Abstract: In an example, a method includes receiving, at a processor, object model data representing an object that is to be generated by an additive manufacturing apparatus by fusing build material within a fabrication chamber wherein a dimensional compensation has been applied to the object model data based on an expected object placement position. The method may comprise receiving, from the additive manufacturing apparatus, an indication of an object generation placement position within a fabrication chamber where the object is to be generated and comparing, by the processor, the expected object placement position with the object generation placement position. If the expected object placement position matches the object generation placement position, the method may comprise determining, by the processor, that the dimensional compensation is valid and otherwise determining, by the processor, that the dimensional compensation is invalid.
