I am using Civil 3D 2011 and wondering how to create just one contour on an existing surface at a specific elevation. I need to show where floodwaters would get to at a specific elevation so that contour would be the easiest way if I can contour the surface with just 1 elevation. I don't want to have to create 0.1' contours all over the site and then remove all the extras.
View 8 RepliesI created surfaces in Civil 3d 2011 for existing and proposed and I did a surface volume between them. Is it possible to create a specific contour in the volume surface that represents the fill volume elevation (daylight line I think)? My proposed surface is a flood water elevation and I need to define the boundary at that elevation.

View 4 Replies View RelatedI have drawing giving to us for a senior design project. I'm trying to create a surface to so that I can analyze cut/fill. Not sure if what i'm doing is right or wrong, I've never used civil 3d. But i'm getting break-line errors whenever i'm trying to create the surface from the contour lines.
Heres a link i took of what i'm doing on youtube [URL]........
I have a drawing set to UTM83 Zone 14 Meters and my drawing units is set to meters also. I created my surface from my point cloud. When i do the contour extract feature (surface object extract), the contours elevation is in the wrong datum or elevation? The surface contour is 620 but the same extracted contour says 188.97? Curious why this happens. It seems to me that it is back calculate elevation or datum to a different coodinate system.

View 9 Replies View RelatedSo I have an existing grade surface and I am laying out a number of different site designs. I've got all my surfaces from those site designs on different layers each displayed in a different layout. I need to label existing contours on each layout in different places. I've setup additional contour label styles (two for each design, major, and minor) and layers (two for each design, major, and minor). However, when I add labels to my existing surface, they come in on the right layer, but whenever I freeze any of the many layers my contour labels are on, they all turn off. The only workaround I can figure is to make copies of my existing surface for each design option and label each independantly. However, this is inacceptable as far as data management goes, since my one file will be hundreds of megs with all those surfaces.

I have 400 files each represent a tile of contour at 0.5m interval, if I xref all into one dwg it is extremely slow. These files have some 3d blocks which represent xyz and I made a .net program to open each file with "readdwgfile" method. However turned out that the points are not dense enough to generate the same accuracy contours as the 0.5m contours.
I am going home now to use my home computer and see if it can handle all these files xrefed and then bind and explode.
Worst case in make another program to extract only the contours and insert into a blank database. Always difficult when not given raw lidar point files.
Total size for these contour files combined is 327mb.
We have microstation capabilities not sure if it can put in the file in an easier way. I can work with the xrefed bogged down file. But is there a way to only export what's shown ? I have frozen the layers for all other objects from all the references.
I estimated total points from contours will be 20 million. Since each generate about 50000 points. Which is still workable. The computer i use in the office just make this more difficult. Slow cpu. Difficult day. Spent 7 hours programming and got it figured out but didn't solve the problem. I should have known better 20 points are not enough to generate that look in the 0.5m contours.

I'm working on a topo survey and the contours are crossing each others (See attached pic) and what I did was edit the surface by adding points. I know that these points are fake, but how does this affect the terrain surface for design point of view? I did try swapping edge and deleting lines but makes it worse. Also as you can see in the pic, I don't see the added points like it did back C3D 2008.

View 6 Replies View RelatedWhich is better to do: contour smoothing or surface smoothing? I did a little test with a surface with no smoothing, a surface with contour smoothing set to medium, and a surface with surface smoothing. The results puzzled me. The contours in the surface with no smoothing matched the contours of the surface with surface smoothing. The profiile of the surface with no smoothing matched the profile of the surface with contour smoothing. Are these results typical? I was surprised that the contours of the surface with surface smoothing didn't look smoother. I was also surprised that the surface with no smoothing and the surface with contour smoothing generated the same profile.
View 3 Replies View RelatedI would like to create surface from contours and extract points (with value) from on it. I had contours in my drawing; each major and minor contours are single polyline with elevation (Z value).
If I create surface form CONTOUR, some polylines (major or minor) are not included in to surface. After the creation of surface, I tried to erase the existing contour lines (Polyline) from drawing but the surface will be disappearing.
If I create the surface from ''DRAWING OBJECTS'', I'm not able to select the polylines (attachment 01) .
I have this contour lines from dwg file (see attached) and I am trying to make a surface out of it. Initially i thought it is already a surface for C3D but i cant seem to follow tutorials. While browsing for solutions from the Internet, it seems it is not even a contour file that can be added in C3D. what is this file and how i can convert it into a surface in C3D?
View 5 Replies View RelatedIs it possible to weed contour lines displayed in a surface based on the slope? I am having an issue plotting construction plans due to steep cut slopes and flat adjacent areas. I have several cuts ranging from 33%-50% adjacent to flat areas around 1%. Due to the drawing scale required by the client and the .2FT and 1FT contours required to detail the flat areas, my steep cuts appear as dark hatches due to the tight contour lines.
View 1 Replies View RelatedHow to use the Surface Contour Label Group class in the .NET API.
My first guess was that I had to create an instance object of the class and name it, and then use a "Create" method (e.g., CreateMultipleAtInterval) from there, like this:
Dim labelgroup As SurfaceContourLabelGroup
labelgroup.CreateMultipleAtInterval(arguments)
However, this doesn't work, as Visual Studio told me "Warning: Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated."
I tried just saying:
SurfaceContourLabelGroup.CreateMultipleAtInterval(arguments)
But that didn't seem to work either. How this class works and get it to add some contour labels to a drawing?
I need to create a sub-set surface from my main surface. not sure what the vernacular is for a "subset surface" in c3d but i do have a feature line that bouinds the desired area, but that is as far as i can solve.
i did try creating a new surface - pasted the main surface in the edit definition, then deleted triangles until the boundary alighned wiht my featureline. This seemed to work, but when i view the properties of the smaller subset suface, it shows a mimum and maximum elevation that is incorrect.
I am working on a project, I was given a file with the contour already mapped out. I am tasked with finding volume of a fill I had to create. I made a 3-D polyline at the elevation I want my fill to start from and going down to my final grade. How can I make surfaces with my map. I do not have any files to make the surface off of. What is the easiest way I can make a layer, TIN has already been done but no surfaces are in the file.

The park is now broke into 5 different areas and I need to get cut and fill for each area. Is there a way to do a volume report for a particular area? I could define the area with a polyline. Or do I need to copy the proposed surface and start chopping up into 5 areas?

View 2 Replies View RelatedI am curious if it is possible to modify only specific portions of a surface? For example, I have recieved an xml surface representing FG for a project, and want to do an earthwork calculation, could I raise and lower only portions of the project say by using specific boundaries for the asphalt paving, concrete etc. and then implement the raise & lower surface feature for these portions of the FG surface.
At this time I have been creating multiple surfaces for each particular feature of the site, then paste the FG surface, add a boudary and lower appropriately. Finally, I have to go through and paste each particular feature and its small surface into one "subgrade surface" to get an accurate representation. This method results in countless small surfaces and alot of leg work for something that seems like it should be simple.
I know that the surface defentions (FL's or corridors), should they be provided, would make this easy, but there have been several occasions where these are not being made availble by the project sponsor.
I followed the steps I found online to create color-specific surface labels (I assigned red to the cut elev and green for the fill elev.), but when I display them using the spot elevation on grid, I am getting both red and green elevations on same point (they are both fill elev or cut elev.), and why are there two elevations (cut-red and fill green) displaying?

I am trying to set several hundred points along polyline verticies with the point number starting at 5000. There are no other points in my drawing, yet everytime I start the process, it begins at 1. I have set 5000 at my Next Point Number under Point Identity in the Create Points toolbar. I have also verified that the 'Save Command Settings" is set to yes under the 'Commands-Create Points'. We cannot get this to behave as desired.
This is a 2D polyline with no elevations.
How do you apply certain contour label styles to certain surface styles (i.e. When I have an existing surface i want the default contour labels to be an "existing contour" style). Right now the default is a "finished contour" label style for all surfaces.

View 2 Replies View RelatedI have a grid survey of points and I've entered these points into Civil 3D. Now what I want to do is use these points to create a surface so that I can create a slope analysis of the surveyed area. My problem is that I can't get the points into a point group.
I have a generic grid (15 x 15) of points set up and I've only used a portion of them (defined by the dimensions of the site). So I want to create a surface that includes all of the points that aren't set at an elevation of 0.
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 can't seem to create a planar surface that shows up in the tool space as a TIN.
Some background, I have a TIN of a pile of dirt that I created from a point cloud (it shows up in the toolspace under the surface section). I also have a plane that intersects that dirt pile which indicates ground level. I want to be able to calculate the volume of the dirt pile by creating a volume TIN with the ground plane and pile TIN, but the ground plane does not show up in the toolspace under the surface section so I can't use it to create a volume TIN. I created the plane with the planar button in the ribbon and manually lined it up with the pile.
How can I convert this plane that is clearly in my project but not in the list of surfaces in the toolspace into a TIN to use in a volume TIN?
I'm running Civil 3d 2013 and you'll probably have to explain things like I'm 5 because I'm not familiar with the interface yet.
I have a project that I need to map the terrain as a tin solid so that I can do some cut and fill analysis. I have downloaded a orthographic and elevation data from the USGS website. I cannot get AutoCAD civil 3d to create the contours properly.
My current workflow is: use mapwspace to bring up the task pane. Connect to the geotiff image in the 1-153383539 folder. Then I try to create the contours and the option is greyed out.
