This is okay if you pick two parallel Line entities [or line segments of non-3D Polylines]. But it does not take into account whether the two things you pick on are parallel, or even straight, or that you might pick something that can't be offset [a Line in a Block or Xref, a segment of a 3DPolyline, an edge of a 3Dface, etc.], or that is on a locked Layer. For a routine that will draw an Xline halfway between ANY two parallel straight entities OR nested entities [equivalent to the intent of this Tip except for the Layer aspect and its being an Xline], OR bisect the angle between them if they're not parallel, see Tip #3756, "Bisect Angle/Spacing between Straight Entities."
