`Dave,`
`Yes I do need to know the path but it's not be totally arbitrary, it's always circular and I can specify things like the start and end points, the radius and the included angle. I have used the idea of adding an arc to the geometry (which is mentioned in the manual incidentally) but it gets very complicated when the arc I require cuts several different regions rather than being confined to one like that required for a torque calculation. In addition the method is really clumsy when I need to use several different paths in the same solution.`
