Claim 17:
18. A data processing system for generating tool path data to be followed by an additive manufacturing apparatus when manufacturing a physical object, the system comprising processing circuitry configured to perform a method of generating tool path data, the processing circuitry being configured to:
provide object design data in which a wall structural feature of the physical object is represented by a surface together with a specified thickness for the surface;
slice the surface to generate a first layer line that lies within a first build layer of the additive manufacturing apparatus and a second layer line that lies within a second build layer of the additive manufacturing apparatus;
project the second layer line to a projected layer line that lies within the first build layer of the additive manufacturing apparatus; and
use the first layer line and projected layer line 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.
