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 :: Surface Boundary Only Showing Portion Of Surface Within The Boundary

Oct 24, 2012

I used a 2d polyline to create a surface boundary for a surface created.  The polyline is a closed loop.  For the boundary type it is outer, unchecked Non-destructive breakline, and mid-ordinate distance = 1.

My problem is that when I do this I only get a small portion of the surface to show up within my surface boundary.  If I don't have a surface boundary the entire drawing surface shows up no problem.

The purple polyline is my boundary and the light blue is the surface created within the boundary.

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 :: Extending Surface To A Boundary

Feb 23, 2013

I have survey data of the inside floor of a pond ( the pond has a flat floor ). The surface made from the survey data needs to extend to the outline of the pond instead of the outline of the survey points.

I tried the smooth surface method of kriging with a grid base and I sellected the outline of the pond for the output region and that worked somewhat but there are still gaps between the boarder and the surface.

AutoCAD Civil 3D :: Surface Profile Boundary

Aug 14, 2013

I have alignments that go in and out of a surface boundary (this is because I have a surface that represents the bottom of pavement.)  I want to show the surface profile with the gaps in the profile view (where there is no surface. However in the profile view the gaps are sometimes connected with a straight line instead of being blank.

How can I have a surface profile represent the bottom of pavement properly? (An alignment that is not fully withing the surface boundary.) I know I could add the profile multiple time with different start/end stations But, I don't want that, I want it to be dynamic, as the alignment will change.

AutoCAD Civil 3D :: Surface Boundary Blows

Aug 7, 2012

The odd shapes are outside the daylight line.  They follow a straight-line around the daylight limits (see third attached file), apparently triangulating unwanted areas.  I've used a corridor shrink wrap for the surface boundary.

What is the best bet?  I'd rather not draw a polygon along the daylight line and use it as a surface boundary, since it could change.  Setting a max triangle length in the surface does not seem to provide a desired result.

AutoCAD Civil 3D :: Applying Boundary To Surface

May 14, 2012

I have problems applying an Outer boundary to eliminate a small area within a big surface (and a few Hide boundaries within that Outer boundary): Civil 3D somehow creates extra triangles within my surface (that don't really make sense to me). I am applying the boundaries as non-destructive boundaries as I need the surface to extend all the way to my applied boundaries. The surface needs to be untouched (except applying a few Outer and Hide boundaries) as it is design data.

AutoCAD Civil 3D :: Adjusting Surface Boundary

Jun 18, 2012

I need to adjust a surface boundary. I need to remove a corrupted area in my surface. I do not need it. Is there any way to drag a boundary so I can exclude some of my contour area? Is there a command under settings on tool space that I may have overlooked? This surface was furnished by a client so I do not want to rebuild or alter except to exclude some contours.

AutoCAD Civil 3D :: Extend A Surface To Outer Boundary

May 21, 2013

I use Civil 3D 2011. I have created a surface from a point group. Now i want to extend the surface to an outer boundary. To do so, i do the following steps:

- Select the surface and Extract the border object.
-  Create feature line from the extracted border polyline
- offset this feature line (featureoffset) to outside specifying a offset distance and  specifying the elevation difference as 0.
- Add this offseted new featureline as the boundary in the definition of the surface
- Rebuild the surface

Now when i am selecting the surface, I see that the featureline is not a part of the surface and I do not find the contours and the TIN extending to this new boundary. Also I still find the old border in the surface.

AutoCAD Civil 3D :: Creating Surface Boundary When Using OverlayWidenMatchSlope Subassemblies

Jul 12, 2012

I'm creating a corridor to widen a road on the left and right sides.  I am using OverlayWidenMatchSlope, with various other subassemblies.  In places it daylights, in places there's a cut wall modeled from generic links.  I am trying to create a good boundary for the corridor surfaces but I'm puzzled by one thing.  The OWMS subassembly has a P2 code, but the corridor will not generate a featureline connecting the P2 codes.. 

I will try adding another baseline, and a new subassembly that will just use a generic link to target the sawcut line (the insert point for OWMS).  That should give me a featureline I can use for a surface boundary.  Is there a way to generate that featureline from the inside edge (the insert point) of the OWMS subassembly?

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 :: 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 :: 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!
