To ensure formal drawings depict lead lines and arrows as intended, it
is advantageous to sketch the informal drawings according to the
requirements of 37 CFR 1.84 (q) and (r) which state:
37 CFR 1.84 Lead Lines and Arrows
(q) Lead lines are those lines between the reference characters and
the
details to which they refer. Such lines may be straight or curved and
should be as short as possible. They must originate in the immediate
proximity of the reference character and extend to the feature
indicated. Lead lines must not cross each other. Lead lines are
required for each reference character except for those which indicate
the surface or cross section on which they are placed. Such a reference
character must be underlined to make it clear that a lead line has not
been left out by mistake. Lead lines must be executed in the same way
as lines in the drawing.
(r) Arrows may be used at the ends of lines, provided that their
meaning is clear, as follows:
- on a lead line, a freestanding arrow to indicate the entire
section toward which it points;
- on a lead line, an arrow touching a line to indicate the surface
shown by the line looking along the direction of the arrow; or
- to show the direction of movement.
Showing lead lines and arrows exactly as you want them to appear on the
formal drawings enables the draftsperson to deliver better drawings
with
fewer revisions.
