---Purpose : This selection looks at Level Number of IGES Entities :

|
|
--
|
|

---Purpose : Creates a SelectLevelNumber, with no Level criterium : see

|
|
---Purpose : Returns True if <ent> is an IGES Entity with Level Number
|
|
-- admits the criterium (= value if single level, or one of the
|
|
-- attached level numbers = value if level list)
|
|
|
|
ExtractLabel (me) returns AsciiString from TCollection;
|
|
---Purpose : Returns the Selection criterium :
