class ChangeLevelNumber from IGESSelect inherits ModelModifier from IGESSelect
|
|
|
|
---Purpose : Changes Level Number (as null or single) to a new single value
|
|
-- Entities attached to a LevelListEntity are ignored
|
|
-- Entities considered can be, either all Entities but those
|
|
-- attached to a LevelListEntity, or Entities attached to a
|
|
-- specific Level Number (0 for not defined).
|
|
--
|
|
-- Remark : this concerns the Directory Part only. The Level List
|
|
-- Entities themselves (their content) are not affected.

---Purpose : Returns True if OldNumber is defined : then, only entities

-- attached to the value of OldNumber will be considered. Else,
|
|
-- all entities but those attached to a Level List will be.
|
|

|
|
---Purpose : Returns the parameter for OldNumber. If not defined (Null
|
|
-- Handle), it will be interpreted as "all level numbers"

---Purpose : Sets a parameter for OldNumber

---Purpose : Returns the parameter for NewNumber. If not defined (Null

-- Handle), it will be interpreted as "new value 0"

---Purpose : Specific action : considers selected target entities :

|
-- If OldNumber is not defined, all entities but those attached
|
|
-- to a Level List
|
|
-- If OldNumber is defined (value not negative), entities with a
|
|
-- defined Level Number (can be zero)

-- Attaches all these entities to value given by NewNumber, or
|
|
-- zero if not defined
