Detailed Description
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

Convertion of a Location, from GTrsf form to Trsf form Works with a precision given as argument. Returns True if the Conversion is possible, (hence, <result> contains the converted location), False else <unit>, if given, indicates the unit in which <loc> is defined in meters. It concerns the translation part (to be converted.
As a class method, it can be called separately
