TranslateMappedItem()

• Translates a MappedItem. More precisely A MappedItem has a MappingSource and a MappingTarget MappingSource has a MappedRepresentation and a MappingOrigin MappedRepresentation is the basic item to be instanced MappingOrigin is the starting placement MappingTarget is the final placement //! Hence, the transformation from MappingOrigin and MappingTarget is computed, the MappedRepr. is converted to a Shape, then transformed as an instance of this Shape
