Using the COM Interops we can find the entities which were used toi create surface breaklines:
foreach (AeccSurfaceBreakline brklin in brklines) { object[] ents = (object[])brklin.BreaklineEntities; for (int i = 0; i < ents.GetLength(0); i++) { AcadEntity en = (AcadEntity)ents[i]; //do whatever with the Entity }}
I have, as yet, been able to figure out how to get the entity(ies) using 2012's .NET API. Is it possible, or do I have to stay with COM?
foreach (ObjectId surfId in CivilApplication.ActiveDocument.GetSurfaceIds()) {TinSurface surf = tr.GetObject(surfId, OpenMode.ForRead) as TinSurface;if (surf != null) {SurfaceDefinitionBreaklines brkdefs = surf.BreaklinesDefinition; for (int i = 0; i < brkdefs.Count; i++){Surface Operation AddBreakline brklines = brkdefs[i]; for (int j = 0; j < brklines.Count; j++){ SurfaceBreakline brkline = brklines[j]; //well, as of C3D2012 SP1 the actual entity associated with this breakline is not exposed via .NET} } } }
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?

In using 2013 I noticed when I delete a feature line which is added to a surface as a breakline it does not delete it from the surface. Even after a rebuild the surface does not update. I am having to go into the toolspace and manually delete the breaklines from the surface list.
Can you filter 3dpolylines to find which ones have a vertex at 0 elevation? I do not see the option in the Object Selection Filters dialog. We have several 3dpolys which would take a while to go through each vertex.
Using the select breaklines in the prospector doesn't do much of anything in my case. Zoom to Breakline works but how do you determine one particular breakline in the bunch if theye were never named?
I am having an issue with my contours running through my breaklines (feature lines). I have tried re-ordering the breakline, edits, etc and have also set my settings to allow crossings.
I am building a surface and have back of curb, curb face, and curb flowline going around a curve. I cannot create the lines with the usual pline as they will cross due to poor field collect. I created the curbs with multiple arcs. I was then going to change them into Feature Lines and am wondering if I can then use them as breaklines in a surface.
I am having a survey plan both with points and contour lines. Points are comming from the main road and contour from the outside areas.
I want to be able to make the surface ignoring the contours between the breaklines of the road since any contour inside professional survey is giving me errors on profiles and everything.
I have created linework using the line by object tool. I have created a surface and am trying to add breaklines by selecting some of this linework. Once I try to create the breaklines, it says that all those breaklines contain errors and have not inserted them into the drawing.
Dealing with an old topo. Building a surface from a point group of points in the drawing, and 2D polyline being used as proximity breaklines.
Here is my list of events after I rebuild the surface:
So I went to use the 'Resolve Crossing breaklines' tool, and here's what that looked like:
So are there or aren't there?
When I use the 'Zoom to' feature, it takes me to the midpoint of a TIN line on a breakline, with no other objects around. Crossing window selection: only the surface and one polyline. I found one crossing breakline just by accident, not from either of these tools. After I fixed it it didn't change anything. I even deleted all the breaklines from the surface and added them again, closed drawing and reopened, no change.
I am using a breakline to establish contours around the foundation of a building. I've done this in the past with no problems. Now I'm getting an Event Viewer, Error message saying that the breakline wasn't added to the surface because it crossed a point or crossed another breakline. In one case there wasn't another breakline in the drawing.
I've used 3d polylines & others to establish the breaklines.
I had some inaccurate survey points in my EG. Now I have new points and breaklines. How to locate thes old breaklines either within the list or visually within my surface editing / style.
The zoom to doesn't work as there are many breaklines within the zoom extents, and 1000's of breaklines to sift through. Is there a setting somewhere in the surface where i can turn on the breaklines that have been added already to something that's visible so i can delete those out of my surface?
I'm looking for anything on this one. (Not the obvious answers thought). Delete all and replace all (not happening).
I'm somewhat new to Civil 3D 2013 and have never encountered this problem before. I've got a top slope standard breakline (dark green line) and bottom slope standard breakline (light green line) with the highest elevation for the top slope at 72' and it gradually slopes down to about 54' within a 75' span. My problem, as you can see in the screen shot below, is I am getting 54'-59' elevation contours right next to a survey point with a 72' elevation whenever I hover my mouse over one of the contours. There are no nearby points with anything near 54' even outside of the surface boundary (shown in magenta).
I have a viewport with two loading bays about 50m apart. I want to use a higher scale to make it more visible but wont fit on the page. I have seen this before but unsure as to how to do it, I want to put a breakline in the viewport so the scale can be bigger but have the same dimension distance.
create the attached sketch by civil 3d 2012 , actually I have tried many time to do it but in vain.The main point is that only single line has utilized as an alignment of corridor.
I have windows 8 on new asus laptop N56VZ. Installed civil 3d 2013 with no problems (i see some people have problems with installing) but it doesn't work normal. It crashes every time i try to edit an alignment, old or new.
I had windows 8 beta on an older asus laptop and civil 3d work there normally. Then I upgraded it to win 8 and it started crashing like described.Today i bought that new asus n56vz with windows 8 and it is crashing.
Just had to repair my installation, now I am unable to use any Civil 3D commands, anything with "AECC" in front of it is coming back with "unknown command"?
Whenever I try to use the "DWG to PDF.pc3" driver, I'm getting TIN triangles in my PDF. They don't show up in the "Print Preview", just in the resulting PDF. They also don't show up if I print directly to a printer. Only in the PDF. Never saw this before installing SP2.1.
I am a standard AutoCAD 2012 user. I am trying to edit drawings created in Civil 3D 2012. Is it possible to edit attribute information? I installed Civil Object Enabler so now I can view the information but can't seem to edit it.
I just installed Civil 3D 2012 64 bit on a new computer running Windows 8. It starts up fine, but when I pull up a drawing, about 1 or 2 minutes later, the program shuts down and I have to restart Civil 3D. I've pulled up several different drawings from different sources, and it does the same thing. First, a window pops up for a split second, and I can't read the contents of the window. Then, I get the window that says Civil 3D is shutting down.
Pros and cons of using two instances versus two windows? I ahve alignments and corridors in seperate files so I am always using both. Does two instances utilize multi-core processors better?

We just recieved 2014 C3D upgrade from 2012. I opened a 2012 dwg and saved in the 2013 file format. now when i attempt to open the drawing in 2014, C3D freezes while loading the drawing. It can't seem to get past "reading triangles from file". Weird thing is i can open a copy of the original 2012 DWG and work for minutes or hours in 2014 saving many times along the way and if i close the DWG and attemp to re-open, it freezes up everytime. I have done this same procedure with other DWG's and don't have any issues.
