Symmetry in drawings

Good Morning Everyone,

Does anybody have any experience with symmetry in drawings? We havea number of new engineers that picked up the habit of addingcenterlines to every view of a part whether or not it iscylindrical. Some will also place a "CL" symbol with "SYM" below italong the centerline. In my opinion this is poor practice...one, itis not the right line type for this and two, it is being usedwrong. I am trying to right up a paper on the correct symmetryusage in drawings for our company does anybody have any ideas. Ihave been in the field for 13 years and I have worked in manydifference industries yet I have never felt compelled to use asymmetry line in a drawing. Also, I know that SolidWorks supportsline types per ASME Y14.2 but I cannot figure out how to correctadd a symmetry line in SolidWorks, other then in sketches.

thnx in advance
