seta

       'seta' <set> 'n'|'e'|'p'|'l'|'c'|'s'|'b'|'S'|'L'|'se' <name ..>

This keyword is used to create or redefine a set (see also qadd). All entities like points or bodies and so on must be stored at least in one set to be reachable. The set ``all'' is created automatically at startup and will be open (see seto) all the time unless explicitly closed (see setc). To add entities to the set dummy type:
seta dummy p p1 p2
This will add the points p1 and p2 to the set. The following entities are known:
Nodes n, Elements e, Points p, Lines l, Surfaces s, Bodies b, Nurb Surfaces S, Nurb Lines L and names of other sets se. The program will automatically determine the type of the entities if not specified, but then the names must be unique.
