When possible, draw the finish mark touching the surface to which it refers.
In a limited space, draw the symbol on an extension line on that surface or on
the tail of a leader line with an arrowhead touching the surface. When a part
requires an all over finish, notate on the drawing FINISH ALL OVER
When all but a few surfaces are similarly finish, place the finish
marks at the appropriate locations and notate on the drawing FINISH ALL
OVER EXCEPT AS NOTED.
Figure 4-41 shows how to place finish marks.
