I have a surface created from a corridor. I want to export it to LandXML for
import to LDT. When I import to LDT the surface boundary does not honor the
corridor boundary. I generated the corridor boundary from the assembly
daylight lines. The surface is correct in C3D.What technique should I be
using?
1. Apply the boundary in ldt or remove the triangles.
2. If the above didin't work I would try to paste the xml surface into a new
surface in ldt & apply the boundary or remove the triangles.

The boundary that comes into Land via XML is not the boundary of the TIN in
C3D. The export routine in C3D does not honor the TIN boundary of the
surface object generated by the corridor.
I can edit the TIN in LDT but it's a lot of redo everytime the surface is
updated. I'll have to look for workarounds until the softeware has the
ability to honor the boundaries.
I ran into that problem, too. As I recall, the boundaries were in the LandXML file, it just looked like Land Desktop ignores them.
I believe what I ended up doing was using "Extract objects from surface..." in Civil 3D to extract the surface boundary as a polyline, then I copied that polyline into Land Desktop and added it as a boundary in Terrain Model Explorer.
LDT does honor the boundary that comes from
LandXML, but the boundary definition is worthless. I was going to use the very
technique you prescribe, namely generating a boundary in C3D and imporitng it
into LDT.

Are you using the same version of Civil 3d and LDT?
Have you thought about opening the Civil 3d drawing in LDT and using the
extract Civil 3d objects into Land?

I was not aware of such a tool. We are using LDT 2004 in production but I do
have LDT 2009. Do you know of any problems I might encounter if I used LDT
2009 to convert the surface data and then use LDT 2004 to detail it? I
understand the different DWG format, but I'm not sure about the databases.

The Surface databases haven't changed format since LDT1, IIRC.....maybe even
Softdesk8.
