class Assembly from STEPConstruct
|
|
|
|
---Purpose : This operator creates an item of an assembly, from its
|
|
-- basic data : a ShapeRepresentation, a Location ...
|
|
--
|
|
-- Three ways of coding such item from a ShapeRepresentation :
|
|
-- - do nothing : i.e. informations for assembly are ignored
|
|
-- - create a MappedItem
|
|
-- - create a RepresentationRelationship (WithTransformation)
|
|
