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 :: Creating A Surface By Manually Selecting Points

May 21, 2012

Is there a way to create a surface by manually selecting the points instead of creating a point group?  I survey stockpiles for a local construction company and calculate volumes for them. 

There may be 50 piles on one site and it would be a lot easier to create a surface by selecting the points manually instead of creating so many point groups.

AutoCAD Civil 3D :: Editing Existing Surface Using Edit Surface Command

Nov 14, 2012

I am trying to add points into a surface. I have done this before without any problems, but now I am having issues.

When I ID points which makes up the surface it gives me the correct Z level e.g. 24.5m, however when I hover over the surface it shows me the surface name and a different z level e.g. 0.65m. What is the reason for this difference in z levels? I think this may be causing the issue I am having when I add new points.

I select the surface and use the 'edit surface command' in the ribbon, choosing add point. 

When I add a point at the level I require(23.89m), it puts it in a lot higher than the surrounding area, so I tried to put the point in to the lower z levels (0.4m) it puts it in a lot lower!

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 :: Manually Input Points Of XYZ Coordinates

Jul 23, 2013

I have the following 8 points of XYZ-coordinates:

Location SampleID X Y Z Depth Elevation FGACDC-SS01 FGACDC-SS01-S1 -77.055876 39.00845 314.5 0.5 315 FGACDC-SS01 FGACDC-SS01-S2 -77.055876 39.00845 297 18 315 FGACDC-SS02 FGACDC-SS02-S1 -77.055886 39.008643 319.5 0.5 320 FGACDC-SS02 FGACDC-SS02-S2 -77.055886 39.008643 302 18 320 FGACDC-SS03 FGACDC-SS03-S1 -77.056203 39.008736 311.5 0.5 312 FGACDC-SS03 FGACDC-SS03-S2 -77.056203 39.008736 294 18 312 FGACDC-SS04 FGACDC-SS04-S1 -77.056203 39.008491 304.5 0.5 305 FGACDC-SS04 FGACDC-SS04-S2 -77.056203 39.008491 287 18 305

 These 8 points are for 4 sampling locations with 2 depths for each sampling location. I used AutoCAD 2012 a little bit before and I am new in using AutoCAD Civil 3D 2013. What are the key steps and tips of using the values of XYZ-coordinates listed the above-mentioned table to input manually into the AutoCAD Civil 3D 2013 program. Note: 4 sampling locations are in the 4 corners of a square lot and the 8 points should look like 8 corners of a box.

AutoCAD Civil 3D :: Displaying Points In Drawing As Manually Create Them?

AutoCAD Civil 3D :: Creating Points Manually From Cross Sections

Apr 12, 2013

Is it possible to create manual points from a cross section.  

For example, I want to create a surface from a sketched (hand drafted) proposed cross section by clicking on the different points on my cross section and having a point created in my plan view.

I am working with an ancient engineer who swears by hand drawing data into the cross sections, and then wants me to produce proposed contours based on this data.  I am trying to get out of writing down the Station, offset, and elevation, and then manually creating points and having to type in the offset and elevation again.

Stuck on Civil 3d 2011 (until the end of this construction season)

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

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 :: 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 :: Corridor Section Points Report

Feb 23, 2012

When creating a Corridor Section Points Report using the Toolspace>Toolbox>Reports Manager in Civil 3D 2012, the stations get listed but only a few contain point information (see attached). 

I am trying to generate stake-out data for a proposed road.  I was able to get this report to work successfully in one of the Civil 3D tutorials, so I assume that nothing is wrong with the utility.  The problem may be related to my corridor.

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.

In page 1 of the attachment you will see the names that we prefer for the different zones in our assembly as per our Standards.

On page 2 is the default names that C3D spits out as defaults (under String Cut).

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!
