Extract Sampled Cross Sections into a text file

[Anonymous]

HI,

I want to extract sampled sections to a text file like "Station,Offset,Elevation" by C#.net

Something like tplate output in land companion,

wich functons should I have access to do above?

Hi Seyyed,

I don't see any public function available in Civil 3d .net Section object to extract these details at the moment.

FYI - Section object is not yet fully exposed in .NET API.

Did you check the following API (Civil 3D COM ) ?

IAeccSampleLineVertex:: Location Property -> Gets or sets the 3D point location for the sample line vertex.

IAeccSection:: ElevationAt Method -> Gets the cross section elevation at a specified offset.

IAeccSection:: Station Property -> Gets the cross section station distance.

I am not familiar with 'tplate output in land companion'; if this is sampling the surface along a line, then you could see the following blog post with code sample useful to you -

Want to use only StartPoint and EndPoint as input to .NET API SampleElevations()?

Does it help ?

Partha, the template in LDT was essentailly the Assembly in C3D, so I think they want to get the design data.

Seyyed, I don't have time to test this, but it looks like you can use the .net API in 2012 & 2013 (maybe earlier versions as well, I haven't looked). You will need to get the sections via the Alignment, SampleLineGroup, SampleLine, Sections, Section, SectionPoints. The section points returns a collection Point3d object which you can then use the Alignment's StationOffset() method.

Or maybe you just need to run the Corridor SectionPoints report and save it as an Excel file?

HI,

Thank you partha,Jeff_M

I'm starting C3D programing about two weeks.

I want ground point data, In LDT in cross section  menu we have a command that give us a file (attached.)

Because our company uses a Local software for analyzing Profiles sections and Volumes, we need to import ground sections to it.

So when we migrated to C3D I didnt have an option, then I used landXml and export the project to landxml and importing it to LDT for my purpose.

sorry for my poor english

I would either use the Corridor "Section Points Report" and save the results as a text file, or look at the source code for the Corridor Section Points Report's source code that ships with Civil 3D to see how we extract the data from the corridor model. If you are also looking at existing ground points, there are a bunch of examples on how to extract ground points between two points.

Hi

I have reversed question. How can I create section with a Text-File which it contains {station,offset,elevation}??

[peterfunkautodesk]

In the Points menu there is a command under "Create Points - Alignment" "Import from File" what will import points from a file with station, offset elevation format. After the points are imported, create a surface and then create sections from that surface. The alignment could be a straight line if you are only interested in the sections.

tnx peterfunkautodesk

Of course I want to use C#.net for my question and I think we have problem in creating surface from points, We must edit this surface!

[peterfunkautodesk]

I missed that this was a API question....

1. You can't make a Civil 3D section object from just points. They are dyanmic objects that are made from surfaces or corridors.

2. There isn't an API call to import a file by station offset elevation, but all the tools are in the API to do this without much effort.

3. After the points are in the drawing, they could be added to a point group and then a surface made from that

4. After the surface is made, add sample lines to the alignment (at the stations from text file)

5. After the sample lines are made, create the section and section views.

Hi
I produce a DLL which it can import sections from a text file and export section view to a text file.
 After Loading this file (section.dll) with NETLOAD command in Civil3D, you can export your section view with "Exportsec2xyzoffsta" command. This command generate a text file with PXYZ and Station format from your section view.
Another command is "CreateSectionFromFile". After running this comand, A dialog box will open and you must open your text file and select alignment and other...
Your text file format for importing sectiong must be like this:
//------------------------------
chainage83.695
-50.4085         14.0000  
-38.5566         12.0000  
-27.5584         25.0000  
-11.5134         30.0000  
0.0000         22.0831  
8.8465         16.0000  
22.8670         15.0000  
40.2376         20.0000  
48.6722         10.0000
//-------------------------------
"chainage"+Station and offset and elevation for below column.

Podés colocar un ejemplo?

no entiendo.
