Does anyone know if its possible to convert LN3 files to an SVL as well as a TN3 to a SVD?
Did you ever get an answer for this? I am currently looking for a way to convert a TN3 file. I don't see it in 3D-Office.
You can use Topcon 3D Office to export the linework (LN3) as a CAD file and also the surface (TN3) as a CAD file (3d triangles). These can then be brought into TBC and used to create and SVL & SVD files.
