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.
View 2 RepliesI 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.
View 2 Replies View RelatedI 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.

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 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 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 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.

Im currently using an addon for Civil 3D called Novapoint. It allows me to create 3D models of surfaces made out of 3d faces and easily models cut and fill 3d-models for me.
The only thing i need to create a cut and fill model is one or several ground surfaces (existing ground, earth layers, rock etc. whatever i need) and a closed polyline/3Dpolyline that represents the level I want my cut and/or fill model.
I enter the spcifications I want such as; earth cut angle, rock cut angle, fill angle, select which surfaces i want to include in the model calculation and select the polyline.Novapoint then calculates the cut/fill model from the surfaces to the polyline and models the different cut/fill angles and gives me the results in a 3d-face model and a specification of the volyme of rock cut, earth cut an fill.
1. Novapoint is quite unstable and crashes alot
2. You cant create profiles out of 3d faces
3. Novapoint does not automaticly combine the start surfaces with the modeled cut/fill surface
4. A large surface made out of 3d-faces demands alot of computer power
So I want to how I do the same that Novapoint does for me in Civil 3D? (I have access to Civil 3D 2007-2013 depending on which one you're using)I know I can take the 3Dfaces i created in Novapoint and make a surface in Civil 3D with them but I want to exclude Novapoint completely.
I want to create cross sections in a blank drawing via a Data shortcut Project.
My intent is to keep my file size to a minimum. I can include surface, alignment and profile per data shortcut but not my corridor. My corridor is 3000 feet long and when I do cross sections in the same drawing, it runs real slow.
Is it possible to have the production tool for cross sections create separate sheet drawings, rather than creating multiple sheet layouts in one drawing?
View 3 Replies View RelatedI'm trying to create a feature line to use as a breaklline for the bottom of a ditch. I click on the first contour, elev.678, accept the elevation, click the next contour, select T for transition, then accept the elevation, 677. I would like to end up with a feature line having a first node elev. 678, end node elev. 677, slope -4% (contours are 25' apart). Instead, The first node is 678, slopes @ -1.33% to an inserted node, elev. 677.1, then slopes at -21.88% to end node elev. 677. What am I doing wrong? I don't see a lot of options here when creating (drawing) a feature line. Should I be using something else to accomplish this task?

I have a feature line in my drawing. It is one of over 1000 breaklines in a surface. I want to delete it from the surface but keep it in the drawing. How do I do this?
In 2009 this was easy. I could erase the featue line then use the OOPS command to get it back in the drawing. Unlike the UNDO command, OOPS did not put it back in the surface definition. This was a wonderful feature/bug. In 2012 OOPS behaves the same as UNDO.
I found this post regarding finding a breakline in the surface definition but that is not realistic with 1000 breaklines.
Here are a few options I have tried:
Delete all breaklines from the surface and add the ones I want. (This is my best option so far.)Copy the featureline to the clipboard, erase it, then paste it back in. (Copying feature lines to the clipboard, or wblock, is very slow. The feature line should be moved back to the orignal site.)Explode the feature line into a 3D polyline and then convert back into a feature line. (Good option but does not work well for curves.)

I would like to get original vertices(vertex) from breakline.
With SurfaceBreakline.Vertices property I can get a ObjectId collection of them but generally will contain more vertex that original vertex because it depend of "weeding factor" values and "suplementing factor" values.
How can I get only original vertex from breakline?Perhaps, API should have other property to get only original vertex from breakline.
I have a really large sphere and have put a camera on the inside to see the inside surface. I have used the normal modifier to flip the normals and so have the skin on the inside. Something is going very wrong at this point because I have this ugly shadow line that I cannot get rid of and I also seem to not be able to light this interior, when I use an omni light it makes no difference. Where am I going wrong?
View 7 Replies View RelatedOur 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.

View 8 Replies View RelatedAny experience with the Tin Surface CreatebyCropping Function.
The specific stumbling block I have come across is the best way to deal with the database that is required to export the new cropped surface to as it has to be different from the current drawing. I don't actually need the cropped surface to be saved but need to be able to adjust elevations and extract the tin from it. The tin would then be used to generate a pregrade surface in the base drawing. Previously I had done this with non-destructive boundaries but I find the cropped surface to be more accurate.

I have two separate graded levees in my drawing. One has created a surface just fine, the other absolutely refuses to generate a surface. I've deleted the grading even the feature lines and re-did them. In my grading group I have automatic surface creation checked and the volume base surface checked. I show the surface in the prospector but there is nothing there. The one levee will show contour styles but this one ZIP!

I can do an offset from Baseline, or a tie to an elevation in a profile. What I can't do is make the offset 21' from the tie location over an additional 21' to another tie point on a surface.
View 4 Replies View RelatedI 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?

This one is curved and the top of the platform has inclinations has the picture shows.
I'm having trouble on finding the best way to aproach this dump surface. I tried to start from point 2 with the curved feature line and grade back 2% till EG and then grade forward 10% till it reaches point 3 at elevation (900) , but when i grade forward the sides obviosly dont hit my EG.
I just upgraded to Civil3D 2014 and Windows 8. When I create a TIN surface using a DEM file no contour lines are displayed. Points are processed and triangles are created and can be displayed but no contour lines. Contour line layers are set to display in the style file.
View 9 Replies View RelatedI use RocTek for cut/fil calculations, but the program is old and basic, I'm trying to transition to Civil 3D 2012 right now. Typically I create "no work zones" around my building footprints, so that I can do a more detailed take-off in those areas for over-excavations and that sort of thing. Right now I'm using Civil 3D to create an existing surface, a proposed surface, and then a volume from between the two. I thought if I just traced my proposed contours over the existing within the building footprint that I would get what I was looking for. However, analysis of the cut/fill volume shows that there are still some changes being made around the edges of the building.
Is there a specific way to make a proposed surface, but leave parts of the existing surface untouched?
See attached photo. The upper middle portion of the screen is where the building is (forgot to turn on layer).
I was wondering is it possible to create a surface from a Revit model ? There are retaining walls etc in the revit model !

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.
