I find myself placing bosses with respect to center-point sketches and having to place the ribs manually using the RIB function and more sketches in parts that would require a boss with non-symmetric ribs and that assembly needs to be mirrored horizontally and/or vertically about symmetric axis'. The BOSS command would benefit from lines of symmetry settings/select like the FORM command. Creating one boss with ribs and mirror them seldom works correctly.
