DIRECT allows you to alter the orientation of dimension
arrows relative to their associated witness lines (for
linear and angular dimensions), or geometry (radius and
diameter dimensions). 

Indicate an arrow by choosing from the following options:

IN - to position the arrows inside the boundaries of
witness lines (for linear and angular dimensions) or the
reference entity (for radius and diameter dimensions).

OUT - to position the arrows outside the boundaries of
witness lines (for linear and angular dimensions) or
reference entities (for radius and diameter dimensions).
