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 865.
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.
NOTE The insertion point a block is defined with affects its placement as a custom
arrowhead on a dimension or leader. For information on changing the insertion
point of a block, see
Create Drawing Files for Use as Blocks on page 867.
If you use paper-space scaling, the scale factor is computed before applying it
to the arrowhead size value.
