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
Whether you import your LandXML file into an InRoads surface or a MicroStation terrain model (not there's any value to that with SS2), it will be re-triangulated. It doesn't matter if the LandXML file includes points and lines or points and faces or both, it will be re-triangulated based on the points and lines in the first and third cases, and on points in the second case; i.e., it will ignore the faces. When based on points and lines the differences are usually insignificant. Obviously, you're finding some significant differences in your surfaces. I know of only way two ways to force identical triangulation: export triangle edges as breaklines or import the triangles from graphics in a dgn or dwg file.
I'm not clear what you mean by your edits not matching. If edits to points or breaklines aren't carried over from TBC, I would suspect that TBC isn't correctly exporting your final surface. Edits in TBC such as flipping triangle edges or deleting edge triangles will only be exported to a LandXML file if the faces are exported. Since InRoads ignores the face definitions, those edits will not be reflected in the InRoads surface.
