Normal vector specification bytes draw only in the 16 predefined directions,
and the longest length is 15. These restrictions help make shape definitions
efficient but are sometimes limiting. Code 8 specifies the X-Y displacement
given by the next two bytes. Code 8 must be followed by two specification
bytes in the format:
8,X-displacement,Y-displacement
The X-Y displacements can range from -128 to +127. A leading + is optional,
and you can use parentheses to improve readability. The following example
results in a vector that draws (or moves) 10 units to the left and three units
up.
8,(-10,3)
Following the two displacement specification bytes, the shape returns to
Normal Vector mode.
You can use code 9 to draw a sequence of nonstandard vectors. Code 9 specifies
any number of X-Y displacement pairs. The code sequence is terminated by a
(0,0) pair. The following example draws three nonstandard vectors and returns
to Normal Vector mode.
9,(3,1),(3,2),(2,-3),(0,0)
You must terminate the sequence of X-Y displacement pairs with a (0,0) pair
in order for AutoCAD to recognize any Normal Vectors or special codes that
follow.
Quick Reference
Commands
LOAD
Makes shapes available for use by the SHAPE command.
SHAPE
Inserts a shape from a shape file that has been loaded using LOAD.
Code 00A: Octant Arc
Special code 00A (or 10) uses the next two specification bytes to define an arc.
This is called an octant arc because it spans one or more 45-degree octants,
starting and ending on an octant boundary. Octants are numbered
