Hello All,
I am using InRoads (SS2), MS V8i SS3 and Trimble Business Center v5.1. I use TBC for editing surfaces and use the export function for creating a LandXML file. I use the points and breaklines option, and import it into InRoads. The edits and my surface are not matching the TIN lines in TBC. It seems they get overwritten with the Triangulate function built within MS. Is there any way to not have this happen? Or convert it from a LandXML to a dtm file so I can keep the edits?
Thank you,
Victor
Victor,
While searching for my own answers to a related question, I came across this and thought it might help you. (Refer to link for full article.)

To export intelligence with the triangulated surface, you must include the features which have names and styles.If you take the time to delete triangles from your DTM or change a triangle edge, those changes will show up in the <Faces> block in the LandXML file. If the receiving software cannot process <Faces> the triangle edges will not be used and the triangulated surface after import will not exactly match the surface that you exported. Some applications will use the <Faces> information, like Civil 3D or Trimble Business Center, but not all civil design applications use the triangle edge information, and InRoads V8i certainly does not. InRoads V8i will export <Faces> data, but will not import triangle edge information and must triangulate an imported surface itself. Differences in the maximum triangle length and deleted or changed triangles will cause the surface that InRoads V8i creates to be triangulated differently. That means that if you transfer surface data in LandXML format to someone using InRoads V8i, the surface that is received may not exactly match the surface you export. One method of forcing identical triangulation by software that does not process <Faces> data is to import the triangle edges into your surface as breaklines prior to exporting to LandXML. After importing the LandXML file, the triangulation must be performed without limiting the triangle length.
