formats the line that designates a half view.
solid*
draws solid lines where material is present.
symmetry
draws a centerline extending beyond the part and acting
as a break line.
symmetry_iso
displays a half view symmetry line according to iso
standard 128:1982 5.5o half view symmetry lines are displayed in yellow
with thin linestyle, and the "hash" marks at the ends of the
symmetry line are also yellow with thin linestyle.
symmetry_asme
displays a half view symmetry line according to asme
standard asme y14.2m-1992ohalf view symmetry lines are displayed in yellow
with thin linestyle, and the "hash" marks are displayed in white
with thick linestyle.
none
draws the object a small distance past the symmetry
line.
note: when
set to none, it is good practice to cut the view on a datum plane that
is offset past the actual center line so the datum axis can be shown and
the location of the part centerline will be clear. the cut will always
be made on the datum plane selected.
