Only Compass shapefiles *srv, *sta, *shots, *pas, *mprism and *prism contain attirbute data, which is stored in the .DBF file
Thus, other shapefile sets are excluded here.

*_3Dshots, *_3Dpas, *_3Dmprism, *_3Dprism all have identical attrbute data in DFB files, 
except prism and mprism file duplicate the shot-data eight times, and have FACE field, which contains FACE sequence of 1 thru 8.
Thus, including only including 'FrontDoor_3Dpas' set, from those four, in order to converse space
