xml conversion to microstation

[jmola]

I have a client that required us to give them a surface that they could load into microstation.  I have version c3d2010.  I gave them a land xml file.  When they uploaded it into their program, which I believe is inroads they said the contours it generation for the surface looks great in the middle, but the edges it seems to have dropped the elevations to zero.  I did make a boundary to go around the surface to clean up any errant triangulation lines.  The polyline I used is at elevation zero.  I don't know if this is causing that?  The client thinks the inroads is forcing the edges to be elev zero.  She has limited knowledge of land xml files and has never used them till now.

Does anyone know if there is something that she has to change on her end or is it my polyline causing this?

Thanks in advance.

I don't know InRoads but the problem is not likely on your end if the XML file is good. Have you tried importing the XML file into a new surface to see the results? As long as it comes in properly I would look for the problem at the other end of the chain (the end user).

jmola, InRoads uses the exterior boundary as part of triangulation.  By setting the Civil 3D surface boundary to elevation 0 it will triangulate it in InRoads to elevation 0.  Either recreate your boundary so it is at the correct Z elevation or have the InRoads user change the Feature Point Type to "Exclude from Triangulation".  If the InRoads user is new to working with LandXML files I have created a youtube tutorial importing Civil 3D LandXML to InRoads.

that was the ticket on their end.  once they did that everything worked properly.

thanks
