Customize Arrowheads
You can create your own custom arrowheads.
Arrowheads are stored as block definitions. To use your own arrowhead,
provide the name of an existing block definition. For information about
creating blocks, see
Create Blocks Within a Drawing on page 669.
NOTE Annotative blocks cannot be used as custom arrowheads for dimensions
or leaders.
Arrowhead sizing relies on the overall dimension scale factor. When you create
a dimension, the block is inserted where the arrowheads would normally go.
The object's X and Y scale factors are set to arrowhead size overall scale. The
dimension line is trimmed by text gap x overall scale units at each end. To trim
the dimension line, the rightmost block is inserted with a zero rotation angle
for horizontal dimensioning. The leftmost block is rotated 180 degrees about
its insertion point.
