@Line (a macro for @Link path { line }) has pathwidth parameter:

  import @Geometry
  named pathwidth
      named thin   { 0.04 ft }
      named medium { 0.08 ft }
      named thick  { 0.12 ft }
  { pathwidth }

so you can give your @Line pathwidth { thick } or pathwidth { 0.3 ft }.

I'm not sure I understand.  Perhaps User's Guide section 9.10 "Expert
usage: defining new shapes" (p.221) is what you are looking for?
