special $raw_text$[lay=lay_value] point_list
Here $
can be any character and is used to delimit the start
and end of raw_text. The command embeds raw_text in the
sketch
output after performing substitutions as follows.
#
i where i is a positive integer is replaced by
the i'th point in point_list.
#{
i}
is also replaced as above.
#
i-
j where i and j are positive
integers is replaced by a string {
angle}
where
angle is the polar angle of a vector from the i'th point
in point_list to the j'th.
#{
i-
j}
is also replaced as above.
##
is replaced with #
.
The only useful option of special
is lay
.
