I means X3D sorry, "r" instead of "p"

  if it worked for you are certainly luckier then me. 

  If I do '.x basic3d.C' and then try to use 'view with X3D' - nothing 
at all happens

  If you add  TPolyLine3D to shapes.C, run macros - you would see your
  line in wirframe mode ("w") but not in either of modes "e" or "r"
