I am using the latest version of Subsurface. I'm setting up two different project names with the for the same field for tile design. I want to export the boundary from one project and import it into the other project rather than redraw the complicated boundary in the second project. I go through the export and import steps but don't get the boundary to show in the second project. The exported boundary .shp file is 1 k in size so I think it is an empty file.
