|
---Purpose: defines Group, Type <402> Form <1>
|
|
-- in package IGESBasic
|
|
-- The Group Associativity allows a collection of a set

|
|
-- entity
|
|
--
|
|
-- Group, OrderedGroup, GroupWithoutBackP, OrderedGroupWithoutBackP
|
|
-- share the same definition (class Group), form number changes
|
|
--
|
|
-- non Ordered, non WithoutBackP : form 1
|
|
-- non Ordered, WithoutBackP : form 7
|
