Leica viva workflow to Carlson Survey

Are Leica users all with Liscad or infinity, please? I am trying to figure out a way to export viva to Carlson, at the same time to keep the (very limited) graph and drafting function in the controller. I found out that if I open code for linework, which enables the lines in the controller, the imported dbx or txt has no description for the linework related points, as (I guess) the code is for a line, not for a point. I also tried exporting via Landxml, but obviously the curve/spline etc changed to straight lines.?ÿ

Thank you.
