LandXML Export - Deleted Lines Retained

[scottbhicks]

I have created a surface and have exported it to LandXML for import into another software.  After generation of the surface, I have cleaned up the surface triangles to eliminate triangulation outside of the area of interest.  I have tried this both with deleting actual surface lines and by applying a boundary.  After I edit the surface, I export it as a LandXML and bring it into my application where the surface still has the lines outside of the area of interest that I wanted deleted.  

Has anyone experienced this before?  How did you resolve it?

What I suspect is happening is that C3D is recording that the lines were deleted in the edits section of the surface, but that the actual lines are not deleted from the surface definition.  My other software is not smart enough to figure this out from the LandXML file.  Is it possible to finalize all the edits in C3D so that upon export my deleted lines do not transfer through?  

Thanks!

Hi Scott,

I raised this back in 2011. See http://forums.autodesk.com/t5/AutoCAD-Civil-3D/Issue-with-XML-surface-file-exported-from-c3d-2010-or...

I have been very wary of tin xml's since.

Hi,

I have experienced the same for some deleted triangulation and swapped edges.

I have tried this method :

1. Delete triangulation

2. Create data shortcut of the same surface

3. Then create data reference in new file

4. Export to Land XML

This worked for me. Hope it will work for you too.

Well, I've tried both of these methods but without success. Any more
suggested approaches would be welcome.
