Larry Fish has released a new version of Compass on 6/21/2018 with improvements to the Shapefile Export.
"The 3D Exporter in the Viewer now creates a ".prj" "projection-file along with the other shapefile components. Also, since some programs prefer to have shapefiles zipped before they can be loaded, you have the option of creating a zip file that includes all the component files. "
If you haven't upgraded Compass in a while, in May a function to import survey data from plaintext files (e.g. CSV format), and back in January the ability to find and visualize bad loops was greatly improved.
