engiGetEntityAttributePosition

Get a position in a step file record where the value of the attribute is stored for simple instance or for component of complex instance. In case of complex entities 'entity' is a component of the complex entity. The position is 0-based. Returns -1 if the attribute has no slot to store value (inverse, pure derived or irrelevant attribute) or when 'entity' is a complex entity.
