AutoCAD Civil 3D :: Corridor Section Editor Not Displaying Daylight Lines To EG Surface

Jul 13, 2012

I'm having a random issue with the daylight ties lopes not tieing to the EG surface at all stations in the Corridor Section Editor. Some stations daylight fine. In plan view the daylight lines vary left & right as expected but don't display at all in Section Editor.
Some background info:2012 Civil 3D SP1 / 64 bit / WIN7Simple corridor used1 alignmentSame fg profileSame drefd EG surface (set all targets for daylight LT/RT)Only one assembly applied to entire corridor Attached are 2 captions of the issue I'm having which each have a cut & fill occurrence as well as a caption of the entire align. & corridor. I did try deleting corridor & recreating and even recreated a simpler assembly and still have the daylight issue in same areas of corridor.

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 :: Edit Corridor Surface Manually By Editing Points

Oct 4, 2013

I was trying to edit a corridor surface manually by editing points and tin lines but for me its much easier to edit the contours itself so I explode the surface into polylines and fix the contour issues but when i make it into a new surface the Surface does not look clean anymore. When I look at it in the object viewer it looks rough and jagged and doesn't look like a road at all, however my original corridor surface did look clean with perfect roads and cul de sacs i just wanted to fix the contours outside the road. I tried extracting it like i should have done in the first place but when i add the contours to a surface it still looks ugly and jagged. Another thing is that when you look at it in 2D or plan view the contours look exactly the same but when i look at it from a perspective view or 3D that's when you see the difference.

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 :: Query Point Cloud Boundary Then Add All Points Within Boundary

Nov 9, 2012

i need to know if there is any way to control the points in the point cloud.

1. either only import the point cloud in a polyline area i specify

2. add all the points within a boundary not limited to the pointclouddensity = 100, freaking default is 15 almost cost my job today. extremely stressed out right now.

i am talking about extreme lidar surveys. 1km 1km LAS/0.5m contours/xyz files times 355 of them. covers a 2km wide corridor. but i only need 100m wide after i define the road alignment. no need to have all the extra points.

right now i densify the heck out of it and end up like 5-12m points. decent but not good enough because the geotech is bitching about that accuracy is not good for some feasibility study. or is there any software i can do this besides civil 3d.

what i want can also do is automate the 'add points to surface" under point cloud and have the software do multiple boundaries without having me baby it over the night. right now every click is 5 minutes and adds like 400k to 1 million points. Civil 3D 2012

AutoCAD Civil 3D :: Corridor Item To Continue Past Daylight Along EG

Feb 4, 2013

I have a corridor design and the corridor daylights very close to the pavement.  I need to have rock from the EOP out beyond the daylight point to a 30' offset from the alignment.  I need it to follow the EG and show a depth of 2' throughout.

I had to draw the rock shapes manually.  But I'd like to figure out how to do it using the corridor if possible.

Please see the attached image.  Everything beyond the daylight point was traced on top of the EG and then offset 2' to get the bottom.

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 :: Daylight To Surface Max Slope?

Apr 18, 2012

I'm modeling a simple corridor (12' lane 2%, 6' shoulder 6%, 4:1 to match EG).  I used the "LinkSlopeToSurface" subassembly for the 4:1 to match the EG.   Unfortunately our EG isn't always wide enough for the 4:1 slope to match it somewhere.

Is there an assembly that would use 4:1 as a standard daylight slope, but where necessary adjust the slope, max. 3.5:1, to match EG surface?

AutoCAD Civil 3D :: Add Daylight Subassembly In Order To Grade Surface?

Oct 1, 2013

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.

AutoCAD Civil 3D :: Takeoff Surface Area Of Daylight Slopes

Feb 28, 2012

What approaches are available in civil 3D to takeoff the surface area of daylight slopes?Which do you recommend for given scenarios?

I tried compute materials but the volume report for cut and fill area is zero - so either I missed something or the compute materials for surface area does not work yet. Then, I tried the QTO manager and linked the corridor codes slope_link and daylight_fill to payitems. Slope_link has a QTO of 1,458,099M2 and daylight_fill has 913.39M2; I have more confidence in the daylight_fill takeoff.

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 :: Large Surface - Converting Points To Cogo Points

Mar 5, 2013

I have a large surface (over 1.5 million points and 20 000hectares)

I need to get a point file .csv from the TIN to be able to use it in another program.

-so i've extracted the points from my surface, but they are Autocad points.

-next step is to convert them to civil 3d points.

-I can not select them all when converting them or my computer crashes.

-so i select about 25 000 at a time, the converting takes roughly 10 minutes.

and i have over 1.5 million points to do.

how can i speed this up.

will more ram useful?

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.
