AutoCAD Civil 3D :: Adding Data To A Surface / Non-Destructive Breakline
Nov 7, 2012
When adding data to a surface, there is the option to add it as a "Non-destructive" breakline. [URL] .....
What is this good for? I created a surface, copied it, and created a volume surface between the two of them. As expected, the resultant volume was 0.
I then draw a 3d polyline and snapped to elevations on the surface. I then took that 3d polyline and moved it up 5'. I then added that breakline to the surface as a "Non-destructive" breakline and the resultant volume between the original surface and the one modified with the new breakline was still 0. Absolutely no change was made to the actual surface, it just added additional triangles.
I'm trying to find a reason it's even option and I'm coming up blank. There has to be SOME reason it's there.

I am working on a 6 mile highway project whose surface file is 85MB big. So, I created a Data Shortcut of this surface and used this for creating profiles. However, at some locations the corridors go below the surface(as per their original profile) which was not intended. So, I need to restrict the surface to follow the corridors but not go beyond it.
I have created feature lines from corridors and tried to add them as breaklines to the surface. But " error adding breakline" error pops up.
Is it because I am trying to add the breaklines to the mirror surface which I created from Data Shortcut ??
Will it be useful if I copy feature lines to original surface file and add these feature lines as breaklines in that file??

I am using AC3D 2014. I have created a surface from downloaded DEM points, but, as expected, the contours are not as accurate as I would like. They vary from known elevations anywhere from a few inches to several feet.
I also have survey data from approximately 500 points which include Northings, Eastings and Elevations. Is there a way to add these points to my existing contour surface and incorporate these know NEZ points such that he contour surface is more accurate?
I have already converted my "known point" file to a .txt format with comma delimited information.

I have a point in my surface that has a bad elevation. My question is this, I unlocked the points and edited the point containing the bad elevation and I am wondering why my surface is not automatically updating. I have a breakline in the surface that uses the "bad" point and by editing the point to the correct elevation, I was assuming that my surface would automatically update, which did not happen, so I selected the breakline and edited that also to the correct elev., and the surface still did not update until I chose "rebuild surface" even though I had "rebuild surface automatically" turned on, so I am a bit confused.

I see BreakLinesDefinition prop, but only add methods.
I assume the RemoveAt is of no use, as you cannot get the objectID of each breakline to decide if its one that should be removed.
COM is the only way it seems.

i am trying to add as a breakline. i have not been able to get this particular line to work as a breakline and the surface keeps drawing triangles through the line like its not even there. The figure properties show that it is a breakline. The figure prefix database brings the line style in as a breakline from the start.

I have created a breakline from a feature line which cuts the triangles of my surface. Is there any way to create a seperate surface from the triangles inside the breakline.

After adding 9 or so breaklines, the display of my surface (e.g. contours) disappears when I add the next breakline. Based on the surface elevation shown at the pointer location, the breakline seems to have been added and the surface rebuilt.

I want delete all breakline sets of one selected surface using API.
There is "SurfaceOperationAddBreakline" but I don´t find "SurfaceOperationDeleteSetBreakline" for example.
Is there other way to delete all breakline sets of one surface?
Later, I want to create one set breakline for each layer which has been selected by user.
I know that I can use qselect, but I want do this process automatically.

I have a master shape file that contains parcel ID, owner, tax info., etc. I have another file ( access 2003 -open to better file format suggestions-) which contains parcel ID and a "yes" or " no" entry for whether or not the parcel needs a new water meter. All I want to do is add the water meter information into the other shape file. This would create one shape file with one table with all the information that I need.
Ultimately I will use the information to do a map query and find out spatially where i need new water meters.
Right now i have the master shape file connected though the “Connect to Data” feature. I also have the new data added to the drawing though the Data sources------>attach under the “Map Explorer” Task pane. I attached access file (ver. 2003 .mdb) which has two columns “Parcel ID” and “Meter”.
I right click on the shape file under the display manager and select”Create a Join;” however my water meter table is not listed as an option. Will this not work?
Plan B - I tried to Create and connect to the access file as an ODBC connection. Followed this guy’s directions to a T [URL]. But when i populate my table under the fdo connection the column headings exist ( “parcel ID” and “Meter”) but the actual data is missing. Am I missing something important?
Note: I am running c3d 2012 on a Win 7 64 Bit machine. I also removed office 32 bit apps and installed 64 bit apps to see if that would solve the problem. No go.

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.

I do a lot of hydraulic modeling and create river bed surface datafrom surveyed points. I need to be able to transfer the surface data from Civil3D to GIS effectively. The issue is that GIS does not maintain the fidelity of my surface based on the breaklines I've drawn. It triangulates based on vertices and often triangulates through the feature lines. In LDD, I was able to do address this by adding vertices to my 3D polylines in a batch-type function. That is, I could select all of my 3D polylines and add vertices to them at the same time. In Civil3D, I have to add vertices to each feature line individually.
Any way to add vertices to feature lines, or to a surface, in a more efficient manner that maintains fidelity of surface data in the transfer from Civil3D to GIS?

I am learning to use surfaces in drawing, My main aim is for volumisation tasks. I had been following a tutorial that relied on creting surfaces. i.e
1) from the home tab> Surfaces> Create Surface
2)Add data. From Modify Tab>Surface> Add Data> Point Files.
This worked for me to start with but after changing some settings (looking to display a missing toolbar, I clicked or unticked one or two boxes, Not sure where, I know silly!). The only options I have in the drop down from "add data" are: Boundaries and DEM files. All other options in the list are not clickable.
What setting I need to change or perhaps restore all settings to default. Any comments on volumisation (spoil heps, Data is x,y,Z from survey equipment.

I have created a surface with a point group. I have a few points on the edge of my surface that need to be added to the surface. I can add them to the point group, but when I updated my surface nothing happens. The triangles don't extend to my newly added points and my profile of the area doesn't show a surface where these new points should be. the new points I want to add have the same properties as the other points in the point group, they are cogo points.

I have created a data shortcut to a surface using Civil3D 2011. When I create a reference to it in another drawing, it shows up in the Prospector but nothing shows up on the screen. I have played with the surface style and made sure all the layers were on and tried closing and reopening the drawing.
I have also tried to reference it into a brand new blank drawing and I even tried to reference a surface in a different file that I have referenced several times before (in 2010). Every time I get the same results. It seems like the surface is there, but I just can't see it.

I have a surface made up of gradings and feature line that I had to come back to and edit. I picked the surface and selected go to source file and when I got there one of my infill's has gone missing and the surface has a big hole in it. The weirdness is the sheet file that refs it does not have the hole. What is that all about.
P.S. Editing a surface built up like a Rube Goldberg contraption is no fun at all. Glad my best practices are coming along since

I am working in Civils 3D 2014 and I have a survey with points already on the correct elevation layer, I have tried creating a surface from this but it does not show up.
My process:
- I create a new drawing and insert a block (my topo survey) and click explode when I do this
- I create the surface by TIN and make sure I have the correct layer for the points that I am selecting
- Click ok
- Then go into that surface and turn on all layers and refresh - still nothing
- I also made sure that my surface style was 1m contours so I would definately see this.

I have created a contour layer in MAP and need to bring the data into Civil (to create and EGL surface) which I usually I do via an alter properties query.
There is the Create Surface from GIS data in 2014 but this requires shp files so the two questions I have are:
Can the contour layer be output as shp files (and if so how)?
If yes, is this easier/more efficient than my current workflow?

I need to do a cut/fill analysis not residential site and this site has like 6 retaining walls there is a 6 foot difference in grade.
My surface is not recognizing the grade change when I make the polyline into a wall breakline.

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.

I have a 1 mile road topo coming up for design purposes. The curb is standard, but there is full curb & depressed curb. If you had your way from the CAD seat, what shots do you prefer?
Most accurate I've seen iis Centerline, Edge Pavement/Edge Concrete Gutter, Flowline Gutter, Face Curb, Back Curb. More fieldwork, but made a good product.
What I have seen is CL, EP, BC, then "let them just use a template" and several variations thereof.
I have never seen a good way to automatically offset from say BC only and handle depressed curb by field coding.

I have a Surface that is data referenced into many different drawings. On one of the drawings, the reference will not show contours until I sync. It will show the boundary. Just one of them...but I can't use sheet set manager to publish drawings since I have to open it up and sync. Is there a setting we changed? The styles are all the same. The surface is on C-Surface, the boundary is on C-Surface, the Contours are on C-Surface-MJR, C-Surface-MNR.

I am having a lot of trouble adding retaining walls to my surface. I also have to add the curbs of parking lot.
I already have the surface. However I need to tell Civil3D to stop the contours at the retaing walls and not to try to tie them in to anything else. The closest I got was using wall breaklines and I got the top of the retaining wall to have the desired elevation. However, all the contours going to the retainig wall try to go around it and tie in to something else. This ends up creating weird contours and crazy slopes.
Now for curbs, how do I tell Civil3D to jump 6" when it reaches the curb line?

When working with multiple building pads and configurations change rapidly. Is there a method to add a Block or Xref into a Civil3D Surface under Drawing Objects? If so, how could you do it.
I want to have a building block type 1 that I can update the block or xref then updates the surface rather than doing each one individually. The Block would have a FFE of 0.00 and then the stoops, etc would either be a 0.1 drop or so.

I am placing a lot of suface slope labels in my drawing (as in hundreds). The default settings force you to choose a surface, and then to place it by selecting 1-point /or/ 2 points. The CAD default is the 1-point. Is there a way to change this default to the 2-point so I dont have to change it everytime?

I can't just accept something cause it's the way it is. I like to know the reasoning behind it.
Case in point:
Why does the check box say "Non-destructive breakline?" Why doesn't it say, "Erase tin lines that cross boundary?" I doesn't seem to have anything to do with breaklines. Or am I wrong on that one?
While I'm on a roll, double negatives send me into a tailspin. Like "Disable description keys", True or False. Huh? Why not just say, "Description Keys", on or off?

I have checked my data folder and I cannot find the file Surface-7.dwg used in a surfaces tutorial. It's a multi-view block. I checked my entire hard drive and it is not there. Can the files be downloaded? I can't seem to find where I can do this.

I have a rather large project for a roadway reconstruction. Therefore, the existing utilities are in a separate drawing and the existing ground surface model is in a separate drawing. All the above surface items (curb and gutter, asphalt, concrete, signs, sidewalks, landscaping, etc..) are in the master drawing. I then xref'd in my utility drawing and though I would use data shortcuts for my existing ground surface drawing. I took the surveyed triangles (3d faces) from our raw survey drawing and copied them into my surface drawing, created a surface from the triangles, created a boundary and such. So far everything is good. I created the working folder for the data shortcuts for this project and saved the drawing and closed it. I went into my master drawing and clicked on "Create Reference". I did not promote. The reference came though and everything is fine. Now I want to add contour labels in my surface drawing which I did but they do not show up in my master drawing but the contours themselves do. Do I have to promote this drawing into my master drawing so I can create the contour labels in my master drawing? I guess that is fine but the issue is we have small areas of topo that will be added as needed down the road. If I promote the surface drawing into my master drawing then when I add topo to the surface drawing, it wont update in my master drawing.
