1. A method of generating tool path data to be followed by an additive manufacturing apparatus when manufacturing a physical object, the method comprising:
providing object design data in which an elongate structural feature of the physical object is represented by a line together with a specified thickness for the line;
discretizing the line to generate a first layer point that lies within a first build layer of the additive manufacturing apparatus and a second layer point that lies within a second build layer of the additive manufacturing apparatus;
projecting the second layer point to a projected layer point that lies within the first build layer of the additive manufacturing apparatus; and
connecting the first layer point to the projected layer point to provide tool path data to be followed by the additive manufacturing apparatus when depositing or solidifying material for the first build layer of the additive manufacturing apparatus.
