5.3.2 CHANGE STRING
The CHANGE STRING command is used to alter the shape of a string entity.
COMMAND FORMAT
#CHANGE STRING :Ent x1 :Loc x2 x3 ... xm xn [:Ent ... ]
The string to be changed is identified by 'x1'. The new shape of the string
is defined by the locations 'x2' through to 'xn'.
The location 'x2' is projected onto the nearest segment of the identified
string. All of the vertices from the start of the string up to and including
this point define the first section of the new string. The last part of the
string is made of all of the vertices of the string starting from the point
where 'xn' projects onto the string up to and including the end of the
string. The mid section of the string defined by locations 'x3' to 'xm' join
the first and last section of the string together to form the new shape.
( See fig. 5.13 and 5.14 ).
