross Sections?

Jul 30, 2012

I have a corridor with two baselines, one on the south side of the road, and one on the north side.  The south baseline appears correctly in the section view.  It is an asphalt bike trail with a ditch to the left side.  The north baseline was not appearing at all.  The assembly was just a ditch with nothing else.  I changed the north baseline to use the same assembly as the south to troubleshoot.  The pavement comes in, but the ditch still does not appear.

I can see the ditch feature lines on my corridor (see attached), but they are not appearing in the section view.

AutoCAD Civil 3D :: Surface Corridor Is Not Triangulating Entire Corridor Boundary

Sep 14, 2012

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.

AutoCAD Civil 3D :: Corridor Surface Is Not Matching Corridor Top Links

Mar 21, 2013

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.

AutoCAD Civil 3D :: Adding Corridor Surface To EG Surface

Mar 6, 2012

I am trying to visualize a road project. The problems is, whenever the corridor surface goes below the EG surface (when the road is in cut) the EG surface is the only visible surface.

I sort of need to subtract the corridor surface from the EG surface, or merge the both surfaces into one.

AutoCAD Civil 3D :: Update Intersection Regions And Rebuild Corridor

Apr 5, 2012

I have 5 intersections in a drawing and i try to update all the intersections regions one after the other with "Update Regions and Rebuild Corridor". The problem is that sending up to date some intersections send other intersections (previously updated) out of date. So i cannot have all my intersections updated. The only way i found to correct this is to "Update regions automatically". but this way i cannot make changes to regions manually.

AutoCAD Civil 3D :: Creating Surface From Corridor

Jul 11, 2013

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.

AutoCAD Civil 3D :: Incomplete Corridor Surface

Mar 2, 2012

I have one corridor with several baselines. I have asked it to generate a corridor surface but it has left out several baselines from the surface. I have ruled out assemblies. I am not sure what is going on. I am also unable to get feature lines from this portion of corridor as well. The corridor builds just fine and I can see what the daylight lines are etc. What's going on. Yes I have audited the drawing.

AutoCAD Civil 3D :: Corridor Surface Settings

Mar 29, 2012

After you go thru and setup all of the links and feature lines that you want to use to create a corridor surface, is there any way to save that particular setup to be used on other corridors?  That way you would not have to select all of them again and again, every time that you wanted to create, say a datum surface.

AutoCAD Civil 3D :: Corridor Surface Boundary

May 22, 2012

When I create a corridor surface I usually create a suface boundary automatically by daylight.Half the time this works fine, half the time it doesn't work at all. If I view the corridor in 3d view it looks fine.

I tried to create a shrinkwrap polyline to use as a boundary but when I picked the corridor in the shrinkwrap command

it locked up my computer. These are just simple corridors with no intersections. Why the automatic boundary only works intermitently? Is there a better/easier way to create the surface boundary?

AutoCAD Civil 3D :: Holes In Corridor Surface?

Jun 21, 2013

I've created a corridor with kerbline widths targeting featurelines.  I've created the corridor at 1m centres and have added a number of individual points to ensure it properly picks up all of the geometry of the target featurelines.  However, the surface that has been created has numerous holes in it along one side and I can't understand why.

AutoCAD Civil 3D :: Corridor Feature Lines Don't Update With Code Set Style

Nov 7, 2013

How do i get the feature lines in my corridor to change their style based on the code set style selected?Whats the point of defining featureline styles in the code set style if they don't change in the corridor? They only get used when you first create the corridor?

Is there something I am missing or is this the intended workflow?

AutoCAD Civil 3D :: Corridor Surface Won't Form Correctly

AutoCAD Civil 3D :: Surface From Corridor Loses Definition?

Oct 31, 2012

C3d 2011 updated to all service packs

39 meg overlot design file

I have had this issue at least 3 times and twice on the same drawing.  I create a surface from corridor and add several polylines and feature line as well as a boundary to the surface.  Randomly it will lose all definition (breaklines and boundary) and i will have to "select similar" (and hope I get everything) and add all of my definition back.

It seems to only occur on large files and when my frequency is tight on curve and vertical curves.

AutoCAD Civil 3D :: Contours Disappear On Corridor Surface

May 14, 2013

I built a corridor, then corridor surface.  Then I changed the corridor onto a different profile.  I noticed that the contours at the end were going crazy: the new profile ended before the corridor and everything was going down to zero elevation.  So I went to edit my corridor region.  I enter the required station, and my contours disappear.

Observations so far:

If I set the end of the corridor region to 2+377.91 to  2+384.54 inclusive, the contours on the surface disappear.  The triangles and boundary still display, and the surface gives a Z reading when I hover the mouse over it.  If I set the region end to something above 2+384.54 or something below 2+377.91 the contours reappear.

My profile ends at 2+383.00, and I would like the corridor and the surface to end there too!

AutoCAD Civil 3D :: Corridor Grading - Slope To Surface

Dec 12, 2013

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?

AutoCAD Civil 3D :: Corridor / Intersection Surface / Modeling

Mar 13, 2012

I have 2 roads crossing, and I have created the 2 corridors, and an intersection object created.  I split the 2 corridor regions and put the intersection in, and then closed back in the regions to the start of the intersection object (region).  Now - how do I make that all one corridor object that reacts to either of my profiles, and is only one corridor surface? - the corridor surface ignores my region boundaries  Or at least 3 objects that interact with each other properly.  Image 1 highlights the start/end of the corridor regions, and image 2 shows how the surfaces look - why doesn't the corridor surface start and end where the regions do?

AutoCAD Civil 3D :: Corridor / Surface Style To Display Slopes

Jun 6, 2013

I am looking for either a corridor style or surface style to display slopes while in plan view while working on a corridor. I know you can turn on slope arrows as a surface style, but I am actually looking for the grade to be displayed next to a slope arrow. Hopefully I am explaining it properly.

I just am looking for a better way to spot errors before putting surfaces into machine control without checking station by station in the section editor.

AutoCAD Civil 3D :: Corridor Surface Not Using Correct Subassembly Point

Apr 29, 2013

I have created a new assembly that uses a HMA dike rather than your typical curb but my surface always begins at the top of the HMA pavement rather than the top of the curb subassembly. See Picture. Where's the setting to fix this (is it a daylight setting) or it is a bigger problem in that I didn't create the subassembly or assembly correct to begin with?

AutoCAD Civil 3D :: Corridor Region Partitioning Disrupting Surface

Jul 5, 2012

I've got a corridor which builds a surface which then is integrated into my overall surface.  Until today I have been using a basic assembly which has worked fine, however today I began splitting regions where we have varying sideslopes etc.  Once I re-associated the new regions with their corresponding assemblies, my entire surface went haywire, and now seems to be ignoring several other corridors / feature lines / other grading features I have.

AutoCAD Civil 3D :: How To Generate A Corridor Top Surface Split By Material

Jun 6, 2013

I do a lot of visualization work I need a corridor top surface split by material FAST.  before I used Corridor Solids but I don't have the extension in 2013.  So I export to CivilView, so far so good, then attempt to roundtrip the mesh back in Civil3D and that is where things fall apart.

Export to DWG is not split by material

Export to 3DS results in a blank screen

Export to FBX comes in missing large chunks of mesh out of scale and in the wrong location
