Our company, was contracted to create a DTM of a residential neighborhood using our Lieca HDS C10 Laser Scanner. Utilizing the Leica software I was provided LandXML file that contained a 2ft by 2ft Mesh surface along with breaklines for the edge of roadway, driveways and sidewalks, which was imported into Civil 3D 2012.
Our client now wishes for us to provide them with a breakline for the crown of the roadway. My first thoughts on calculating such breakline was to set the Contours at an interval of 0.05' to identify the crown of the road, then drawn the break line along the crown based on contours.
Is there a way to automatically create a Breakline from Exisitng Surfaces?
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.
trying to create a model from existing polylines (at elevation). I have created a surface, went to definiltion, drawing objects, but there is no "polyline" option there. I must be missing something. How can I create a c3d model from existing polylines?
I have create my surfaces and now need a volume between to two surfaces. I created the surface by using the Surface/Create TIN Surface tool for both my OG and the surface after material has been imported. I have gone to the volume dashboard and it will not let me add existing surface. How do I calculate the volume?
They send me a file that has polylines as contours and when I try to do the surface adding contours an error appears saying that the breaklines couldn't be added because they crossed a breakline, I don't understand why.
I'm trying to create a surface under my 'existing ground' surface. There is shallow rock where one of our projects is located and using geotechnical data I want to create a 'rock surface' at the known rock elevations. I just want this surface for visual reasons and do not want it to interact with the existing ground or pipe network.
I have 4 places along the roadway where I know the rock elevations. I created new points around each known point with the same elevation so there would be more than just four points on the surface and so I could make it the width of the road allowance. But when I look back to my profile of the road, it shows the existing profile drop to the rock surface at each place that I created points for the rock elevation. Not sure how to make it so the existing ground surface doesn't pick up the new points I added for the rock elevations.
I am creating a surface from polylines and the surface is not being created per the what the polylines represent. These are simple 5:1, 3:1, and 3.5:1 slopes. The surface wants to create curves instead of straigtlines (see attached).
I'm modeling a couple different alternatives, and I want to make an inside mask on EG where my FG surface will be.
Is my workflow the problem, or are surface masks just buggy?
I've created three EG surfaces, EG-1, EG-2, and EG-3. I pasted the dref'd EG into each one, so now I have three copies of EG, one for each design option. Each surface is on its own layer.
I have three FG surfaces, one for each design, FG-1, FG-2, FG-3. I want to use the outer border of each FG in turn to make an inside mask for its respective EG surface. I can make one, masking FG-1 out of EG-1. When I move on and try to make the mask for FG-2 to mask EG-2, no mask is created. Is it not working because I pasted the same original EG into each of the three EG option surfaces? Do I need to promote the original dref'd EG and copy it two more times, so each mask is applied to a completely unique surface?
I have created 2 surfaces of a matierial that is buried, using drill hole data. I have a surface for the top, and then a surface for the bottom of this material. I then created a 3rd suface comparing these 2, creating an isopac contour showning the thickness of the material. My question is this:.....is there a way to make the zero (0) contour show up? I have a .5 contour interval, but 0 doesn't generate. Could i be missiing something in the settings?
I created a volume surface between the as-built and design surfaces, now I would like to show the points that display the cut/fill depths between these two surfaces. I tried modifying the surface property of that volume surface but doesn't seem to offer what I want.
What it is, my client has asked me create 4 different size transit frames all similar in design. Now I use the skeletal modelling technique to create all my models and this one is very easy to edit, all I have to do is change a couple of sketch dimensions and the transit frame assembly will update to suit any given size.
So, I have completed the drawings set for the first one (There is about 7 drawings in total, each containing about 5 sheets), and I would like to just copy the whole assembly and drawing set for the next frame, and I would just change the dims in the main sketch to suit the new size of transit frame that is required, BUT I dont want to alter the original frame.
Usually to do this, I would create a pack n go then open up that pack n go project in design assistant and change all the names of all the files, then place all these files into another project.
Now doing this is VERY time consuming, as if I am renaming all the files, then I am going through around 1000 files to do so!!!Even after I do all this I still run into some problems with assemblies looking for part files or idw's still picking up and showing the old project assemblies.
Is there an easier, more efficient way of doing this?Also, I would like to add that each of the 4 transit frames would have their own project BUT all 4 projects will be inside 1 parent folder within the vault. This is just the way that we structure or file system as each folder is for the entire job.
I have points in a 2012 C3D drawing and I am looking to draw 3d polylines from point to point. Ultimately I am wanting to generate breaklines for a surface from a topo. I was able to do this a few months ago and now no matter what I try nothing seems to work. When use the 3P command the Z Vertex is 0. All of the points in the drawing have elevations. I tried drawing a feature line however, the beginning elevation is saying 0. Its as if these lines do not recognize my points as having elevations.
I have been given a survey on AutoCAD which was orginally 2D with the levels written in text next to it. I changed each point (690) to include the level in the Z-direction. I am trying to calculate volumes of topsoil removal and then cut anf fill volumes.
So I opened up Civil3D in metric template and imported my drawing as I have not been given a ddata file with the co-ordinates. Unfortunately I am having trouble creating a surface between the existing points.
I am having some trouble creating a TIN from a point layer in Civil 3D 2011. Would the best course of action be to extract the points from the drawing and creating a surface from there, or is there a way to create the TIN around the existing points in Model space?
I'm much better versed in AutoCAD, but excited about furthering my understanding with Civil3D.
I am fairly new to the Civil side of AutoCAD, as I used to work primarily in Map. I am working on a street rehab project in which I need to take survey points showing existing elevations (centerline, flowline, and top of curb) and show existing profiles in a profile view. I have no problems setting up the profile view(s) or the centerline alignment, but I am having problems with creating the profiles themselves, and I have a two part question about them
Question 1: According to the user's guide, the correct way to set up an "existing" profile is by extracting it from a surface, but I don't have a surface to use. In reading through the various profile types, the best way to set up what I want seems to be by using the profile layout tools, but the help says that a profile layout is supposed to be for a final "proposed" profile, not the existing. Does this actually matter? Will I be breaking Civil functionality by creating an existing profile using the profile layout tools?
Question 2: In reading through the profile layout tools, everything seems to be centered around PVI's. Even using the "tangent tangent" method to add in points seems to only use the first and last point as controls, with everything in between treated as a PVI. If you look at the documentation here, points one and four are treated as actual elevations, while curvature occurs at points 2 and 3. In my case, since what I have is a series of actual points on a surface, each point should be an actual surface elevation with curvature occurring between points and not at them. What method should I be using to input the points in the profile?
I am working on creating an existing pipe network (stormwater) from objects, invert data, size, type and length given. M
My question is how do I know where the start and end is and if I need to create more than one network for my project. I have a current project location and I am assuming I am to create a network for the entire location?
I have attached a couple pics for you to see what I am working with at a couple different scales so you can get a good idae of my project.
In highway construction, I usually check for lowest ditch elevation and see how the existing drainage flows. Typically one would create or specify in CL profile creation with a 15m offset right and left which would then generate existing CL and 15m offset profiles in profile view. However, the 15m offset profile might not represent the lowest point in the ditch as the lowest elevation offset distance varies along the highway.
My question: Is there a way in civil 3D profile creation where it can automatically trace the lowest elevation in the ditch and plot it in profile view?
creating a existing surface single Curb/Gutter spot elevation label using two existing surface elevation points and not cogo points. I am a surveyor, and I want to be able to just click on both points one at a time (top of curb/gutter) to place the elevation label.
The Project: Determining erosion setback elevations for hydroelectric requirements: increased water levels due to flooding.
I'm trying to create a DEM from contour polylines that were downloaded from a Government website.
The 2d shp file was imported and since the area in question is relatively small I've set the contour lines to the elevations they represent by hand. Now I'm trying to create a pseudo DEM from them. I need to create a 3d surface and then from there determine a rough idea of an erosion setback at a certain elevation.
Basically, the contour lines are set to 710', 725' and 750', the elevation setbacks are around 720' and 730'. Is there a way to create a surface between the three elevations and then show single solid polygons at the 720' and 730' elevations? And further is there a way to create a polyline at those two elevations to show an approximate setback on a sketch of the area?
I'm trying to create an all new existing surface over existing ground. I have a TIN surface of the EG, and I have drawn overlay splines that describe the new surface, but how to go about creating that design surface.
It is a compound surface, open on one end and closed all around on the other, somewhat like a half of a football stadium, but with an irregular upper edge because I am needing to figure out cuts and fills to manipulate the EG into this new surface without costly major terraforming. There is about 40-50' vertical elevation between the "field" and the upper rim with a generally constant 7-10 deg. slope all around. I'm just at a loss to figure out how to approach this project, and am quite new to Civil 3D.

I mad e the mistake of creating my corridors for a large site in the same drawing, and now I would like to pull them apart into individual drawing files for each corridor. I thought that last time I tried it, the drawings or data somehow got corrupted. I am running C3D 2009.
My question is "Can I create surfaces, profiles, & alignments using AutoCad2012?"
I know if I had Civil3D2012 I could do it, but can it be done with the Regular version I should say.
At my previous job I was using Civil3D2010 (darn economy Government job did lay offs) and now I'm using CAD2012 with new employer and I'm realizing that there are a lot of functions/commands that I don't have.
I have a series of boxes or polygones that I would like the program to find the 1/2 distance and create two seperate polylines from the one object.
I have a square with pt1,pt2, pt3 and pt4 respectively. After I have ran the program it would create a diagonal from pt1 to pt3 and join the rest of the lines now to create the one polyline. Also it would do the same to create another exact polygonal shape for the other half. Thus creating two shapes of equal value from one.
