Classification: CPC B  G | IPC B  G

Claim 14:
15. A method as claimed in claim 9 comprising:
offsetting or thickening the surface to generate a first offset face;
slicing the first offset face to generate a first offset face layer line that lies within the first build layer;
using the first layer line and the first offset face layer line as part of a first closed contour within the first build layer;
offsetting or thickening the surface to generate a second offset face;
slicing the second offset face to generate a second offset face layer line that lies within the second build layer;
using the second layer line and the second offset face layer line as part of a second closed contour within the second build layer;
projecting the second closed contour to a projected closed contour that lies within the first build layer;
generating a first combined closed contour from overlapping parts of the first closed contour and the projected closed contour; and
using the first combined closed contour to provide tool path data for the first build layer.
