Data Structures

class IGESData_ToolLocation

This Tool determines and gives access to effective Locations
of IGES Entities as defined by the IGES Norm. These Locations
can be for each Entity :

on one part, explicitly defined by a Transf in Directory
Part (this Transf can be itself compound); if not defined,
no proper Transformation is defined
on the other part, implicitly defined by a reference from
another Entity : its Parent
Both implicit and explicit locations are combinable.

Implicit definition can be itself defined, either through the
definition of an Entity (i.e. a Composite Curve references
a list of Curves), or by a specific Associativity, of type
SingleParentEntity, by which the Location of the Parent is
applied to the Childs defined by this Associativity.
Remark that a Transf itself has no Location, but it can be
compound

This is a TShared object, then it is easier to use in an
interactive session
