1. A method comprising:
prior to generating an object using an additive manufacturing apparatus by fusing build material within a fabrication chamber, receiving, at a processor, object model data representing the object, wherein a dimensional compensation has been applied to the object model data based on an expected object placement position;
prior to generating the object using the additive manufacturing apparatus, receiving, from the additive manufacturing apparatus, an indication of an object generation placement position within the fabrication chamber where the object is to be generated;
prior to generating the object using the additive manufacturing apparatus comparing, by the processor, the expected object placement position with the object generation placement position; and
in response to the expected object placement position matching the object generation placement position, determining, by the processor, that the dimensional compensation is valid and causing the additive manufacturing apparatus to generate the object.
