I am editing terrain in Rhino (mesh object) and would like to take the edits into Qgis. How do I convert from a Rhino .3dm to a .DEM .SHP (digital elevation Model or a Shapefile). I have been looking for a solution but it seems most people do not go form Rhino to Qgis.
I have been trying to use Autocad and Autocad Civil3D as in intermediate conversion step but I am having trouble. Any suggestions?
The goal is to run sound dampening a light path simulations on the terrain, so If anyone knows ways to do that not in Qgis that would be helpful too.
