You can control the arrowhead symbols in dimensions
and leaders including their type, size, and visibility.
You can choose from many standard
types of arrowheads, or you can create your own arrowheads. Additionally,
you can
Suppress
the display of arrowheads, or use one arrowhead only
Apply
a different type of arrowhead to each end of a dimension line
Control
the size of arrowheads
Flip
the direction of an arrowhead using the dimension shortcut menu
NoteFlipped arrowheads maintain
their appearance in versions later than AutoCAD 2002. However, if
you edit a drawing with flipped arrowheads in a release earlier
than AutoCAD 2006, the arrowhead directions will revert to their
original orientations.
