Topic: Export Corridor or featureLines to XML

[cadplayer]

Hello!
I looking for possibility in C3D to export corridors to XML-file. Is here anybody which have something (program). F.ex. if I export a corridor to XML I can select corridor, but it does not export any corridor
What can I do with C#.NET(newbie)

The LandXML 1.2 Schema does not have anything relating to a Corridor. So when you include the Corridor in the Export, the Alignment(s) defining the baselines of the corridor will have CrossSects entry with a CrossSect entry for each corridor frequency line. There will also be a Roadways section with one entry for each alignment with the Design Speed data

This image shows the same drawing exported to LandXML 1.2, the one on the left I included the corridor, whereas the one on the left I excluded it.

Hi Jeff!
Thanx - understand. I can see all details from corridor in your picture too. But why isnīt possible to import same XML-export-file and get corridor as in origin file. I only get alignment and surfaces.
I didnīt understand if I open XML in editor I see Alignment->CoordGeom-CrossSectSurf-Profile the hole construction .... but Civil3d can not import these datas in the dwg back .

Annother question is, all the 3d-Objects you can create in Civil have to connect with other maschines or computersystems. Is there a program which can read a Corridor from Civil in a own system. I looks not very intressting if you only can get a surface from your corridor. Can you follow me?!

Dirk, I think that the corridor model is just more than what LandXML was/is designed for. Not sure how a corridor could be reconstructed from the section data, as the Assemblies/Subassemblies are not included in the export. I believe that the data CAN be used by survey instrument software for the task of construction staking, and that is the purpose for allowing the corridor in the export.

Hi again!
Thanks for your comments, I will see if I could do something in future with .NET. I am your opinion. Just a corridor affecting to complex to save it in a XML. I think a corridorObject in Civil looks like a datashortcut which connect alignment, profil and section. So I suppose it is not possible to see them as a coordinatefile with integrated featureLines or something like this.
In practise could it be intressting to have a more intelligent road solids as only the surface from a corridor. For example I could have all material, borders, kerbs...
So finally the materialReport from Civil could have more details.
You are welcome to my blogg, if you want follow this thread. (Maybe I have more practise in a couple of years and I donīt find this thread here anymore).
